Figuring max payload / impact of changing rims and tires

Wife has a little project in mind which will require a bunch of patio pavers. I never thought about payload and my truck capacity much before since I don't haul that much weight generally, but when I calculated the weight of the pavers we would need it added up to roughly 2,000 lbs (not including paver base stone and sand, plus my wife and I), I became interested.

My 4x4 Crewmax has a payload of roughly 1560 lbs based on factory info. I have not looked at the sticker inside the door, just found this info onToyota's website specs. HOWEVER... I believe those specs (and the ones listed on door sticker) are based on the base factory rim/tire, correct? If so, my question is how would I figure max payload for different rim/rire configurations? Mine was delivered with 20" rims and Duratrac AT's as part of the TSSOR SE package, which I assume will have a different weight carrying capacity than the standard rim/tire?

I know the paver job greatly exceeds my capacity no matter what, but it piqued my interest when I started thinking about it and now I'm curious how to figure my max capacity as the truck sits, and as future mods take place.

 

Max payload will be unique to each truck due to options with the 4x4 Crewmax Platinum and 1794's having the least payload from what i've seen so it's best to check your door sticker. There might be another sticker that is yellow that has the extra weight reduction of port or dealer installed options and this must be subtracted from the max cargo weight on the original sticker. If those are the original wheels/tires that the truck came with from the dealership the weight of them should be reflected on one of those stickers.

 

Check your door sticker and I think you will see it’s much lower than 1560 lbs. Different/heavier tires will lower it more. Best option is to go weigh the truck and subtract that from the gvwr, usually 7200lbs.

You’ll definitely be making more than 1 trip.

When I weighed my truck, it was around 6800 lbs. I only have 400 lbs payload. I have a cap and decked drawers loaded with stuff. Payload is my only buyers remorse and is why I’ll get a 1 ton truck next time.

 

I didn't realize they would put a 2nd sticker after port installed options. I will definitely check for that. Not sure I'll make the effort to weigh the truck, but I definitely see the point if I add a lot of additional permanent or semi-permanent gear.

Thanks for the info!

 

Get a trailer to make one load

 

Changing your wheels and tires will only reduce your payload, unless you added lighter weight wheels and tires. To be safe You should just assume payload isn't based off of your tires load capacity, so you are never going to gain payload.

 

I put a pallet of pavers in back of mine without issues.

 

Going over payload is kind of abuse. I would rent a u-Haul trailer if you don’t want to make several trips.

 

10ply tires are rated for substantially more weight then a OEM P-metric 4 ply tire. So yes your payload capability would would be improved by a 10 ply tire. However whatever the manufacture set the payload rating at on your door sticker, is not going to change.

You would however notice a much more stable ride if hauling at the upper weight limits , if you have a load range E / 10ply tire vs the OEM tire.

Tire load range ratings is part of what comes into play when the factory sets its payload ratings. Some manufactures FORD IE. offers some upgraded load range tires on some of their F150s which does increase the trucks payload ratings.
