What tire size can fit to my Front Wheel: 18x8? and Rear Wheel: 18x10?

is there different thickness of tires for this wheel size? or there is just one size for a specific wheel size? ( EX: like 18x8 = one tire size only).. tnx for the answers guys. btw sorry for the dumb question, coz i dont know how to use the tire size calculator thingy. and again TNX.|||No, there are many tire sizes. If you're going with 8 inch wide rims in the front, get something like 225/40/18 tires, and for the rear 255/35/18 tires. They won't be cheap, and you won't be able to rotate them either since they are a staggered set up. You can also go narrower for a stretched look, but the tires may blow up prematurely. You can also go a bit wider too, but then you may have some rubbing issues.|||Lets break it down. Tire sizes comes speced in 3 numbers. we'll take a 255/50r15 for example. the 255 is the tire tread width, in milimeters, (how wide the tread is), the 50 is a height the width ratio, that is, in this case the tire side wall is 50% of the tread width, the R stands for radial tire, and the 15 is the rim size in inches. Yes, they combine metric and inches in all tires, don't know why. For you i would recommend a 245/50R18 for the fronts and a 275/45R18 for the rears. your best bet is to talk it over with theses guys. http://www.tirerack.com/
