The 16" wheels use the larger sized rotor.

You need to get what matches what is on your truck currently. That is probably whatever was on the truck from the factory (don't trust the door sticker, they almost all say 15" wheels/tires).
The calipers, pads and rotors are all different between the 15" and 16" wheel trucks and they all have to be changed together if you are upgrading.
(and really, you don't want the 15" wheel brakes on a 16" wheel truck... they are way underpowered with the larger tires)

Pretty sure you don't change your brakes if you change wheel size. That would mean that every time you buy a wheel upgrade you have to upgrade your brakes? Makes no sense

You only need to change rotor/caliper size if you are going SMALLER, not larger. Reason being is the 15" wheels came with the smaller rotors and calipers so if you tried to put a 16" wheel on those trucks, the rim wouldn't fit over the caliper. But those 15" wheels usually only came on the base model trucks.

Yeah I know about that. I was kind of being sarcastic because someone said you need to change your brakes when you get bigger wheels. haha

I have 17's on my truck and she stops just fine. Will be doing the tundra brake upgrade when I have the cash
I think he was saying our brakes are already a bit underpowered so going to the smaller ones just because it's cheaper would be a bad move. But to the OP, it owuldn't be cheaper because you'd have to change calipers. If your truck has 16" wheels you need the larger rotors.

Uh, the 15" wheel trucks came with 225/75-15 tires, or 28.3" diameter tires. 16" wheel trucks came with 265/70-16 tires, or 30.6" diameter tires. The smaller brakes on the 15" wheel trucks match the smaller diameter of the tires that the truck is spec'd to come with (8% difference in tire diameter, 7% difference in brake rotor diameter).
It was a bit shorthand, but when I meant 'changing to 16" wheels' I meant upgrading the tire size along with it. Then, often at the same time, guys will go with 265/75-16's, or 31.6" tires. That's a 12% reduction in braking force... on a truck that was under-braked in the first place.
