Tires Nexen or Kumho

I switched my '25 Turbo to the Kumho Crugen HP71's and am very happy with the increased sound insulation and performance. Much better in rain than the Toyos I had (which developed a giant bump on the side wall 3k miles in).

This is new release from Kumho, so reviews were sparse with the exception of one from Germany. I have about 500 mi on the tires, they are awesome! I can get traction now WOT in 1st, they have a stiffer sidewall which makes them responsive and planted in corners. Further, the ride is quiet and smooth which is important to me for a DD.

I've had the previous Kumho Ecsta Sport on a different car for budgetary reasons. They were great for a few months, but I felt like they lost a ton of grip after 10k miles or so. Longevity was my only complaint, but it was for my daily so even without a ton of grip, I'd consider them a good buy for value.

I get a lot of kms out of kumho solus

You can look into Nexen. Korean brand. Not as cheap as the Chinese brands but not as expensive as the known brands. I fitted these on my Tiguan last year. Take my anecdotal experience with a grain of salt, but the ride felt quieter with the Nexens vs the Bridgestones it had on before.

If you have the 15" stock wheels, check out nexen npriz AH5. I got some off Amazon for my 65 riviera when I was stock height.

Overall happy with my Kumho Roadventure AT51 on my F150. Not the best on pure ice, but only real complaint on the F150 is they don’t seem to last as long as I’d like, but I run them all year and I’ll get equivalent of about 30,000mi out of a set, heavy truck, all year, towing, winter, mud, highway, you name it - and a lot of roundabouts in my neck of the woods which is apparently known to be hard on them… from chatting with buddies I get about 90% of the kms they get on a set of BFG KO2, but they cost about 20-30% less typically, and are quieter, and seem roughly equal capability otherwise.

I replaced mine after 27k miles and they were DONE, no thread left on any of them. 13k miles later they look very good, but I have also been rotating them (unlike the Kumho ones).

730s are pretty disappointing as an autocross tire. They thrive on heat, but it’s hard to get them hot enough that they will work well for autox. They are awful in cold weather.

My '23 Versa came with Npriz S and it's labeled as "bad" by the dealership at 23k miles and now at 30k they aren't looking good at all to me. One just started a slow leak.
