edyvw, I couldn't find that testing. I think this might be interesting for my website. Do you have a link?

Yes, trailer tires are thinner than regular LT tires, but about the same as passenger car tires. That's all due to tread depth. LT tires use about 13/32nds new for All Season 15/32nds for All Terrain (Please note: There is a lot of variation.) where ST tires are about the same as passenger...

So how far have they moved by now - at an inch a day.

My advice would be to start by reducing the inflation pressure and running them for a short time to heat them up. 10 minutes? Don't exceed 50 mph. You're just trying to heat up the tires. Speeds higher than that will have significant centrifugal forces that are normally countered by...

Not yet. You're a couple years away.

I don't have my usual reference book - it is out of date - but I think you'll find that the wheels are different front to rear. That complicates things enough that you shouldn't trust any answer you get except from a knowledgeable source - that is to say, not here!

Could be. This sort of looks like what happens when the rubber compound doesn't adhere well with the steel in the belts. Look very carefully at the other tires. And do it periodically.

I hesitated to post in this thread because I wanted the OP to provide more data. So first, tires don't suddenly go out of balance or suddenly out of round (with a few exceptions). Tires do go out of balance and out of round over time due to irregular wear - a misalignment condition. So one of...

From what I have been able to pickup, irreversible irregular wear can show up starting at 20k miles. You need to be rotating well before that.

Mispost, opps!!

That's because they are OE tires and are built to the car manufacturer's specs.

In addition to Car and Driver not thinking very highly of them, the buying public doesn't seem interested as well. These tires only come as OE. There isn't a filled out line with many sizes. Only a few select sizes.

Let's be a bit precise: RunFlat tires CAN be used on wheels designed for regular car tires. HOWEVER If you don't have TPMS, then you might not notice when you have a flat. If your car wasn't originally equipped with RunFlats, then the wheels won't have the features to help hold the tire on...

What those cracks are is the surface of the tread rubber aging faster than it is being worn away. That means the tread is encountering heat. Nothing to worry about. The real indicator is the grooves. Cracks there are an indicator for the rubber deep inside the tire - the rubber that matters...

Opps!!!! I made a mistake: The testing pressure for the UTQG Temperature test is supposed to be 32 psi. I misread a chart. The good news is that it doesn't change the conclusions! The UTQG test will generate a lower speed!

Let's compare the 2 tests: ........................................UTQG..................Speed Rating Test Room Temperature 95F ............. 77F Inflation pressure............... 25 psi .......41 psi Load .......................................88%.............100% So, yeah, the results are...

As an old guy, who happens to be an engineer, I find this discussion very amusing. What's a low profile? 40,? 35? I remember when 70 was low profile! What I have noted is that shocks have greatly improved and it's now possible to put 45 series tires on and get the same ride performance as...

According to documents filed with NHTSA, there was a design problem. They did describe the problem in general terms, and I can't tell from the description what it might have been - only a couple of educated guesses. And a few side notes: The recall is identified as 24T009 - meaning the ninth...

Every country goes through a process as they develop into a modern economy. This happened to Japan, Korea, Mexico, and is now happening to China, and will later happen to India and some countries in Africa. Interestingly, I don't understand why countries in South America aren't. The process...

First, those charts everyone is mentioning are MINIMUMS, not recommendations. Folks need to stay ABOVE that! Second a 1996 is BEFORE the big Firestone/Ford controversy, and since that time, the car manufacturers have changed the way they do the specified inflation pressures - and in this case...
