Newer ST tires may carry a L (75 mph) or M (81 mph) speed rating.
Most LT tires we use on the tow vehicle can carry a R (106 mph) or a S (112 mph) for P tires.
Speed rating has to do with the tires ability to cope with internal heat issues rather than how fast we can go.
Heat.... Brings up a topic I would like to see expanded upon.
I have never checked my tires temps. I am sure some here have... Just what are typical temps?
What is considered acceptable?
Where on the tire should one take a reading?
Over 125 degrees you'll pull your hand back from under your hot water faucet at home. That's my benchmark so I just feel the tread, sidewall and hubs of my 4 TT tires/wheels. I'm looking for one warmer than the other. I may modernize this year and get an infrared gun. Obviously temps will feel warmer on a 90 degree day vs 50. We should start a fresh thread I'm sure many have the same question
