Do bicycle tires go bad in time?

they do but they can last that long

depends on light, heat, humidity, rubber composition, original condition

if they aren;t cracked they are ok

let the buyer worry about that

just say they look ok but you are not responsible

[basically the whole bike is the same story,

\ example..

what if a brake cable broke?

you can;t see it

you are not the expert

you could test ride it and it doesn;t break, can still break next day]

any bike buyer is responsible for his own safety

Yes, the rubber begins to decompose, dry out, crack, etc. The gummy sidewalls usually go first. Better to replace old tires, tubes, and rim bands.

No, they don't go bad. You still have to pump up the tires thou.
