Just got my first rc car, a slash 4x4 and am loving the brushless power!

I have found an ad on a trading post site where a guy is selling three sets of wheels & tyres from his nitro rustler and bandit. I am wondering if someone could please tell me if these will simply fit right on my Slash? Does a stock Slash 4x4 and stock rustler and Bandit take the same wheels? He is selling the 3 sets for $50 so it sounds like a great deal and there is a pic and the tread looks new on two sets and maybe 75% on the third set.

Obviously I'm brand new to here and into rc so any help would be very much appreciated.
