I HAVE posted this question in the "TOWING FORUM" as well, but I don't think it gets as much traffic there:
Question is:I have a 24' enclosed car hauler trailer with a GVW of 10,400lbs, it has ST22575R15 tires (Mission brand D load range at present)(I underestand these tires are the very worst on the market-THESE came with my 2008 PACE trailer)
Anyway...I had one come apart recently, thankfully no damage to trailer!
I am looking at going to a load range E in the same size just for the extra piece of mind.
I keep hearing MAXXIS, they seem to be the very best out there, is there something a bit less expensive that is any good?
I hear mixed reviews on Carlise tires.....my local Discount Tire store has ST22575R15E Carlise for $$92.00 per tire (bare)-the el-cheapo Mission load range D lasted almost 3 years and about 15k miles.....Thanks for any suggestions!!-Rick

 

Just google rv tires. Carlisle, Goodyear etc. Or go to rv-net and sign on and do a search. It has been beat to death over there.
I personally am Running Maxxis 225/75/15 E on my fifthwheel trailer about 8000 miles now without a problem. I gross about 10,000 # on trailer. . I took off a good looking set of TowMax D's.
Most all ST tires are made in China. My Maxxis came from Thailand. Discount tire Direct sells them on line. I am not affiliated in any way. Just my .02

 

The only tires that I buy are Michelin.

 

Get a tire specification chart, Fine a LT tire E load range, that matches the specifications of your ST tires. Put LT tires on and say good by to tire problems. the ST tires are only rated for speeds of 60 MPH constant speed. Most of the trailer tires fail from seperation. Also nearly all ST (Specialty Trailer ) tires are made in CHINA A lot of the trailer mfg are going with L T tires. Most of this info comes from discussions on RV-net. go check it out

 

Thanks!! Anybody else??

 

Michilen are my tire also. Never had a blow out with on e of them.They are pricey but but no problems.

 

First thing to do when selecting tires - check the date code - some of those tires have been in stock somewhere for years.

 

I agree with Bob. The Maxxis tires are great but you pay a premium for them. If I was towing the trailer full time, then I would pay the premium for Maxxis or Michelin most likely. I will never run 15" wheels on a heavy trailer...I prefer 16" wheels with LT load range E tires. I have been quite happy with BFG Commercial TAs on my RV trailer, the price is reasonable and they handle the weight well.

 

Stay away from the Carlisle tires, they came from the factory on a horse trailer we had, and every single one of failed causing fender damage. The tire place said they will not even handle them any more because of all the problems they have had with them.

 

Michelin or LT tire upgrade.

X2 on the date code, most trailer tires dry rot long before they wear out, its time that kills them more than mileage in "most" applications.

 

Goodyear Marathon is a real good trailer tire also

 

Thanks guys!!!!! I have run the BF Goodrich commercial TA on pickups with good results, I know they make a 23575R15 but unsure if they make a 22575R15, I'm kind of afraid that the taller 235 will be too tall and raise the center of gravity, are the BF Goodrich commercial TAs a D or E rated tire? I think they are D but not sure.

 

You might want to weight your loaded trailer to see your actual weight.
Be sure that the BFG's have enough capacity.
One thing else to remember, ST tires are rated at a maximum speed of 65mph.
LT tires are rated higher.


Sorry, I missed Bobs thread. Jim

 

I didn't know about the 60-65 mph max speed on a trailer tire, though I rarely go over 65 anyway to keep fuel mileage up as much as I can for the truck anyway.

Would anyone know of a 22575R15LT tire on the market in load range D or E??
Anyone heard of 7.00R15 10 ply load range E?? I found a commercial antique vehicle transporter that uses these on his dual cal hauler with good results.

I am strongly considering buying the Carlyse load range E which is a heavier spec tire over the D range that the Missions are I have now.

Discount Tire has a "spec sheet" on trailer tires in general that says trailer tires are not designed to wear out tread wise and should be replaced every 3-4 years or at a certain tread depth, which I am starting to agree with.

The way I look at it I pull my trailer about 3k miles a year, I bought it in 2008 before it was a year old from the original owner and the 1 tire just went, so in theory I got the 3 years out of it-a CHEAP D range tire, so ANYTHING in E range HAS to be better even though the Carlyse doesn't have that good of a comsumer rating.-Discount Tire offers a warranty of 3 years or ?? /32 of tread.....I am finding basicly NO 22575R15LT tires available, plenty of the 235s which are too tall for my application.

Trailer Tire Applications
Trailer tires are designed for use on trailer axle positions only. They are not built to handle the loads applied to, or the traction required by, drive or steering axles.
An "LT" designation on a trailer tire size specifies load range only. It is not designed for use on light trucks.
Do not mount "ST" or "LT" trailer tires on passenger cars or light trucks.
Inflation
Always inflate trailer tires to the maximum inflation indicated on the sidewall.
Check inflation when the tires are cool and have not been exposed to the sun.
If the tires are hot to the touch from operation, add three psi to the max inflation.
Underinflation is the number one cause of trailer tire failure.
Load Carrying Capacity
All tires must be identical in size for the tires to properly manage the weight of the trailer.
The combined capacity of the tires must equal or exceed the Gross Vehicle Weight (GVW) of the axle.
The combined capacity of all of the tires should exceed the loaded trailer weight by 20 percent.
If the actual weight is not available, use the trailer GVW. If a tire fails on a tandem axle trailer, you should replace both tires on that side. The remaining tire is likely to have been subjected to excessive loading.
If the tires are replaced with tires of larger diameter, the tongue height may need to be adjusted to maintain proper weight distribution.
Speed
All "ST" tires have a maximum speed rating of 65 mph.
As heat builds up, the tire's structure starts to disintegrate and weaken.
The load carrying capacity gradually decreases as the heat and stresses generated by higher speed increases.
Time
Time and the elements weaken a trailer tire.
In approximately three years, roughly one-third of the tire's strength is gone.
Three to five years is the projected life of a normal trailer tire.
It is suggested that trailer tires be replaced after three to four years of service regardless of tread depth or tire appearance.
Mileage
Trailer tires are not designed to wear out.
The life of a trailer tire is limited by time and duty cycles.
The mileage expectation of a trailer tire is 5,000 to 12,000 miles.
Why Use An "ST" Tire
"ST" tires feature materials and construction to meet the higher load requirements and demands of trailering.
The polyester cords are bigger than they would be for a comparable "P" or "LT" tire.
The steel cords have a larger diameter and greater tensile strength to meet the additional load requirements.
"ST" tire rubber compounds contain more chemicals to resist weather and ozone cracking.
Storage
The ideal storage for trailer tires is in a cool, dark garage at maximum inflation.
Use tire covers to protect the tires from direct sunlight.
Use thin plywood sections between the tire and the pavement.
For long term storage, put the trailer on blocks to take the weight off the tires. Then lower the air pressure and cover the tires to protect them from direct sunlight.
Maintenance
Clean the tires using mild soap and water.
Do not use tire-care products containing alcohol or petroleum distillates.
Inspect the tires for any cuts, snags, bulges or punctures.
Check the inflation before towing and again before the return trip.
Keys to Avoiding Trouble
Make sure your rig is equipped with the proper tires.
Maintain the tires meticulously.
Replace trailer tires every three to five years, whether they look like they're worn out or not.
Trailer Tire Warranty
The Carlisle trailer tire warranty applies to the original purchaser for three years from the date of purchase or until the tread depth reaches 3/32".
The OE (original equipment) warranty goes into effect at the time of the trailer purchase
