Do you work for Ford by any chance? I'm sure if you'd had the same problems we've had you would have expected Ford cust service to help out a little, of course we don't expect them to replace all our wheels or even admit they have a problem but driving a car like a Nun because your wheels can't stand upto normal road use just isn't on.
Remember these are standard fit wheels on the Titanium which isn't even supposed to be a sporty model, I could sort of understand it if we had decided to upgrade and fit 17" alloys to it due to the tyre depth being smaller but we didn't. Surely Ford should accept some responsibility for the spec of the standard wheels/tyres as they are obviously not able to cope with normal road use and conditions.
No one manages to avoid all the dodgy road surfaces and potholes especially in the dark on unlit roads so the quality/specification of the wheels should be at a sufficient level to cope.
3 wheels ruined in one year in a car driven by a very careful driver (the wife) is more than bad luck, she drove a Puma for 5 years prior to this on the same roads with no problem at all and a Fiesta for 4 years before that (both with alloys). Seems like more than a coincidence to me.
I have a Titanium, same wheels, don't drive like a nun and had no probs whatsoever.
