Towing

[DIRTCUTTER]

Ck30 hst bh I was given a set of new LT 235/75/R15. I want to put them on my tandem axle trailer but I dont know if they will carry the load. So far this year I used the trailer to move my CK30 3 times no more than 150 miles round trip. Each tire is rated at 1800 lbs load range C. What do you think ? The tires I have on now are ST 225/75/R15 but need to be replaced.

would think lt's should be good for more than 1800lbs each

My 3/4 ton has LT's and I've carried more than 3000lbs payload alone, not including the weight of the truck with absolutely no issues whats so ever.

You've got 5000 lbs of tractor with bh and probably around 2000 lbs of trailer. At 7000+ lbs, if really rated at 1800, I'd say they would just be enough (assuming tandems). But if your're using a 10k lb trailer, I think they are not rated high enough.

Don't know a lot about tires and trailers but trailer tires usually have more sidewall belts than regular car and light truck tires which is better for weight carrying. Also the strengthen sidewalls result in less swaying of the tire under load. Just my two cents.

This is one area I wouldn't skimp on. You are towing a heavy load. You didn't say what the trailer capacity was but it is probably either a 7000 pound or 10000 pound trailer. If it is a 7000 you have (barely) enough load capacity in the new tires. If it is a 10K trailer, I wouldn't use them. Either way, most people only get to have one wipe out towing 7000+ pounds, so it is best to avoid it at all cost. Don't skimp with your safety.

Good point on the tire ply. My trailer is 18000 pound rated, each tire has a load rating of about 3300 (tri-axle), they are 14 ply.

I think LT means light truck not large trailer.

Hi,
You will want an 8 ply rated tire if you have a tandem axle trailer. The problem is the sway in the sidewalls as well as the weight capacity. When you are cornering or hitting a pot hole the weight is highly exagerated.
If it were me I would not use anything less than an 8 ply rated tire.
Be safe! I have seen trailers flip full size pickup trucks on several occasions from tire failure.

If you are loading that tracor onto a 7k rated trailer then you are overloading the trailer, and its axles, so no need to worry about the tires. If on a 10k rated trailer then you would be wise to use tires that are rated to carry at least 2500 lbs each to get the 10k rating and this is very possible with your LT tires. It all depends on the load rating. You can buy LT tires with a load range E that are more than adequate.

I use a 10k rated trailer, empty weight is 2500#, tandem 5200 lb dexter axles, and LR E tires (10 ply), for my CK30 without a backhoe and it is great. My tires are trailer tires and not LT tires but the key info is the load rating which is stamped on the sidewall.

Big difference between LR C tires and LR E even though both are LT.

No problem with using adequate LT tires instead of trailer specific tires. The RV world has blown that myth out of the water.

This is fairly easy. You have 7200 lbs of load capacity in your properly inflated tires. Subtract that from your gross trailer weight. The remainder is your minimum tongue weight.

That means for a 7,500 lb trailer loaded to the gills, you have to have at least 300 lbs of tongue weight to be within spec and legal.

???? Mis typed?

The tires are only one link in the chain. Where does the tongue weight issue come into this?

 

[Steve_Miller]

I interpret (and this is only me thinking) that he means in theory that for example you put 7500lbs on the trailer and situate it so that 300lbs of that weight is transferred to the tongue (tow vehicle) that in essence means you only have 7200lbs on the trailer which is the rating of the tires originally mentioned. In theory although highly impractical you could put 10000lbs on the trailer and situate it that 3000lbs of that weight was on the tongue and you would not be overloading the trailer until you jumped in the truck and started to move.

I thought he was saying the tongue weight does reduce the tire load. I wouldn't push it to within a few hundred pounds of their limit. Too many bad things can happen if you have a flat on a trailer hauling 5000+ lbs of cargo.
