Whats the biggest tire you ever put on a 14 x5.5 rim

I had 245-60-14s on stock rallyes but as said its not the best fit. The side wall buldge which isnt the best for handling.

I now have a 225-70-14s on mt 5.5" Rallyes and wouldnt go any bigger. I actuall plan to switch to a 15X7 with a 225-70-14 in the future.
