New Granny wheels - part 2

I love the new wheels on my old girl, they look great....but one slight problem 
Some may have thought they looked a little wide for the arches.......& if you did, then you were right 
It drives fine when on smooth roads, but over the weekend when I took her out on some dodgy country roads, I noticed that at 40mph & above, the tyres were rubbing the arches when going down sudden dips in the road.
I suppose a new set of shocks wouldn't go amiss in such an old car to prevent the normal 'bouncy old car syndrome', but I'm considering another course of action.
'Rolling' the arches isn't really an option, as I don't want to risk damaging the paintwork around them & thinner tyres isn't an option either...cos I love the wide beefy look of the 225/60/14s
Having the hub mounting faces of the wheels shaved by a few millimetres is the option I'm looking at. Is this possible ?....I've read about it on some American forums, but have never heard of it in this country.....anyone know of a wheel specialist, especially in the south Essex area that can do this ?

JC, I think this may weaken the hubs and could potentially be dangerous - this is the sort of mod which insurance companies can get picky about.
I would change the tyres to 205/65 x 14 - this will give you 10mm extra clearance each side of the tyre which may be enough.
Check this site : http://www.carbibles.com/tyre_bible_pg2.html for all you ever wanted to know, and more, about tyres.
Rolling radius is only 11mm different.

Ah, yes !
Thanks for pointing that out GOZZ, I didn't read it properly, still waking up.
I still don't think it's a good idea though as it would weaken the wheels.

Depends how much meat there is. If there is sufficient and done properly there should be no problem at all. Agreed if there is to little then not a good option.

 ...sissy girls tyres  ...... 
I've always liked the big beefy look of the 225/60/14s ....since I've had the car, that size tyre has been on it . The old (original) wheels still have 225/60/14 Avon turbspeed tyres fitted
Besides, have you ever tried looking for a 205/65/14 tyre ?........225/60/14 are like rocking horse doo-da, 205/65/14 are even rarer. If I went down to a 205, then it would most likely be a 205/70/14. They are a little taller (17mm bigger in diameter), but easy to get hold of & pretty cheap

JC,
Didn't know 205/65/14 were so rare - I just used the tyre size calculator to get the nearest rolling radius to your existing tyres.
Sorry mate, I was just trying to help.
205/70/14 would give you marginally better fuel economy

No problem Mike, thanks for the suggestion
Many tyres that old cars use seem to be pretty rare nowadays. Although I've never seen 205/65/14s, the 225/60/14s are still availalble from companies like BF Goodrich & Cooper. I did enquire at my nearest BF Goodrich supplier a while ago & they reckon I'd have to import them as they are only usually used on classic yanks like the Mustangs etc
