Driving on a temp spare?
Ok, Ive been searching around and have seen all the "skull and crossbones" warnings about using temporary spare tires beyond their intended limits.
Here is my dillemma:
The trike im building, will use a motorcycle rear wheel, and the one I want to use, form a rebel 250 is only 2.5" across x 15" I could go with a magna wheel which still is only 3" wide.
No such thing as a car tire I can find that narrow.. (anybody know of any?)
There are plenty of 125/80/15s littering the junkyards in the backs of cars as space saver spares though, $5 buys them all day long.
What I am really interested to know is if anyone out there is driving on them either out of nessissity (no dough for new tires) or as a hypermiling maneuver after the listed 100 miles do they in fact self destruct?
Or is the service life warning more in line with "dont drive your car too far with a tire that isnt matched diameter wise with the others" or "Dont drive too far with your 3000 pound car on these tiny tires"
(I would be using one on the rear on a 1000lb (with people) trike)
Any input?
Thanks
