2011 Scion XB. I'm purchasing DF210's with stock everything else. I was also planning to purchase XXR 530 18x8.75 +33mm offset in the front and 18x9.75 +20mm offset in the rear. Is it possible to use 2 different tire sizes? Such as 215/40/r18 in the front and 225/40/r18 in the rear or should I get the same size all around? Anyone running this setup? Is there any rubbing?

 

I went with the same rim but 18x8.75 33 offset all the way around, with 225/40/18 tires. I'm debating whether or not to go Df or Nf springs, probably Df. I'll let you know how it works out!
