Why ST tires?
Hey All, Total noob, trying to soak all this RV stuff in all at once. The Maxxis ST tires on my recently purchased 2001 TT "look" like new, but I don't know how old they actually are, so don't kno...

I WILL be towing in excess of 65 MPH at times.
I assure you, you are NOT "saving lives" but are instead putting people in danger
These two statements seem to contradict each other. While I agree that going slow on purpose just to back up traffic makes a lot of people mad does not make much sense, your anger cannot be justified if someone is towing their TT at the speed dictated by the equipment they have. Of course you should be in the far right lane, but on a two way road, you need to be patient untill you can pass. The OP doesn't go into his TT specs, but he can certanily buy any tires he wishes to have, hopefully keeping the safety of others in mind including those slow pokes who may just have the saftey of their families in mind - not making people mad. Someone else said that driving is a community effort - so keep that in mind when in this situation. Anyone passing such a person at high speed while angry is the one putting others in danger IMHO.
I started reading this thread because I don't know much about tires either, but I'd like to say thanks to ChooChooMan74 and 2edgesword for the links to the two articles. I will be looking into the manufacturers to see if they do make the statements mentioned = for instance:
Industry standards dictate tires with the ST designation are speed rated to 65 MPH (104 km/h) under normal inflation and load conditions.
However industry standards also stipulate, if tires with the ST designation are used at speeds between 66 and 75 mph (106 and 121 km/h), it is necessary to increase their cold inflation pressure by 10 psi (69 kPa) above the recommended pressure for the rated maximum load.
Do not exceed the wheel’s maximum rated pressure. If the maximum pressure for the wheel prohibits the increase of air pressure, then maximum speed must be restricted to 65 mph (104 km/h).
I like to push 70 while pulling my TT, but I have only been inflating my tires to 50 psi cold. I'll now be looking into the max pressure on my rims and if allowable, increase by 10 psi. Hopefully, I won't have to dismount the tire to do so. Thanks the the others who mentioned how to read the date codes - learned something.
