Label values come from the EU EPREL database and apply to the EU market versions of each tire. Wet grip and rolling resistance run from class A (best) to E; noise is the measured drive-by figure. A good label is a floor, not a verdict - the tests and owner ratings above tell you far more.

How long do 255/40 R18 tires last?

Michelin CrossClimate 3 Sport 255/40 R18 Mercedes Benz E350 Estate 16,437 miles August 17, 2026

Beautiful tire to drive on, felt smooth, responsive and very comfortable while be capable when required and offering excellent confidence through winter in the low temps and wet roads. Sadly while spirited driving was rare, the have lasted very poorly on my E350d - full alignment carried out before installing them, they lasted 16,437 miles and I have cords showing on both nearside inner edges despite the rest of the tread having up to 4mm, alignment was done in November 25 and July 26, all correct, tires fitted Dec 25, August 26 ruined.

Goodyear Eagle F1 SuperSport 255/40 R18 BMW 330i 12,500 miles February 7, 2026
Dry Handling and Cornering is amazing. Inspires confidence. Fares well in the wet for UUHP tire. Wear is fast on extreme torque usage. Well worth it though!

Continental MaxContact MC7 255/40 R18 BMW 330i 13,000 miles February 7, 2026
Conti MC7 is excellent in wet conditions. In dry conditions, it is very good although it would not be on par with UUHP tires like GY Eagle F1 Supersport. Definitely an upgrade from Michelin Pilot Sport 4 ZP which were the OE tires. Treadwear life is amazing.

Westlake ZuperAce Z-007 255/40 R18 BMW 420d 20,000 miles December 21, 2025
I’ve always fitted Bridgestone and this is the first time trying Westlake ZuperAce z-007. I can hardly tell the difference in any way except the price. I plan to fit Westlake now every time I want new tires.

Continental PremiumContact 7 255/40 R18 BMW 330D Touring 15,000 miles November 29, 2025
After 20.000kms the rears are around 4mm tread depth while the fronts are around 6mm, my g21 330d is quite torquey and heavy car so i didnt expect too much in terms of wear, but i still expected atleast 40.000kms considering i dont really push the car too much, i will maybe get another 10-15k on them and overall the tires have been ok, wet grip and stability has been really impressive, altho the tires were used in the summer mostly, a bit dissapointed with the noise considering how soft the sidewalls are, previous tires were bridgestone turanza t6 and those were extremely quiet.
Overall im slightly dissapointed in wear and noise considering these are really expensive premium brand tires that are more touring biased.
Will definately opt for similar tire next time just something that has better noise and wear.

Kumho WinterCraft WP72 255/40 R18 Mercedes Benz C300 300 miles November 25, 2025
Tires have been on a fortnight and 300 mmiles, but car is undriveable at fast speeds and anything over 60mph feels odd and I wouldn't want to have to take evasive action at anything over 50mph, temperatures are under 5 degrees c so it isn't that but it feels like the tirewalls are jelly, they are however quiet and comfy. It hasn't snowed yet to test the snow grip.
