Tire Question

[dbal44]

New 2006 Hummer 3 owner I am this looking to replace tires with Nitto Trail Grappler tires with 20 inch Rockstar rims. Question if I go with these tires: 275/65 R 20 (34.33 overall diameter) (10.98 overall width) will they fit on H3 with no raise or leveling modifications. I am happy with current stance and looking to avoid tires rubbing. Also forums talk about offset and back spacing, not sure what to go with here.

Looking to purchase tires and rims soon so any info would be helpful. Thank you.

You might want to go with 5" backspacing. I doubt you would have to raise anything but you could always raise the front a little if you experience any rubbing.

Why don't you wanna crank the torsion bars up a little bit? You can do this without buying a single part. Measure from the center of your centercap (the H in hummer) up to the bottom of the fender. Don't exceed 23.5" and you'll be ok. Those tires will fit just fine. You'll need an alignment after you crank up the t-bars but that wouldn't be a bad idea anyway since you're putting new rims and tires on.

Most rubbin of the tires comes from crankin your wheels all the way left or right. I have 35s, 315s, they do rub on if I crank the wheels all the way. All I do is back off alittle and everythin is good. It only rubs on the sway bar also...Good luck
