Chevrolet Corvette Tires and Wheels
I just traded my 1991 Vette for a 2002 Vette and the thing I have noticed is a lot of road noise with this car. I was just wondering if the run flat tires are the reason for the sound. All of the C5 cars that I drove had the same sound. Is there a tire to replace the ones on my car with that are not so loud?

Of course, I don't remember my C4 as being all that quiet either!
Only other thing I can think of because of the "pulsating" issue is an ABS problem. Have never heard of anyone having a problem with the ABS module but???
I take it you feel nothing thru the steering wheel?
Guess if I were you, I'd do a couple hard stops wherein you activate the ABS. Cannot offer you any technical reasons why I would do this except frustration and the possibility that the ABS sensor would "re-set" itself.
Did this "pulsating" per chance begin after you had to make a hard stop and the ABS was activated?
Can't remember from your original post but did you replace the pads along with the rotors?
Also, I believe you indicated the rotors were new. Were they possibly turned and reinstalled? Manufacturors have specs for minimal thickness of rotors and they can usually survive being turned once.
Post answers to above and I'll check with some Vette gurus and get their input.
maybe you need new calipers? check out Ebay pick up the zo6 caliperss they work great, but i think there the same, just red.
good luck,

Flats and the other set, Z06 size has Kumho MX tires for the
track. I say that the Kumho's are supposed to come off when
I'm not going to be on track for a few weeks but it goes
much longer than that at times. I've had a few nails and
been very lucky that it became a slow leak and I check
pressures a lot so I caught it each time without getting
stopped on the road. Either approach works but some day I
may be waiting for AAA to get me to a tire shop. If I did
not run track and used the car for touring I would keep the
run flats all the time.

foot. I have Michelin run-flats on my C5, when I take off
the track tires and I get the same mileage as my OEM GYs. As
a matter of fact, my Michelins are quieter than the OEM GYs
on the wifes C5, look better and I like the grip better. Running
my Z06 size wheels with 275/295s really spoils me
for going back to stock C5 size tires. That is unless you
want to drift some and enjoy the oversteer .

Mine is a 2004 and I believe the sizes are P265/40ZR17 front and P295/35ZR18 rear (both non-run flats).....
they don't have a 265/17. I price them at Tire Rack and
then go to America's Tire/Discount Tire store locally and
they match the price. Since it used to be about $10 per
tire to ship from Tire Rack, they add that to the price and
then charge for installation. Very good deal.
Those are on 9.5 front and 10.5 rear wheels. I'm also aware
of guys that run 295 tires on stock 9.5/18 wheels.
Randy
Sounds like you have the stock-size Z06 C5 wheels. Do you notice any problems running the 275's on the front around town (I know you like these on the track...)?
Any drawbacks you would like to comment?
driving. Matter of fact my run-flat Michelin's have been
in the garage for over 6 months, sitting. After running a
wider tire you get spoiled with the grip, I've even had the
Active Handling come on in the wife's C5 coupe on stock
tires a couple times, expecting more grip than the stock
size tire provides. Running the Z06 wheels on a coupe is
also very nice.
Randy
in the front with the 275's, I think it is ACI model. If I
didn't have that, there is no rubbing. I know people at the
track that run up to 305s in the front without rubbing issues.
No issues with turning radius either.
Randy
does it more than the smaller. Pays to keep good grip on
the steering wheel, which from time on the track I some
times have a pretty loose grip, more relaxed driving than I
used to be. Another thing to remember where there is wet
conditions, I have hydroplaned at 65 on the stock 245s in
the coupe, very deep conditions in a big down pour, but with
the 275s I'm pretty slow when any rain is falling. Not bad
if the road is just wet after a rain.
Also, presumably I get less MPG with wider face of the
tire to the line of travel for wind resistance. Then again
on the way back from Reno-Fernley Raceway last Sunday I
reset the mileage computer as I left the track and when I
got home it was at 31.7mpg. That was after stopping to fill
up in Reno and then putting in 6.5gals to top off at home.
That puts it at about 31mpg. Well, not bad after it was
reading 7.4mpg on track .

My mileage back from Vegas to (So Cal) was 27.7 (could it be the LS6 engine explaining it?). That was also by putting it in neutral on some of the steeper down-grades, pushing 80 mph and having to do some braking to avoid over-running some folks. Leaving it in gear and using engine-braking seemed to see the mileage drop from 99.9 to the 40's and 50's on those freeway stretches.
I guess RPM kills mileage, even if it's 1900 RPM vs 750, w/ a closed throttle.....
how long mine last since I track the car at road courses and
burn up track tires in about 750 track miles. However, on
the wife's '04 coupe, she is still on the OEM GY's at 23k,
but I'm just about to change them for the Michelin's before
we get into wet part of winter.

Based on anecdotal evidence
[ posts elsewhere ]
seeking equivalent performance but
quieter & better ride,
I would have replaced the tires on my 2007
with Michelin Pilot Sport Run-Flats...
If you do not want RF tires,
most any other tire will be both
smoother riding & quieter than OEM.
Just my 0.02 gallons worth....
Enjoy!
