Wow, sounds like a nightmare of a ride home. Glad to hear that you made it safely.
I do not live anywhere in the area of the tire you are looking for. But I do have a question. If someone does find your tire would you actually drive the 4 hours there and 4 hours back home again for it? Just wondering but with gas prices so high would it not be cheaper to just find a good used tire if a new one is to expensive and put that on instead? I know we have a great place where I live that sells used tires so that is what made me wonder if that may not be an easier option for you.
