In my words
Supermoto S3 Front Tire Mounted on Sleeve for Pro-Spec earns its place in the Tires & Wheels bay for one reason: the track is dry packed dirt and grass that rewards a mid compound.
fitted front, mounted and glued, so it goes on the car the evening it arrives. S3 sits in the middle of the range, so it is the set I would buy first and judge the rest against.
I do not hold inventory — the button sends you to the listing, and it carries the current price.

Questions I get about this set
Which insert goes in?
Inserts are not included with this listing, so budget for a set. A closed-cell insert holds shape under load; an open-cell one lets the carcass work. Heavy cars and high-bite tracks want the firmer option.
How long will a set last?
On dirt I get a full race day from a soft compound and two or three from a medium. Carpet and astro are gentler on rubber and harder on pins.
