yes there is a small catch to the shore system.. you have to understand why foams are not created equal..
blacks,grays, whites have more natural rubber in them
blues,greens,yellows,orange are just foam no rubber
and gas foams must be made up of lots of rubber and less foam you guys are hard on the throttle and dont lift til it's broke..so you need a tuff tire,lol .. the consumer would have to get schooled up a bit on foam tires..jaco has a web site and list all the colors..but they rate them firm,hard,soft...yuk why not post the duro readings as well? heck use both dots and shure readings..damn things cost so much anyways..
full scale tires in fact have readings like we rely on.. tread life and such...some tires are way more gummy than others..that 400.00 tire doesn't last as long as the 4 for 100.00 i say we mass email them to add shure readings...c'mon
