On wheels that are 20 x 8.5 Front, 20 x 10 Rear what is the optimal tire setup.

Front = 5x112, 20 Offset
Rear = 5 x 112, 20 Offset

Option A. 255/35/20 Front, 285/30/20 Rears
Option B. 245/35/20 Front, 295/30/20 Rears

V/R

 

255/30/20 and 295/25/20

 

Thanks for your input but the only option I am considering are the two above. Out of the two I think 245/35/20 Front, 295/30/20 Rears. What is your assessment of the later?

Option B.
But S500Man is right but 245/30/20 295/25/20 would work best thats what i'm running not that much difference but the profile look of the size above make's wheel pop..............

 

im telling you the correct tire size our cars take, research previous CLS wheel posts and you will see...its all about Diameter..keeping same as stock.

 

Put 305 in the back..
