From what i can gather there is more of a difference in the Chally's and Cuda's, when it come to fitting bigger rubber

Yeah Steve, I was really just commenting on the fact that there can be a side-to-side difference. the tyres I had that rubbed were actually 255! But they were not the right b/s, so my point was that whatever you are fitting, just because one side fits doesn't mean the other def will.

David, on the overall width, whenever this Q is asked, as it frequently is both here and in the US, the concensus is pretty much that on an E-body, with between 4.5" and 4.75" of b/s, 275/60/15 (or equiv) should fit nearly everytime, and 295's can fit in some cases, without any modifications.

There are plenty of articles on the web about measuring your car to get the right b/s and tyre width, personally if you want to get the widest possible rubber without mods, I would measure your own car on both sides and then you will know for sure instead of hoping for the best. that is what I'll be doing.....

best wait and try some one elses on your car first or buy one of these maybe;

Wheel and Tire Fitment Tool, Diameter/Width/Backspace/Bolt Pattern, Each

Percy's takes the guesswork out of proper wheel fitment!
These revolutionary new tools allow you to get a perfect fit the first time and every time when selecting new wheels and tires. Percy's WheelRites eliminate returns and delays due to an improperly specified wheel. These tools bolt onto your vehicle's hub to precisely simulate bolt pattern, wheel diameter, wheel width, backspacing, and tire profile. The WheelRites allow you to simulate a number of different sized wheels and tires without the expense or hassle of having multiple sizes of wheels and tires on hand.

Superb!

(Bit pricey though unless you're going to be using it a lot).

Yeah, nice tool, good example of where buying one "for the club" would only cost us a few quid each but could be made available whenever required.

But otherwise shouldn't be too difficult using a bare wheel or wheel/tyre (i.e. standard steel) and measuring the difference you need from that. My plan is to use that for tyre clearance, and a plumb line, and some chalk on the garage floor to get the right b/s. (remember on E-bodies the leafs taper so you need to make sure you measure the distance to the leaf at the narrowest point).

That is all i did. Measured the existing wheel spec and used a tape measure to see how far I could go in all directions.
There is a lot to be said for just getting off your bum and getting under there with a tape measure.
