Mercury Grand Marquis Tires — Fitment by Year
Between 1992 and 2011, Mercury Grand Marquis rolled out with a 225/60-17 OE tire size on most model years, sitting on 17- to 18-inch rims with a 5x114.3 bolt pattern and 70.50mm hub bore. I've been mounting these since the early days—they come through the bay pretty steady, and I keep the common sizes on the rack so you're not waiting around. These are full-size cruisers, and the fitment window is pretty forgiving compared to some vehicles, but spec matters when you're running a 225 or moving up to a 235.
We stock OE replacements and a few upgrade options depending on what you're after. If you want to stay factory-spec, I've got that covered—same load rating, same ride you're used to. Some folks come in wanting a slightly wider tire for the road, and a 235/60-17 or 235/65-17 works clean on these frames without rubbing or throwing off your speedometer. Load index is something I always confirm because these are heavy cars, and I'm not putting anything on your Grand Marquis that doesn't handle the weight.
When we mount and balance, I run road-force on every one—not just spin-balance—so you feel the difference on the highway. TPMS sensors get checked, hub bore gets verified at 70.50, and I torque to spec in a star pattern every time. We're a family-owned shop fifteen years in Marietta, and my crew does every install in-house, no outsourcing. Bilingual service, walk-ins welcome.
We mount these for folks across Marietta, Roswell, Kennesaw, and the broader Atlanta area. If you want to spread the cost, Synchrony financing runs 6 months promo on purchases over $199, and Acima's lease-to-own starts at $10 down.

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 Mercury Grand Marquis
- 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 Mercury Grand Marquis tires
What's the OE tire size for a Mercury Grand Marquis?
Most Grand Marquis from 1992 through 2011 came with a 225/60-17. Some later models ran 235 or 245 widths, but 225/60-17 is the baseline I see most often. When you call or come in, I'll confirm your exact year and trim to make sure we get it right.
Will these tires fit my Grand Marquis?
If you've got a Grand Marquis between 1992 and 2011, yes. The bolt pattern is 5x114.3 across the board, hub bore is 70.50mm, and rim diameter runs 17 to 18 inches. I verify fitment in person or by phone—just tell me your year and current tire size.
Can I go to a wider tire on my Grand Marquis?
Absolutely. A 235/60-17 or 235/65-17 works without rubbing on these frames. Just make sure the load index matches or exceeds the OE spec—these are heavy cars. I'll spec it out so you're not stuck with something underbaked.
Do you install tires same-day?
Yeah, most of the time. We mount, balance with road-force, check TPMS, and torque everything in-house. If you come in early in the day or call ahead, I can usually get you rolling same-day. Walk-ins are always welcome.

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.

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.
