Here is something that I posted a couple of months ago on the subject of tires:
I'm getting ready to put on my 5th rear tire on my 2014 and, while I got 20,000 miles on a Kumho, I will most likely not put another one on. I find that the Kumho hydroplanes too much for my liking.
Here is what I have had on my RT
Kenda rear 9,600 miles (it was ready to be changed at 7,500 miles)
Arachnid rear 8,300 miles (it was ready at 7,500 but I could have gone to 10,000 on it)
Kumho rear 20,714 miles
Arachnid rear 8,971 miles (it is ready to go now)
Front:
Kenda 17,955 miles
Federal Evo 29,630 miles - Wow, I didn't realize that I had so many miles on them. But they are ready.
Update: I put on the Yokohama S Drive and a new set of Federal Evo's on the front before my trip to Alaska. With nearly 9,000 miles on the tires the rear Yokohama is about done and the Federal's are looking like they will go 30,000 miles. What to try next..................
