running wider tires in the rear on a stadium truck...ok?

[blueb8llz]

whats up, i wanted to get your opinions on running wider and slightly bigger tires on a vxl rustler.
the seller says it gives him better traction. is this bad for the truck at all? im thinking it may ruin the diffs. can you gives think of the pros and cons to this setup. will it make the truck wheelie more etc..etc..

[RUSTY XL-5]

I dont think the diff will be affected....the rusty only has on diff. Not like an E-maxx where different sized tires would be a problem. ;)
