My Maxxis D tires arrive at shop tomorrow. I also called Lions Head and they said the Sumec Rims could handle D range at 65 psi. I bought some 1 1/4 " steel bolt on valve stems from Oreilly Auto Parts rated for 150 psi. I will put my TPMS sensors on and have tires balanced with sensors in place. I plan to run them 65 psi/ 65 mph max.
