What exactally does run flat mean.

I keep reading about posts and threads where owners are getting fllats. I thought that run flat meant that the tire would not go all the way flat?

thanks

It means that if the tire goes completely flat, 0 psi, you can still drive the car at speeds of 55 mph or less for 100 miles.

 

You need them since there is no spare tire in the car. Get ready to spend 380-420 each to replace.

 

 

The cost of enjoyment.

What kind of mileage have these been getting, hopefully more than the Z51s.

thanks

I am refering to the base C6 tires here.

 

I bought a gauge to check the treadwear on my C6. Looks like I'll probably get 28K to 32K on my non-Z51 05 C6. The right front tire I had to have replaced after hitting a road hazard was $303 without balancing & mounting.

 

Went down to zero pressure two weeks ago. The tire operated perfectly! I drove about 10 miles at speeds up to about 45mph, as I headed to a GY tire center. No damage to the wheel. It was weird to press firmly on the sidewall and have plenty of resistance, yet when I pressed on the tread area, it would cave in!

Driving on a flat is def. cool.

Thanks for the info.

I had two flats on my C5 and on one of them I finished going to dinner that night, went home, got up the next morning and after breakfast went to the tire shop and got it fixed. Definitely cool.

The only problem I had was when the DIC started dinging and said that I had low tire pressure, I quickly maneuverd in traffic to get to the side of the road...and then remembered that I had runflats and didn't have to do anything. So I just took off again and continued on my way.
