Q If you are buggin in do you NEED.........

[bigpaul]

honestly, most of them can get 30k miles to a set

yeah, that's on main roads and motorways, not on the sort of roads I drive on. I change mine every year end of feb/beginning of march even if there is tread left on it, regular as clockwork, I don't let them get worn right down, had a couple of punctures doing that in the past so I don't take the chance, not sure what the mileage is I just do it on such and such a date.
