Guys I Need Help. Input Please!!!

[thack82]

Okay guys I'm new to this Forum and I need your help. I bought my Wife a brand New 2007 Hummer H3 back in 2007 from Bachman Hummer. It's due a new set of tires and I want to put the biggest tires I can fit under it without any rubbing. I'm looking at BF-Goodrich AT's, and Good-Year Dura-Trac's.

I put a set of Hummer H2 Wheels/LT315/70R17 on my 2004 Silverado Straight Cab Duramax. In order to run them I cranked my torsion bars up 1.25 inches. Does the H3 have torsion Bars?

This is our primary vehicle, we usually drive it to Florida (13hrs) at least once a year. I want to make it look beefed up but I don't want to sacrifice reliability and handling characteristics would you guys go with a 285/75/R16, 295/75/R16, or 35X12.50-16's?

What about about the Speedometer/Odometer Calibration, what needs to be done to make it all read properly? Right now I have a Stage II jet Chip but I will sell it if they make a hand held programmer that corrects the ECM when you use oversize tires if I need to.

Please give me some input, I really need to order a set before the week is up.

Thank You,
JCT
