Found a wheel for my spare. Got it off a totaled 2011 Dodge Ram 1500.
I also got 3 of 17x8 alloys from the same vehicle (the missing one was apparently destroyed in the same "incident" that totaled the Ram). I'm now looking for a matching fourth wheel. Once I have found it, the 17 inch alloys will be used for a set of winter tires. I'm currently hunting for a set of used winter tires with a couple of seasons worth of rubber left on them. Unlike provinces like Quebec, winter tires aren't required by law to be fitted here, so the use of winter tires is purely at the driver's discretion. I didn't run winter tires on the Durango, and found that the 265/65R17 summer tires made driving just a bit "unpleasant" on icy roads when the ABS and TC both went out due to a failed wheel speed sensor. We fitted studded tires to my wife's FWD car and the difference was amazing. Running studs on her car became much more important after the Durango had been totaled and we had to rely on her car in all weather conditions. Studded winter tires are allowed to be fitted from October 15 (4 days time), so that gives me more options in the used tire market. 245/70R17 or 265/65R17 tires both have the same rolling diameter as the 265/50R20 tires it came standard with, so that will allow me to use the same 245/70R17 spare in both seasons (although if I run studded tires in winter I am technically not permitted to fit an unstudded spare).
