Your factory wheel is 8" wide with a 6.25" backspace. If you stay close to those measurements you can run a 35 no problem. It's when you get into wide rims or extreme backspaces that you will start to have rubbing issues.
Wheel specs is the most important thing to watch when it comes to not rubbing. I'm running 37''s with 3'' of lift and some parts to make it work w/o any rubbing.
Rule of thumb is to stick to a wheel no wider than 9'' and keep the BS between 5'' and 6''. The closer to 6'' the better in my book.
35'' tires look good with 2.5'' to 4'' of lift and 37'' look good on 4.5'' to 6'' of lift.
I've found that I got BETTER MPG with my 37'' tires than my 35'' tires with auto trans and 3.73 gears. Mostly street driving too. Its moslty becasue of tire/wheel weight and rolling resistance.
You can clear 35's stock if your going to stay on road.
