Road trip smaller spare problem.
I'm about to head to Lake Superior where a blizzard just hammered with snow and the forecast is for brutal cold.
@MCtree generously gave me his winter tires from his Alaska trip and I have 4 of them mounted on the fugly candy apple red Fuel wheels that came with the truck. I got the truck with less than 10k miles on it but some kid put those red wheels and a snorkel on it and threw away the stock lug nuts. Fortunately, the truck came with the stock wheels and I put the Terra Ridge Grapplers on those. I tried to sell the red wheels with the tires and got no bites. Problem is I only have 5 stock wheels and 4 fugly red ones. Of course my spare is under the truck on a stock wheel. Now to the size difference.
The Ridge Grapplers are AT 285 65 18 and the Blizzak's are P275 65 18
Calculator difference is:

Question is: Do I throw the extra Blizzak unmounted in my trailer for the trip and hope I don't have a blowout? Can I run 50 miles with the larger Grappler spare until I can get to a place to mount and balance the Blizzak 5th tire?
Or do I have my spare dismounted and put a Blizzak on it for the tirp? I'm out mounting and balancing X2.
