I was afforded a unique opportunity to test how much difference, if any, cup tires would perform at an AX event compared to street tires. I was asked to help design and setup an AX course for our Sunday event. I ran my street tires on the setup day and after a couple of laps did a consistent 46.5 second run. at the event on cup tires I ran a 44.2
A beautiful day at Zepherhills Air Port with a good turn out of participants. I believe we had 40 drivers and a variety of cars. Unfortunately for me, I had one of the top dogs run in my class who even took first overall with a 42.2 (beating our national champion) but I took second in class and in the top 5 overall. the total scores did not get posted yet but it was fun anyway so here is one of my faster runs and one practice run where I did not do so good.

What street tires were you using?

harryrcb

Street tires are Micheling PS 2, track tires are Michelin ps cup

Euro951

If you used tires made more for autoc4ross your times would be closer to the cup tires, maybe top the Michelin cup tires. The cup tires aren't meant for autocrossing.... I haven't autocrossed for a few years but the old REO1r Bridgestones were really good.

You are right, I participate in all the DE's so those tires were meant for that but they still work better for the AX than my streets, next year I will purchase another set of wheels with AX tires
Thank You, I try
