I had Kumhos on a Honda Civic. They were low profile. The problem I had was the stems on the new rims I had an oval opening and the valve stems base were round. They would hold until I got up to speed on a freeway then eventually bend over and leak. The tires would immediately go flat and being low profile, shredded the tire and then started to eat up the rims. This happened on 3 different tires within the first 6 months. Took discount tire a while to finally figure out the real problem. I kept blaming the tires as being defective.
