Do not forget the effect of heat on the tires. I have load range C's, keep the pressure at the rated max, also I use a TPMS system to monitor pressure and temp...one other thing - when at all possible I do not exceed the max speed rating (62 mph)...this is important...and yet I see many folks ripping by me at speeds exceeding that some obviously at 70mph or better.
You have LRC ST tires rated for 62mph max? Are you sure???
If so, dump those pieces of junk and buy something with a speed rating over 65mph. The new Marathons and Carlisle HD's are good for well over 65mph in all sizes.
Don't sweat a higher load rating unless you're near over their weight spec.
