20" wheels to 17"

[Wylie_Tahoe]

Final chapter. I ordered the Schrader 21507 TPM's and got them installed today. They sync'd up so ive got my pressure readings back.

SO all-in, im inside of $200 + my time to swap the 8 wheels.

I did the same thing (other than aftermarket black rims for the 17").

For the benefit of future readers: check your spare tire size. My local Les Schwab was originally not suggesting the swap until they confirmed that my 2009 LT was supplied with an OEM 17" spare tire so unless the rim's built funky, the spare tire size will likely mirror the smallest rim size (at least in those vehicles that get spare tires and not "tire repair kits").

GMT900s are equipped with a 265-70-17 spare tire.

This is in regards to an earlier reply in this thread:

A P265-70-17 and P275-55-20 are functionally the same size tire height wise. GM considers them the same.

With one exception: application of snow chains
