Q: What is the load capacity of the 00591-04638-81 poly load wheel?
A: Load capacity depends on the specific truck model and number of wheels supporting the load. Verify your equipment specifications and consult your Toyota lift truck documentation for rated load per wheel. Contact us with your truck model and serial number for exact load ratings.
Q: Does the 00591-04638-81 require maintenance?
