Well, I run Kourse Kings all round on my Slash 2wd (only on astro mind you) and they are ace. Wear rate is unbelievable, I bought a 2nd hand set off here bout 6months ago and I'm still using them now, they've barely worn at all
SO fantastic value for money.
I think other tyres worth looking at are J concepts subcultures, HPI Attk's (had a set of these, but not as good as the KK's on astro imo) and Bullseye's
