First off, yes, I have searched. But I was hoping this would be a quick answer for someone. I just snagged some wheels, and i'm searching for some rubber.

wheels are 19", 8.5 front, 9,5 rear

Will I have an issues running 245's up front and 275's rear? I'm pretty sure I'll be in good shape, I just want to double check.

 

I would probably do 245/265

 

245/275 works fine. Make sure you get 35 series tires front and rear.
-GP-

 

Thanks for the input. I wanted to consider 40 series for a little more tire, but 35's are probably the way to go.

I was 90% sure I was good with 275/245, I've heard that I could even go 285 on a 9.5", but I'm gonna go with the 275/245 set up.

 

your stock wheels weren't the Rays 19s by any chance were they?

 

No, they're the stock 17's, but I am looking to sell them once I pick up some rubber and get my new wheels on. Let me know if you're interested.
