I too have the 7-spoke alloys on my year-old titanium. I remember hitting a deep pothole back in snowy December & the front nearside taking a hefty whack!
During its 1st service this week, I was told both front wheels are everso "slightly buckled". I haven't noticed any difference whatsoever in the feel/handling due to the "buckles" being so miniscule.
Was advised to change them (£322 for a pair) - but I'm not bothering as - like the Ford servicing dept told me - "it's barely worth doing so, the buckles are so small". That will do me!
But . . .
I have owned many cars in all my years of driving - many (if not most) with alloy wheels - especially the past 15-years or so when most manufacturers added them as standard. In that time - I have driven into a good number of potholes, hit large rocks/stones, the odd kerb, debris on the motorway, you name it! Yet this is the very first time ever that I have had a buckle of any sort - ever. I never had any problems with damaged alloys until now. I conclude therefore that - despite the fact I love my Fiesta titanium like I do - Ford's alloys do seem to be "weaker" than any i've come across in previous makes of vehicle! Maybe it's all part of the "making the new Fiesta lighter" in weight than previous models? Ask the good handful of people on here with the 17" alloys that have had problems if they agree?!?!
