AT, ST and HT tires specs

Can anyone explain the difference between at and st and ht tires? Thanks!

I suspect you've looked at a line of tires and noticed that the name was the same, but there were 2 letters that followed the name.

For example: Goodstone Classic AT, Goodstone Classic ST, Goodstone Classic HT.

Those are actually part of the name and officially mean nothing (just like the name means nothing, other than it's a label).

However, most of the time those letters give you a hint about the intended service. AT = All Terrain, ST = Street Tread, HT = Highway Tread.

Just remember this isn't universal and it's better to read what the manufacturer says the intended usage is.

Hope this helps.

Thanks!!

Hey, Roger, you can also ask Grant@TireRack he is quite knowledgeable in the rims/tires area.
