Tires OEM BMW or Kumho

Go with the Kumhos from Tire Rack. I had really good experience with them

I've used Sumitomo and Kumhos performance summer tires with success - although the Kumho PA31's I put on the Fit have worn super fast and are now quite loud.

Wrapped in Kumho Ecsta V720 tires, have less than 5000 miles on them

Kumho AT51 have been really good. Really quiet, great in winter, but feels like you driving on ice at high speeds (80mph) which is expected from these tires.

I would go for the kumho tires out of those 3, they make some decent tires.

Go with the Khumo. They’re a reputable brand. I’ve heard of some people having issues with the warranty. My personal first hand; they were a great performing tire. I rode mine hard though. So they only lasted about a year and half. It was the MT.

Kumho is a well known brand compared to the rest. I'd do kumho solus before any of them.

Since last time you saw it I upgraded the brakes to 312mm rotors with ATE 57 calipers in front and 256mm disk brakes in the rear and replaced the heavy Mercedes replica 18" wheels with BBS RK's in 8J 17 wrapped in sticky kumho KU-36 rubber.

I have the Kuhmo Road Venture APT KL51 235/60. I was very happy with them until I realized the fronts are shot after 20K mi. I probably ran them under inflated a bit for too long. And never rotated them =(. The taller than stock size makes zero noticeable difference on the speedo or power on the road. My speedo matches my GPS reading exactly. Clearance is no problem.

I bought these exact tires for my gli. I don't know what the deal is with them, but they flat out SUCK in the snow. The are by far the worst performing all season tire in terms of snow usage that I've ever run.
