Mercedes-Benz C450 Tires — Fitment by Year
The 2016 Mercedes-Benz C450 rolls on either 225/45-18, 245/40-18, 225/40-19, or 255/35-19 depending on trim — I keep all four sizes on the rack because we get these in regular. Bolt pattern is 5x112, hub bore sits at 66.56mm, and you're looking at 18 or 19-inch rims depending on what came from the factory. I had a '16 come in last month with the 245/40-18 setup, and we nailed the fitment first call.
For straight OE replacement, I stock load-rated equivalents across all four sizes — nothing gets installed in my shop without matching or exceeding the original spec. If you want to step up to a performance tire or something with a bit more grip for Cobb County daily driving, I've got options that keep you in the same diameter and load range. The difference between a 225/45-18 and a 245/40-18 is real — it changes your speedometer reading and ride height — so I always confirm which size is on your door jamb before we talk upgrades.
Once you pick the tire, my crew runs the full protocol: TPMS sensor check and programming, hub-bore confirmation so the wheel sits flush, road-force balance on every one, and torque sequence by the book. We're bilingual here, walk-ins are welcome, and I've been in Marietta fifteen years doing this the same way — in-house, no outsourcing. You'll see the same faces every time.
We mount these for folks across Marietta, East Cobb, and Roswell. If you need financing, we run Synchrony six-month promo on orders $199 and up, or Acima lease-to-own starting at $10. Walk in at 1585 Roswell Rd, call me at (678) 400-6467, 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 Mercedes-Benz C450
- 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 C450 tires
What's the OE tire size on a 2016 Mercedes-Benz C450?
Depends on trim. Most come with either 225/45-18, 245/40-18, 225/40-19, or 255/35-19. Check your door jamb or the sidewall of what you've got now — that's your baseline. I always confirm before we order.
Can I fit a different tire size on my C450?
You can stay within the OE diameter range — 18 to 19 inches — and match the load rating. Going from a 245/40-18 to a 225/45-18, for example, keeps you in spec. I won't install something that changes your speedometer or compromises safety.
Do you install tires same-day?
Yes. I run TPMS programming, road-force balance, and torque sequence on every install. If you come in before 4 p.m. on a weekday, you usually drive out the same day. Walk-ins are fine.
Can I finance tires at Road Runner?
We offer Synchrony six-month promo on orders $199 and up, or Acima lease-to-own starting at $10. Both are quick — you'll know in minutes.

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.
