Alienation TCS 138 BMX Tire - 20 x 2.30, Tubeless Ready, Folding Bead, Black
The Alienation TCS 138 is a street-focused BMX tire built for riders who want better grip, stronger sidewall support, and tubeless-ready performance without unnecessary bulk. This is a smooth tread urban and street tire designed for pavement, skatepark use, and technical street riding where predictable traction matters.
The directional tread pattern uses a micro-knurled surface with directional siping to create more grip edges while maintaining low rolling resistance. A dual compound design keeps the center firm for durability and speed, while softer shoulders improve cornering grip and control.
This is not a dirt jump or loose terrain tire—it is purpose-built for street use.

Compatibility & Technical Notes
Good Fit: BMX street riding, skatepark riding, urban sessions, pump tracks, and pavement-focused freestyle setups.
Not A Fit: dirt jump, loose gravel, trail riding, or riders wanting aggressive off-road tread.
Tubeless compatibility depends on proper rim setup. Not all BMX rims are designed for reliable tubeless conversion, so wheel compatibility should be confirmed before setup.
Service / Ownership Context
This tire works well for riders looking to reduce flats while improving street grip and ride feel. The reinforced sidewall helps with harsher urban riding, ledges, and repeated impacts where lightweight race tires often fail early.
For riders moving from basic OEM BMX tires, this is a noticeable upgrade in grip and casing quality.
