Tires Kumho or GENERAL TIRE
I got a set of Kumho EVO tires for my Model Y about 15 months ago, and they turned out to be a pretty substantial upgrade from the Continental ProContacts the car came with.
I have the Generals on my 2000 Boxster. They are pretty good. I can take a 90° turn off a hiway road onto another hiway at 55mph, 60 mph is the edge of traction for a 320 treadwear tire. Spins out at 65mph.
Being picky I wish the sidewalls were a little stiffer. The ride is plusher than the Sumitomo HTR(another not bank breaking option) in my opinion.
I have kumho ecsta ZR "performance all seasons" on my 97 986. I drive the thing pretty hard, not too many curvy roads around here but it handles good. I really don't have any complaints, I daily drive this car and another.
Now I have Kumho Road Venture AT52 275/70/17 E-load. They are aggressive and are heavy but I do not rub on normal highway driving or light off road use. Good tires.
I like my General Altimax all-season tires. I did eco tires before and felt like they had no grip.
I really like the Kumho Road Venture AT51. It's quiet on the road but still aggressive enough for rough terrain. It's also three peaks winter rated so it is an excellent tire in the snow and ice. Tread life has been good also
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.

I am at 14,000 kms after 7 months I checked the tread and was at 6mm so planning to change by 20,000 miles (32,000 kms). I have already reached out to Kumho Warranty but they don't even want to try to work on something with me. I can't see myself spending $1500 to get a new set after this demonstration
Seeing as I am preparing to have to swap them out at 30,000kms I would say they may be one of the worst tires on the market. I do have them (stock) on my EV9 which I have driven relatively gently. Reached out to their warranty department and they refuse to work with me. I don't really want to spend 1500 on a product that drastically underperforms.
