Hey guys, if I run 19x8.5 in the front with 245/35s and 19x10.5 with 285/35s would that be ok? Would I get oversteer or understeer? I havent gotten the 10.5s yet, I was going to get 9.5s but the rep told me to go with 10.5.

what do you guys think?

 

You would understeer relative to a non-staggered setup, but understeer itself is subjective.

 

So what would be the better setup? 8.5 with 9.5? or 8.5 with 10.5?

 

IMO you would probably want 8.5/9.5 because you will probably run a tire that is smaller (I'm running 275/35/18 on a 9.5 in the back). If you really wanted a 10.5 in the back, at least run a 9.5 in the front. That will mitigate any understeer w/a 10.5 in the back, as opposed to an 8.5 front.

 

I wouldn't mind the set-up for the street. Its fine. If this was for competition (autocross) I would not choose these sizes.
