Just been online to put the code in for 5% discount with tyre shopper they refused to honour the code.... be warned......... needless to say I won't be buying my tyres from them. Confirmed by online chat.

I always use mytyres.com find them extremely competitive and you choose the fitting centre and date/time of appointment for the free fitting of your choice. They use National tyres and they do not charge any extra for tyre disposal and balancing or valves.

I use mytyres too -- especially for winter tyres - probably because they operate out of Germany where winter tyres are compulsory.

The other option is oponeo -- they have good prices too.

This is interesting, guys 

I have bought off Mytyres many times before as very competitive, however, I'm not far off needing a new set of Pirelli 225 45 17's assimetrico's, £86 per corner from mytyres and compared with Kwikfit listed at £75 per corner fitted ! Could be something to do with the exchange rate at present, so will be looking around when the time comes.
