Just picked up my first big trailer. A used 24' gooseneck to pull behind my pickup. I'm not such a noob that I wouldn't realize that load range "C" tires probably aren't going to hold up anything but a load of sailboat fuel. I'm happy they can hold the trailer up. Said trailer is rated for 24,000 lbs., sits on tandem.... either 12- or 14000 lb axles & currently sports 4 LT245/75R16 4 ply tires (is LT light truck??!) rated for 2200 lbs a piece. The heaviest load there is to haul with it is my chopper, which weighs in at 11,500. Should each tire be able to handle at least 1/2 of the total capacity of the trailer or how does that work? How many ply is required for this or does that automatically go up with the load range? The ones on my truck are load range "E", 6800 lb. capacity & are 10 ply, but I could have ordered the same sized tires at 8 ply.

Thanks,
Mike
 
I like lt rated tires on the trailer. Id get load range e there is no such thing as to heavy of tire on a trailer

Better check your numbers on that trailer. No way a 24,000# trailer will only have 4 tires. Axles are probably 7,000# each.
 
Whoops! My bad. You are correct, sir. 14,000 lbs is what it is.

With a 14000 pounds trailer your equipment is probably to heavy. Subtract the trailers weight from that 14k and your left with 9 or 10000 lbs of hauling capacity.

I'm guessing your trailer weighs around 5000 lbs empty... so you could carry a 9000 lb load with correct tires on the trailer minimum... Some factor in the load forward on to the truck a bit meaning you could carry around 10,000 again, with the correct truck and correct tires on the trailer.

I have stop putting e rated tires on my goosenecks and have moved f or g rated tires to help stop blowouts and tire separation problems. This way I can get my 6 years out of the tires and not have to fool with problems on the road. Yes, my rims are still rated for 80lbs even though the tires are rated for 110 lbs. I run them at 90lbs and never look back as I try to stay with in the design total load limits of the trailers, axles, and the pulling vehicle.

your c rated tires would limit the load on a typical 24 ft (5000lbs) gooseneck to around to around 2600 lbs load at best due to tire loading.
 
Hmmmm.... you have a point there. Now that I have the manual, I have an accurate total, 9987 lbs. It's 8510 for the chopper & 1477 for the head. May
be best to haul the chopper without the corn head. Would make for easier loading without that anyhow & it will keep my gravity down.

Mike
 
Ok.... I most likely am wrong so please correct me if I am. Besides the actual weight of the load, don't you have to throw in the weight into the gross load of both axles? Wingnut
 
If you keep the 16" wheels, you can use a Load Range G tire. They're available from Sailun and Hankook. If you want to move up to Load Range H tires, replace the wheels with 17.5-s. I moved away from E range tires a few years ago and have never looked back.
 
Good to know about running lower tire pressure with the higher rated tires. Have no clue what the rating is on the rims that are on there. They look
to be original to the trailer & may need to be changed out.

Mike
 
If you go with a tire that has ST on it that is a specialty trailer tire and has heavier sidewalls for turning so they don't roll under when you turn with a load
 
If you are going to put lots of miles on the trailer ignore this. If you are like me, I pull a trailer a lot, just not very far most of the time. Buy bias tires not radials. Mine are do to be replaced, but they have been on the trailer for 20 years. 7000# trailer with 8 ply Power Kings on it. I am lucky to get 4 years on the PU tires before they separate.
 
Don't get trailer tires, too many failures with them. Use let radial truck tires. If you have 7k axles you need tires rated at 3500lbs each to haul all the axles will. If it's a tandem with 7k axles it can only be rated at 20,000 gross weight. 14,000 for the axles plus 6,000 on the hitch. That will be minus the trailer weight to get max payload. If it's rated at 24,000 then it must have 9,000 pound axles and then you need expensive wheels and tires to get that load rating. That is why those are pretty rare, you can get a 10,000 pound axles with dual rims and tires for about the same cost. So most are either 7k or 10k axles. So look close at what you have and load accordingly.
 
From the picture you posted it looks like your trailer had 7.50x16 bias ply tires originally, likely they were 10 ply. So you should be using tires having at least that same rating on your axles, going with even higher load range tires is good advice. 14 ply tires were available, but likely would have been special order if it had those. It appears Calico is still in business, so you might call them and see if they can/will tell you what was on it when it left the factory to meet the rating.

235/80R16 load range E (10 ply) seems to be common on new trailers with 7K axles. That size appears to be a replacement for 7.50x16 as well.

One critical thing with trailer tires is to keep the tire pressure up to the spec pressure for load capacity shown on the side walls. I expect low air pressure is the leading cause of trailer tire failure. As the ply ratings get higher so do the required pressures, 100-110 psi is not uncommon in the higher ply tires.
 
The gooseneck trailer we used to have had 8 goodyear bias ply tires on it. Tandem dually. Last I seen it they were still on there. That trailer was at least as old as yours so these are really old tires ! So the advice of buying bias ply tires may be valid ,but I don't know if you can even find them ? When we bought it the dealer said with a gooseneck you can run full rating load on it as you can put a lot more weight transferred to the truck pulling it.
 
I've found bias plys & will have to research the pros & cons of running those later today. One thing that comes to mind, from past searching is, I can't put bias ply on my camper & pull it at the same speed as radials. The difference was 75 MPH for radial & 55 for bias. Didn't look to see if that improves if I get a heavier tire. Will have to look into that, too.

Mike
 
I'll have to get a hold of Calico. Never heard of them before, thought they might be a fly-by-nite company & never did a search. Will look into the 14
ply tires, as that's what's on my small crane & those need to be changed, too.

Mike
 
I had thought about truck tires. Was wondering if the extra tread, over what I've seen on trailer tires, won't cause some sort of problem when turning. Just thinking they might grip too much & cause a blowout, twist the axle, ect. Just like running "skis" on the front of a semi. They're great for turning & little else.

Mike
 
Good to know. I don't plan on making more than a few heavy, short hauls a year with it. Maybe a long haul if I really find a good deal on something out of state, but doubtful. Otherwise, it would be small square bale delivery.... & that wouldn't be too often either.

Mike
 
Yes sort of, but mainly they are just built cheaper and have a lower (65 mph) speed rating than a truck tire (75 mph+) due to said cheap construction.

Lower speed rating dramatically increases the load capacity rating for a given tire construction as you won't generate as much heat.
