Tire size

I am trying to figure out what the widest tires I can put on my 2013 Boss 302 Laguna Seca. But on the factory LS wheels? The front is 19x9 and the rears are 19x10 I believe. Can anyone help me out? Thanks in advance.

There are a few threads on this topic for both street & track set ups at BMO (bossmustangsonline.com). Before getting too radical with extreme widths, you should talk to a reputable shop about how this will effect how your car handles and what other suspension mods would be required/recommended. Imagine wrecking your car because of unpredictable understeer while cornering... :nonono:
