Is there a light truck tire with a max working load of more than 2050 lbs? I have 15" 7.5 rims and I'd like to find tires to fit these that have a load rating greater than 2050 lbs.
For 15", I haven't seen anything over 6 ply (load range C) but bigger tires (i.e. 33x12.50) has higher load ratings. There are actually quite a few that go up to around 2200 - 2300 lbs. Several sizes such as 31x10.50 in the Wrangler Silent Armor, for instance.

For a smaller size tire, like a 235/75R15 for example, it's going to be hard to find one with a higher rating than 2050 lbs because these tires are usually found on 1/2 ton trucks and some cars, therefore high weight capacity isn't really important because the 2050 lb rating will overload a 1/2 ton truck anyway... so why should the manufactures make one with even a higher rating?
The Goodyear Wrangler AT/S has a capacity of 2,335 @ 65 PSI, which would ride horribly rough.
I want them as small as resonably possible. They are going on the stock rims of my 93 f150.
31x10.50 should fit a stock rim.
Alternatively, you can temporarily overinflate your rear tires by by 5 psi (unless they show signs of distress), or get a 16" wheel to be able to use D or E rated tires.
I really want a small tire capable of holding the weight safely. I guess I'll have to invest in some 15 inch TR style rims. They have a different bead style designed for higher PSI I assume. Anyway, they allow for tires with load ratings of almost 6000 lbs. I hope they aren't expensive.
Your 2000lb capacity tires are capable of supporting your vehicle's GVWR of around 6000lbs....so there is no need to increase the tire strength.
I want a tire that I won't be running so close to its maximum load. I think I'll worry less about blowing out a tire. I plan on hauling a 3000 lb payload for some distance on the occassion and that would put each tire close to its max load when cornering or driving over rough road. I was looking into whether or not a load e tire would wear better than something less at that weight.
Since you may switch rims, why not buy some 16" rims? Many 16" tires have a higher weight rating than 15" tires.
I know it's only an inch difference, but I'm putting a flat bed on my truck and do not want to build wheel wells into the flat bed. Even 16" rims may not create a problem in this situation, but 15" rims will give me the better gearing ratio for hauling I think.
Those factors are taken into account when the tire is rated.
They will safely carry what your vehicle is capable of carrying.
A 3000lb payload in the bed is way over what your vehicle is capable of carrying.
You're able to carry about 1000-1300 lbs in the bed, by law...as well as just what the vehicle is capable of anyway.
The GVWR of an F-150 is about 6200lbs...give or take a few. Your truck weighs about 5000lbs give or take...you're truck is rated for weighing 6200ish lbs at it's max capacity. Which means you're able to carry about 1000-1300 lbs.
My F-250 is a lot beefier than my F-150 and it's GVWR is 8600 lbs. It weighs 5200 lbs. So I can put more in that truck...but it's made for it.
15" or 16" - they don't have an affect on the gearing. The tire diameter is what affects the final gear ratio. You might move up to a 30" diameter tire instead of a 29" diameter tire...but that will not affect your final gear ratio enough to matter.

Why am I limited to a half ton? I thought you are limited to carrying as much as you are registered to carry. Plus, it's not as if they take time to check to see if you are 1000 lbs over.
I understand what your saying about the tire and wheel size, but what about the wear issue? It seems that an underloaded tire will have a longer life and less friction than a severly loaded tire.
