Beware of old ST tires!!

Thanks for the reminder to all AMXpress - I read so many times here that "the tires still look new" etc., etc., etc. With RV tires, you must not go by that but instead replace according to the code on the side. We've done that and have so far been safe. On our last RV, the tires were a couple of years from the code replacement but they showed crazing on the sidewalls so we replaced them. Our current tires are ST. We're full aware of the problems some have had but also aware of others that have driven safely before replacing by the recommended tire code.
