Some new tires.They doesn't stick as I hoped,but they are heavier and wider,so this prevent rollovers a lot.Added coper wire end BB's helps too.Front wheels-35gr. each,rear 27gr.And the truck looks good.
This is the one.Direct fit,no mods neded.

Just cut the tires a bit.Now they have more flex and grip.Not much as a real crawler tyre,but close enough.The rubber is harder then it has to be,so nothing more you can do abouth it.At least I like the look of the truck.:ror:
