Why Is it bad to ride with a slow puncture?

I did a quick google search, all I could find was people saying it's bad to ride with a slow puncture and not worth it but they give no reasons.

The back tyre of my honda cbf125 has a slow puncture (takes a couple of weeks to go flat when left on the drive). I think the offending 'puncture' is a crack or split about 7-8mm long on the part of the tyre that touches the road. It bubbles when I put soapy water on it. Anyone know of any reason why it is dangerous to ride with a slow puncture?

You have the wrong attitude about safety issues.

Why do police deploy stingers to puncture tyres?

Also under inflated tyres cause heat and destroy tyre walls.

do you really need to ask?

what's the pressure near the end of the period you allow it to deflate? Is it safe then?

what happens if the crack or split decides to expand when you're doing 70 on a bend?

Just buy a new tyre. Depending what it is you should get one for a ton or so max, even it's it's the latest greatest sportsbike £150 or so.

On the other hand would be a great epitaph on the headstone "He knew he had a slow puncture, but one day it...."




Or have I just been reeled in by Mr Troll???

Is this

a serious question??

You tyres are your only contact with the road (or, to put another way, 2 patches of rubber the size of your hand keeping you in a straight line), and you wonder why it's potentially dangerous if they aren't right?
