if your shops sells those cheap lil blank wheels for $20 sometimes they'll have a few pairs that're fairly thin. i've had a few pairs like that some myself and thought they were coo... can anybody tell me whats the "difference" between riding thinner or wider wheels?
I feel like wider wheels cone faster, but that's just completely anecdotal from my personal experience.
Also, while I'd say wheel composition makes a bigger impact on grip, in general, a wider wheel may grip better and slide less?
I personally prefer to ride thinner wheels. I only skate street, if it matters. I also think thinner wheels look better, for what it's worth.
For the OP, most Bones STF wheels are pretty thin, some more than others. You can check the dimensions of each wheel on their site. I think I remember seeing them get down to 28mm in width. I'm pretty much STF for life, too. They really are good wheels.
