if i buy a car with 15 inch tires, and I want to upgrade the size to 17 inches so I can put my rims on it, does anything else need to change about the car? Do you need to add new axles as well?

Thank you

just make sure you pick the right tires with your rims.

Generally, your profile will be much lower with 17 inch rims so body mod or axle adjustments shouldn't be necessary. however, you will have to take your car in to recalibrate the spedometer and tachometer.

If the new tire has a larger diameter or is wider than the original tires you could have clearance problems and rubbing. (tires on fenders) If it is smaller you could have scrapping problems. (under carriage on ground) Either way your speedometer/odometer will be off, but it will not effect your tachometer. Choose new tires with close to the same overall diameter as the originals and you will minimize problems and shouldn't have to change anything else.

You should be able to get a 17" tire with the same diameter as your stock setup, so everything will be fine. We usually suggest getting an allignment done though, just to make sure everything is sitting pretty

Be sure that the bolt pattern in the same, #of studs and size.
