Stadium Truck Low Profile Tire Inner Sidewall Support Adaptor for 4049 Tire (JCO5012)

Stadium Truck Inner Sidewall Support Adaptor is a racing-grade accessory designed to stiffen a stadium truck tire’s sidewall. Glued into place on the inside of the outer sidewall, it hardens the sidewall enough to help the tire hold its shape under high-traction and loaded conditions, enabling smoother entry into arcs and radius turns on the track.

Used in competition, this low-profile adaptor works on glued, sealed, or naturally grippy surfaces where sidewall deflection can lead to traction rolling or oversteer. It also improves handling in rough, bumpy, or dusty conditions by delivering smoother, more consistent performance. Installed on the inside of the outer sidewall and tack-glued into place, it broadens the tuning range and helps dial in tire behavior across a variety of surfaces.
