old tire question

[JackstandJohnny]

looking at a set of 35s BFGs, they look to be in pretty good condition. but they are 10 years old.  quesiton is; are they ok? they are not cracked or anything like that, just want some opinions from people that know more than me.

Hand over the Iroks and I'll talk. 

Seriously, though....I believe they try to not install tires that are unused and 6 years of age, and the usual consideration is that any tires 10 years old should be replaced.

But perhaps someone in the tire industry is on here and can verify this?

rule is anything over 6 years should be replaced ..

a bran new tire can blow up on its first day out on the road just like a 10 year old tire can still be in good shape .
one of those things that there realy isnt a answer for

if the rubber still apears to be in good shape and shows no cracks then it might be worth a look

my spare is used and is 2 years old and its crack for S*#T  but its a spare

I deal with some tires.
It depends where they were stored. flourescent lights are said to deteriorate them, and 10 years of baking in a shed and freezong could take there toll on them, but then they might be fine. The question that you want to ask yourself is if they're cheap enough that you'll take the risk of having on separate and possibly blow, maybe on your steering axle at 110 on the highway, If they're strictly for off road I'd take a chance on them, but make sure you travel in a pack.

to my knowledge they were stored on a vehicle for so many years. sat in a garage.  they looked really good, i couldn't tell they were old. owner told me they were, only reason  i know.  he's pulling them off the rims today and having the tire shop inspect them, however, if there is no rubber coming off the inside of the tires, and no cracks/weathering on the outside, think they'd be ok?
i mean, i don't wanna have to worry about a tire coming apart on the highway either but they looked to be in fairly good condition.
