Widest Tire On Rear Stock Rims

Widest Tire On Rear Stock Rims
Hello everyone,
Please forgive me if this question was asked previously, as I am still fairly new to this site.
I have a 2014 Mustang GT/CS with 245/40/19 tires and was wondering what would be the widest I could go on the rear without causing any negative performance issues. I would like to take it up to 265 but not quite sure. I think its a 19x8.5 rim.
Thanks very much,
Rick

The tire manufacturers usually have the suggested rim width on their websites for all of their tire sizes. That being said they usually seem to leave some room as well. In my opinion, a 265 would be fine, but there are others on here that are much more knowledgeable on the subject that can hopefully help out.

Your stock tires (assuming that's what you still have), are 245/45R19, not 245/40. The Brembo package cars had 255/40R19 on 9" wheels. You can put 275/40R19 on your stock wheels, they will fit and work OK, but that rim width is 1/2" narrower than recommended by most tire manufacturers. 275/40 will match the overall diameter of the 245/45 OEM tires. Unless you are taking the car on a road course and tracking it hard, the 275 won't be an issue for you.

No plans to track the car just yet, however, you never know. Lol.

If you have stock CS rims then they are 19x9.5. 265 wont be a issue
