Attention!Orders for tires and wheels that are to be assembled, must be added to the cart tire first then the wheel on which the tire should be mounted. Example - An order of four (4) TIR-217 mounted on TIR-400 and eight (8) TIR-217 mounted on TIR-RX190 would be entered as follows: Qty 4 - TIR-217 Qty 4 - TIR-400 Qty 8 - TIR-217 Qty 8 - TIR-RX190 Any deviation from this format may result in the incorrect assembly of tires and wheels in addition to possible order processing delays.
