Just had new tyres fitted on my 2000 XM 3L at Chris Mullins tyres, Gloucester.
Worth the 68 mile round trip for a proper job done. Many tyre places are less than perfect (in my Lexus experience life) and quite a few can't handle wheels with no centre spaces.
Mullins guy had 20+ years experience-his landlord has several Citroens!
Definite recommendation.
