Tire Repalcements

Unfortunately he left out some key bits of information there. So at best that little vid was simply incomplete.
Sadly, it's been my experience over the years that tire salesmen are often poor sources of good tire information. Mostly what they know how to do is sell tires they have in stock, or can easily get that day from the local warehouse.

Which tire is likely to be a better tire ?
===========================

To which I say, these two statements get this whole discussion down to the basics. And that is, we really have no way of guaranteeing that we will get absolute trouble free performance out of "anything".
But what we can do is make informed, well thought out choices, and in so doing, we will improve our odds of success.
We are all adults here. We've all been around long enough to have a pretty good feel for what quality is, and how to shop for it.
This whole thing about choosing tires really does not have be so complicated. We don't have to know every exact detail about a product to make good choices. We just need to know how to choose.

I think everybody on this forum would be able to choose which is better: a ten year old Toyota, or a ten year old Yugo.

All I know is I am confused. i guess i will run the tires that came with the trailer for 3 years ensuring the inflation is kept correct and they are covered from the sun and then decide whether to go 16 inch & lt. my trialer certianly seems to have enough clearance for 16 inch.

Why would we assume that both the Chinese tire and the German tire were made of the same materials in exactly the same way ?
Everybody knows that German products have consistently been some of the highest quality automotive products for 6 decades .
The autobahn and the stretches of unlimited speed restrictions dictate that German cars and tires be capable of high speeds without killing somebody .
Everybody knows that Chinese products have consistently been some of the worst automotive products built to the cheapest price standard .
Why would we assume the German tires are made of the same materials as the cheaper Chinese tires ?
The Chinese tire is built to the cheapest price point possible .
Why would we assume that the $ 89 tire is an equal to the $ 156 tire from the same Tire conglomerate ?
Regarding the cubic volume of each tire the 225/75R15 is shaped more like an oval ( 6.3" tread width ) , and the 225/70R15 is more shaped like a circle ( 7.7" tread width) .
I did not provide that info in the quiz .
The calculated cubic volume of each size is very close .
And the obvious .
Why would we assume that a tire designed for maximum 65 mph is an equal to one designed for 106 mph ?

I still read lots of stuff from "experts" on not using LT tires. This seems like on of those subjects you can ever get a straight answer on.

I think TPMS monitoring system is your best option

Wise choice in the long run.

The war has been going on for a long time with the usual culprits :)

Tire One
225/75R15 load range D
diameter = 28.3" x 8.8 " section width
Max speed rating 65 mph
Tire weight = 31 #
Made in China
Cost is $ 89 each
OR Tire Two
The 225/70R15 Load Range D
diameter = 27.4" x 9 " section width
Max speed rating 106 mph
tire weight is 33 #
Made in Germany
Cost is $ 156 each
Both tires are made by the same manufacturer .
Both tires use the same wheel and fit in the same space under the trailer .

Oo, oo, Mr Cotter, pick me. I know the answer to this one!

The 225/75R15, because it has more natural load carrying capacity - assuming both tires are made with exactly the same materials in exactly the same way.

But I think there are some missing pieces of information. First is the letters in front of or behind the tire size that tell the intended service of the tire. There is also the issue of load carrying capacity - which is kind of dependent on those letters.

And then there is the bit of information we will never know the answer to - and that is what is the ACTUAL materials used in the making of the tire. Even though they may be made in different places, that doesn't mean there is a difference in quality, nor design. On the other hand, they could be completely different. We just don't know.

Tough, tough, tough describes the Goodyear HMG 20/20 Bias ply tires. Best trailer tire I have ever used. D rated, made in Canada for U-Haul. (when you google them, the picture of the tread is not an accurate depiction.) I averaged 75 mph with an 8500 lbs gross weight trailer and the temperature per the monitor never went over 96 degrees. Pressure stayed steady also. Love these tires.

With two different trailers have had tread separation and sidewall bubbles on tires made in China with under 2000 miles. Just turned 4800 miles on my Goodyear HMG 2020 and they look like new. And let me tell you, the roads on this recent trip were ROUGH.
