Whats the difference between JB foams inserts and a molded insert?
The JB foam is, hence the name, a foam insert. It's made of lightweight foam, and a set of four weighs less than one molded insert.....
But finding Sorex 32's and JB's around here is pretty tough. So maybe that's why Americans (in my area) choose 20's/24's/28's.
Aha....
Deal! I will be mounting these tires onto the Xray rims. This season I've been a pretty consistant A-mainer, so I do hope not to crack anything, but my own lap times. Plus the tires sit so much better on them. Which brings me back to the question of what are other good alternative wheels?
The Barracuda, Speedmind, Proline velocity, Schumacher, Losi, Nosram/LRP Vtec, and some more... The easiest wheels to crack are the Sorex wheels, they're good, but solid like thin glass....
