We had a look at the date on the tyres and one is from before 2000 and has cracks in the sidewall, the other is 2009 so I went looking for some replacements. Nobody seems to carry the 135/80 13 size and ordering online would be easy enough but then there is getting them fitted. We found a local supplier who can get 145/80 13 next day so I removed the wheels and am getting them done later today. I'm keeping the same spare but it will only be for emergency use.

I replaced mine last year when the service highlighted the date issue. I use Blackcircle for all my tyres, very competitive and a have contracts with many fitting centres locally.
