I saw that one too there King. Atv Action weighed the 28x12.5" Outlaw and there was a bit more of a difference. If you subtract the 13lb wheel from the 28" Vamp (which they weighed mounted at around 52lbs., then you get about 39lbs for it. Thats a good 8lbs. in favor of the Outlaw. However, juice it up to the Wider outlaw (48lbs mounted) and subract the 7lb. aluminum wheel and it comes out to 41lbs. Overall, the Outlaws are lighter, but not by much. A 12" wide 28 vampire (if they made it) would easily weigh more. However, the outlaws don't sport the 2" lug that the Vamps do.

I would prefer the Outlaws over the Vamps myself, just dropping some info on the weight. To be truthfull, I think the new 28" GBC tires look really good.

 

Not sure how they weighed their tires. But, I got the 12.5 Outlaw on an ITP Magnum weighed at 46 pounds and the 10.5 at 40 pounds.
