What tires? What questions?

 

[Otter]

Just about had it with these tires. 2600 miles on them. 53 degrees went out got back 50 degrees Not going to be sidelined by these stupid tires. So questions, when the steering wheel is turned not locking but extreme what's that called when the tires KLUB KLUB and jerk the car around? Doesn't Bridgestone make tires for this car now also would those and the Michleins A/S replicate that annoying stuff. Any other replacement tires. Suggestions

Thanks,

In the general Discussion on C7s I asked a question about replacing the tires on my 15 Z51

So are you not liking the noise or the handling of the tires when they're cold?

Z51 tires replacements and noise

So are you not liking the noise or the handling of the tires when they're cold?

Just trying to understand the noise and the jerking the car goes thru when turned sharply in parking.
Will new Bridgetstone Run Flat replacements do this stuff? Any other makes of tires out there for C7S?

The noise and jerking you're experiencing on sharp, low speed turns is generally referred to as the "Ackermann Effect." That's actually a misnomer, as it's the absence of Ackermann steering geometry in the Corvette (and many other high performance sports cars). It's made worse by the high performance tires on the Corvette, especially the Z51, GS and Z06. It's perfectly normal, and won't hurt anything but your feelings.

So what is Ackermann steering, and why doesn't the Corvette have it?

When you make a turn, the inner tire actually makes a tighter turn than the outer tire. This is especially noticeable on very tight turns. So most cars have a steering linkage that actually turns the inside wheel more than the outside wheel when turning. That is Ackermann steering. The drawback to Ackermann steering is poorer steering response and handling at high speeds. The Corvette is a high performance car, and the steering linkage is designed appropriately for high performance.

I don't know about the specific Bridgestones you mention, but in general lower performance tires (think all season) will eliminate or drastically reduce the issues you notice. At the expense of cornering and braking performance. An alternative is to make wider turns (do a three point turn rather than a sharp turn, for example. Or just put up with it. It won't hurt anything.
