In my words
Rear Positron 2.2MC Clay Off Road Buggy earns its place in the Tires & Wheels bay for one reason: the compound does the talking.
The set runs 2.2" across, fitted rear, 2 pieces to a bag. Rubber ages on the shelf as well as on the track, so I run sets rather than hoard them.
Stock on small-batch sets moves quickly, so the listing is the honest source for what is left.
What Pro-Line says about it
- Futuristic Directional Tread Design
- Angled Connected Bars for Maximum Forward Bite & Unmatched Corner Speed
- Improved tire wear over previous race tires
- Tune Performance by Choosing Tire Direction
- Outlast the Competition
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.
