I have a stock 2004 GMC Envoy 4x4 with 17" wheels. I'd like to change things a bit.

I purchased a set of 20" x 8.5" wheels that have a 35mm offset. Forum consensus seems to be that 275/45 is the best tire option when going with the street/SS look.

I've read through threads and checked online calculators, but would like some extra assurance. I don't know if the clearances and wheel well measurements are the same between the Envoys, Trailblazers, and SS's. Will the combination fit my Envoy?

Like many, I'm concerned with rubbing, but I'm also concerned with how far the rim/tire will extend out. One calculator said that the package will stick out 1.2" further than stock. I just want to make sure that I don't go past the fenders.

I also used the calculator to compare my new wheel with the SS wheel using the same 275/45 tire. I used 40mm offset for the SS wheel (think that's right), and it said that mine would stick out .2" more than the SS wheel.

I'm planning on a set of Cooper Discoverer HT Plus all season tires.

Thanks for the help!

Wheels

Wheel sticking out past the fender is not near as much a problem as is the clearance between front upper ball joint and tire. I am running the stock ss wheels and 255 50 20 tires and have about 3/8 in of room between tire and ball joint. Not worried about this because distance is always going to be same.
