The RV market (consumer) dictates that most buyers shop on price not long term quality. Else why do we have Harbor Freight and Walmart?

Take one of the two LT tire sizes above and tag them with 65 mph speed restrictions and what load rating could they place on them?

Chris. Glad to hear you are making some progress on forcing RV mfg to make better quality product.

It might be technically possible to make a tire as you suggest. The reality is that with the proven track record of RV owners not properly maintaining their tires (Load, Inflation & Speed), why would any tire company want to expose themselves to bad press and potential liability when a tire fails?
The driver always claims they never drove fast and always maintained inflation (even when there is physical proof otherwise).

Now as technology improves maybe a combination of TPMS and a black box speed recorder along with something to sense actual load would allow the tire co. to defend themselves.

I have heard of million dollar lawsuits being lost by the tire co when the drunk driver drove off the road at 100 mph+ and a tire was found to be flat when it came to rest at the bottom of the cliff. or of a tire being judged "defective" because it was flat even when there was a railroad spike stuck in the sidewall.

These are some of the items that drive the market place decisions.

There is technology available today that actually makes a case for reducing the load rating of tires on tandem axle trailers by 20% or more but the RV lobby would fight any such move so I am not holding my breath for load ratings to become more technologically correct.
