Tires Kumho or GOODRIDGE
Kumho is a well built tire from Korea.
the Kumho TA51 (assuming TA51a as it is the current production) is a well reviewed and tested very low rolling resistance tire, thanks to a silica-enhanced tread compound. Most reviewers and owners over time generally note a small INCREASE in fuel economy of 1-3 MPG.
I had two sets of the Kumho Crugen HT51 SL. I liked both times and they lasted about 40,000 miles each. Seemed low but they're snow rated so I know those don't get as many miles because the rubber is softer. They handled great in snow/sleet/ice and enabled my front wheel drive van to go through lots of winter weather driving.
This last set (third owned) pissed me off though and barely made it 18,000 miles even with proper inflation and alignment.
I went with Kumho, competitive pricing and I’ve had them on a few years now and 30k miles. Still looking good
got some kumho crugen HT51. similar to a michelin LTX. these are E load rated. i have 6 of them on my 24ft class c. bought these in 2020. we've put on over 30k miles with them. still very good
Got good ride tires for my 370z they held up around 150mph several times no issues or warping but they have horrible traction my car now feels like it has 400hp definitely recommend
I find Kumhos Start going really hard as soon as the first few mm come off. Great for longevity but not great for ride and grip after first year.
I heard Kumho don't last very long, but are good for the first 10,000 miles and not good at all by 30,000 miles.
My current car came with Goodride tires from the dealership. While I didn’t rotate them they wore down to 4/32nds as well rather quickly and became scary in rainy conditions.
730s are pretty disappointing as an autocross tire. They thrive on heat, but it’s hard to get them hot enough that they will work well for autox. They are awful in cold weather.
