Need New Tires for C5 Z06


ebalentine

Recommended Posts

I have a 2003 C5 Z06 that needs new tires. I'm having a hard time find a complete match set of 4 tires. I'm looking for standard RUN FLATS and NON-RUN FLATS. Because the fronts and rears have different size rims (Stock) it leaves very few choices.

I don't want the Goodyears and have to buy new tires in 6 months. I don't race, son't drive in dirt or snow. I want a longer wear life out of the tires. Fronts are 275/40/17 and rears are 315/30/18. Any suggestions?

Hankook Ventus V12 Evo..........mine are wearing great and they're quiet. Not sure about Z sizes but they were a great price on my base model C5

I have the Michelin PS2 run flats. This is my 3rd set, preparing to buy a 4th set. I love them. Good ride, good handling and grip, and the one set I DIDN'T thrash at the track I got 30k miles out of.

I like teh Michy Pilot ZP's also (they live forever it seems), but I don't think they cover your sizes...

For matching front and rear I think you're limited to teh Michelin Pilot Sport in those sizes. I've used them before with decent results, other than they are expensive (like everything Michelin it seems).

I got Michelin Pilot Super Sports non-run flats, whisper quiet, excellent grip. A ton better than the Firestone Firehawk tires my vette came with.

I agree with the discount suggestion .... These guys do a great job.

You mite also consider BFG G-Force Super Sports ... ran them on both C5s ... great mileage, quiet and love the handling ....... AND ... less money then those everybody runs because everybody runs em ........... try it ... you'll like it #justsayin

I disagree with Mr. Russ. I had FS's on my last.C6 and got 35k+ out of them. You'll be lucky to see 25k from the PS2's and the cost twice as much. The key is the FS's "came on his Vette". I'll bet they were about shot when he got em.

Eddie44, might be just the one's I had but they were fairly new. What I did not like about them is that they were squirrely on less than perfect roads, loud and cornering grip was not good. Night and day difference with the Michelin Pilot SS.

I'll admit the PS2's were very slightly quieter but not enough to make up for the huge increase in price. The squirreliness may have been the ones you had. For some reason Vette tires seem to get that way the more they wear.

I recently took a tire forensics and failure analysis class (seriously). I learned that tire wear, heat cycling, and exposure to ozone will make the rubber harder as they get older. Harder tires grip less than softer tires (duh).

Maximum grip occurs when the rubber starts to tear off the off the surface of the tread when the tire just begins to slide/spin. Harder tires will slide and tear sooner than soft tires.

If things were harder as they got older then there would be no need for Viagra :leaving

You got that right young man! Enjoy it while you got it :laughing gut bustin::laughing gut bustin::laughing gut bustin:

Will you still need me...

Will you still feed me...

When I'm 64????

Two more days :at wits end:

I am running a set of Bridgestone Potenza RE050A Pole Position Run Flats on my 08 Z06, overall very happy with these tires, not cheap at $ 1650.00 a set though.

What you wrote makes no sense.

1. harder tires grip less than softer tires

2. maximum grip is when the tire begins to slide

3. harder tires slide sooner

According to that, harder tires grip sooner than soft tires, yet grip less.

My pencil eraser doesn't work that way when it gets hard. It tears off quickly when soft and not at all when hard.

When the tires are rolling and not sliding, that is called static friction. When the tire is fully sliding, that is called dynamic friction. Static friction is greater than dynamic friction.

However, in brake tests involving accelerometers, maximum deceleration occurs when the tire is just starting to slide, on the transition between full static and full dynamic action. This is where ABS tries to function. The tires will alternate between short slides and rolling as the computer modulates the brake pressure.

A skilled driver who can apply the exact amount of brake pressure to keep a tires on the very edge between static and dynamic friction will beat an ABS stop.

The reason is that maximum tire grip occurs just at the edge of sliding when the rubber is just starting to shear. A softer rubber compound has more elasticity and will shear at higher braking forces compared to harder tires.

I don't recommend trying to stop using pencil erasers, under any circumstances.

Harder tires will reach their maximum grip sooner, at lower braking forces than harder tires.

Your pencil eraser has more drag (friction on the paper) when soft and it slides with less friction when hard. But this is in pure dynamic friction mode.

So you're saying the maximum grip of hard tires could be next to nothing, but they get next to nothing real quick. That makes sense, since sliding on hard tires happens immediately and doesn't seem to get any better before the crash.

We look at the same physics from different perspectives. You with front tire deceleration and me with rear tire acceleration and pencil burnouts.

Toyo's have some good tires. I've been running Proxies TR1's for the last 25k, I autocross with them as well. Road noise is good, tread wear is 240, temp is A, these are HP Summer, and perform well in the rain with good channeling (although that's not much of a problem here).

Ah - the old coefficient of friction for a skidding tire, huh?
