substitute tire size

[CLIFFTALL]

I have Michelin 235 80 xrv 22.5". I want to carry a spare but don't want to spend $400.00. What size if any do other mfg. make that would qualify for a get me to the tire store spare.

You could check at a tire shop that services trucks or a truck wrecking yard and get a used one that is enough for what you need.

Craig's list or ebay has bargains on them from time to time.

If you are in the Phoenix area, there is a tire 7 rim on craigslist.com
RV/Motorhome Tire& Rim 235/80R22.5

You could also look into other brands, but they will only be $50-$100 less than the Michelin. Try Toyo or Continental or Bridgestone.
