Hey Noel I was on the road all day and responding to you from my cell phone and never saw this. there is some older paddle builds that's not even close to these new Extreme Skats.
The Roll out I saw at Tims Shop were all around 94 to 95+ lately and that makes them all solid 30" tires and Skat measures roll out on all tires after the buff. so that is 15 PSI and these tires should be run generally at 12 or so and they don't lose any rollout to speak of that is barely noticeable at 12 PSI. I will try and get some of the 95+ Roll out for my rears and I want to dig through the pile of fronts to get them up around 97" Roll out.
Like I said before on the tire weight the front buff is like 13 lbs and a 9 Blade rear is 16 to 17 maybe.
The Height is what everyone is looking for Tim says.
Tim has been selling tires like hot cakes all summer long all over the country and he gets great feed back from the customers on how the tires work and what not so if you have any specific questions about certain Dune areas you ride in ask Tim as he has customers world wide.
