Speed and blown tires

6. My personal opinion - I won't run LT tires because they aren't rated for the weight. And there also seems to be an argument for the stiffer sidewalls on trailer tires that LT tires don't provide. But I do understands why some would run them as opposed to a cheap ST tire (AKA Towmax).

Hi,

Not trying to change your mind, just I read your wording and it did not come out right, "I think". I do agree what you "might" be saying if used in the right context. I am just trying to give some options as LT tires done right does work.

I do agree with you that exact tire size and load range of ST verses LT tires is not equal. Many times LT is lower and as such, doing a direct exact change out in the same size tire and load range is not the right thing to do. I did not come away with that meaning as you stated;

I won't run LT tires because they aren't rated for the weight.

Maybe you meant what I was explaining, just the words did not sound that way. Maybe a typo?

The issue can be if the "person" applying the LT tires does not follows through on all the needs to allow LT tire to work, not the LT tires themselves.

"Some" options to use LT's which are rated by the tire manufacture for trailer service are:

1. Upgrade to LT tires in the same size tire but to a higher load range if one is available as long as your tire wheel can handle the higher pressure.

2. Upgrade wheels in the same size to allow the LT in the higher load range as this will fit the camper with little modification.

3. An option which may be more cost then the above 2 depending on the situation is to increase the wheel and tire size to get the correct rated capacity and pressure for the LT tire.

In any case, going to an LT tire will cost more over ST tires in most all cases. Doing this change is not a cost savings program.

In my case, my only option was no. 3, increase wheel and tire size along with load range and deal with the suspension interference. ST225/75R15 to LT225/75R16 Conversion

Changing to LT tires done with upgrading the other needs does work. LT tires are installed every day by equipment trailer manufactures all sized correctly carrying more weight then a lot of RV's.

To the topic of trailer tires not being sized well from the RV manufacture is for sure a topic all by itself. There are RV manufacture issues surrounding the running gear itself the way they did. And then there is growing understanding by some tire engineers and tire installing companies that trailer tires in a tandem axle setup require a larger buffer in capacity to deal with the heat from the tandem axle turns. 15 to 20% more capacity is often given over the highest loaded wheel as a guide to use.

Please do not take this in a negative way. Not arguing with you as you have many good points, just clarifying the LT tire needs.

Hope this helps
