Triumph Stag wheels

So my car has been painted and is getting closer to having plates on it. Now it is time for wheels and tires. The car has a set of five stock wheels (one spare) that are 14 by 5.5. I would like to either put some new little bit wider wheels under it, like 6 to 6.5. I would also like to move up to 15s so its easier to find tires for it. My question is, What is the bolt pattern? I know its four lug, but is it 4x100 or 4x113.5 or some odd ball pattern. I also need to know the offset that works. I want to get 205 tires on the car (up from the 195s on there now). I want to get a set of enkei 92s if money allows. Thanks for any help and a picture for reading!

4x4.5.

Which is also 4x114.3

hmmm that opens upalot of new possiblities....

In reply to VonSmallhausen:

You can get wheels off a lot of Japanese cars depending on what offset you need.

Let's see: the 4x4.5 or 4x114.3 bolt circle was used on: Nissan/Datsun 510 and 4 bolt Z car, MGB (MGB LE wheels are Stag pieces), TR6, 1970's 4 bolt GM (Nova etc), 4 bolt Mustangs before the Mustang II, a whole bunch of different Toyotas of the 70's and '80's like the Celica and Supra, 4 bolt Honda Accord (but watch the backspacing), I'm sure I'm forgetting a few others.

How is that a Stag escaped The Aussies great Stag resting grounds?
