run-flat tires

[KP99]

I still have not decided to go with either non-runflats or runflats.
What happens to the sidewalls of the runflats after you have driven them 50 miles? Are they shot or should you take a chance
on them failing in the future?
Has anyone heard any stories on the new Goodyear GS-D3 non-
runflats?
Anyone have any suggestions?

The runflats that are stock on the C5 are good for up to 200 miles without air (flat). The other runflats are good for about 50 miles without air. The trade offs are less noise, better ride, better handling. The popular ones are Michelin, Yoko, Firestone; there are others. Check out www.tireerack.com for costs and specs.

KP,

I had the GS-D3's installed about a week and a half ago. I'm waiting to write up a review on these until I've logged a few miles on them. It's not my daily driver and I've only put about 150 miles on them and all of that on dry roads.

What I can tell you so far is that they are quieter than the GSC's and ride much better. The adhesion on dry pavement is also an improvement. I can't break these loose from a straight standing start but could with the GSC's.

If there is any noticable trade off, they aren't quite as crisp on initial turn in as the originals. They're not sluggish in my opinion, just not quite as quick. Net Net I'm pretty happy with them so far. They have an aggressive look too. Check out my avatar.
