At-a-glance fitment comparison
The table is filtered to researched tyre sizes: 225/50 R17, 225/45 R18, 245/40 R18, 225/40 R19, 255/35 R19. Compare the listed size against the current tyre sidewall first, then check load/speed rating, season and run-flat notes. Products outside those researched sizes are deliberately excluded from this vehicle shortlist.

What the fitment research shows for the 2017 Mercedes-Benz C-Class
The clearest takeaway is to treat this as an exact-fit shortlist, not a model-year blanket recommendation. The researched sizes for the 2017 Mercedes-Benz C-Class are 225/50 R17, 225/45 R18, 245/40 R18, 225/40 R19 and 255/35 R19, and some wheel packages use staggered front and rear sizes. That means the front and rear tyres may not match on every car, so confirm the current sidewall and vehicle placard before ordering. This shortlist is intentionally cautious and only includes matching Tyres.net summer tyres from Pirelli and Continental.
How to compare matching tyres on this shortlist
Because the visible price spread is narrow, value is less about chasing the cheapest number and more about choosing the right match for your wheel package and driving style. The shortlist includes Pirelli Cinturato P7 (P7C2) 225/45 R18 95Y Summer, Continental ContiPremiumContact 2 225/50 R17 98V Summer, Continental EcoContact 6 225/45 R18 95Y Summer and Continental ContiSportContact 5 P 255/35 ZR19 96Y Summer. Compare exact size first, then season, brand familiarity, current stock and delivery, and the kind of driving you do most often, whether that is commuting, motorway miles or a more sporting setup. If stock or delivery differs between matching sizes, that can be a practical tie-breaker once fitment is confirmed.
How to choose the right tyre for your car
Start with the tyre sidewall on the car, then confirm the vehicle placard or handbook before you click buy. If your 2017 Mercedes-Benz C-Class has a staggered setup, check front and rear sizes separately, because one tyre size will not suit every axle on every trim. After the size match is confirmed, compare the load index, speed rating, season, run-flat marking if relevant, and the latest stock and delivery details on the retailer page. If the listing and the car disagree, stop and have a tyre specialist confirm the fitment before ordering.
Why 2017 Mercedes-Benz C-Class tyre sizes vary
This model year can wear several different wheel and tyre combinations depending on trim, wheel option, market and any changes made by a previous owner. That is why this page only uses the researched sizes 225/50 R17, 225/45 R18, 245/40 R18, 225/40 R19 and 255/35 R19, rather than assuming one universal fitment. If the size on the sidewall does not match the size on the placard or retailer listing, stop and have a tyre specialist confirm the correct fitment before ordering.
Load index, speed rating and run-flat checks
A matching rim size is only part of the decision. The listing should show a load index and speed rating that you can compare with the current tyre, and you should also check whether the car currently uses run-flat tyres before choosing a replacement. If your existing tyre and the placard disagree, the safest route is to verify the fitment with a qualified fitter rather than relying on a close-looking size.
Choosing a season for this shortlist
Every tyre in this shortlist is a summer tyre, so the options here are most relevant if you are replacing summer fitments rather than moving to an all-season or winter setup. Within that summer-only group, the comparison is mainly about use case: Pirelli Cinturato P7 (P7C2) leans toward comfort and mileage, Continental EcoContact 6 is more efficiency-leaning, Continental ContiPremiumContact 2 places more emphasis on braking and handling security, and the ContiSportContact lines suit shoppers who want a more sporting feel. Check the latest price, stock and delivery on the retailer page, because availability can matter more than a small price difference.
Value is about fitment first, not the lowest price
The visible price range is relatively tight, so the better value choice is the tyre that matches your exact size, axle setup and driving needs without forcing a compromise. For example, the 225/45 R18 and 225/50 R17 options sit close together in price, while the 255/35 ZR19 sport-focused tyre sits higher in the spread and may suit a different wheel package altogether. Price, stock and delivery are secondary to fitment: check the latest retailer price and availability before ordering, then weigh brand familiarity and whether the listing shows the load and speed details you need.

Buying questions
Can the same 2017 Mercedes-Benz C-Class use different tyre sizes?
Yes. Trim, wheel option, market and even previous wheel changes can alter the correct size, which is why this guide lists only the researched fitments. Confirm the current sidewall and vehicle placard before ordering, and check front and rear tyres separately if your car has a staggered setup.
Where do I find the exact tyre size on my car?
Check the tyre sidewall first, then use the vehicle placard or handbook as the final reference. You should match the width, profile and rim size shown on the car, and also compare the load index and speed rating with the retailer listing before you buy.
Are these tyres suitable for summer use only?
Yes, the shortlist shown here is summer-only, so it suits drivers replacing summer tyres rather than shoppers looking for all-season or winter alternatives. If you want year-round flexibility or colder-weather traction, compare a different seasonal category instead of relying on this shortlist.
How should I compare price, stock and delivery on matching tyres?
Once the size is confirmed, use price, stock and delivery as practical tie-breakers between matching options. A tyre that is slightly dearer but available sooner may be more useful than a cheaper listing with slower delivery, especially if your car needs a staggered pair in a specific size.
Should I match load index, speed rating and run-flat status exactly?
Compare the listing details with the tyre already fitted and the vehicle placard before you order. If the load index, speed rating or run-flat status is unclear, or if the sidewall and placard do not agree, ask a qualified fitter to confirm the correct replacement rather than guessing.
