Snow tires 2

[husker boxster]

When I put my snows on my 08 CSS, it asks me winter or summer, then 18" or 19". I'm not sure if it knows rim diameter is currently 17", but an S wasn't meant to have 17", so maybe that's what's causing the issue? Since it wasn't programmed for 17, it doesn't know what to ask you. Just scatter shooting, not sure how it would know it was a 17" wheel on.

If it's showing pressures and you don't have the tpms tire light and red exclamation point lit up on your dash, you're miles ahead by not having any lights on.

Also, did you get longer lug bolts for those spacers? Using std bolts would be dangerous with those 15mm spacers.

The spacer came with longer bolts.

I'm thinking that it expects all the tires to be the same diameter. It's not a biggy, everything else works and the gps lets me know the right speed.
