I've always found the price difference between delivered only and fully fitted to be about the same as my local good independent charges for fitting, valve and balance however the tyres are supplied - as long as you can choose a known local fitter when ordering online it's 50:50 - if you can't choose, then have them delivered and arrange your own fitting.

I use Event tyres, mobile tyre fitting company. They fit the tyres on your drive or at your work. Very convenient. no waiting around for hours at the tyre fitters. I can be getting on with work at home while they carry out the work on my drive. Very timely, curteous and they do a good job. I am having a new pair of Continental Sport Contact 3 fitted on Wednesday, whilst I am stripping off the wall paper in my hallway. They are also £8 per tyre cheaper than my local tyre fitters. I have used them three times so far, and heartily reccommend them.

There are several tyre firms in Derby that beat online firms and Costco easily. Why not ring a few local firms for a quote?

mytyres.co.uk used to be cheap and to buy and fit myself saved £25.00 per tyre but prices have crept up and there's not much saving anymore.

Shop around is all you can do & id rather fit my own while i still can this machine is old but still works.:-)
