Hey guys, I'm new to the forum. I've got a '15 SHO with about 29k miles on it. I took it to a tire shop to have a slow leak checked out (tire had a screw in it), only to be informed it couldn't be patched/plugged due to it having cracks in the sidewall. Upon further inspection I had two other tires with the same problem. These were the Goodyear Eagle F1 Supercar tires that came as standard on the Performance Pack option. Has anyone else had similar issues? The tire tread on the other is getting low anyway (6/32nds currently) so I need to replace them in the near future, however I don't want to put the same type of tires back on the car if they're notorious for this type of issue.
