We have our last autocross of the season tomorrow. Just a fun event not worth points. I run Michelin PSS on the street and BFG Rivals for autocross. I was planning on running the PSS because it was likely going to be pretty cold but now the weather is calling for 55 degrees and warming up to 60.

Would you run the Rivals or the PSS in 50 degree weather?

 

I'd run the street tires if I hadn't done it before in order to learn where the limits are. Otherwise I'd pick the set that was more fun.

 

For effectively fun runs, go with whatever tires you like the least, and want to replace the soonest

I'd have said PSS - What did you run?
