30-40 year old NOS tires?

Post by sixbennetts » Mon Oct 07, 2019 1:59 pm

If there are no visible cracks inside or out, would you run them?

Highly personal and my thoughts are worth exactly what you paid for them. I've run some pretty old tires on cars and bikes that came on the vehicle with good luck. Don't think any were ever 40 years old though? If no checks/cracks or signs of tread or ply separation evident I'd likely run them on local transportation, but wouldn't mount them for hwy/freeway flying. If I mounted them I would keep an often and close eye on them. Human body repair is a lot more expense/grief than the cost of new tires. Depending on intended use and w/o actually seeing and fondling them myself I couldn't make the call.
Best of luck.

Depends on how they were stored. Years back The City had to trash a bunch of motorcycle tires that had been stored laid flat piled one atop of the last. Said short time ain't a big deal......but for months (or in our case, years)......store them upright. Said it had to do with compromising the sidewall to tread transition area. :foilhead:

Dig your thumbnail into the tread blocks, if the rubber springs back when you release and doesn't leave an indentation mark, OK. If the shape of your thumbnail is left behind in the rubber, it's fooked. Guy who ran the bike shop where I used to live told me that. Also it's UV that knackers tires so need to be stored away from sunlight.

Years ago I bought a used Michelin car tire, looked great but was about 8 years old. Mounted & inflated it, then watched a bubble in the sidewall grow to grapefruit size and explode before I could utter "what the f*** ?!" Been a little leery of old tires ever since.
Past afflictions include limey motocars and bikes, R60/2, R65ls, & a Citroen.
Now a DB Haanjo and Canyon CF SL Endurace, '87 K75s,
and a rusty 2012 GU bought new
dual K&N cones on homemade intake, 40/137.5
Raceway needles, Modtop exhaust, E starter delete
$29 VW Hydraulic steering dampener

I'm in the probably not arena. If you get the tires for free with free mounting and are only going to use them at lower speeds and where it wouldn't be a challenge if one goes maybe it would be ok. I think a better use might be getting them to someone that will use them on a period correct vehicle that needs age correct rubber for a restoration.

Best,

No unless it is going on static display at a museum somewhere.

Well, we'll see. I'm putting it away for the winter soon, so these won't be installed til spring, but I'll update the thread with results.

(For those who are curious, this is just one stupid move in loooong lifetime of stupid moves. 'I am a scorpion, it is my nature'. :lol:)

When I had my first Ural 2000 to 2007 you could buy brand new fresh Avons for that price not 30 to 40 year old NOS.
