A rather broad statement for someone who is not in the tire business, isn't it? I'm not real sure if you're trying to justify your reasoning or backpedal in your previous statements and to a certain extent, I take those statements somewhat personally.
You of all people as being a Moderator, should know the power of throwing out very broad statements that are very likely unfounded. Using the terms "All" and "very few". If this is the case in your neck of the woods, I'd be very leary of buying tires from any dealer.
See, where I come from, the NW, there are twice as many trucks as there are cars. Many see offroad use, with a trailer or RV. If that "stuff" happened out here, that tire business would be "black flagged" reather quickly.
Quote:I wish I had a dollar for ever wrong weight rated tire we found mounted on trailers and another for every low pressure valve stem (50 PSI maximum rating) installed on tires requiring 80 or 90 PSI.
I'm sure you're right, but with the cost of tires and the ability to order tires online for the last 10 years, I would venture a guess that quite a few of those tires(to me 20% is quite a few) were put on after they were brought in from the customer and mounted no questions asked or no info from the customer given. So until you know the full story on why those tires were mounted in the first place, that assumption cannot be made.
Incorrect valve stems... well if the owner manager had to check EVERY one of the tires mounts, he/she would never make any money. They are giving the responsible "tire changer" the means to properly do that. And just an FYI, it is more important to have a good quality valve stem over a high vs low pressure situation.
Quote:Not to mention like it was posted OEM tires are at the limit of the trailer weight and as little as 5 PSI underinflated can cause failure
.
That is a RV manufacturers boo boo for not putting the correct tire on the trailer and they should be ashamed if they are knowingly doing that. That is not a consumer faux pa. If I had a new PU and knew that they knowingly did that and I got into or caused an accident because of undersized tires. Well, someone would have to pay and it would be me or my insurance co.

This is absolutely untrue. The mass public is ignorant and un-informed, not mis-informed or lazy. They don't know that it is in their best interest to run the "proper" inflation for their situation. They see the word "MAXIMUM" with pressure behind it. Don't assume people are intentionally being lazy or thoughless. Did you know that a tire can change pressure 2-7lbs in a day depending where the tire is in relation to the sun or temp. Nobody can keep their tires at the "correct" pressure all of the time. You'd have to check them every day.
