987 Boxster 18" Wheel Questions

[husker boxster]

Hi Vince,

Let's start with Q#2 first. The sensors are probably interchangable but your better option is to buy a set from Tire Rack or your favorite discount Porsche dealer (Suncoast or Sunset). You can get a set for just over $400. Then you don't have to worry about a tire tech messing one up trying to pry it out of one of your 19s.

Now for Q#1. I have my 18" snows mounted on a set of Cayman wheels. I put sensors in them. When you put them on, the TPMS asks you if you've got 18s or 19s. When you enter 18, it tells you what the pressures should be for 18s (26F / 33R).
