This is what both my rears looked like after last weekend auto-x. It wasn't
even hot outside. Is this an indicator of anything particular I'm doing wrong? About the only abnormal thing on the course was a long 180 that was not quite a hairpin but I had the gas pedal to the floor for the whole last half of it. Basically with a 2.3 and limited slip and my setup, no possible way to spin with foot on the floor. |

Do you have a pyrometer to check temps of the rubber? Hoosier can give you a temp range where those tires will stay happy. Maybe you and your co-driver just need to check temps after each run when you check pressures, and have a basic garden sprayer handy to chill things down. Insulated tire covers can be helpful too- you can make your own, black on one side to grab and hold heat on cold days, silver reflective on the other to keep heat out on the warmer days. Think the material used for windsheld sun shades you can buy at walmart. And don't let them freeze over the winter. Put them in your basement, best to be wrapped in that cling plastic you can get on rolls.
I'd hate to see you go to a less effective tire if there were ways to make these work better for you. |
