Hello there guys and gals. Been awhile since I have been on here. Needing some help. I am currently going though the old Flareside to get it better setup for towing the New Cargo trailer I just bought. One thing on the list is load range E tires as the C rated ones I have now are just to soft. I am having trouble finding load range E tires for a 15" wheel. I am starting to think they don't make them. I just want to see if any of you know of some before I go and buy new wheels in a larger size.

 

As far as I know they do not make an E range 15". I could be wrong, but I've never heard of nor seen one.

 

If they do there might be one or two options and they'll be ridiculously priced.

 

How big/heavy is this trailer that you feel you need 10ply tires? To get them on this truck you will need 16" rims which will make the purchase more expensive and it's not really necessary for loads that a 1/2 ton can carry IMO.

 

E's will carry far more weight than your 150 is capable of. Try looking for a set of "D" spec tires, there may be some available for a 15" rim - at least there used to be.

 

The only Load E tires I know of in 15" are trailer tires

 

Ten ply tires dont give you 3x12 brakes, sway bars, stiffer springs, bigger U-joints or anything else that goes along with an increased gcvw rating.

If you feel you need more truck maybe the best idea is to get one.

 

Agreed. I have never seen anything else


Now if you changed your wheelss and went to 16" then that opens up a whole different world

 

I'm running C rated, 6 ply BFG 33x10.5 on 15" wheels. They're rated for 2600lbs each at 50psi. It's the highest load rating I've seen for tires on a 15" wheel. They work well for me, frequently haul 1200lbs on the flatbed in winter. The tires are definitely much more capable than the rest of the truck.

 

I might be able to help with 15" E rated tires. What size do you have or need?

 

Thanks for all of the replies. The trailer is not that heavy. My current tires are just about done and it will be time for new ones within the next month or 2. The Duratracs I have on were okay pulling it, but they were a little softer than I would like. Going to load range E is more of a preference than a necessity. I am not opposed to going up to 16" wheels at all. I was just wondering if anyone made load range E for 15's as my researching didn't come up with anything.

 

What do you mean by soft? They bulged too much? They squirmed under cornering or on rutted pavement while loaded?

How much air pressure do you run when loaded? How is your tire wear?

What, precisely, are you towing? Do you know the weight?

Your current tires are rated for 2200lbs each. That's certainly not exceptionally high, but not out of the realm.

Decent quality tires for your 15s should run you about 800 max. You'll drop 1000 bucks just for E range 16 inch tires, plus at least 200 more for wheels.

You can rent an F250 from U-Haul last I checked, for about 20 bucks a day plus miles. Will the heavier tires actually save you money over this option, if it can work for you?

Don't forget that, even if your trailer isn't that heavy, all the stuff you throw in the bed adds up too. Your trailer may only add 250 lbs of tongue weight, but the 500 lbs of tools and box, and probably trash and sticks, does its part too.

 

I can feel the rear tires getting squirmy in corners. I run them at 40 psi but did try 45 but it didnt seem to help. Tire wear is even, but down to 5/32. The truck also has new busings in the rear leafs. With It loaded the way I intend to use it it he trailer weighed in at just over 5800lbs with a touch over 500lbs tongue. All that's in the bed while towing is four 5 gallon fuel cans.

 

What's the gcvw rating of your truck??


Get some D rated tires and run them at 65psi.
Get a heavy sway bar for the rear.

My 16" E rated tires cost $127 each.
I mount and balance them myself.

 

I've heard the Duratrac is squirmy with lots of weight. Some guys hate them on diesel trucks when towing/hauling bc of it. It also seems everyone has a different idea of what is acceptable as far as side wall flexibility and tread block stability. Considering the Duratrac winter traction, I imagine they're very soft. When I was upgrading tires, 16" wheels seemed the only real option to get above 6 ply and still have a decent amount of choice on the tires, but I never saw E range in 15", and only a couple D IIRC.
