Great Tires
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

Great tyres, conveniently & quickly delivered!
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

and they where pretty smooth. Offroad traction on trails has been great ...
Arrived quickly. Tried them out with NO balancing on them just out of curiosity, and they where pretty smooth. Offroad traction on trails has been great and these have taken the mildly modded Samurai to yet another level of improved capability. Previous tires were 10+ year old BFG AT with only 30% or so tread left and to be fair, I got them 2nd hand and didn't get to experience them new. So, probably any half way decent tire would have been noticeably better than old dried out tires, not matter how good they may have been when new. That being said, the Samurai nearly doubled it's abilities with it's 3" lift and move up to 31's... then adding a rear locker and proper diff gearing netted almost as big a gain again. Finally, adding these tires was not quite as big a jump as the other mods... but, again, a VERY noticeable gain in offroad traction and climbing ability. Long, 100% grade climbs that used to take effort and both hands and were a bit of a challenge, suddenly became casual, one hand on the wheel affairs. No chance to try them in in rain or snow yet.... but trail and rocky stuff has been great. Watch the "cooper puncture test" video online. As for noise.... my 4x4 is NOT my daily driver... so "tire noise" is more like TIRE MUSIC to me. But they are not particularly loud. Yes, you can hear them and they are more noise than your street car.... but, by FAR are NOT that noisy for mud tires. Prices on these fluctuate FAR more than BFG KM2 (my other choice).... but the BFG's would NEVER drop as low priced as these have from time to time.... When they dropped to only about $25 more than the cheapest tires out there, it was a no brainer! VERY pleased with them! [O.|||||.O]
