My process is generally this:This will leave you with tyres with the minimum possible profile and largest possible rims for your specific car body.
- Increase tyre diameter as much as possible.
- Decrease rim diameter some. (Depends - some cars you can stop at 15 inches, other cars have to go down to 12 or 11.)
- Increase tyre width.
- Discover that I didn't flare the wheel arches enough.
- Go back to the trim tab (with the two cars in the symbol) in the "Model" section and increase the flare on the wheel arches.
- Go forward again to the tyre section.
- Increase tyre width to maximum (265 in this case).
- Increase rim diameter to until tyre width drops (because the profile got too small again).
- When it does, decrease rim diameter by one inch and increase tyre width back to maximum.
- Decrease wheel diameter until tyre width drops (same reason).
- Increase tyre width by 10 mm (I don't know why, but if you increase it by only 5, it doesn't work) and increase tyre width back to maximum.
Thanks, but that isn't my problem. All the bodies for 1976 only let me use 175 mm tires when I max out the width. It leaves my cornering stat at .71 g (93.2 mph) for 250 m, which is frankly rubbish. Is it my game or is it me?
