Hello everyone,

Joined a few weeks back. Finally found time to post my payload question which is this. I bought a 2014 4x4 SCREW with the 5.0 after my 2008 was totaled. This truck originally came with 18' wheels, but when I bought it the dealership had the 2018 Ford 20's on it. How does having the larger than stock wheel affect my payload? I'm assuming it would go down, right? By how much is what I'm wanting to know. Would it just be the difference in weight between the 18' wheels and the 20' wheels? If it makes a difference it has the Hankook Dynapro atm 275/55/20 on it. I've searched, but was unable to find any information.

Thank y'all in advance.

 

I should think the rating of the new tires and wheels might be the limiting factor, not the weight of the new wheels. Good luck finding that info.

 

Theoretically the payload would go down as the engine/trans has to work harder to pull the same load with a "taller" wheel/tire combo. However, the 55 series 20 inch tires that you have on there now may not be all that much taller than the 75 series with 18 inch OEM wheels. Not sure I'd be too concerned but interested in what others think....

Nice looking truck btw...

 

Payload will only go down if new wheels and tires are heavier than the old ones. They are factory rims so they should have a high enough load rating so it's just the weight change if any. I wouldn't worry about it

 

Thank you. I'm not so much concerned as I never have to tow or carry payload anywhere near capacity. However, I'm detailed orientated which is a nice way of saying I'm **** and therefore just wanted to know the particulars. Thanks again

 

Never thought of this and now that you mentioned it I agree. Didn't think it could possibly be that simple. Makes sense though. Thanks.

 

Thank you.

 

To get an actual accurate answer you would have to go get the truck weighed anyway. By the time you fill up your console with crap / load tools / straps / etc into the truck, add box cover, blah blah blah.....that door sticker is just the 'max' lol

I know I have a couple hundred pounds of 'stuff' in my truck already.

 

Just for your info...

Original 275/65R18 tires are 32.07in. diameter.
Installed 275/55R20 tires are 31.91in. diameter.

A difference of about 0.5% very minute difference. I'd ignore it.

As for the PL difference, it is possible for different tires or wheels to limit your PL. But I think you'll be OK with just using the weight difference between stock and the installed wheel/tire.

 

Thank you for the information. Appreciate it.
