As you know auto companies approve a specific specification tire for application to new vehicles. They do not simply select a size or brand or even design but a specific specification with compound and construction features fine tuned for that exact model vehicle.
For a good many years it was my job to obtain the approval of various tires on specific vehicles.
Have you always used only tires built to the specific spec that was originally approved?
RE my guidelines. Had to start with the basics. You can of course choose to only use the same tires as the ones that came on your RV. I do have to wonder how some are to do that given that there is no dealer network available for many of the no-name tires supplied on many RVs.
I guess we will have to agree to disagree on the question if RV owners have to replace the OE tires with identical tires or not.
Tire fitment regulations for vehicle manufacturers are not binding on the end users. However, tire industry standards when followed by vehicle owners do not allow much variance.
Standards about size and strength of replacement tires are almost completely standardized and require the vast majority of tire manufacturer retailer's to follow suit with the tire builder's SOPs.
Individual RV trailer owners can install whatever tires they feel safe with and have confidence in. However, I personally feel compelled to point out safety factors overlooked during the selection processes.
Trailer suspensions must also be scrutinized. Will a trailer designed to accommodate 8PR polyester cased tires at maximum loads of 3000# support a completely different design such as a 14PR steel cased 3750# tire?
This is a verbatim quote from the tire safety section of a 2016 RV trailer manufacturer's owner's manual: To maintain tire safety, purchase new tires that are the same size as the vehicle’s original tires or another size recommended by the manufacturer. Look at the Tire and Loading Information label, or the sidewall of the tire you are replacing to find this information. If you have any doubt about the correct size to choose, consult with the tire dealer.
Do you have a valid suggestion as to how a tire retailer is to work around that safety statement from the vehicle's manufacturer?
Tire retailers use their own judgment to sidestep that safety warning all the time. In fact they may not even know of it's existence.
