Frequently Asked Questions About Changing Wheel Size

Tuesday, January 8, 2013 by Ben Rooney

Often times I receive calls from customers who are curious about changing the wheel size on their vehicle. Here are answers to some of the most common questions about the difference in wheel sizes:

Can I use a different wheel size than what came on my car? Yes. There are often sizes that'll work very well on a vehicle even though they were not originally installed on it. When you search by vehicle on our website, all the options listed have been verified to fit. This also allows us to show you the specific price for the wheel you need for your vehicle.

Why do you need to know my vehicle? We need to know your vehicle to ensure a proper fit. Experience has taught us that searching by wheel size, offset and/or bolt pattern alone aren't specific enough criteria to ensure an exact fitment. Attention to detail prevents vibration, wheel and tire interference and unbalanced handling. Read "Why Shop for Wheels by First Selecting a Vehicle?" to see what we check so the wheels you order are a fit for your car.

How does Tire Rack know what will fit my vehicle? So glad you asked! Because there are numerous wheel/vehicle combinations, this often means each wheel has to be individually tested on the vehicle either manually or electronically using Computer Aided Deign (CAD) data. Some of the items we verify to ensure a proper fit include:

  • Bolt Pattern
  • Centerbore Diameter
  • Hub Diameter
  • Load Capacity
  • Lug Hardware
  • Suspension Components Clearance

Take a look at "How We Know What Fits" to see how we offer Tire & Wheel Packages that are specifically designed for your vehicle.

Will the new size throw off my speedometer/odometer? No. If you stick with a proper plus- or minus-sized tire, the speedometer and odometer will still function correctly. To learn more about this topic, check out our tech article, "The Plus Concept."

Will I have to change anything else on my vehicle? Typically, the answer is no. The vast majority of our wheel fitments will bolt right on. We do list some specialized wheel fitments that are designed for vehicles used in racing, with lifted suspensions or modified fenders. Any wheels requiring modification are noted as such. 

Will my vehicle's ride or handling be affected? It depends on the size. Plus or minus one inch from the original wheel is not usually very noticeable. Bigger wheels generally have sportier handling but a harder ride. Smaller wheels have a softer ride and more flex in the tire's sidewall.

I shopped for a Tire & Wheel Package, but I only see wheels. What's going on? Creating a Tire & Wheel Package is a two-part process. First, you choose the wheel you want, then you choose a tire to go with it. As tire enthusiasts, we don't believe that the same tire is right for every driver, so we let you choose the tire that's best for you.

Hi,can i use the kumho v710 tires for drag racing? and how much pressure tire can i use?.My car weights 1960 pounds with driver.Thanks.

The V710 is intended for circuit racing. It can be used for drag racing but will not be as ideal as a true drag tire. Kumho does not publish pressure recommendations for drag use on the V710.

We do not have any 17x9 to fit the Saturn. To see what we do have that fits, use the link below to shop by vehicle: http://www.tirerack.com/wheels/wtpack.jsp?affiliate=HJ7&bPostID=post-id-c036f9e3-a596-48ea-a307-0d46aa6d4aac
