alignment and camber

[thornclaw]

is there an adjustment to toe that can be made depending on how much camber is dialed in? in a way, increasing negative camber should cause some degree of ‘toe in’ behavior as it causes the tire to turn into the centerline-see pic. i suspect the more neg camber you have, the less toe-in you would need.

Well more static neg camber on the front increases static actual toe, so if you want zero toe you need to adjust toe after changing camber, but you're asking if you need to use more or less toe based on if you're running more or less camber?

So, the toe is measured by the orientation of wheel relative to straight forward (at the middle of the wheel, and at the wheel rim). If the toe is measured zero the wheel will roll straight and wear the least.

Are you asking if the pressure on the inside from the wheel being cambered more causes it to behave like it was toe in? I don't think that's the case, but I would have a hard time explaining why.

the inside radius of the cambered tire is smaller than the outside radius because it’s being compressed, hence it wants to turn inward-like toe does

Interesting.

You HAVE to run toe in or your tires quickly die.

There is definitely a lateral force made by running negative camber due to how the belts are loaded as they roll through the contact patch, but I'm not certain I'd agree with the idea of a variable radius across the tread surface. Camber doesn't introduce a steered torque in the tire, but we might feel one depending on the steering geometry of the car. There is a thing called ply-steer which puts a steering torque on the contact patch as it rolls and this is present on every tire to some extent or another. It's generally something they try to minimize, but I know there are tires which have a certain amount built in intentionally.

We generally run less toe on high camber settings, because it's easy to knock the inner edge off the tire.
