Tires Kumho or Firestone

I have ran Firestone Winterforce and Firestone Winterforce 2 on my RWD R/T Chargers since 2009 and have zero complaints.

Kumho Tires for everyone!!!!!

I went with Firestone destination at/2 in 235/65 r17. They are great and light weight! Only 4lbs more than stock tires.

I have a set of Firestone Destination All terrains tires and i love them.

Example, I switched to Kumoho from GSC's on 93 Trans AM. Yes I gave up traction but I gained smoother ride, better wet road handling, and about 12000 more miles a set. which basically doubled what I was getting out of GSC's. No question a better tire. Kumoho was still not big yet but what they did make was really good.

Upgraded to pilot sport AS at 30k miles because the Kumhos were no longer gripping in the rain (even though there was plenty of tread left).

Mid tiers. Pas tout a fait au niveau des meilleurs, mais pas mauvais non plus. Pas pour moi, je suis trop exigent, mais si tu veux pas mettre plus, c'est pas honteux.

Fair warning they're sketchy in heavy rain and temps below 40 f

I wore out a set of Kumho Ecsta 712's on my Miata in about 7.5K miles. Of course I was sliding the rears using the throttle to steer around curves on Highway 9 in California.

Tires (Kumho Ecsta LX Platinum) were installed 6/25/2024 @ 151,xxx miles (with receipts). Manufactured date is May 2023. Currently, car has 165,xxx miles. As you can see, the two front (now rotated to rear) tires are bald! The other two tires have a normal amount of tread remaining however. I was running about 1° of camber front and rear, and explains why the inside is more worn, but doesn't explain the overall accelerated wear that occurred only on the fronts. I also have an alignment report showing only the front left Toe is out of spec (-0.39° measured vs. +/-0.08 spec).

In my opinion, this would fall under the warranty via excessive/premature tire wear, but of course I imagine any shop would fuss about the lack of rotation. To make matters worse, I purchased and installed these tires at Walmart, which I'm now learning isn't an authorized Kumho installer and Kumho's warranty form says they must be installed by an authorized installer. However, Walmart's own listing for the tires says it's covered by a 50k mile tread life warranty (see last photo).
