I broke one of my rear wheels in northern MB on my 2011 R800. I'm running 27 x 10 x 12 black mambas. I'm not a very knowledgeable person re ATVs. My rear wheels are yellow beadlines and look to be stock beadlines w/ 4" offset. I'm looking at a pair of 12" yellow beadlines on kijiji out of Winnipeg with the tires mounted. The seller says they r skinny wide which i now assume from the forum r the tires. Will my black mambas fit on those wheels if they r standard 7.5 W? Do skinny wide tires go on the front as well? He wants $250/ pair w/ heavily worn tires. I don't care about the old tires, I need a wheel and having a spare won't hurt. I asked the guy to measure the width of the wheel. The tires do look less wide than what I am using but don't look narrow enough esp. if they r skinny wide to be fronts from the pics.
