First...there aren't any radials worth a sh!t in the 15" size.

Second...if you haven't run them yourself, why offer a comment. (not meant for you RP)

Third...if you're running 17s, then get radials.

Fourth...the groove tracking is minimal (my runflat 19s on my Vette are worse).

Fifth...flatspotting disappears in about a mile.

Sixth...let's talk apples and apples since everybody seems to get it all screwed up. As previously mentioned, the Big Letters pictured above are rain treads and are not the softer compound "Bluestreeks" folks use for dedicated track work. The Big Letters wear good, provide a supple ride, do at least as well as the 15" street radials in the rain and perform in the character of a 60s style car. I have foam under the arruminum fender wells for the pebbles being picked up...though I tend to stay on pavement most of the time.

I've used several sets through thousands of miles (long distance in extreme heat and through heavy rain/light snow) and they are the only tire I will use, though the Avons look pretty good. I've only had to plug one, which was easy given the lack of steel belts. I change them every two to three years whether they are worn or not simply due to the age (they are race tires).

Personally, I think they are safer than the POS 15" radials since the radials have no grip whatsoever that will handle even minor use of the throttle in these things, or come close to their cornoring ability at much less than the limit.

If you're a poosey...run radials. In fact, go buy a Prius, please wait one hour before swimming after you eat, vote for Nadar, hug a phuking tree and listen to Yani with lit scented candles.

And yes, I've been on the track enough phuking times in the past quarter century that I don't need to hear from folks who think life begins and ends on a closed phuking course.
