Trailer tires

[Red Rex]

What rating tires do I need for my trailer?

16 ‘ x 6.5’ rated for 7000 lbs GVW
2 axle trailer is 2000 lbs leaving 5000 lbs for cargo.

I use it to transport my 1968 Ford 4000 tractor or1968 Massey Ferguson 135 tractor. The Ford is 4850 lbs so yes I do push it but transport rarely exceeds 55 mph.

What size wheels and tires? I'm a big fan of heavy ply tires on trailers. Squishy tires tend to sway and wear out much faster.

15 “ wheels. Current tires are
F78 15 load range C

4 ply tread 2 ply side wall.

I blew one out yesterday towing the Ford. I had the tractor loaded more towards the front and about 3” more to the right than center. The rear wheels just slightly forward of the centerline between the 2 axles so that might have put a little more loading on the right front tire. All tires were inflated to max.

appreciate the reply!

They make "trailer only" tires. Carlile, maybe? It's a heavy bias ply, a hard stand up kind of tire. Generally cheaper than a 15 inch truck tire. Had a set on my 20 by 6' 8 trailer for years. Hauled a 480 C Case backhoe quite a bit with never an issue.

I have an open16 foot car trailer, an enclosed 26 foot and an enclosed 24 foot and all have load range "E" , 10 ply radials. 2 have Carlisle and the bigger enclosed has an off brand , I don't remember which, but it just made a trip from Weiser ID to Marshall MO and back successfully. If I remember correctly, both of the enclosed have 215/75R15 and the open has 205/75R15, but they are ALL 10 ply. Not cheap, but what is your load worth??

The only vehicle we have that does not get load range E is the wife’s Midget.

I'm going echo what others have said, get more tire than you need. Stiff is good, less sway. E-rated is great idea. I'll also add that radials are preferred even if you currently have bias plies. A few good reasons to run radials. Lower failure rate, as in fewer tread separations happen with radials. Bias plies tend to have a lot of rolling resistance because of the way they splat out on the road as they roll along. Radials don't do that and will provide less rolling resistance.

F78-15 would be a ST205/75R15. A load range D would have a 2150lb rating per tire. It has a 27" height. If u have enough room the next size would be a ST225/75R15. It is 28.1" tall and is rated at 2830lbs in an E range.I use Carlisle Radial Trail HD Tires for my trailers.

I used two 10 ply 2655516 or whatever the size on my truck bed trailer because I accidentally bid on them In an auction and won. I took the 2 best of the four. Free a year I need a new set, one has a slit and a bulge. It’s only 8 years old. Handles well on the trailer. Impressed.

definitely recommend stiff side wall.
The alloy 6 lugs I got with the wheels I have no use for which is sad but That’s ok

ST 225-75-15 D or E load range is what you need.

I just purchased 8 of the 10 ply "rated" E weight range, Carlisle tires earlier this spring for my camper and boat (with spares). I had 2 china bomb tires blow on my boat last year within 5 days of one another. Only 2 years old, less than 2,000 miles. I don't want to chance a blowout on the camper, so I replaced all of my trailer tires with the Carlisles, and don't regret it one bit.

Make sure they are special trailer(st) tires. You can run regular auto tires on a trailer, but they are not nearly as strong and will sway more for a given weight rating.

And a trailer tread will also track nicer with the tread design than especially at tread

The tread is more meant to let the tire run cooler at a heavy load and less to provide traction in wet conditions like an automotive tire. The nicer track comes from the stiffer sidewalls and the lateral stability from the way the cords are laid down.

Yes. You have the knowledge. I can’t wait to get new tires on my truck Ned trailer to see how much of an improvement over old stiff 10 ply at truck tires it makes

I’m looking at that tire
