In my words
Valkyrie S4 Super Soft Off-Road 18 Buggy Tires 2 for Front or is the Buggy & Truggy rubber I reach for when the track is soft, loamy ground and early-morning tracks.
fitted front. The point of an S4 soft compound is predictability: it gives up grip slowly instead of all at once.

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.
