Weather better time for some cycling

[Mr I]

Pulled my bike out of the shed last night and pumped the tyres, set off this morning, got about two miles in and the back tyre went out on me so I had to walk back lol. Oh well try again next week

[Bouncer]

You had to pump up the tire before you left, first clue something is a bit off. Lol

[Mr I]

Bike had been redundant for months so both tyres flat, all tyres leak air over time, fucking gorilla ass was hanging out the back also, got a chill back there lol! Fuck knows what the motorists thought

Do bike tires go flat over a couple months?

Do bike tires go flat over a couple months?

Yes they do. During the summer here I have to inflate every couple of weeks.

Why is that? Different kind of rubber or something?

Think it has to with a thinner more porous rubber and the pressure to volume ratio.
