Mercedes Tire Calculator
Your source for Mercedes-Benz tire sizing, upgrades, and compatibility information.
Mercedes-Benz vehicles combine luxury and performance, and tires are key to both. This hub offers tools to compare tire sizes (including MO/MOE - Mercedes Original/Extended run-flat considerations), analyze Staggered Fitments common on AMG and RWD models, check Wheel Offset & Clearance for custom wheels, explore Plus Sizing, and get AI Tire Advice tailored to your Mercedes model and driving style. Includes tips for Mercedes tire selection focusing on comfort, performance, and OEM recommendations.
Essential Tools for Mercedes-Benz Owners
Important Tips for Mercedes-Benz Owners:
- MO/MOE Tires: Check your vehicle's doorjamb or manual for MO (Mercedes Original) or MOE (Mercedes Original Extended run-flat) specifications. These tires are specifically tuned for your vehicle.
- Performance vs. Comfort: For AMG models, tire choices greatly impact performance. For non-AMG models, touring or grand-touring tires often best match the vehicle's emphasis on a quiet, comfortable ride.
- 4MATIC AWD: For all-wheel-drive models, ensuring all four tires have closely matched diameters is important to prevent drivetrain strain.

Stock tire sizes for the most searched Mercedes-Benz models. Many Mercedes use staggered fitments (different front/rear sizes) and MO/MOE run-flat designations — verify both before purchasing replacements.
| Model | Year | Stock Tire Size | OD |
|---|---|---|---|
| C 300 (staggered) | 2022–2025 | 225/45R18 (f) / 245/40R18 (r) | 26.0" / 25.7" |
| E 350 / E 450 | 2021–2025 | 245/45R18 | 26.7" |
| GLC 300 | 2023–2025 | 235/55R19 / 255/45R20 (AMG Line) | 29.2" / 29.0" |
| GLE 350 | 2020–2025 | 265/50R19 | 29.4" |
| C 63 AMG (staggered) | 2022–2025 | 255/35R19 (f) / 285/30R19 (r) | 26.0" / 25.7" |
MO = Mercedes Original (run-flat approved). MOE = Mercedes Original Extended (run-flat with extended mobility). Staggered setups cannot be rotated front-to-rear.
C 300 — Dropping run-flats for a better ride
Many C 300 owners replace OEM MO run-flats (which add ~15 lbs per corner and produce a harsh ride) with non-run-flat performance tires. Keep the OEM size (225/45R18 front / 245/40R18 rear) and add a portable inflator kit or space-saver spare. Note: some Mercedes leases or CPO warranties require MO tires — verify before switching.
GLC 300 — Upgrading to AMG Line size
Upgrading from base 235/55R19 (29.2" OD) to the AMG Line 255/45R20 (29.0" OD) gives a wider, lower-profile stance. The OD is nearly identical (−0.2", −0.7% speedo) so fitment is straightforward. Confirm your wheel well has clearance for the extra width before purchasing.
AMG models — Choosing the right performance tire
Staggered AMG setups cannot be rotated — tire wear is uneven and replacements are often in pairs or sets. Focus on premium compound choice: Michelin Pilot Sport 4S (OE fitment on many AMG models), Pirelli P Zero (also OE on some), or Continental SportContact 7 for track use. Always match the MO approval marking if required.
