Just got reply from dealer, I had asked if he would supply and fit tyres, on the off chance the local tyre fitter damages the alloy when fitting the winters.....So if I got my dealer to fit them and any damage done will be on his sholders
Here is his reply today :
Morning Doug,
Tyres prices are;
Dunlop SP Winter Sport 4D, 225/40/18 – Can only source 3D not 4D = £198.98 + vat each.
Goodyear Ultra grip 8 Performance, 225/40/18 – Unable to source from our suppliers.
Sorry but company policy is only to fit tyres supplied by ourselves.

Regards
David
Now I have done my home work regarding prices to supply
My tyres - delivered
Dunlop SP Winter Sport 4D - 225/40/18 = £140.70
Good Year Ultra Grip 8 Performance 225/40/18 = £139.90
Oponeo.co.uk - delivered
Dunlop SP Winter Sport 4D - 225/40/18 = £136
Good Year Ultra Grip 8 Performance 225/40/18 = £140
My local tyre fitter - supply + fitting
as above sizes Dunlops = £174
Good years = £183
My local fitter charges £15 for fitting if i supply myself but was very awkward with me supplying my own tyres!!!
So what do I do???
