ST or LT

My 2008 2955 RL needs new tires but I'm getting contradictory advice. Currently I have LT 235/85R 16 tires that are G rated. E-trailer says I shouldn't use truck tires (LT) and go with the trailer (ST) tires. My tire salesman agrees, but friends I know have ditched the new trailer tires on their rigs and changed to the LT tires; Says E rated tires that are 10 or 12 ply should be fine. Want to be safe, but at over $300/tire want to be smart too. What to do?

For your 2955RL, LT tires are fine for that weight. I have run Michelin XPS Ribs E rated LTs on my 2007 3075RL since 2008. And they are weight rated fine for my weight.

And I am far from alone in running LTs on the lighter trailers.

When we had our 2955 we ran BF Goodrich Lt tires and they were fine. Far better than the ST made in China tires they were putting on then.

I would NOT under any circumstance put cheap Chinese ST tires on your camper and the good G tires are an over kill. A good LT, E rated tire is perfect for your camper.

LT or the only ST I would put on is the Sailun 637.

I'm with everyone else. If my trailer was light enough I'd have LT tires on it. LT tires are required by the feds to have a safety margin in them due to the fact that people ride in those vehicles. ST tires are not required to have a safety margin.

Maybe a little explanation is in order. STs are OEM on trailers. LTs are OEM on our trucks. ST tires are mostly made in China. LTs are mostly made anywhere but China...USA, Japan, Germany, etc. You can probably count the number of long time Montana owners who have NOT had an ST tire failure on one hand. Plus you can probably count the number of LT tire owners who HAVE had a tire failure on one hand.

Our 2955 came from the factory with LT load range E Generals way back in 2002

I have a 2006 2955RL, and run BF Goodrich Commercial TA s with no problems. I recommend LT tires to anyone, if you can get the weight rating you need. These load range E tires have served us well.

I have a 2005 2955 RL and am running Bridgestone Duravis R500 LT tires. These were recommended by Lonnie B who has a tire shop and is a Montana owner. You might still be able to do a search using his name. I have been very happy!

I like doing business with trailer.com BUT you can't ALWAYS rely on information they provide you. Just last week I asked a question about a specific product before placing an order and was given bogus information. When I questioned their answer they totally changed their answer. I will however continue to do business with them as anyone can make a mistake.

This happens every time this subject arises! And no one ever touches on the most important data in the answer.

Firestone E rated truck tires' weight ratings are at 106 mph. Other LT E tires may be even higher. An ST E rated tire is load rated at 65 mph. This means that at 65 mph an ST tire's load capacity is maxed out and starts diminishing as speed increases.

Understanding how important this speed/weight rating is, is more important than where the tire was made when determining capacity. At 65-70 or even 80 mph, an LT tire is not near is's load capacity.

The import issue is also important to me. I have always been able to find US made LT tires for my Montana.

I agree with fauch. Some people maybe most are happy running 60 65 but I'm not. No one should put 65 MPH tires on a camper and send it out on 75 MPH interstates.

Not sure i understand this statement:
"I'm with everyone else. If my trailer was light enough I'd have LT tires on it."

This is in relation to E rated tires. E rated ST tires are typically rated for over 3,500 lbs. E rated LT tires are typically rated for less than 3,100 lbs.

You have to consider the SPEED RATING
At 65 mph the ST is DONE. and capacity keeps diminishing
At 65 MPH on an LT tire you're a long way from load limit.
On Firestone Transforce HTs (E Rated) The Diminishing load limit as speed increases does not get to 3402 (it's load limit) until 106 mPH.
The physics of decreasing load capacity as speed increases is not fake news.
It's why there are so many ST tire blow-outs
