8" x 2" offset R-Trac no-flat wheels combine the advantages of pneumatic and solid wheels. These direct replacement rear wheels for the R6RT and R8RT are 30% lighter than even pneumatic wheels and features soft cushion ride, low rolling resistance, high-strength polymer hub, and no-flat tire.
Sold as a pack of 2 wheels with cotter pins and washers.
Older pneumatic RockNRoller wheels will either have 3.00-4.00 or 2.50-4.00 imprinted on the tire. The 3.00-4.00 refers to the 10"x3" rear wheels (RWHLO10X3). The 2.50-4.00 refers to either the 8"x2" rear wheels (RWHLO8X2) or the 8"x2" front caster wheels for the R12 (RWHLS8X2).
