Need Tire Advice (and sizing for my Chrome Z06 reproduction wheels)

007 · 03-08-2003, 02:41 AM

I upgraded my 2000 C5 to the Z06 chrome reproduction wheels (18" rear, 17" front). At that time, I had the original Goodyear run-flats installed onto the new wheels. What I'm not sure is if the Z06 reproduction wheels are the original C5 stock size or the Z06 size.

Basically, what is a nice larger tire to put on these Z06 reproduction wheels? Second, I would like to retain the run-flat capability to what brand is best and still run-flat.

This is a tough one. If they are ZO6 width, you can't run runflats. It has been done, but does not look right IMO. You would also be risking wheel damage because of the narrow tires. You can go with 265/40s and 295/35s if they are indeed ZO6 size. There are lots of rear tire options (295/35), but only Goodyear supercars, which are stock on the ZO6, in 265/40s (I think Pirelli may make a 265/40). You could go to a 255/40 and run BFGs, or to a 275/40 (just the right height) and run Michelins.

If you do have stock C5 size, you have lots of runflat options. Michelins and Firestones seem to get the best reviews. Michelin also makes the Pilot Sport, a great non-runflat. Good luck.

If you want to stay with runflats, the stock C5 sizes were the largest (in both rolling diameter and width) available from any tire manufacturer the last time I looked, so it's pretty much a no-brainer on the size.

If you want to abandon the runflats for the purpose of going wider, you really should measure the width your wheels first. If you don't know how to do it any reputable tire shop can do it for you. Sometimes it is stamped on the back on repros.

FWIW, I picked up a set of GM factory Z06 wheels when the Z06 first came out and long before they became popular. I ran my original runflats on them without issue, including appearance, and the Z06 rim sizes were an approved rim width by Goodyear for the stock non-Z06 runflats. As to appearance, I later went to the non run-flat stock size Z06 tires which IMHO look better, but they look better mostly because they have a wider footprint and not so much because of how they fit on the rim.

I called Goodyear customer service tech dept. after reading that the EMT tire can go on 9.0" to 11.0", on the Goodyear Tire web page.

Goodyear tech called me back next day to report EMT has no issues on the Z06 10.5" rim in their testing.

His big concern was that EMT tires must have a monitoring system, which we do.

Sounds like the question is do you want EMT, or big bad boys.
