Flat Tire

[GW's Motorized]

If the tube was more than 2 years old this can happen...Right on the box they come in, they warn you that the Slime in the tube is only good for two years.

Ps...The Slime will no longer be a liquid but turn into a semi-solid when it gets old in the tube...If the bike wheels haven't been turning due to non use after it starts to solidify, it will congeal at the bottom of the tire resulting in your softball effect you are describing.

Not too concerned about that happening right now. By the time my tubes are 2 years old I'll be graduated and going to western welding academy. I sadly probably won't be able to take my bike with me.

My interpretation of whats written on the box is two years once air has entered the tube through the sealed schrader valve which would then activate the Slime to do it's job, but I also believe it important to not let a bike sit so long between uses so the Slime does not pool up in one spot in the tube either.

I'm not sure how long the tube sat on the shelf before I purchased it but it was only installed on my bike for a few weeks... max 6 weeks.. before this happened... Do they have any sort of expiration date (for lack of better term) on the box?

Tubes with slime are good for 2 years,
Bottles of slime have a 2 year expiration from date of purcahse
There is also a date of manufacture by the price code
