is 26x10 ET Drag too much tire for my combo?

Yes a 500 rwhp car will be easier to 60' then a 250 rwhp car.

Yes the killer bees (gokarts at Etown) video...

But I wouldnt suggest a burnout like that. I am sure that killed my car as with much smaller ones I managed MUCH better 60's. Too much heat can hurt...
