RE: Grip

[Skapper]

I'm still getting used to the AWD, so this may seem like a bit of a noob question. I'm asking to be on the safe side.

Low to moderate speed tight corners in my AWD seems to provoke tyre noise. Two corners come to mind where this happens consistently; one is a 90 degree turn and the other is essentially a 180 degree turn. Neither of them high speed, usually 1st and 2nd gear, but at mild to wild throttle opening the noise produced hints at the limits of lateral grip being reached.

Car still holds direction and there is no abnormal feedback through the steering wheel. It "feels" okay and holds its line.

Wheel alignment done last week has quietened it but not a lot. The tyres are new 235/45 17" Khumo's. Good shocks & springs and everything under the car looks in good condition.

As I've said the car feels okay,holds direction and doesnt hint at losing traction. Just this noise.

Am I being a being a paranoid android here, or it this either an AWD thing or time for a different compound of tyre?

the tyre screeching doesnt always mean its at the end of its grip, if it only happens around a few certain corners the road surface may have something to do with it and may make the noise seem worse, id say the only way to get away from it is to use a grippier tyre.

Nice to know I guess. The surface of these corners seems quite good actually.

What breed/model tyres are you using? Is there a poll or thread for recommended tyres here?

What Kumhos are you running?

[Lugo]

Checked your tyre pressures lately? What are you running them at, and what sort of corners are we talking about in a great sense than their degree of turn. Off camber turns will provoke screeching a lot sooner than those on camber or flat.

The noise is the road begging for mercy under your four traction wheels

Honest simple solution, spend more on your tires. :-)

Tyre noise on corners is a good indicator you are heading towards the limit of your grip, however, different tyres (and road surfaces/conditions) can lead to this being either progressive, but sometimes a snap loss of traction which is obviously bad. So be careful :-)

I haven't noticed any additional noise when cornering compared to the FWD, although the slight understeer is noticeable. One thing that I noticed early in the AWD experience is that it promotes over confidence, especially in the wet, which may be a bit of a trap for us in some situations.

While we're on this topic, what do the members here recommend for tyre pressures?
