This kind of tire has been rumored for years, seems that it is finally here. A lower profile tire with stiff sidewalls will allow for slightly higher capacities on the load charts, especially above ~45° boom angle. One of the limiting factors for telehandlers has been the tires, as they were and continue to be designed for road graders. Originally companies got around the flexible sidewall tires by using liquid ballast. The situation got worse in the 90's as rental companies put pressure on the OEM's to stop using liquid ballast due to high repair costs. This forced the use of more steel weights to make up the difference, which usually can't be put in the ideal locations, which necessitates even more weight - and as you can guess the GVWs went up. Now if other tire companies like Galaxy follow suit the prices shouldn't go up much. And hopefully they prevent a couple tip overs.
