I've gone back in time and went through my records.
At best my temporary spare was used for some 1600 km - 1000 miles - yet it's almost worn down to the limit.
(That was one additional reason to throw it out of the car.)
But it was used at the load it is intended for - underneath a 3300 lbs car at around 63 mph tops.
I wouldn't think of using 2 of them on my car, far less the four that some brave soul tested
Using them at far lower weights will likely help improve their lifespan, but how many miles did you do in those 10 years ?
