The original equipment Goodyears on the Z06 are about gone. Having suffered a non repairable flat in the middle of no where, and 4 days of down time, I want to investigate run flats for the Z. Does any company make ones in stock sizes, and does anyone have any feedback? The car is a daily driver and I am not concerned about ultimate performance, but reasonable tread life and good performance in the rain.
However, firestone makes a special SZ50 firehawk run-flat that is superior to the Goodyear OEM Eagle F1 EMT for the base model corvette. Its only made in the C5 GS sizes.
If you really want runflats, those are your best choice. You might have to get GS wheels though? I dont know if the Z06 rims are correct for those tires.
