These are EV specific tires and do include foam padding inside. After installation, I noticed an immediate improvement in road noise. What really impressed me was the improvement in road noise during city driving and driving over bumps specifically. The Kumhos were much quieter in both areas. The ride also felt immediately smoother and more refined over the Continentals. While the tires did also reduce road noise in highway driving, the difference was not as stark as the former mentioned scenarios. I think the explanation there is that the tires can only do so much; we all know how poor the pre-highland Model 3s are in terms of sound insulation.
Again as these are EV specific tires, they were created with range in mind. With the Continentals, I averaged 230wh/mi over 40,000 miles. I've since driven 1,500 miles with the Kumho tires, and I am sitting at 218wh/mi. Not a game changer but certainly an improvement nontheless.
Overall I am very pleased with the Kumho tires.
For your size 185/55R16, the best “cheap but not garbage” all-season I’ve found is the Kumho Solus TA31 they’re reliable in winter slush, quiet, and usually one of the lowest prices without feeling unsafe.
On my old Pontiac Grand Am I ran Kumho All weathers and if their speed rating worked on my new 300 I'd run them on it too. Great tires with great grip unless you hit a wet iced spot but nearly all tires fail on that.
Incredibly lucky. Send those to Kumho, they would happily use these photos.
I use kumho w my sportage. Theyre quiet and lasts long.
4 brand new oem Kumhos for my forte installed where right at $480 out the door.
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.
Recently bought a used Subaru Crosstrek for my daughter, and CarMax clearly had put new tires on them — specifically, Achilles SportTouring A/S.
I know nothing about this brand or model, so I can’t say what their wet or snow performance might be (or any other parameters, for that matter).
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).
