69 Dart swinger tire size

Based on everything I have read, this is correct that a 225 is the maximum width tire you can run on a 14" wheel at all four corners.

However, the stock wheel tubs can actually fit up to a 255 width tire with the correct backspacing.

The stock wheel tubs will hold hold at least a 10.50 or 275 width with 4.75-4.5" backspacing.
