New Spare Tire Available (Page 2/3)
theogre DEC 06, 11:32 PM
"Expiration date" is 6 years after date code in most doc's and web sites including NHTSA site.

Many vendors and manufacturer will destroy unsold new tires in less then that for several reasons.

Unsold and unmounted tires still "rot" from crap in the air, more so in most shops and warehouses allows oil and other fumes, dirt, etc, getting to the inventory.

Mounted then 99+% will have wet oily and otherwise polluted air use to keep up inflation and "rot" inside out so Spares may look new outside and still be bad.
Even when compressor has no oil in it often still output wet polluted air.
Plus spare tires under stress holding 60 PSI (~ 4 Bars) 24/7 for 10+ years mean isn't just Fiero needed new spares.

Instead of fill 60psi every month... keep small cheap compressor. Then when you need the spare, can inflate to 60 w/o risk of belt fail or worse.
Any tire under a few % of "full" of door frame sticker are "Running Flat." When you see a tire is low by looking, tire has a short life or is "dead" even after filling.
"Running flat" starts happening at higher pressure these tires so running 40-50PSI can easily destroy them.

I will vote for " blew apart sitting in the frunk" on this one. I have seen an identical failure as the original post, and it was not due to driving on the tire underinflated. It was a mid-90's Saturn a friend recently purchased. The spare had no air, so he aired it up. About a month later he had a flat, went to retrieve the spare, and it looked just like this tire. Theory is the tire had been in the car for so long with no pressure, the tread rubber took a set. Once inflated to proper pressure, the aged/rotted tread soon delaminated. All belts intact, still held air.

Old tires = bad, and keep your spare properly inflated.

Correction,..replace "old" tires. They have a life expectancy of less than 30 years,.....to say the least. No matter the manner or method of storage.
Not that I completely disagree with what you said becauseyou did not say anythingwrong (persay), but old is old and old tires are dangerous tires. You can never tell when or how bad they will fail.
Even the tires that look perfectly good, as in my case, they still can not be trusted with your life or anyone else's. Just spend the $100 or less for a reliable spare. THEN , keep the spare up to regulation.

I just had mounted a continental tire spare. I feel better now, I will not be stranded away from my house.

Raydar, I have 88 brakes with 12" Vette discs....I was able to get a spare out of a Subaru that would clear these brakes- may be able to clear your 13s...


Not sure how old the tire is- but I'd like to replace it; Does anyone know where I could find a 115/70-16?

I certainly wouldn't be concerned about "my life" driving 5 miles on a spare at 35 mph, even if the spare is 40 years old. Especially in a low profile vehicle like the Fiero.

Everyone should have a $20 tire pump in the trunk that plugs into the cigarette lighter. I've had times where I came back to the car and I could tell I had rolled over a nail or something and the air was slowly leaking out and I'd top off the tire, drive it home to pull the nail and patch the tire or remove at home and take to a tire shop. You shouldn't need to install a spare in a situation like this (slow leak) and the time and dirtiness of doing that in a parking lot rather than having a $20 tire pump makes it a no brainer.

As Ogre said, it probably does stress the tire over time having it in the front compartment at 70 psi. I typically will check and fill mine if I'm going on a long trip, otherwise it's probably wise to keep it at 40 psi and then top it off to the spec when you install it using a tire pump in your trunk.

A co-worker bought a new 85 Pontiac Trans Am and he claimed the factory tire would not fit in the trunk even when flat. He could put the donut on but if there were 4 occupants total someone would have to walk. Maybe two come to think of it.
Should you have a flat where are you guys putting your oversized tires in the Fiero?

Even a regular Fiero wheel will only fit in the rear trunk.
Gotta keep it reasonably empty or move that stuff to the front after you get your spare out.
