snow tires

[lcsdoug]

I recently purchased a used set of wheels for my 987.1

6.5x17 et 55
pn# 987-362-112-06

and

8x17 et 40
pn# 987-362-126-01

I'm planning on getting Yokohama iceGUARD iG52
205/45/17 front
225/45/17 rear

The seller said not all the TPMS units may work so I'll replace
them as well.

Does this sound correct?
I won't be driving a lot in the snow, but it I may have to occasionally.
