I just purchased a new 2010 RS 7.0.

I would like to know what is the widest tire and wheel I can run front and rear. I have seen posts about running a 9.5" wheel in the rear. I would like to stay with either a 17" or 18" wheel (we have a LOT of pot holes in our town). The wife has already told me that I can't modify the wheel wells.

Thanks.

 

the wife told you that you cant?

back hand her

 

Considering her proficiency with a firearm, that WOULD be fatal!

 

You taught her to use a gun? Back hand yourself!

 

Worse yet, not just ANY gun................an HK MP-5 9mm submachine gun!

 

if its your daily and u have a family just go 17/18 x8 or 8.5 with a 225 or 235/40 for 18s [45 if your running 17s]

 

I like the 18x8 with a 225/40R18 on the front with a 40 offset, that is basically just tucked in the edge of the fender. Any wider or lower offset and you'll poke out some. For the rear you can go with a wider rim or lower offset. About a 10-15mm lower offset or a 9.5" width rim will come out almost perfectly flush. Or you could just add some 10-15mm spacers and run all four rims the same size. Much easier for rotating tires. All of this is dependent on how high you want to have the vehicle. I keep mine aired up about 1 1/2" above the tires so that the front doesn't rub on hard corners or large pot holes and so that it'll clear the slope up the driveway.
