Seems like whatever scale is used there is a difference in weights so it can go either way + - 1 lb. The Attack weighed more than I thought and the Slipstreams really feels light holding it just as the J-SPL does. I would like to get one or two more accurate scales to see if there is any difference in my original testing. IMO the Slipstreams and J-SPL's can't be beat for their/weight cost.I have seen in many other places that the slipstreams weigh more than that. There is a mix up here.
The 15x6.5 weighs 11.9 pounds.
The 15x7 weighs 12.9 pounds
The 15x7.5 weighs 13.7 pounds
the 15x8 weighs 14.7
Wheelweights.net... check it out. it is almost always right on.
Me too. .. . I'm no an engineer, but it doesnt take one to know that to make a 15x8 that weights 11lbs takes a lot of work. Therefore they'll be a lot more expensive. Also, the 15x7 or 6.5 whatever are not that light, what could make anyone think that bigger would be lighter. :bang:Haven't had a 15x7.5 slipstream in the shop but I sorta doubt it's 11.9 lbs
