Thanks for your help guys, yes they are alloy 3.2 inch by 2.5 and have a real big offset which has tranformed the handeling.
she don't flip over now on corners. much wider than my maximizer half inch offset wheels. And the tyres are awsome i can actually drift on grass now,
they are old tyres and aren't long for this world so i'm looking for some new tyres that are as close as possible to them.
So far i have a short list of
Panther meat grinders
ofna monster spike
ofna mt spike dominator
The meat grinders are the easiest tyres to get in uk, i waited three weeks for my maximizer beadlocks to cross the pond and got stiffed by customs.
i find that having that little bit less grip than my hpi dirtbonz maximizer combo makes for a more fun driving experience
