Tires Kumho or MRF

I’ve ran Ecstas on all my cars they’re good tires

After blowing out a tire on a particularly nasty pothole I replaced my stockers with a set of Kumho Ecsta PA51 XLs. These are a nice, reasonably priced set of ultra-high performance all seasons that I'd been running on my MR2 Turbo and been very happy with.

Mine are 7 years old and the best tires shop in my town said that I still have 10-12k miles left on them. I decided to replace with the exact same ones though, since my car sits in FL sun whole days. They are excellent.

Our OEM Kumho Crugens are around 4/32” at 54,000 miles. We have found them to be just fine, quiet and smooth with no punctures or other incidents.

We have a 2023 AWD Pro S with the same tires. We just replaced at 30k. They probably could have gone another 5k or so, but one tire had a slow leak and they wouldn’t even try to repair it due to age of the tire. We got the same tires again at Discount/Americas Tire because they seemed fine

V730, Conti ECF, hankook RS4 is the way to go for endurance 200 and or less $$ per lap

Installed some AT tires and new wheels. After 1000 miles my efficiency dropped from 2.4 to 2.1 based on my driving habits and daily commute.

the kumho tires ours came with from the factory lasted to around 50-55,000 miles. I’m disappointed I was stupid enough to not rotate them, and paid the price because oddly, front tires were perfect. Both rear tires are absolutely blasted after around 45,000 miles give or take. Severe cupping to the point I swear both tires had bad belts.

My experience with Kumho was once the top layer of the tire wore off (e.g. after a year), performance of the tire degraded. They must use a cheaper rubber underneath.
