Funny, the minispare for a mirage has a higher load rating by 200lbs than the stock dunlop. And has 2 ply sidewalls when the dunlop having 1.
I did some work for an skip the dishes driver. He drove on his spare for weeks before it worn out completely wore out. I was as impressed with how long the tire lasted as much as I was unimpressed at the fact someone lacked the common sense to get a new tire sooner.
