BSR 1/12 Spec Tires F1233-S

If you have spent any time on a 1/12 pan car track, you already know how much tires matter. The wrong compound and your car is either pushing wide through every corner or snapping loose on exit. BSR built these 1/12 Spec Tires specifically for the demands of competitive spec class racing, and the difference shows up immediately in how the car responds.

These tires are molded to tight tolerances so you get consistent diameter and durometer across the set. That consistency is what lets you trust your setup notes from run to run. When every tire in the set behaves the same way, your tuning changes actually mean something.

What racers notice right away:

Predictable breakaway that gives you time to catch it rather than just spinning out

Consistent grip from the first lap through the end of a main

Compound matched to spec class rules so you are always legal at the scale

Diameter and width held to tight production tolerances for balanced handling

Whether you are running a club points night or a regional championship, these tires give you one less variable to worry about. Mount them, glue them properly, and focus on driving.

Sold as a set. Fits standard 1/12 pan car wheel hubs.
