I went with Cooper Discoverer AT3 4S tires on my’n as stock replacement and very happy with my choice so far.
My primary concern was handling of snow and wet slush on the highway and so far this winter they’ve done excellent. The tread design does have a lot small sipes/cuts that work great for just that. Did not notice any increase in noise from them either.
Put them on a 2018 4Runner and they ride way better and quieter than the Toyo Open Country they replaced. They look great and they handle well in dry and wet but haven’t had the chance to test snow and ice yet myself.
Cooper's aren't THAT much more and they're great tires. I got 67,000 out of the ones on my 2003 Subaru Forester XS (RIP) they were at the end of their life though.
Tested on a 2018 AMG GT R in Porsche Ring, Audru, Estonia. So far I'm liking the CRS more. Price is the same as Cup 2, but it's faster and doesn't seem to be worse on street.
We also have good experience with Nankang on smaller cars. I have not tried them on bigger cars yet. They are a bit more noisy than the Vitour tires, but the white stripe on them seems to hold up a little bit better. But there is still no problem keeping them white.
Went from stock Bridgestones to Cooper ATT. Seems to be quieter and defintely a better ride. Not sure why a lot of people prefer Bridgestones pero I find them stiffer even if inflated to just below recommended.
I switched to Cooper SST Pro and have consistently gotten 45K out of them, on my 3rd set.
I've had a great experience with Coopers in the past, but my last set of ATs only lasted 10K miles before they needed to be replaced.
Cooper weathermaster st2 was by far the worst winter tires I've ever ran. Cooper zeon rs3 was the worst summer/all season.
I bought coopers about 3 years ago for my Silverado 1500. I will be honest this isn't an apples to apples comparison, I bought 4 ply (first mistake) AT3 4s's. They are cracking between the tread blocks on all 4 tires. Cooper won't warranty them saying it's just cosmetic, but they are deep cracks that go all the way around the tires between tread blocks on the inside and outside. I don't use chemicals or tire shine, and they are always kept at the appropriate pressures. They also lose chunks of tread every time i take them on the gravel roads in the mountains. I'm not happy with them at all, so my recommendation is to go with the K03's.
