Excessive Tyre Wear on Inside fronts?

[dictys]

Did my front brakes this weekend and noticed that my tyres are excessively worn on the inside edge.

I'm going to replace all my tyres with Dunlop 9000's but is this common or does my car just need aliment and tracking done?

Dictys - my v8 has always worn its fronts on the inner edges. I've had the geometry checked and its spot on. Its just a characteristic of the car. Travis has suggested that you *can* reduce the camber without having too much effect on the handling but giving you longer tyre life, but i prefer to keep the stock setup. I've just swapped my fronts left to right at about 6k miles (demounting the tyre, as my s-02's are directional) to try and even out the wear over the life of the tyre.

Yeah, Rob has done what I want to do on my S4 as the inner edge is worn more than the outer. I have Good Year F1s and they are directional too.
Its basically down to the wheels tilted in at the top to give better turn force, as you corner the tyre will flatten out putting more of the outer in harder contact with the road and thus giving better contact over the full area. I think if the tyre was completely flat in a straight line when you cornered hard the tyre would grip lots on the outer and hardly any on the inner, so they tilt them so you get the full contact during the most aggressive cornering. Check out touring cars, they are quite obviously tilted in at the top, or any other race or high performance car.

It may not be a camber issue. The steering geometry of the Esprit "features" anti-ackerman. When turning, the inside wheel is deflected less than the outside.

Do you guys back up with the wheel cranked all the way over? It tears up the inside of the tire on the outside (confusing description there...) because the outside tire is literally dragged along.

I have to turn sharply while backing out of my garage and the inside of the passenger side front tire always shows more wear than the driver's side. Eventually, it produces a slight pull in the steering. I try to turn as shallowly as possible to reduce the effect, but it still happens.

Same here,Have always put it down to powering into our UK roundabouts. Never notice wear quick enough to rotate fronts,so end up getting the tyre monkees to fit a new pair.
If i paid more attention then i'd swap them round and get more miles (and fun) for my money.
