9/3.50-4 (9x3.5) Carefree (No-Flat) Smooth Tread, 2.50" Bead Width

The 9" x 3.50-4 Carefree Flat-Free Smooth Tire with 2.50" Bead Width is a durable, maintenance-free replacement designed to eliminate the inconvenience of flat tires and constant air-pressure maintenance. It is an excellent replacement option for several Carlisle Reliance and Carlisle pneumatic tire part numbers, including Carlisle 11-539.

Manufactured from durable Polyurethane Foam, this Carefree tire requires no air and cannot go flat. The smooth tread provides consistent surface contact and easy rolling performance, while the resilient Polyurethane Foam construction helps absorb shock for a more comfortable ride than many conventional solid tire designs.

Designed to fit 4" x 2.50" rims, this tire performs best when installed on a compatible 2-piece or 3-piece bolt-together rim. Its 2.50" bead width is especially important when replacing an existing tire, so please measure your current tire and rim before ordering.

Price listed is for one (1) tire only. Wheel/rim is not included.
