The spacesaver spare is a donut tire, only supposed to hit 50mph with it on.

I bought 18" OEM rims off eBay - $750 shipped, including TPM sensors (worth around $200). I didn't see any rims I liked on TR.

I saw the closeout LM-25, but wasn't sure of its ice performance. I'm in Oregon, and we get some nasty ice each year. Also was wanting to try something that isn't a RFT to see if the ride improves, might switch over the all seasons to non-RFT if it goes well.

It's tough to find much info on these - most of the reviews on TR are just, "I really like this tire!" And a lot of the more official comparisons are 2-3 years old.
