Look like a couple of very good websites there, thanks.
195/45R16 V 80 are fitted on mine now (rear, anyway), but I checked the Vehicle Registration Number Search & that's thrown up completely different ones, even the upgrade option ones. They're (original Ford spec) 195/50R15 V 84, (upgrade options) 195/50R15 V 82 or 205/40R17 W 84. The handbook doesn't mention any R17 or speed rating or load index. Have I had the wrong ones fitted all this time ?
Sorry to "highjack" ... back to op, I'd get the wheel alignment done elsewhere. The service centre will (probably) load any routine work anyway, 'specially a dealership.
The last place I bought tyres from (an independant) didn't do alignments but told me it needed to be done as the tyres'd worn unevenly. I went to ATS (I think), who found the tyres had been put on inside out and they were gonna charge for switching them round ! Needless to say, I went back to original garage, gave mechanic a right flea in his ear (he's a friend of me other 'alf), but he'd got his apprentice to do them. Haven't been back since ...
