Slicks

I got on a new set of Yokohama Advan slicks a few weeks ago at our local track. What an incredible difference it is to have that much traction. Breaking was insane, and cornering was so much fun. Don't know how long they will last, but they are sure fun!

Slicks longevity

Just the zero squeel is worth it to me... There are are a few longer lasting DOT "slick" hypothesis out there but I like Hoosier's R6 recommendations:


The first laps for the tire are critical for setting up the durability and competitive life. The first session should consist of no more than 10-15 minutes of running. The early part of the session should be run at an easy pace, with the speed gradually increased until the end of the session. The final lap should be run at the fastest possible speed. The intent is to achieve maximum tire temp on the last lap. At this point the car should be brought in and the tires allowed to cool at a normal rate.

During the initial run-in process, the inflation pressure should be 3-5 psi higher than you would normally use. The best progression would have the driver taking 4-7 laps to accomplish this break-in. Each lap should be approximately 7-10 seconds a lap faster than the previous lap. The goal is to have the tire temp as high as possible on the last lap without "shocking" the tire during the warm up laps. In essence, no wheelspin, late braking, or sliding. The last lap should be at, or very close, the maximum possible.

Thanks for the break in description. I definitely took my time with the first few laps. Slowly bringing up the speed. But once the tires were broke in, it was time to go!

Is this break-in routine manufacturer specific or good for all slicks?

Break-in (Slicks)

Not sure but it seems like a lot to think about, I suppose if you want maximum life and performance you follow the instructions per manufacturer ...I'm considering paying $15.00 a tire from Tire Rack to have them ready to go...

You can look them up. Yokohama Advan on their web site. I'm using 245 in front, and 305 in the rear. They fit great, and run really smooth. I like the fact that they are made from Orange peals. More oil to use in the car!

The yoko's are probably the most cost effective (the non cup ones) slicks out there. They are not the fastest, but definitely can help you get used to driving on slicks, and have far more grip than anything with tread on it. They are extremely light, and with a good alignment will last a good while before cording. They are prone to get greasy if you overdrive them though.

I like the Hoosier R80/100 as well, they corner like magic.
