Hi everyone,

Not too sure about this wheel sizing so hoping you all can help provide some suggestions. I'm planning on fitting 18x8.5 +30ET front and 18x9.5 +20ET rear.
Tires planning to go 245/40/18 all around. I think based on the online calculators, these seems to be closest size without too much variance in the speedo. I'm not too sure with such low offset if it will rub in the rear... Thanks everyone in advance for your help.

 

The rears will rub for sure.......the fronts will be close...

You need offsets in the +43-+45 range for the 9.5 in the rear. You could get away with +35-+50in the front with 8.5"

 

^^^ What he said.

 

since the rear tire is stretched so much its probably going to be the rear wheel that will hit the fender

 

yea, the rear wheel is too far out.

 

with 8.5 you could go as low as +22 (roll fenders and stretched tires). with 9.5 you can go as low as +34 (roll fenders and stretched tires. you can also go 9.5 all around. 10.5 all around will work too. so many options, so many wheels, so many tires, so LITTLE money...

 

Thanks everyone !

 

I'm not sure what you are trying to do with staggered wheels but the same size tires front and back. That isn't going to work, especially with staggered diameter as well as width. Something like 245/35/18 in front and 275/30/19 in the back might be good.

 

take a knitting class instead ...
