Post Libra tyre wear
Is it normal for GTM Libras to take the outside off all its tyres or does my suspension need setting up.
Thanks Matty

Doesn't sound right!

My Libra didn't wear unevenly across the tyre width but it might depend on how the car is being/has been driven.

Driving style and the correct setup for that driving style :wink:

Might be your running too much Toe in, certianly worth getting it checked to see where it is and see if its miles away from suggested settings

Got to be too much toe-in, my rear tyres wear evenly across the tread although the near side wears out quicker, the front could also be to much toe-in but driving style adds to wear as well.

Suggested settings :lol:

It is on all tyres, so have all the wheels got positive camber i.e leaning out. I would suggest if so that it is removed and go for approx straight up perhaps a smidgen negative and/or toe out so go for a straight ahead, again perhaps a smidgen toe in.

No specific info on the Libra, but the above seams to work well on most rwd sports cars :?:

Just got my tracking gauge's down from the loft to check what mine's set at.

1800vvc, NO anti-roll bars.

Rear
Starting with the measurement's from the gearbox to the centre of the first bolt of the bottom ball joint on the wishbones, near side 343, offside 625.
Camber -1.5*, 30min [3.6mm] overall toe-in.

Front 20min [2.4mm] overall toe-in.

Tyres, 205's all round, 20psi rear, 14psi front.
---------------------------------------------------------------------------------------

I'm thinking you've most probably got to much toe-in on the front and 0 camber on the rear :?:
