hey guys, I'm just getting back in to scootering and I was riding my old set of yaks, the ones with 78a rubber, and I rolled the rubber off of the rim. Now these wheels were pretty worn down and I'm a lot heavier than when I got them. I'm looking at getting a new set of yaks, but don't want to roll the rubber off of them too. I loved how much smoother they were than the razor pro wheels, but is it worth buying another set or will the rubber just roll off of them because of my weight? Or did it roll off because they were worn down. Will the 88a yaks last longer or not roll off the rim as easily as the 78a? Will the 88a yaks even be any smoother than the stock razor pro wheels? Thanks for the help.
