Anyone know who makes good run flats and are they any good?
Don't want to ruin my rims if I do get a flat and take out the spare tire for weight and space.

I know this won't help too much, but the later C4 corvettes came w/ Goodyear runflats I believe. You might want to PM RogerTTR and ask him what ones are good and what's available for your application.

run flats only work for 50 milea and sometimes u dont even know u have a flat just stick to reglar tires and put a tire repair kit in trunk
