Time for some tires on our stock trailer. every trailer Ive had came with radial passenger tires it seems. I read where its a no no due to sidewall strength etc, And reccomended is a bias ply tire. The trailer loaded wont exceed 7K, I was thinking of taking the 31x10.50x15s lts off the jeep and putting them on the trailer.they are load range C which says I think 2850lbs each. The tire are new.
Is this a bad idea with a taller tire which might increase sidewall flex?
Thanks all.

 

I would say No. I've seen (passenger/truck) tire sidewalls when they've been ran on trailers, scary. I've been taught that technically trailers do not have suspensions (bouncing) on them and thats why they need the re-inforced sidewalls. It also reduces swaying. Just my $.02

 

AG? were neighbors. I work in oceano.Rig sounds nice, dont belive Ive seen it around yet. Your right I forgot about the suspension issue. Ours is tortion type and not much at that.

 

Cool! Were abouts in Oceano Neighbor? If you havin seen my Rig you've probably "Heard" it.

 

Most trailers have Dexter Axles & Spings, not much differrent than the rear of our trucks. Shocks can be mounted to the trailers, Monroe makes after market kits for that. I think the tires are OK, but may be subject to early failure if you jacknife the trailer much, putting strain on the sidewalls. There are specific trailer tires (ST?) that are designed for their differrent requirements, either bias or radial.

 

supr, i think he's talking about BIG closed car trailers, they have a torsion axle so that the load floor can be lower.

i 'think' the leaf spring & axle are used on open trailers & most small trailers.

this is a good thread, what about using car rims on a trailer?
my trailer has white wagon wheels, lookin crusty

 

Goodyear has a new RST, radial special trailer that looks very good. I just put a set on my fiver. G rating, 14 ply all steel. Tough looking tire.

 

I finally broke down and bought 4 ST rated tires, 8ply. Least I have piece of mind now.Sometimes it dosent pay to be a tightwad like me

 

When you get into 16" trailer tires and above, you'll find that most tires recommended for trailer service carry an LT designation. Examples?

We ran Michelin XPS Ribs (LT235/85R-16E) on our previous 5th wheel - load range E, 3042 lbs per tire @ 80 PSIG. These all-steel radials are recommended by Michelin for commercial trailer service and have solved a lot of 5th wheel owners' tread separation problems that were experienced with OEM fabric-and-steel radials.

Our current 5th wheel (see signature) came with Goodyear G614R/ST all-steel construction radials designated as LT235/85R-16G - load range G, 3750 lbs per tire @ 110 PSIG. This tire, despite its LT designation, is designed specifically for trailer service.

So, not all trailer tires are designated ST.
