I’m supposed to pick up our new travel trailer next month and am concerned about towing with only the donut spare tire. I know moderator Robert Mauro says he carries a full size spare deflated and it fits in the spare mount no problem. My question is trying to find a cheap rim to mount a spare tire on. I can’t find any plain steel 18” rims for an Ascent. The least expensive option I’ve seen is getting a used OEM premium wheel off EBay for around $185, and that’s minus a TPMS valve. Has anyone else found a cheaper solution to going this route, or is that my only option ?
