Continental EcoContact 6 255/45 R20 Maserati Grecale 20,000 miles October 24, 2026

Solid grip when dry, OK comfort, however, very significant drawback of this tyre is mileage - barely lasted me 20,000 km, very soft sidewall with multiple bulges at the end of life, very shallow tread at start (about 6mm) and very soft - reached about 3mm in 19,000 km. Very bad tire, do NOT recommend to anyone.

Bridgestone Potenza Sport AS 255/45 R20 Audi SQ5 15,000 miles October 17, 2026

A very satisfying tire in most regards, though comfort is mediocre.

Michelin CrossClimate SUV 255/45 R20 Audi Q5 16,000 miles October 17, 2026

Loved the tires at first. At 15,000 miles the tread cupped and were very loud. I replaced the tires under warranty with a different tire.

Bridgestone Ecopia EP422 plus 255/45 R20 Mitsubishi Outlander 28,000 miles September 24, 2026

I drive conservatively but still found these tyres reach their limit easily. Especially when worn, they would squeal during tight turns, even when going slowly like in a car park.
They were quite comfortable but became very loud as they wore down especially above 80km/h.
My set were OE for my PHEV Outlander and were worn to .5mm of the indicator within 45,000km/28,000mi. I could maybe have babied them to 50,000km with a rotation around 30,000km.
These are not off road oriented tyres, but I drive on dirt roads multiple times a week. They gave good confidence when new, but became slippery on dirt roads as they began to wear.
It may be due to the low profile of my tyres (255/45/20) but I damaged 3 wheels from potholes in their short life.
Overall I was quite disappointed in these tyres, they were quite decent early on, but wore out quickly and became increasing bad in multiple ways as they wore down. I was excited to replace them and would recommend replacement with something else if your vehicle comes with these, even if you haven’t reached the tread wear marker yet.

I feel very bump on the road, always need keeping driwing wheel. These tyres are for perfect road.

Falken Azenis FK520 255/45 R20 Alfa Romeo Stelvio 2,0 280 hp 7,000 miles July 20, 2026

Nothing to complain except the groove cracks after just 10.000 Km and almost 2 years, with the correct pressure and storage temperatures during the winter. Really dissapointed.

81%
Pirelli Scorpion Elect 255/45 R20 Skoda Enyaq 80 31,000 miles July 10, 2026
Good average tires, not for sports driving, but they did a grat job on my wife's Skoda Enyaq. good comfort and noise levels.
