What are the OEM tires and OEM tire size that comes on the X with the 17" 7-spoke rims??

My tires have been changed and i think the previous owner used the full size spare and put one of the one wheels in the trunk as my TPMS light is on. It's driving me nuts to figure out which one was the spare.


Right now i have Goodyear Eagle RS-A's and i know they are terrible in the snow. I want to put some Blizzak's on for winter and want to get the right size as well as figure out which wheel was my spare so i can put it back in the trunk.

From the looks of the valve stem, my full size spare also has a TPMS sensor on it. But i only though 4 sensors were tied to the vehicle at a time

 

My 06x came with Goodyear RS-A 215/55/17 (and yes, they suck)

I replaced them with 235/50/17 (same overall diameter, 20mm wider) Goodyear Eagle F1 All Seasons (and yes, they rock)

 

Ok that helps out a lot actually. Looks like my PO had to replace the tires as the one in the spare was worn.

I did some research and it seems these tires wear out around 20K miles, which makes sense as i have 26K and a fresh set of tires.

They suck. I am going to put snow tires on them however, and in the spring buy a set of 18" sport wheels or 19" coupe wheels.

I just need to figure out which wheel was the spare by seeing which is the cleanest rim
