What drivers say about their 255/50 R20 tires
The most recent owner reviews fitted in this size, in their own words.
Just changed from the Pirelli p-zero e's that came with the car (Polestar 4). What a difference!
Very smooth and comfortable and much lower noise over rough tarmac. Have not tried on winter roads yet so can't comment but dry and wet performance, feel og comfort is very good!
After 50,000km about 30,000 miles I think) the original 7.25mm tread is down to an average 3.7mm, rotated each 15,000 service. It bad at all for a 2000kg AWD EV. They are getting pretty noisy, and no longer grip well at freezing point in the wet. No skids tho, just slight loss of front wheel traction on sealed mountain ski field roads. So I go slower!
I will swap to a more efficient tire next time, but these have been surprisingly good.
Expected life will be 75,000km which is about 50,000 of the 16th century unit of distance.
In wet conditions the rear side of the car seems to loose grip , especially in the roundabout, ice and snow conditions if I use 2x doesn’t have much grip , but if I use the 4x4 seems to go trough the snow and ice ok .
Not a very good tire for wet/ snow weather conditions. Especially if you have a rear wheel drive car .
I needed a set of summer tires so I've got these tires with used wheels for my e-tron 55 '22. I didn't know these tires before and it was a good surprise:
- very quiet, important on an electric car
- good grip on dry surface
- ok on melted snow
- good traction on wet, tend to understeer
- did some light tests on gravel, ok to good (quattro do a great job)
- very comfortable
Only issue I had was a side puncture from a rock on a very dirty road in Corsica. Otherwise, there are quite secure, I tried to push the +400hp from the e-tron on Corsica roads under high temperature and did not get any issue.
I think these tires could last around 50k kms on my e-tron.
Yesterday, I replaced the original Bridgestone A001 soundproof foam tires on my NIO ES6 with Pirelli tires, hoping to improve driving safety and ride comfort. These Pirelli tires cost 50% more than the Bridgestone ones, so I expected a corresponding upgrade in overall performance.
However, issues arose during installation. Both new tires showed road force values between 11 and 12, exceeding the safe standard range. After professional road force calibration, the values were optimized down to 4 and 5 respectively.
After repeated adjustments, I have driven around 200 kilometers so far. The most obvious downside is the prominent noise at high speeds. I checked the weather data and confirmed it was only a gentle breeze of level 2 that day, so the noise is not wind noise. Instead, the tire rolling noise is louder than that of Bridgestone tires, and its sound tone is highly similar to wind noise, which cannot be masked even by turning up the car stereo volume.
In terms of shock absorption, it outperforms Bridgestone tires with excellent vibration isolation when passing speed bumps. Since the total mileage is still low, I need more time to experience its full performance. I hope the driving experience will get better after the tire break-in period. Frankly speaking, the current noise performance is quite disappointing, which is inconsistent with its EU Class A noise reduction rating.

I expected a super quite, comfortable and fuel efficient tire. The tire is indeed quite and super fuel efficient. My average got fuel consumption got improved by 1,5km on a liter. The comfort however, on slik adphalt it is, But the imperfections are not filtered and my interior rattles more than my Bridgestone Winter tire. I’ve lowered the fuel pressure but it did not improve. I’m a bit puzzled why the road feedback is so hard on the little imperfections. Perhaps it is the hard compound focus on fuel saving.
Overall ok tire. These were the OEM fitment on my Q8 e-tron and were very quiet, comfortable, and efficient. Dry grip and feedback was above average for an all season tire but still not particularly sporty. I think where this tire is showing its age the most is cold wet and winter conditions. It doesn’t do well enough in these conditions to justify the dry and warm wet sacrifices over a more sporty all season (e.g. Eagle F1 All Season) or a two tire solution. Ok if you want to focus on efficiency and comfort or can get a good deal.
