Saw this over on the Bird board. I don't know anything about them, but I thought some of running flared cars with 15" rims might have interest:

Interesting, but no mention of actual treadwear rating or any other comparative stickiness... The Miata and other vintage racers will eat those sizes up.

UTQG 140

They are Indonesian and likely licensing a tire compound design from one of the bigger players; wonder who?

Looks like great sizes for a GT build.

I see the latest PCA parade rules have limited treadwear in production class to 180.
