Tyre pressure checked, always do it to 33
3 tyres between 32 / 33
front driver tyre at 26.
It looked a bit 'not rounder' as the rest, and it has a flat nail in it which I think has been there a while!
so it looks like a slow puncture.
Should I keep topping up pressure every so often or do i need to get the tyre changed?
Blardy hell, I can do without the expense!
