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
The 2019 Mercedes-Benz C-Class does not use one single tyre size across every trim or wheel package, so this page is built around exact researched matches: 225/50 R17, 225/45 R18, 245/40 R18, 225/40 R19 and 255/35 R19. Some wheel setups can be staggered front to rear, which means each axle may need its own check before you buy. The shortlist is deliberately size-led, with summer tyres from Continental and Pirelli, so the useful next step is always to confirm the current sidewall or vehicle placard and then compare season, load index, speed rating and price.
How to compare the matching tyres
Once the size is confirmed, the most useful comparison is not just price but the intended use case. EcoContact 6 is positioned as an efficiency-led Continental choice, while ContiSportContact 5 and ContiSportContact 5 P lean more toward sporty handling, and Cinturato P7 (P7C2) sits in the summer high-performance middle ground with wet-performance and mileage emphasis. The price spread in the shortlist is narrow at roughly £123.68-£129.20, so the better decision usually comes from exact size fitment, brand preference, stock and delivery rather than chasing the cheapest listing alone.
How to choose the right tyre for this car
Start with the tyre sidewall on the car, then check the door placard or handbook if the current tyres have been changed previously. After size, compare the load index and speed rating on the live retailer page with the rating on your current tyre, and check whether the car currently runs on run-flat tyres before swapping specification. Because some 2019 Mercedes-Benz C-Class wheel packages are staggered, front and rear sizes should be checked separately rather than assumed to match.
Why the same 2019 C-Class can need different sizes
A 2019 Mercedes-Benz C-Class can wear different tyre sizes depending on trim, wheel diameter, market and whether a previous owner changed the wheels. That is why the researched sizes are listed individually instead of being rolled into one model-wide recommendation. A 225/50 R17 fitment is not interchangeable with a 255/35 R19 fitment, and a staggered package may use different front and rear sizes, so the current sidewall is the safest reference point before ordering.
Specification checks that matter before buying
The fitted tyre size is only the starting point for a proper order. The live product page should be checked for load index, speed rating and any run-flat marking if that matters to your current setup, because the shortlist contains different rating combinations such as 91W, 95Y, 96Y and 98V across the matching sizes. The shortlist is summer-focused, so it is best viewed as a warm-weather road-use comparison rather than a winter or all-season buying guide.
How the shortlist differs by driving need
The shortlist is useful because it separates the tyre choices by the kind of driver they may suit. EcoContact 6 is the more efficiency-led option, ContiPremiumContact 2 sits as a balanced summer match for the 225/50 R17 size, and the ContiSportContact items are the more sporty-leaning options, especially the 255/35 R19 fitment. With no visible review scores in the available product information, the practical way to compare them is by size, summer use, price and whether the tyre is better aligned with commuting, motorway miles or a sharper-feeling setup.
Value, stock and delivery checks
The shortlist price range is narrow enough that value depends more on fitment and availability than on dramatic cost differences. EcoContact 6 is listed from £123.68-£191.82, ContiSportContact 5 from £124.12-£223.68, Cinturato P7 (P7C2) from £126.11-£168.83, ContiPremiumContact 2 from £128.84-£202.54 and ContiSportContact 5 P from £129.20-£279.73, so it pays to compare the exact size first and then check the retailer for the latest price, stock and delivery terms before committing.

Buying questions
How do I know which 2019 Mercedes-Benz C-Class tyre size I need?
Check the current tyre sidewall first, then confirm the vehicle placard or handbook. For this guide, the researched sizes are only 225/50 R17, 225/45 R18, 245/40 R18, 225/40 R19 and 255/35 R19, and trim or wheel changes can alter the correct one.
Why can two 2019 Mercedes-Benz C-Class cars use different tyre sizes?
Wheel size, trim level, market and previous wheel changes can all affect fitment. Some Mercedes-Benz C-Class wheel packages also use staggered front and rear sizes, so the front axle and rear axle should be checked separately rather than assuming one size fits the whole car.
Should I compare load index, speed rating and run-flat marking before buying?
Yes. Size alone is not enough, because the same nominal fitment can appear with different load and speed ratings. If your current tyres are run-flat, check the replacement listing for the same requirement before ordering, and always confirm the latest retailer price and availability.
