Pressure Points have held up well on my 17.5 SC and Buggy. Not too bad on my ST when I ran a 13.5 in it. Got a full indoor season last year out of all 3 sets and if the foams hadn't broken down I would have run them this year for a while too.

Now for the ugly. I shredded a set of new narrow wishbones in a single night in 4wd SC. Ions on my 4wd buggy are looking haggard too after only one race day.

I think it boils down to how much wheelspin an individual vehicle can create. In lower powered applications these tires may make sense for you. High powered, maybe not so much.
