Bought a set of 4 for my 2019 Nissan Pathfinder. The delivery was quick. They are exceptional. They look great on my car, and the ride is smooth without a lot of road noise coming from the tires. The 65,000 mile warranty is a comfort of knowing I have bought a quality tire. Definitely recommend

Needed new tyres for my LR Defender110...bought some other ones (no names!) from another company! They arrived WRONG SIZE..& it took 3 weeks for them to admit & collect & return payment. Amazon does give you "peace of mind" in that direction - and the tyres are really excellent! A good mix between off-road and road use...shame they are NOT winter-rated! Two years on...(2020) tyres are all good, hard cornering on a wet road they'll slide - but predictably! Good in winter as well - though not EU winter-rated! Wear after 35000Km is very acceptable. Use off road is excellent, fantastic grip (shattered half-shaft actually!). Recommended buy especially if you do any off road/mud travelling

Poco rumorose per il tipo di gomma e sono spaziali

I always used to use Dick Cepek tires until I bought my first set of coopers 2 years back. Now I always use Coopers on all 3 of my trucks. The SST,s are not noisy and handle perfectly on my f250 super duty , I love them for all my driving needs. They look aggressively awesome 10/10
