longhaul said:Lots of trucks and trailers on the road (including some of mine) have no tire placard which is just a recommendation anyways. It carries no enforceable regulatory requirements for owners looking for a good or better tire to replace the junk the vehicle mfg has chosen.
That's really not true. Just about all tire industry standards are durived from regulatory authotity. The precident a trooper will use if you're so unfortunate to be inspected by one is CFR 570.62.
If you dont want to look it up, here is an excerpt that applies......"A mismatch in size and construction between tires on the same axle, or a major deviation from the size recommended by the vehicle or tire manufacturer, is a cause for rejection." (In that context, size is short for size designation. They don't like repeating themselves and have already used the complete term, size designation).
NOTE: Are your trucks commercially registered? If so ther tire regulations are not applicable with FMVSS standards. However, the heading for CFR 570 is, Vehicle in use safety standards.
