The size of the rim won’t really matter if you keep the overall outside diameter of the tire the same as your factory tires. If your factory rims are 18 inches with a meaty tire, you can get 22s and go with a lower profile tire and keep the same overall diameter. Any way you look at it, bigger rims look great on trucks.

What size tires will fit stock rims?
If these wheel specifications are kept consistent, then your stock (OE) tires will fit the new rims equally well. If you change rim width or diameter, e.g. moving from an 18" wheel to a 19" wheel diameter, then your stock tires will no longer fit the rims. How do I tell wheel size?
What are the different tire sizes in wheel size?
Tire Size Charts by Wheel Size. 1 21" Tire Diameter. 185/60R13 = 21.7x7.3R13. 215/50R13 = 21.5X8.5R13. 225/45R13 = 21x8.9R13. 225/50R13 = 21.9x8.9R13. 255/40R13 = 21x10R13. 2 22" Tire Diameter. 3 23" Tire Diameter. 4 24" Tire Diameter.
How do I find out the diameter of my Wheels?
If you’re looking to learn the diameter of your stock vehicle wheels – sometimes thought of as wheel height, or how tall the wheel is – the easiest method is to review your tire size information. The final number in your tire size (before the separate load index and speed rating) denotes both tire and wheel size.
What does it mean when the wheels are the same width?
Sometimes the four stock wheels and tires on a vehicle are the same width. This is called a “square” setup. A “staggered” setup is a case in which the wheel and tire widths at the front and rear axles are different. For more information see Staggered vs. square tire and wheel setups.
What happens if you put a bigger rim diameter on your vehicle than stock?
If the new wheels and tires are bigger than the originals, the tires may rub against the fender well when making tight turns or when the suspension bottoms out. Speedometers calculate speed by determining the distance traveled for each wheel rotation, so a size change can make the reading inaccurate.
What is the stock wheel offset?
The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The whole point of an offset is for the end user of the wheel to know how much in inches (4+3) or in the case of millimeter offset, how many mm the wheel will stick out or suck in from the mounting surface of the hub.
Can different tire sizes fit same rim?
Wheels and tires are not interchangeable words. Tires are a part of the wheel setup. For instance, your vehicle has a set size of rims, but you can buy different sizes of tires to fit those rims, as long as the middle of the tires is the correct size.
What tire size can I substitute?
As a general rule, you want replacement tires that are within 3 percent of the diameter (height) measurement of your existing tires' diameter — assuming your current tires are what your owner's manual recommends.
How do I find the offset of my stock rims?
Subtract the smaller number from the larger number. That gives you the offset of the wheel. If the centerline number is smaller than the hub measurement, offset is positive.
How do you know if offset will fit?
Put simply, to find if your wheels will fit your car, measure the distance from your wheel's center point to where it is mounted. This is the offset. Add that to half your wheel's width to find the back space and subtract it to find the front space. Compare this to your wheel well to see if it fits.
Can you put any 16 inch tire on a 16 inch rim?
For example, a tire with the P225/70R16 91S would fit a rim with a 16-inch diameter. Take note: if you decide to change your rims' size, you will also need to get new tires that are compatible with the change in size. Tires designed to fit a 16-inch wheel diameter will not stretch to fit on new 18-inch rims.
Can I put 245 tires on 235 rims?
The quick answer is yes you can replace 245/50-18 tyres with 235/50-18 but they will have 10mm (0.4 in) smaller overall diameter. Will only slightly effect speedo and odometer - ie speedo will read about 1.5% high.
How do I know if rims will fit my car?
The two easiest ways are to check the sticker plate in your car, it should be located inside the driver side door, or look online for the vehicle specifications for your exact make and model. That should tell you the standard rim size.
Does the tire size have to be exact?
For diameter you'll need to be sure that your tires and wheels are an exact match, e.g. a 215/65R17 tire will only fit on a 17" diameter wheel. There's a bit more flexibility when it comes to wheel widths.
What wheels from other vehicles will fit your car?
Typically, you can swap your rim with the one from another vehicle. However, this depends on several factors such as the size (diameter and width), center bore, offset, and bolt pattern on the respective rims. Overall, both sides should have matching features.
Are r16 and r17 tires interchangeable?
As pointed out by DXM, the 15,16,17 isn't an interchangeable number. None of the first 3 numbers can just be changed individually.
How to find tire size?
Tire Measurement – To find the size of the tire, look at the sidewall. Every tire has this built in so it’s clear. It’s like reading the tag on a shirt. There is tire tread width, aspect ratio (the percentage of sidewall height in relation to tread width), and wheel diameter.
What affects the stance of a vehicle?
The tire and wheel placement have the largest affect on the stance of a vehicle. You can have a car lowered to the max and if the wheel sits too far inside the wheel well and it’s too small, it still looks like crap (compared to the unwritten rules today).
What is bolt pattern?
The bolt pattern is what it is. Find what it is for your car and make sure the wheel you want has the same. The center bore is typically not that important as many wheel manufacturers will include a hubcentric ring that will cover the distance between the bore on the car and the wheel bore.
Can you change the tire size in the ECU?
Some tuning devices have the ability to change the tire size in the ECU in order to calculate the new corrected speed output but if that isn’t possible for you, this is something to consider. Once you’ve measured your overall tire and wheel height, go to your car and measure the wheel gap as it currently sits.
Do you need to ask for wheel and tire combo?
The truth is, you don’t need to ask them or research, unless you want to see what a specific wheel and tire combo looks like on a car. First off, you know what your style is and what’s acceptable to you and your car. Outside of that, you just need to get down to the details.
What is the space between stock wheels and tires called?

Why are aftermarket wheels bigger?
Bigger aftermarket wheels are perhaps most often fitted to vehicles for cosmetic purposes. They can have a profound influence on the look and presence of a vehicle. Bigger wheels and the accompanying bigger tires can have a favorable influence on certain vehicle performance purposes like off-roading.
What size tires fit a 9.0" wheel?
For example a tire size 35X12.50-20 is typically fitted on a 9.0" wide wheel, therefore the tire width is 12.5" with the wheel much narrower than the tread width. For sports cars, the general rule of thumb is to match the wheel width to the tread width in inches.
How to determine clearance?
To determine clearance, an automotive professional will need to measure and evaluate the space between your stock wheels and tires and all surrounding components. Clearance should be evaluated at both the front and rear axles, and while the suspension is loaded with the vehicle weight.
What is wheel offset?
Wheel offset is a measurement from the rear (inside) the wheel mounting face to the center of the wheel. Wheel offset adjusts the wheel either inward or outward once mounted. Similar to the diameter and width, offset directly affects vehicle component clearance. AutoAnything.com.
How wide is a 225 wheel?
This is because any given wheel width can accommodate more than one tire width. A 225 millimeter section width tire, for example, can be fitted to an 8" or 8.5" wide wheel. To determine wheel width and the full specification details of your stock wheels, the dealership service department is often a good resource.
Do you take clearance measurements when moving a steering wheel?
Be sure to also take clearance measurements in the front wheel wells while moving the steering wheel from lock to lock. If you carry heavy loads or haul a trailer, and/or drive over rough roads, be sure to account for the added vehicle weight, a compressed suspension system, and an associated loss of clearance.
How to find the wheel size of a car?
First, start with the wheel size for your vehicle. You can find that on the sidewall of the tires on your original wheels or the inside frame of the driver’s door. Check out Tire Size Explained (Reading the Sidewall) for more. The wheel diameter (in inches or millimeters) is the fifth set of numbers and letters.
What does rim size mean?
What do rim size numbers mean? This number represents the distance between the two bead seat areas where the tire is sealed onto the wheel. The wheel size also includes its width and offset. The width is the distance from each bead seat (from inside to the outside).
What is the offset on a wheel?
The offset is how far inward or outward the mounting surface is in reference to the center-line of the wheel. Here's how offset determines the look of your rims. If the hub mounting surface is in front of the center-line, your rims and tire will be pulled inward. This is called positive offset.
What is the bolt pattern on a car?
Most vehicles come with a 4-, 5-, 6-, or 8-lug pattern. These bolt patterns, which are specifically spaced, help narrow your wheel or rim choices. While counting the number of bolts on your vehicle is important before buying a set of rims, it’s vital the wheels you choose match the spacing between the wheel studs on your vehicle.
Why switch out rims?
Maybe you want an extra set of wheels and tires for easy installation every winter, or you’re looking for added performance and handling. You might even be going for a specific look, including sleek and stylish or rugged and cool.
How to measure a 4 lug pattern?
To measure a 4-lug pattern on a set of rims, measure from the center of two holes across from each other. For a 5-lug pattern, measure from the outside of one wheel stud hole and the center of the opposite. And for 6- and 8-lug patterns, measure from the center of one hole to the center of the opposite wheel stud hole.
Can you have different wheels on your car?
But that doesn’t mean you can’t have different wheels or rims installed on your car or truck.
Why are cheap tires so lightweight?
Cheap tires are often lightweight, but only because they cheeped out on the sidewall reinforcement. I actually had a popular cheap tire go out of round because it was so cheaply made inside.
Why do drag cars have low profile slicks?
This is because when a drag car launches, the tire actually deforms and ripples up to create an even fatter patch of rubber on the ground and to generate 'bite' into the ground. The smaller the sidewall you use, the more likely you will spin your tires off the line.
Does a bigger tire hurt your car?
Increasing tire size usually also hurts top end acceleration and top speed as it decreases the engine's ability to overcome the air drag holding the car back). There will also be changes in your speedometer reading in most cars with different sized wheels.
Can wheel diameter be anything?
Fortunately, while wheel width is limited by suspension geometry, wheel diameter can be whatever you like, as long as it fits and you're willing to accept certain trade offs. But before you go thinking it's a total free for all, let's talk about the ways wheel diameter affects your car's performance and the trade offs you make, ...
Do smaller wheels increase top speed?
Smaller wheels improve acceleration at the expense of top end, and taller wheels decrease acceleration while theoretically increasing top speed (though in practice top speed is limited by power and drag long before tire size.
Do wider wheels increase grip?
We discovered that wider wheels do not always (and in most cases never) increase the car's ability to grip the ground in the corners and how wider tires do not necessarily put more rubber on the ground.
Is a small sidewall good for cornering?
Avoid "weird" sizes as they're expensive and you'll have few choices in performance rubber. Small sidewalls are very stiff, great for cornering "feel" but terrible for ride quality and straight line stopping and acceleration (more on that later). Stiffer sidewalls do not give any additional grip.
How wide is a 17 inch wheel?
Here, notice that we're looking at a 17-inch-diameter wheel that's 8 inches wide and has an offset of 54 millimeters. A wheel's offset is simply the distance between its centerline and its hub-mounting surface.
How to measure offset on a wheel?
Start by laying a straight edge across the rim's backside and measure the distance between its bottom edge and the wheel's hub-mounting surface. Once you know your original wheels' offset, you can determine what else might fit.
What does negative offset mean on a wheel?
Negative: A wheel with an offset less than zero positions its hub-mounting surface closer to its inboard side, giving the illusion that the wheel's been moved away from the car and increasing track width. The smaller the number, the farther away the wheel's mass will sit. Many RWD cars have negative-offset wheels.
What happens if you get the wrong offset on a tire?
Get the wrong offset and all of a sudden tires are hitting all sorts of important things, like shock bodies and fender linings. The consequences of your botched-up measurements are wheels that'll bump up against shocks or brake calipers, torque steer, and overall cruddy handling.
What does 4x114.3 mean?
All of a sudden, 4x114.3 means something and tells you that a wheel doesn't just have four lugs, but spaces them 114.3 mm apart from one another. To determine a five-lug wheel's bolt pattern, measure the distance between the center of any lug and the farthest edge of one two spots over.
How to measure hub centerbore?
Use a tape measure or an outside micrometer to measure your hub's centerbore and a tape measure or an inside micrometer to measure the wheel's. As long as the wheel's number is bigger, chances are, there's a ring adapter to make it all work. Most aftermarket wheels' centerbores are bigger than whatever your car needs.
How are bolt patterns expressed?
Bolt patterns are expressed using two numbers, the first of which is obvious and represents the number of lugs there are, and the second, which tells you how far apart those lugs are from one another.
How many widths are aftermarket rims?
As you shop for new rims you will find that most aftermarket rims are only offered in 7 inch widths. It's not as common to find aftermarket rims that are offered in 2 different widths. People get really hung up on this because it seems confusing but it really isn't if you follow the counsel we have given in this article.
How wide should rims be?
A general rule of thumb is to try and keep your rims about 1-4 inches skinnier than the width of your tires.
How wide should a tire be on a rim?

Do aftermarket rims always have the same width?
When you buy our aftermarket rims they are almost always the same width on front and rear which causes some confusion because your OEM rims are 2 different widths. Almost any new ATV or UTV will come with skinnier rims on the front vs. the rears.
Do tires have to be different widths?
Your rims do not have to be different widths just because your tires may be different widths from front to rear. Another thing to think about to help you understand this is that your tires must be wider than the rims for them to seat properly.
When considering tire size, don't use mathematics to figure it out.?
When considering tire size, don't use mathematics to figure it out. You'll figure out it's not going to equate between tires types and companies. The sizes you see on the side of the tire are more general than exact (except the wheel size, which needs to be correct).
Does the diameter of a wheel affect handling?
The diameter of the wheel does affect the handling (as you pointed out). The fact there will be more give in the sidewall can account for most of this, not the rim itself. You need to match the rim width to the tire you plan on putting onto the rim. If the tire is too wide for the rim, this can cause issues in handling.
