Man. . . how do some of you wear out street tires some quickly that it seems you have tried several different kinds in a short period of time unless you are running autox events on street tires?

I put almost 45K miles on the first two sets of Goodyear Eagle GSCs on my daily driver. The only reason I removed the last set after 45K miles was my concern about running them in the winter rains (It generally doesn't rain in Los Angeles from (May to December). I've only got 114K miles on the car, so that is only two sets of GSCs. Now on set #3.

I pulled the factory GSCs off of my autox car after 25K miles, but I was running the car on street tires for the first five months of autox events.

Yep, I ran my RE71s on the street and track (15-18 autocrosses), as well as some fun mountain runs.

I've had a little bit of time to test out the Kumho 712s and compare with the old RE71s. The Kumhos still need some time to break in though, so what I can offer is only initial impressions.

They seem to be pretty sticky. I tried a couple highly aggressive maneuvers - a braking test and a test of full throttle acceleration around a turn with a rapid gearchange in the middle - and heard nary a peep from them. The downside, at least for now, is that steering feel is pretty poor. This could be due to my new wheels or the fact that the Kumhos actually have tread, though. SCCAForums Image Braking feel is also lacking, and more pedal effort is required, though stops are still very short.

My early impression is that the Kumhos have overall grip levels comparable to the RE71s, but the RE71s felt so much better in terms of telegraphing their proximity to their limits while filtering out jarring road bumps.

Note that the MKI MR2 has some of the best, most direct steering in a modern car. I doubt those of you with power steering would be able to feel such a difference.

No verdict on the Kumhos just yet. I've been told they will get better, dynamically, with age. And perhaps it's not fair to compare bald RE71s with full-tread Kumhos. SCCAForums Image

Just some food for thought.

Some of us cant afford race rubber. I run auto cross on my Kumhos street tires (the 712's in 205/55/16) and I love them. On my Subaru I have yet to find the limits, I even drove them on Watkins Glen and the car just gripped. No slimy feeling after some hard laps, just awesome grip.Best bang for the buck mod I have ever done. I will definetly be replacing them with the same. They do really suck in snow, and they are very temp sensitive. Like someone said, totally different tire when its cold out.

I just bought some 711's. Can anyone tell me the difference between the 711's and the 712's?
