Scotty just to follow up on the phone call, I went out and double checked and the options are:
4x 235/75R15
4x 205/80R16
5x 255/70R15
If the tyre shops won't play ball, you can collect any of those sets at any time of the day tomorrow, but I'll need some warning before 8am for the 205s or the 255s, and before 9.40am for access to the 235s.
