good track tires for emaxx

[maximum]

I ran my new emaxx for the second time at my local brush site ( i had to unload some small tree trunks from my brothers house). There was a tall pile of fine sand that i didn't want to touch ( sand = enemy) and a bunch of big tree trunks (too big for the emaxx) and piles of tree brush wouldn't work either. But, what was there was a pile of broken roof barrel tiles. Well, that was interesting. I had a blast slowly climbing this pile and hearing and seeing the tiles shift as the emaxx paddle tires slowly made their way over the jagged tiles!!!! The skid plates were boken in properly, although i don't think i'll do that again. Anyway, what good ( LIGHTWEIGHT) rims and tires would be good if i wanted to race on a track? Thanks.:eek:
