How do you know if a 78 Spare is safe...

Wow I've worked at a Tire shop for a long time and I can say I've never seen anything like that. Was it the Collapsible type spare or a full spare?

 

 

Collapsible type. If anyone has one, it is probably a good idea to inflate and let it sit for a few days and check. I've not found one yet that doesn't split.

 

 

On a side note, has anyone found a full size 14" tire that will clear fitting in the small 76-78 tire well?

I would not inflate it "just to check"... You inflate it, your one day spare is then ruined.

 

Every one of these I have inflated has done this from 75-83...

 

I use them as rollers around the yard. The rims are identical to the standard ones on the car except for the nylon "quick dump" button fitting on the side to quickly dump air out of the tire after use.

 

They were NEVER intended to be used for more than a few miles, much less a month! It reveals why manufacturers don't use a folding tire on full size conventional rim anymore though, doesn't it? Now you get a T-Rated C-80 14 if that!

Peel off the rubber and take it land speed racing! Nothing left to be affected by centrifugal forces!

Seriously, our LSR tires look like the undercording on the inflatable spare... Not a lot of rubber on them.

 

Those spares must be closet high-speed racer economy slicks!
