Pontiac G3 Tires — Fitment by Year
The 2009 Pontiac G3 rolls on either 185/60-14 or 185/55-16 depending on trim, both sitting on a 4x100 bolt pattern with a 56.60mm hub bore. I keep both sizes on the rack because we see these come in regularly, and the fitment matters — that 14-inch versus 16-inch swap changes how the car feels on the road, so I want you to know exactly what you're working with before you walk up to the counter.
We stock OE replacement rubber for the G3, and I also carry upgrade options if you want to step up in sidewall or grip without losing that tight 4x100 bolt spec. The load ratings on these are modest — this is a lightweight platform — so I don't push oversizing; what works is what works. If you're looking to refresh the look with a different diameter rim, I can help you dial in the right tire to keep your speedo honest and your suspension happy.
When your G3 comes in, my crew runs it on the road-force balancer, checks your TPMS sensors, verifies the hub bore sits flush, and torques everything to spec. We're bilingual in the shop, walk-ins are always welcome, and I've been doing this work in Marietta for fifteen years — I know what these cars need. You'll see the install happen in-house, not shipped off somewhere.
We mount tires for folks across Marietta and the surrounding areas. Financing through Synchrony works for purchases over $199, and if you need to spread the cost, Acima gets you rolling for ten bucks down. Call me at (678) 400-6467, walk in at 1585 Roswell Rd, or book online below.

Road-Force Balance
Every tire gets road-force balanced and the hub-bore matched to your wheel — no highway buzz, no return trips.
What we double-check on Pontiac G3
- 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 Pontiac G3 tires
What's the OE tire size on a 2009 Pontiac G3?
The G3 came in two fitments: 185/60-14 on the base trim and 185/55-16 on the higher trim. Both are 4x100 bolt pattern. I can confirm which one you've got when you come in or call, and I keep both sizes in stock.
Can I fit a different size tire on my G3?
Yeah, you've got some room to work with. The G3 uses a 4x100 pattern, so you're not locked into the OE diameter, but I don't recommend oversizing on this platform — the car's light and the suspension is tuned for that narrow sidewall. I'll walk you through what makes sense when you come by.
Do you install tires same-day?
Usually, yes. I run everything in-house with my crew, and we don't have a call center or backlog like the chains do. Call (678) 400-6467 in the morning and let me know what you need, and we'll get you in.
Can I finance tires for my Pontiac G3?
I offer Synchrony Car Care financing for purchases over $199 — six months promo — and Acima lease-to-own if you want to start with ten bucks down. Both work for tire-and-wheel packages.

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.
