Here is part of a post I just read...
" I do not
understand why there is such an issue on this forum on tires? Yes many RVs come with junk tires and you need to replace them with a better tire as I did.
A few people post the facts but as the saying goes you can lead a horse to water, but you can't make it take a
think the reason tires are a hot topic on each of the RV forums I try and
monitor is that most people only have their experience with their
personal car as a background. With their car they basically have learned, incorrectly, that they
can usually get away with doing zero maintenance i.e. checking load or
inflation, and they still never seem to have tire problems.
The reality is
that car companies have teams of engineers working on just tires &
wheels. The tires have dozens of performance requirements that the tire
company must meet before they can sell tires to the car company. In the
RV world I think the only requirement from the RV assembler is low
Another thing is that cars specify inflation that gives 15%
to 25% safety margin for load (with a few notable exceptions such as
Ford Explorer of the 90's with what I think was a 1 psi margin.) This means people can go
from oil change to oil change and not have to check their tires and
just trusting the service station will adjust the air every few months.
someone purchases their first RV there is lots to learn and tires are
low on their list since they never had problems before so since everyone knows tires
are just round black things that cost too much why bother to learn how
to make them last?
Then they have a failure or see someone with
an RV have a failure and suddenly they learn they need to pay attention.
What they get is "Campfire Experts" providing partially correct to
completely wrong information.
Then they discover RV forums. So they ask the same questions and with a few notable exceptions they get the same answers they got around the campfire.
I know of only two actual tire engineers lurking on various RV forums. There are few others with what appears to be solid engineering background and sadly a lot of self proclaimed "Experts" who base their answers on their personal experience rather than the Science of tire mechanics.
