man you really shouldent have a problem at all, i dont know what you have for mods, but you should start by doing a brake stand, then turn the wheel and slowly let off the brake and turn it into a spin, really shouldent be a problem unless your track-lock is GONE, and you get one-tire-fire everywhere. i can do em easily with my 275's mounted on 18's, no problem even with my stock trac-lok. although its not as easy as when i has the 235's its no problem, even when i had my stock 302.
