Michelin CrossClimate 2 225/45 R20 25,000 miles September 11, 2026

In the summer the car is equipped with Michelin Pilot Sport EV. I like these much better than the CC2. Although not noisy in the specs, the CC2 have a specific rumble that takes some of the fun of driving an EV away.

Winrun R330 225/45 R20 Tesla 8,000 miles August 11, 2026

I used micheiln tires before, and i saw tire review on youtube. someone recommed winrun for ev. Really cost effective one, cuz i donot have enough budget on tyres, the stores recommend it for me. The driving experience is surprisingly quiet on both urban roads and highways. The tyres include with slient spong that reduce the noise from driving. This brand for daily communt is high-perfomrance. smoothly on acceleration sterring and braking on city road. but on mountain road, tyre slip at high speed on sharp bends such as hairpin corners. it need to be improve!!! and drive slowly on mountain road!!!!
winrun also save fuel for driving, under 98kmh, only consump for 147wh/km
the prices are really competive, only priced at only about one‑fourth to one‑third of michelin tires.

Kumho Crugen HP71 225/45 R20 Kia Motors EV6 GT 20,000 miles October 28, 2025
Found handling very poor especially in the wet, compared to continental premium 6 that the car came with from the factory. They wore down about twice as fast as the contis, so we will be going back to conti tyres.

Continental ContiSportContact 5 SUV 225/45 R20 Audi Q5 TFSI e 14,000 miles August 29, 2025
Grip in dry and wet was acceptable if nothing special. The reason I wrote this review is to say that the wear has been appalling at 14000 miles before needing replacements on my Audi Q5 TFSI-e. These were fitted as OEM from new but I won't be putting any continentals back on it. I had a similar issue with the OEM continentals on my Audi Q2 which lasted about 13000 miles before needing new ones.

Continental CrossContact LX Sport 225/45 R20 Alfa Romeo Stelvio 2,0 280 hp 25 miles December 4, 2024
These tires are OEM on a 2021 Alfa Romeo Stelvio TI Sport AWD. I live in the Denver Metro area so snow and some ice are a consideration. I felt the traction was as good as could be expected for an all season tire under most snow conditions for a sports SUV. Dry road feel and handling was excellent. I rated it approximately 8 because a summer tire clearly would be preferable for non winter conditions . Only occasionally were the tires driven very aggressively and about half my mileage was in long distance 75 mile per hour travel. After 25,000 miles the tread depth is about 3/32. Recently in the first deep snow w. about four to six inches and slush on the roadways I found the traction to be not at all what was needed, naturally. I would like to improve on all the performance aspects of the tire but I may not be able to find, based upon the reviews I have read a true improvement for all categories. When there was plenty of tread life still in the tires I went through three winters and never had an objection to the tire traction in snow conditions even when deep. So the odds are good that I will buy this same tire to replace my worn set.

Michelin Pilot Sport EV 225/45 R20 BMW 218d Active Tourer 100 miles November 22, 2024
Like other reviewers mentioned, the tyres are disastrous in any wet conditions. Just went through a puddle and then my tyres would skid in straight line braking… unbelievable

I am a big fan of Michelin PSS tyres but this is just not up to par at all. Took delivery of my XPENG G6 OEM tyres for only 10 days and now I have to pay 15k to get a new set of tyres

The tyres are just unsafe stay away from them

Accelera PHI R 225/45 R20 Vauxhall Astra VXR 8,000 miles August 21, 2024
Excellent value for money. Dry they are good, wet they are awful.but they're a summer sports tire for 60 quid for 20 inch so can't expect the world but 100% worth the money
