265/70R17: 31.61" tall.
245/75R16: 30.47" tall.
Well done, GM.

makes no sense to say this 17" tire needs 35 but another exact same 17" needs 30
over a 54lbs payload difference
god forbid you overload it which is pretty easy to do with a 7 passenger vehicle plus cargo area
but hey that 16" should stay the same lol

Which is why I bought an extra alloy wheel and have a full size spare.

I should also mention I have tire pressure set at 36 PSI as I found the stock 30 PSI far to soft with OEM wheels and near OEM tire size...

Almost exactly what every police dept does with their tire pressures.

Can't go wrong with 35 PSI. For an 18" wheel the factory recommendation is 32 or 33 PSI I believe. In order to receive the full and maximum weight rating of the tire it must be inflated to the sidewall listed pressure, so it depends on what you are hauling or towing if you need to inflate to the maximum listed pressure or not.

There's a good bit amount of bad information in this thread. You should basically never use the max sidewall pressure unless you are also at max payload. If you can't feel the difference between 51psi and 35psi -- I'm jealous of your smooth roads. 10-20% over recommended will help in steering feel, but if you're driving these boats I'm not sure if that's worth pursuing.
If you're using a non-oem sized tire, you can use this to figure out what pressures to run as a starting point: https://tiresize.com/pressure-calculator/

How does one know what their payload is? If towing heavy, isn't the "fail-save" to inflate to max pressure rather than be under inflated and experience a catastrophic tire failure?
