You don't have to be the original purchaser to file a complaint HERE.

RE fewer reported problems with LT. I would offer two possible facts that contribute to a lower failure rate.
1. The owner has now learned the importance of proper Load, Inflation and inspection of the tires.

2. LT tires in RV application have a 75 mph Max Speed rating rather then the often exceeded 65 mph limit for ST type tires.

Can you cite the reference for #2 please? I'd be interested to read that.

Can you show us a reference that supports replacing Original Equipment ST tires with LT tires? All of the major LT tire manufacturers see that as a misapplication of their tires.

No they don't. That's not true at all.

How are the Original Equipment (OE) tires for your trailer selected?




What is a factual answer for that Question? Not being in the RV trailer manufacturing business, I don’t know. But I do know what the regulations say. Those regulations are directed at RV trailer manufacturers. The major misunderstanding or misconception by many readers of those regulations is about how they can be applied. Just because you have read them does not mean you can apply them differently than a vehicle manufacturer or a tire manufacturer practicing approved tire industry standards.

Regardless of your personal knowledge of the industry and how it works, OE tire selection and fitment is the sole responsibility of the vehicle manufacturer. Once a vehicle is sold to a customer that customer/owner becomes responsible for all subsequent tire replacements.

This is a very basic statement that sets the stage for all tire replacements after a vehicle has been sold. “The size designation and the recommended cold inflation pressure for those tires such that the sum of the load ratings of the tires on each axle is appropriate for the GAWR.” That’s a trailer builders requirement. They must post it on the trailer’s certification label. It is the minimum tire size and load capacity - by inflation pressure - for the OE tires.

In pops the tire industry. They build tires for all sorts of situations. They are not going to countermand vehicle manufacturer OE tire selections. This is their basic statement for replacement tires; “The load carrying capacity and inflation pressure capability of the replacement tires must always equal or exceed the load carrying capacity and inflation pressure capability of the original equipment tires.”

Yup

Black,
I think you answered your own question with this statement:
“The load carrying capacity and inflation pressure capability of the replacement tires must always equal or exceed the load carrying capacity and inflation pressure capability of the original equipment tires.”

Am I understanding your post in that you believe it is incorrect to put a different type of tire on your rig?

Why would AS put them on their Eddie Bauer editions, but consider them bad on other similarly sized, and weighted TT?
Just want to make sure I understand which side of the equation you are arguing.

Seldom is there a single answer that will fit a replacement tire situation. The major LT tire manufacturers have provisions in their tire warranty packages that disallow replacing OE tires that are from the ST design with LT designed tires. Some will even go so far as to use the information in your trailer’s owner’s manual as justification.

The DOT only allows the trailer manufacturer the leeway to select OE tires. Design is not part of the regulations requirements. The word appropriate is used by the DOT. If the trailer builder decides one design is more appropriate than another design that’s their decision for that particular trailer. If they want to throw a monkey into the mix by using two differently designed OE tires on something they build it’s their monkey to deal with. Maybe AS confused the use of steel cased LT tires designed for trailer service only, with other steel cased LT tires that are not designed strictly for trailer axle service. However the decision was formulated will not effect replacement tire selections for other models fitted strictly with ST tires.

Without some sort of expert forensic proof of cause, you may just be showing a tire severely abused.

Here is another example. The condition is normal for severely abused tires on RV trailers.

Simply read the various booklets on RV tire application at Goodyear, Michelin and Bridgestone web sites for 75 mph max speed in RV application. Some other MFG have similar. Yes not all MFG say that. I do note than many smaller companies and importers have limited technical knowledge as they are not tire manufacturers just importers or round black things. Some don't even print the correct information for tire size etc.

The 65 for ST is published by US Tire & Rim Association, Tire Rack, Goodyear and others.

check my profile for info on a blog on RV tires with lots of info on tires.
