Hi Chaps,

My 15 year old Mk 2 car porter tyre is finally giving up on me....
Got a slow puncture and needs inflating every 10 days or so.

I imagine the inner tube needs replacing, does anyone have a link to the correct size and somewhere cheap?

Also, any tips to removing th tyre to replace would be greatly appreciated.

cheers
MH.

Is it defo a puncture? Reason for asking is the valve pin seat can sometimes come loose, especially with age, you can tighten them up again. Test with some soapy water covering the valve, see if it bubbles. There is a tool for doing it, looks like a mini 2 prong fork but you can do it with a fine head screwdriver like a electrical 1.

Tyre / tube size is normally on the sidewall of the tyre.
Check the valve as suggested.
To fit a new tube make sure it's fully deflated.
Presumably it's not a split rim ( bolted together) and assuming a normal shaped rim then as follows.
Break both the tyre beads from the rim, push the tyre bead into the well of the rim opposite the valve then lever one edge( bead) of the tyre over the rim starting at the valve.
Pull the tube out, check for debris, nail, thorn etc inside the tyre, fit the new tube making sure the valve is secure and doesn't slip back into the tyre.
Refit the tyre starting opposite the valve and finishing at the valve. If you haven't got any tyre soap then use washing up liquid or some form of liquid soap to lubricate the tyre going over the rim. Make sure you don't pinch the tube.
Depends what kit you have but might be easier for you to take to your local tyre fitter.

I had the same happen to me, I just repaired it with a bicycle repair patch,

to get the tyre off I deflated the tyre completely, stood on it and used a cro bar like a tyre leaver to remove the tyre,

Find the puncture , patch it, and replace the tyre as you got it off,

Must be five years ago I did mine !

All I did was get a new wheel from homebase, a wheelbarrow wheel pumped up and ready to go
Are you sure?

This action cannot be undone.

Yes, continue
