Re: heavy duty light truck tires

BF Goodrich makes a 285/75R16 in LR E with a 3750# rating at 80 psi.

Are you carrying all the weight on the truck? 4 of those tires make a 15000# truck, which is pretty heavy for a single wheel truck.

To get any heavier than that, you will have to go to 19.5 or 22.5" tires to get rims that will handle the weight.

Re: heavy duty light truck tires

The BFGoodrich AllTerrain tire with 3,750 weight capacity will let you put up to 7,500 pounds on your rear axle that has a limit of 6,084 pounds. Or if you are a believer that Ford really put a rear axle rated at 6,830 pounds in your F-250, that's still a lot less than the 7,500 pounds tire limit with ordinary LT285/75R16E tires.

If you insist on overloading your rear axle, then you should be taken out and shot at sunrise. Endangering my grandkids on the road is not a good idea. [img]/ubbthreads/images/graemlins/frown.gif[/img]

My Sierra Blanca (Spanish for White Mountain) in the sig pic was a great pickup for 11.5 years. I sold it several years ago. I drove a hand-me-down 2003 F-150 SuperCrew 4.6L 2V for a while, but it was unacceptable for towing more than a rowboat. Replacement is a 2012 F-150 EcoBoost SuperCrew Lariat that tows my 5,000-pound TT like a dream. Replaced the 2012 with a 2019 F-150 3.5L EcoBoost with max tow.

Re: heavy duty light truck tires

I think you may be over estimating the tire load. Your truck probably weighs in somewhere between 8 and 9K. What's a quad, 600 pounds?

And figure your trailering another 9K, figure 1K of tongue weight (just over 10%).

With those rough figures you're looking at 10,600 on the axles. Divide by 4 and you need 2650# per tire capacity. Either a 33" or 35" (305/70 or 315/75) would handle that no problem, and be wide enough for flotation on sand.

If your trailer weight is substantially heavier than my guestimate then you have another problem, any trailer over 10K requires a Class A CDL.

Re: heavy duty light truck tires

For California:

A Noncommercial Class A license is required if you tow:

a travel trailer weighing over 10,000 lbs. Gross Vehicle Weight Rating (GVWR) which is not used for hire.
a fifth-wheel travel trailer weighting over 15,000 lbs. GVWR which is not used for hire.
a livestock trailer that is not for hire, weight over 10,000 lbs. GVWR but not over 15,000 lbs. GVWR, and is operated within 150 miles of the farm by a farmer to transport livestock.

There was also a RV endorsement on a Class C for fifth wheels between 10,000 lbs and 15,000 lbs, can't seem to find that mentioned anymore.

Re: heavy duty light truck tires

dude move up to a 350. you are throwing good money over bad at a losing propostion. unsafe is unsafe. do it the right way. if you dont want the lb get a sb f350 they do make em. or just get a dedicatied tow rig. 95-97 cc dually are cheap enough. you have plenty of toys and a lot of money in them. flipping it all over you will never recover your investment from your insurance if you were knowingly and purposely overloaded. and yes they will find out you knew that you were purposely overloaded. i have been overloaded too so i moved up in truck. sometimes i am overloaded on that truck and trailer too and i unload some cargo. your insurance company WILL deny your claim if you overload any part of your equation all the way down to your ball. (pun intended).

Re: heavy duty light truck tires

air bags will only keep your truck from sagging. but if you put too much weight on the back it will transfer weight off of the front causing possible control probs. air bags say they increase carrying capacity by 5k pounds or whatever. you cannot increase your trucks carrying capacity. only adjust its stance. but as i stated you need to watch weight distribution and not take weight off of front axle.

Get a grip Smokey. Speed kills lots more folks than weight. Go to any livestock auction and you'll see lots of 3/4 tons of all brands pulling 24' stock trailers that when loaded tight will weigh 17 - 18000 pounds. Most are running the stock tires Ford gave them and the trailers are putting 3500-4000 pounds on the rear axle of the truck with no adverse issues.

Re: heavy duty light truck tires

Let's rephrase, you need a dual wheel truck (since there are single wheel F-350's). A long wheelbase F-Superduty would be even better.

I'm not talking about those "appearance only" dual wheel conversion kits, you need a truck that can handle the weight.

Same reason I got rid of my 1 ton wrecker, you can only stretch a truck's capacity so far.

Re: heavy duty light truck tires

Ag_Teacher,


Fighting a losing battle. It's easier to save your breath/ fingers...

But since you brought up the sale barn.

How about getting passed up by a 1 ton dodge, pulling a 40 x 6'8" with 4 axles, yes 4. Btw, this is a loaded truck, looked to be packed full of yearlings. I cannot imagine the weight, but if I had to guess, I would say close to 45k
I know I can hit close 20k plus with my 24' pretty quick.

The axle weight rating of the truck (door jam sticker)is based upon the weakest link....I believe that would be the tires in your reference above - 6084lbs / 2 = 3042lbs - or the 265/75 & 235/85 tire wieght rating

I recall reading somewhere that the axle itself (rated my the manufacturer) is rated in the vacinity of 9000lbs. So if you are looking to see what components are the weakest link - I think the wheels would be next, then the springs - but not the axle......

I think the goodyear tires (for trailers???) are G rated over 4000lbs - but I don't think they are suitable for drive and steer axles....
