Hummer H3X Tires — Fitment by Year
OE size on your 2008–2010 H3X is 265/65-18, and I keep those on the rack along with a few upgrade options depending on what you're after. 18-inch is the standard, but I've had folks come through wanting to go up to 20 or 22, and the bolt pattern's 6x139.7 with a 100.50mm hub bore—specs I verify on every install so nothing spins or sits wrong. Between the stock fitment and the aftermarket stuff, there's room to dial in what works for your truck.
For straight OE replacement, I stock the 265/65-18 in a couple of brands—Goodyear, Continental, Michelin—all load-rated for what the H3X needs. If you want to step up in sidewall or tread, I can fit 275s or 285s depending on your rim choice, and I'll make sure the overall diameter stays close enough that your speedometer doesn't drift. Load rating matters on these trucks; I don't cut corners there.
Once you pick your tire, my crew handles the full mount-and-balance in-house. I run road-force balance on every one—not just spin-balance—so you're not fighting vibration down the road. We check your TPMS, verify that hub bore, torque the lugs to spec, and I'm here to walk you through it in English or Spanish. Fifteen years in Marietta, and I've built this shop on doing the work right the first time, no shortcuts.
We mount these for folks across Marietta, Roswell, and East Cobb. If you need financing, Synchrony Car Care runs a 6-month promo on purchases over $199, and we also offer lease-to-own through Acima starting at $10 down. Walk in at 1585 Roswell Rd, call (678) 400-6467, or book online and we'll get you sorted.

What we double-check on Hummer H3X
- Staggered fitments (different front/rear sizes) are common — we'll confirm rotation direction and stagger before mounting.
- Wheel-bore-to-hub fit verified on every mount. UHP and summer compounds get checked for thermal date code so you're not buying old rubber.
- Track-prepped vehicles get torqued to spec twice — once at mount and once after a 25-mile heat cycle.
Common questions about Hummer H3X tires
What's the OE tire size on a 2008–2010 Hummer H3X?
Stock size is 265/65-18. That's what I keep in rotation, and it's the right fit for your truck's 6x139.7 bolt pattern and 100.50mm hub bore. If you want to go up in size—275 or 285—I can make that work, but we'll keep the overall diameter in the ballpark so your speedometer stays honest.
Do you install tires same-day?
Yeah, walk-ins are welcome. If we're not swamped, I can get you mounted and balanced the same day. Call ahead at (678) 400-6467 if you want to make sure my crew's got the time blocked out, especially on a Saturday.
Can I finance tires for my H3X?
Two options. Synchrony Car Care gives you six months interest-free on orders over $199. Or if you want lease-to-own, Acima starts at $10 down. Either way, we handle it right here at the shop—no call center, no hassle.
Will a bigger tire fit my H3X?
Depends on your rim. If you're on an 18-inch, you've got room to go up to 275 or 285 without rubbing. I'll check your specific setup before we order so there's no surprises. The key is keeping the overall diameter close to OE—that's why I measure everything.

Family-owned · Marietta · Since 2010
Built and run by Max Caba and a small team of techs.
We don't outsource installs and we don't sell tires we wouldn't put on our own trucks. Every wheel goes on with a torque wrench and a road-force balance, every TPMS sensor gets reset before you drive off, and every fitment question gets answered by someone who'll be here next week when you call back.
Fifteen years of doing it the same way — that's the whole pitch. We're a small shop on Roswell Road, not a chain, not a call center. Walk in and you'll meet the same techs who'll touch your truck.
