Stadium Truck, Low Profile Tire Inner Sidewall Support Adaptor, Fits 4049 tire

Overview

During high traction or loaded conditions, tire sidewall deflection causes oversteer and inconsistency with driving performance. By adding the inner sidewall support adaptor and gluing it into place, the sidewall effectively becomes much harder and allows a driver to enter smoother arcs and radius turns on the racetrack. Already used in competition, the sidewall support pieces have shown to work on glued, sealed, or naturally grippy surfaces where traction rolling or oversteer is an issue. In addition, when conditions are rough, bumpy, or dusty, the additional support drives smoother and with more consistency.

At the 2022 ROAR Nationals, Dakotah Phend, in conjunction with the JConcepts race team, installed the adaptors into the Smoothie 2 tires (#4049 tire) in the stadium truck class and won in convincing fashion. On the track surface, the supports were added only to the inside of the outer sidewall and tack glued into place. The ultimate option to a massive array of tires gives JConcepts users an advantage and a larger setup window to tune in to any surface.
