Quick question, if i run a 235/35/19-front and 275/30/19-rear would this screw with the gear ratio and the vdc.
If so what 19 inch tire size conbo would you recomend.

thanks.

go 245/35/19 front.

275/30/19 will work in back.

use this tire calculator

or 275/35

cause 30 is a very thin wall, and will leave a very large gap if not lowered, or lowered enought

275/30/19 is too short to run in the rear, and is actually shorter than a 245/35/19 front. Horrible size to run

That's what i figured i guess that's why most people run 255/35/ & 285/35 on 19's....

or 245/35/19 and 275/35/19. Just avoid the 30 series

My bad, that's what I really meant, I promise!
