what would be a good tire size to put onto 17 inch rims using BF Goodrich g-Force T/A kdw tires? and how wide of rims??

How long is a piece of string?

What tyre diameter do you want?

Do you want to keep the existing speedometer gear drive or do you plan to change it to suit?

How much backspacing do you get on the wheels you are thinking of?

What is the ride height of your rear suspension like? High? Low?

Do you want the same diameter and width all round?

Do you want to make suspension changes to fit wider wheels?

How about cutting or rolling the wheel arch lips?

Have you read the other threads in this section about wheel and tire sizes?

At the end of the day the ONLY way you can be sure the wheel and tire combo you pick will fit YOUR CAR is to get under your car yourself with a tape measure and measure for yourself.

Have a look at the wheel you have on there now and measure how far you can go bigger in all directions. Remember the bigger the aspect ratio the taller the tire on the same wheel.

Use my spreadsheet to work out what the diameter of any wheel tire combo will end up as. http://www.challenger440.pwp.blueyonder.co.uk/maths.xls

Oh and when picking a tire pick one just a little wider than the wheel width. But not too much wider. About 1.5 to 2 inches wider.
