Whoop's, I just went to their site and they no longer list weight per tire but in looking back at charts I have from ten years ago they list the LSR front runners as having a max load capacity of 1,700 lbs at 80 psi with a max speed rating of 300 mph. This is or at least was true for all sizes with the exception of the 8.00/8.20 X 15 tire (no longer listed) which has a max load of 3,000 lbs and a max psi of 70 lbs.
