i had aluminum 10s that were dialed and never blew a bead running them on 37 goodyear mtrs at 3psi all day in the snow everytime i went out. i wanted to be wider so i got some steel wheels with 2 1/2 BS on a 10's again and its been the worst thing ive ever had to deal with. i need new wheels and they will be 8s. i think because the wheel is narrower the tire is pushing against the rim harder than the 10s. go 8s.
