Mercedes-Benz SL55 Tires — Fitment by Year
The 2003–2004 Mercedes-Benz SL55 rolls on a 255/40-18 front and 285/35-18 rear from the factory, sitting on a 5x112 bolt pattern with a 66.56mm hub bore. I keep both of those sizes in stock most of the time, and I've had a couple of these cars come through over the years—they're solid machines. The fitment's straightforward, but you want tires that handle that power setup right.
For OE replacement, I stock Michelin and Continental in those exact specs. If you're looking to upgrade, I can fit you with something that'll give you better grip without changing the diameter—maybe a Pirelli or Goodyear in the same 18-inch and 19-inch range. Load rating matters on a platform like this, so I always confirm you're getting Y-rated or better. The 285/35-18 rear especially needs that durability.
When we mount and balance, I run road-force on every one of them. That means I'm catching any high spots on the wheel or tire before you drive off. I'll also check your TPMS sensors, verify the hub bore sits clean, and torque everything to spec. We're bilingual here, and I do all the install work in-house with my crew—no outsourcing. Been in Marietta fifteen years, and that's how we've kept things tight.
We mount these for folks around Marietta, East Cobb, and Roswell. If you need financing, I've got Synchrony for six months promo on orders $199 and up, or Acima if you want to lease-to-own starting at $10. Walk in anytime, call me at 678-400-6467, or book online below.

What we double-check on Mercedes-Benz SL55
- OE wheels are hub-centric and TPMS-equipped — we reseat sensors and verify hub-bore fit before torque.
- Several model years originally came with run-flat (RFT) tires. We'll confirm whether your spec sheet calls for RFT or whether a standard radial is a safe swap.
- Tight wheel-well clearance on lowered or M-package trims — we check rub on full lock and full compression before you leave.
Common questions about Mercedes-Benz SL55 tires
What's the OE tire size on a 2003–2004 Mercedes-Benz SL55?
Factory spec is 255/40-18 front and 285/35-18 rear. Both are common sizes, and I keep them on hand. If you're running a different size and want to confirm fitment, call me and I'll verify it against your door jamb spec.
Do you install tires same-day?
Yeah, most of the time. I've got my crew here in the shop doing the work, so we don't have a long wait. Bring it in, and unless I'm backed up, you're rolling out in an hour or two with mount, balance, and torque sequence done right.
Can I finance tires at Road Runner?
Absolutely. Synchrony Car Care gives you six months promo on purchases $199 and up. Acima is another option if you want to lease-to-own starting at $10. Both are quick to set up.
What's the bolt pattern and hub bore for the SL55?
5x112 bolt pattern, 66.56mm hub bore. I've got that dialed in, and I'll confirm everything centers clean when you come in.

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.
