Used to have an individual who insisted that the molded tire pressure number was the recommended tire pressure when starting out your trip. People who followed his advice always complained about the hard ride.

given the weight of most people’s trailers it probably is the right pressure…

That’s it? Just a poll? A quiz without any words about an answer. Seems like most of the article fell off on its trip through the internet.

Go to Roger Marbles https://www.rvtiresafety.net/ website and you can get all the information you need. You will also discover the reasoning behind the answer 65% got correct. I think Roger must be a little frustrated the percentage isn’t higher.

I was kind of surprised they didn’t offer the actual definition wording since that was the question.

Obvious…

Haha, just kidding, as in most multi guess quizzes there is often more than one correct answer. In this case the, the best answer is pretty obvious and 65% got it right.

Various tires may be different, but in most cases everyone should realize what MAX means.

Equally important is knowing what the speed rating & load rating numbers mean.

It was a yes or no question so why the multiple choice answers? I sold, mounted and balanced thousands of tires in my younger days before they even put these numbers on the sidewall. Tires are much more complex today but now you can start with the numbers on the drivers door jamb and go from there based on actual weight per tire and and ride comfort.

…until you upgrade tire load range! Mine went from “D” to “F” (No “E” available); so the plate for pressure no longer applies.

The problem is that the important sidewall info is often printed in tiny type that’s hard to read. Even when using a flashlight, wetting the sidewall, etc. But the brand name and other less important info is large and easy to read!

The sidewall info means: Don’t underinflate, overinflate, overload or drive too fast! Right?

It looks like everybody needs to ask Roger Marble again.

Poorly worded question and responses. The information molded on the sidewall can not change and can’t “be different” than what it actually is. Tires should be inflated based on the actual load on the highest loaded tire on each axle. However, that is not what the poll asked.

Absolutely right, on all counts.

I spent over 30 years in tire manufacturing and I not only know what these numbers mean, I know what goes into determining those numbers.
