I finally found a set of factory kk 17's to replace my factory 16's and then discovered that the factory 235/65/17 tires are actually .3 inch smaller than my factory 225/75/16 (if the internet tire calculator is correct). The same calculator says that a set of 245/65/17 tires would be .2 inch taller than the factory 16s. My question is, has anyone tried a set of 245/65/17 and do they rub anywhere on a stock KK? Any info or educated guesses are appreciated. According to the calculator the speedometer error would be less than 1 mph from 20-80.

those tires are the same width but shorter then the 245/75/16 stock KKs have rolled on. you should be fine.

dirty i think you are mistaken a 245/70/16 is stock... the size he specified is .4" taller... so it should still be fine though

I was just stating the size tires he wants to run are smaller then 245/75/16, which is the recommended largest size without lift. So it should fit fine.

oh i gotcha... i thought you were saying they were smaller then the stock tires ( which isnt true)
