Euro-metric tires

I'm making the switch to LT tires on my travel trailer. I know all about the difference between ST tires and LT tires. My experience is all ST tires fail violently. I check tire pressure before I leave and before I return. I've verified my weights are within check with a CAT scale. I've replaced the "China Bombs" with Goodyear Endurance. All ST tires still blow right around the 1 year mark. I'm not looking to be talked out of switching to LT.

My question is does anyone have experience with putting Euro-metric LT tires on your trailers vs regular Load Range E tires? The Euro-metrics @ 83 psi are rated at 3,195lbs vs Load range C @ 80 psi are 2,680lbs.

Put a tpms on your trailer and your tires will last a long time. If you are having tires blow out after one year you are doing something very wrong. Even china bombs will last longer than that if kept properly aired up. Might be time to review your tire care regimen.

Thank you for giving me the exact response that I asked not to get. I have a TPMS. It's what saved the Endurance from completely shredding my trailer side.

Ive had blowouts on my boat trailer and flatbed many years ago and replaced them with LT tires with great handling and absolutely zero problems, so I know they are "my" solution to the problem. I was looking for experience with euro-metric tires.

You are referring to tires that have a C after the size (for Commercial) and are used (and required) on cargo vans such as the Ram Promaster. They are what they are. I have no experience with them, but if you can accomodate the sizes they come in (very few sizes) and the weight range will work for you, then go for it.

I also agree that if you have one trailer that is going thru tires like you describe, something else is wrong, so don't be too sure that the LT tires will solve the problem.

its my understanding Euro size tires don't use LT or ST descriptions.

As Charles says the C in a euro tire description as a 225/70R-15 C isn't a C load range but is a "commercial" class tire and used on a truck/van/trailer/suv/etc position.

Tireman9 our tire engineer member talks about the Euro size descriptions https://www.rvtiresafety.net/2014/07...res-on-my.html.

I ran a set of Maxxis Bravo U-168 on a tandem axle cargo trailer in the size I listed above which were a D load range at 2469 lbs capacity. With just over 35k miles and 4 years of service I had no issues.

You don't go into much detail on what size tire your trying to replace and you really need to know exactly how much weight each axle/ each tire is carrying for weight. LT tires can be a good option assuming you can go from a 15" wheel to 16" wheel to be able to run a load range E tire. If you already have 16" tires the Sailun 637 load range G tire is very heavy duty and has proven to be up to carrying loads up to 4000 lbs per tire on a 16" wheel with no problems.

I personally have run Maxxis 8008 tires on my 6000lb trailers and run them 6 years with zero failers. It is a steel belted case .

If you go here https://www.michelinman.com/auto/tir...s-crossclimate and select 16 inch rims sizes, and go down the list of tires, look at the ones WITHOUT LT in front of the size. All of these will end in a C and these are the tires that the OP is referring to. For example 225/75R16C 121/120R LRE BSW which is a common motorhome size for Class C. I think this is what my '06 Sprinter chassis used.

MSPN
70411
Mileage Warranty

Section Width on Measuring Rim Width
8.00" on 6.00"

Revs/MI

Here is the same tire in the LT version

LT225/75R16/E 115/112R BSW

MSPN
72022
Mileage Warranty

Section Width on Measuring Rim Width
8.00" on 6.00"

These tires are only made in 15 and 16 inch and in very few sizes. Only three or four manufacturers make them, or did the last time I checked.
