Hey guys I have a question the rim spec is
front 20x9 38 offset
rear 20x10.5 45 offset
the car is dropped on DF210 springs , what tire sizes can I run on this set up . Thank you for your help

 

probably need to shave the rear fenders to clear. maybe 245 and 285 tires?

 

use this wheel calculator below:

input the stock configuration on the left, and the new wheel package configuration on the right. look at comments below. then readjust wheel package until you get optimal comments for your wheels.

 

Thanks guys for the help
