I’d like to get confirmation on this. First, I am very limited on my knowledge of tires, towing etc.
A little bit of this because I was looking at two very different tires— one with a SL load range and the other with an E rated load range.
The difference could be a 50 lb total weight on the truck. And this would be on a platinum hybrid already low in payload value.
So will this actually reduce the payload by 50 lbs?

I have been told yes and no on threads in the past. Reasons varied but to me it would seem any weight added to the truck wherever it’s located should reduce payload. I’d like answers with reasons why, not just yes or no LOL
Also I have seen somewhere a payload list by Ford showing how different options affect payload, such as pano roof 64 lbs, FX4 package etc. On this list there were values for 18” wheels, 20” wheels.
Some were negative values, and the 20” wheels had like a positive value— 20-30 lbs- can’t remember exactly but I remember it was significant.
So this was included on Fords F150 payload option value list (can’t find it— maybe on some Adobe list somewhere) so it made me feel that wheels/tires do indeed have an affect on payload.
Any other confirmations?

 

I think Rick answered it best in your other thread. The Platinum is already going to be heavy and the added tire weight isn't going to be the determining factor for towing.

 

Unsprung weight won't reduce payload in practice on an F150.

 

This Google search shows why payload is decreased.

 

Why not? If the truck weights 5,000 with OEM tires and the tire tires weight 20lbs more per wheel and the truck now weighs 5080, how does not not go against how much the truck weights.

Of course it's so minimal it won't matter, but why would it not be considered a heavier vehicle in this configuration?

 

If you're worried that 100 lbs or less is going to mess up payload you have the wrong truck.

 

agree 100%
but out of curiosity is the tire weight the only factor? I’m wondering if the increase in rotation mass would also hinder payload.

 

not even sure what or if I tow. But since you brought it up, payload will indeed be a limited quantity on my truck. So actually, 100lbs of payload would be significant on this truck. Wouldn’t an additional 100 lbs of payload be worth 1000-1300 lbs of cargo on a trailer? Correct me if I’m wrong — I’m still learning.

btw— the primary purpose for this thread was about tires. Not really about payload although I questioned if that would affect payload. And then did a Google search to answer the question.I just brought up the potential if I moved up the load of the tire , it would increase the weight. I was questioning the need to even increase my load, and the first reply suggested the original OEM tire was fine.

 

It's unsprung weight, it won't affect payload per se. Unsprung meaning it's weight that is not carried by the suspension. Adding unsprung weight will have negative effects on fuel economy, power and braking because you are trying to accelerate and decelerate a larger mass, say a 50lb tire vs a 40lb tire. The heavier the wheel/tire the more energy you will need to expend to get that mass moving or stopped.

As far as tow ratings and payload capacity, that can change with different load range tires, SL vs E rated for example. E rated will have a higher load rating at higher inflation pressures. Ford typically equips their trucks with P-metric (SL load) tires, which if you look up the specs, you'll see that the load rating of even SL tires will exceed your max payload. Heavier E rated are built tougher and with more plies to take the added weight of more payload/heavy towing requirements. Honestly you'll rarely need an E rated tire on a half ton for towing. They will behave better and handle the weight better while towing but will be heavier, harsher and not as comfortable when not towing.

 

Nope. Payload is not realted to power loss. Payload means nothing more than the total amount the truck can weigh. The Gross minus vehicle weight equal payload. Take the gross 7,000 max truck (or 7050), subtract the 5200lb truck, subtract the extra 100lb tires and you have remaining payload. Of course keeping with the cycle, subtract the weight of the bed liner, tonneau cover, light bar, etc.

But yes, the weight of tires being the culprit of going over max means other decisions were not properly made to get to this point.

A person could replace the aluminum wheels with heavier steel wheels, same tire as OEM and payload technically would still be altered because the wheel weight has increased.

Neither the tire weight or theoretical wheel weight is going to hinder the choice of trailer being towed. Power will be reduced but we all know that and none of care because we want the taller tire and are okay with any performance hits it may or may not have. At least a person could carry the same weight trailer and driver slower due to no power (worst case and exaggerated scenario).
