Tires Continental or Kumho

I put some Kumho Crugen on my grandmas van and they were great. She did a few trips from LA to Sacramento(7 hr). No issues.

I've got Continental Viking Contact 7's on my AWD M3 and they're also fantastic.

I currently have Continental CrossContact XL 20 in. tires on my 2020 Buick Enclave. These are OEM tires that I was skeptical of since I usually prefer Michelin tires. These Continental tires are rated at 60K miles but currently have 63,000 miles on them and don't need to be replaced yet. They are quiet and grip well.

I haven't tried the Vittoria N.EXT, but I've ridden the GP5000 tubeless since they released around 6 years ago. My wife has been on the inner tube version. Great tyre, amazing grip, even in the wet, and very fast. I've also never had a flat. The only thing is they don't last super long - I reckon about 3-5000 km depending on your weight.

I don't know about these inparticular but I drove AT51 Kuhmos back when I had a 07 Liberty in Syracuse, NY.

I hiked and camped regularly with friends as well. Drove on trails, did moderate off-roading, heavy snow, ice, heavy rain, on top of it being my daily driver, so plenty of highway miles as well.

They lasted me 55K (rotated 4 times during ownership)

Never had a flat, great traction, great price.

One of the best tires I've owned. I had to emergency brake on a rainy day and man... my car was like glued to the road, no slipping, and stopped immediately. Their grip is amazing. On the durability side it is great too.

Hankook Ventus S1 evo3. Will not feel bad about using them for autox or track. As I picked up the cars after snow hit the ground, I took delivery with Conti VikingContact 7, which are pretty quiet.

Continental (CC series) Best mid range tyre. Very quiet. Still using it for 1 month, so far so good.

I find Kumhos Start going really hard as soon as the first few mm come off. Great for longevity but not great for ride and grip after first year.

Just this morning I changed out the Conti TX's for Conti DWS06's. Not something I wanted to do just after buying a brand new car, but already had a bubble on one tire. Didn't feel comfortable just replacing it. I replaced all 5, including the spare.
