Tracking needs doing!

Hello people

Wondering if anyone can help me? I need to adjust the tracking of my locost 7 as I am getting wear on the inside of the tyre.
I am not shore what it is set too at the moment. Has anyone got any idea what will be the best setting?

Cheers

Rob

I set mine up using a laser level marked an equal measure at the front and rear of the tyre held the level flat on the rim and aimed it at the line front and rear, then measure distance between the fron marks and the rear marks and adjust to suit.

Took it to be tracked and it was spot on

Agree it's probably tracking but excessive negative camber can do this too.

Camber first then toe-in --- also check the tyre pressures aren't on the high side.

Surely excessive side wear normally indicates that pressure is too soft doesn't it? High pressure wears the centre too quickly.

I would set the tracking with a fraction of toe in (0.5mm ish) This allows for any slack to be taken up and tends to make the steering less twitchy.

If the pressure is to high the tyre wall won't conform to the road so if the camber is wrong it will only run on one edge of the tyre.

Steel belted radials don't change shape as much with as pressure as old fashioned textile radials or xplys.

Most modern low profile steel belted radials the crown of the tyre is designed depressed when deflated and because the steel belt doesn't stretch much remains that way when under pressure. Or to put it another way the shape and outer diameter of the tyre tread dosen't change much with with changes in pressure.
