Tyres Scrubbing

[flashpixx]

Kumho Ecsta KU31 205 45 16. Just had H&R 35mm coils and Bilstein B8 dampers installed. Front left tyre from negotiating a roundabout at too high a speed?? Front right has no scrubbing.

Is this a common complaint with these Kumhos?

Yeah the ku31 goes a bit like that with hard cornering. If you dial in a touch more negative camber you can offset this wear.

Wheel alignment? Pressure? Looks normal for some "spirited" driving, maybe a little understeer, hence you're scuffing the shoulder off??

wheel alignment is good, 36 PSI (now up to 38 ) spirited driving yes, a little understeer yes probably...

They do tend to eat the outside edge quickly when driving hard.

It's just the tyre. The tread rolls over onto the shoulder somewhat. More so then a regular tyre.

2 degrees negative front.

1 degree negative on the rear.

Nothing to worry about, normal wear if you're driving it hard. I have the same set up, tyres and suspension. I've got chunks of tyre missing from the outer tread blocks and scalloped, it happens. Though my wear is from the track, not street. If I think of it tomorrow I can add a pic, that'll put your mind to rest

Because the circuits up here are all right handers, the left side cops a flogging. The rear left tyre started life on the front left so has sustained more damage from doing sprints. With the "happy laps" we do, whilst we spend longer on the track, it doesn't allow for consecutive hard laps so the tyres don't fall apart. I've done about 20,000kms on these and should get at least another 5k out of em. and have been doing happy laps monthly, so probably ~10 of them and perhaps 2-3 sprints.
