Tires NITTO or Cooper

I switched to 295/30 on 18x11 rt660s and the car was completely different. Very responsive and very good turn in.

I put these tires on my 2019 gmc sierra at4. I noticed a huge improvement towing with stability. The was no squirm in the back end and the truck felt much more planted on the road.

The downside of these tires are that they are stiff which actually effects your suspension tuning. You may notice the tires lose contact with the road momentarily at times over bumps.

All these responses saying the NT555 G2s suck worry me... cause I just bought a new set for my 2004 GT. And I love them so far...

I bought the same tires, 275/65r20 - been great all winter here in Alberta

Great tires, I have great luck with Cooper!

Got the same in stock tire size. I really like them. I think they're good tires and they've been wearing well on my mixed highway and city driving with occasional towing.

Another vote for NT01’s, I beat the piss out of them to the cords. Some of the fastest laps me and a couple buddies have are a session before they cord.

Not sure what size you are planning or what platform, but I'll give you Nitto feedback FWIW.

17' cummins 35-12.50-18's .It will pick up rocks and throw them a lot. Maybe have 20-25k and are less than half tread.

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.

My ridge grapplers slide in the rain more than any tire I’ve had. I’ll go to turn and I won’t even be going fast and I’ll just keep sliding the way I was going.
