"I run LT truck tires, not trailer tires."
Like Ron, a great option many people choose.

I know this has been rehashed many times but is there truly a reason we con not run good quality car or truck tires on our trailers . It seems that specific for trailer tires are not as good quality and seem to blow or disinagrate often and have lower speed ratings . I know of some people using car or truck tires with out issues. Some say they will bounce less but on a small trailer they seem to bounce a lot anyways . I think I'd rather spend more on a good longer lasting tire not trailer specific than replacing tires constantly after little use but being a manufacture of a trailer and renting out trailers of course we must go the proper and legal route .

rv.net has plenty of threads on that if interested.

I wonder if the new, thicker tread also stresses the tire more due to centrifugal force.

This might be a better source for up-to-date vehicle laws, the link will take you to towing speed limits but there is a whole list on the right of other concerns:

Cool RPM at 80mph

80mphx5280ft/mile=422400fph
422400fph/60min/hr=7040fpm
7040fpm/60sec/min=117fps
117fpsx12in/ft=1404ips

24.1in (ST175/80R13dia*)x3.14159265(pi)=75.5in(circumference)

1404ips/75.5in=18.6rps
18.6rpsx60sec/min=1116rpm

80mph=1116rpm

*tires on my Trillium




BTW, sunny side or shady side also makes a difference in tire heat.

Road hazard that causes tire to slowly lose pressure can lead to a blow out pretty fast. Lower pressure causes tire to overheat which causes more tire squirm which creates more heat.

Something that gives you a flat causes you to pull over, on the other hand a nail that takes you 5# under pressure might not be felt by the driver but cause the tire to degrade rapidly to a blow out. Which I believe is generally the pressure blowing out the side bead rather than the tire itself popping. However at speed the tire just disintegrates from the total loss of pressure.

Hmmmm... We still haven't gotten an Age Date report on the tire that failed or at least it's matching twin (?) on the other side.

Another troll here playing with numbers:
centrifugal acceleration on the rim of a rolling wheel is v^2 x R
(velocity of travel squared times radius of the wheel)
80 mph = 35.7 m/s
radius 12.05 in = .306 m
acceleration = 35.7^2 / .306 = 4178 m/s^2 = 425 g's

(I like metric units for this stuff.)
Every gram of that tire tread "weighs" 425 grams!

As Homer Simpson would say: Tires, is there anything they can't do?

Slowing down to 60 mph takes the forces down by a factor of .56 - now that feels much better.

The very reason we have continuous pressure and temperature read out on our trailer tires. Though it has alarms for low/high pressure the read out is right in front of Ginny and she can see trends.

Once a tire on the CRV started to slowly lose pressure. We stopped and it was one of 'Roger's' nails. We put the spare on and we stopped we plugged it.

I'm in a similar boat Ron but using Extra Load P's. They work great and at 38lbs pressure provide a plush ride for our vintage 43 year old trailer.

I too believe we could tow at 90MPH but will leave that kind of fun to the pro's at the test track.

Speed

If I go over 60 its purely by accident. You kinda blow any time you save changing a tire.

Then can anyone tell me why you would not run a trailer tire at full inflation? After all, no one is riding in the trailer and expecting a smoother ride.

I'm tying to understand why, when the tire companies employ a R&D department to design a tire specifically for use on trailers, that anybody would decide they know better than these companies and use a light truck or passenger tire instead.
