The Option tire takes a new look at what makes a good street tire, and goes way beyond just making a tread pattern that looks good. Featuring our Slidewall Technology which is our own ultra-hard low friction compound that helps reduce drag on grinds and increase the life of the tire sidewalls plus a ton of other features. The center section of the tire is smooth, so it is nice and fast, but the tread is actually thick for this section. The thicker tread has the benefit of increased shock absorption and then abruptly tapers down to a thinner thickness. By having the tapered tread connect to the thick center section, it offers support so there is no squirm and the tire is stable and at the same time reduces the tire weight because there is no benefit to the thicker tread on those sections of the tire.
