In my words
Positron 2.2" S4 Buggy Rear Tires (2) is a Buggy & Truggy tire first and a conversation starter second — the track is soft, loamy ground and early-morning tracks.
The set is 2.2" in S4, fitted rear. The point of an S4 soft compound is predictability: it gives up grip slowly instead of all at once.
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.
