New alloy wheel advise...

[jdf30]

Hi,
I have a '58 Ford Fiesta Titanium and unfortunately 3 of my 4 alloys are buckled. Having looked online, the Fiesta Titaniums alloys are prone to buckling, whether thats my fault or Fords is another matter. But either way, I am in need of new alloys.
So to help prevent this happening again in the future, I though about changing my current 16" alloys to 15" so I have a bit more rubber to protect the alloys.

I found a cheap set: http://www.wheelbasealloys.com/15_Inch_Calibre_Rap...
Without tyres: £279
Including budget tyres fitted: £439

This website says that the tyres will be: 195/50/15

So I went on http://www.blackcircles.com/ to get a price for tyres to see if its cheaper buying alloys and tyres from separate places. When I typed in my number plate, it doesn't come up with an option for 15" alloys. Is 195/50/15 the correct tyre size for 15" alloys for my car to keep the rolling radius the same?
My current 16" tyres are 195/45R16 84V XL if that means anything to you!

I don't have great knowledge on alloy wheel so please excuse my ignorance.

they look terrible, is there not another ford alloy you can get that isnt prone to buckling?

Get yourself on eBay and find some new/slightly used genuine ford alloys, you'll regret buying those.

I know, they're not the best looking wheels but I need new ones that aren't that expensive as I get awful shaking/vibrating through my steering from 35mph + when driving on the motorway for a couple of hours I end up quite exhausted from the vibrations through my arms. Anything is better than what i've currently got and I'm quite despirate.

I picked up some Zetec S alloys for my old 58' fiesta for £330 second hand on fleabay. Don't get those, they will look terrible, stick to ford alloys.
