One person I know tried these and told me they gripped better than Toyo RA-1. Unfortunately only 5 sizes are available and out of the 5, 4 are 18"
Looks like it has potential and they are fairly cheap. I was considering using these since I have 0 chance of winning in ASP in any of my local regions.
Any one driven on these?
