Simple Camber Question
Simple Camber Question
(OP)
If non-zero cambers make shoulder wear of tyre (as Fig.), Why many of famous car manufacturers choose a non-zero (almost larg negative) camber for their front (or rear) wheels?
If you tell me they compensate it by toe-in (for example), I'll ask you how?
thanks.

RE: Simple Camber Question
1b) As the vehicle rolls it generates negative camber on the outer wheel. In practice you can't include enough camber gain, especially on rear wheels, partly because this is closely linked to RCH. So you dial in some static camber to help compensate for lack of camber gain.
2)How?
Cos we're clever.

<Maybe I ought to list a "What I know" at each thread!>
My essential question is:
Is shoulder wear a penalty for these tires (aging)? (If not, ...Why...Please...)
And do they use this appreciable negative static camber with a solution for their shoulder wear?

RE: Simple Camber Question
For a radial I think it is about 1:10 ratio toe angle versus camber angle in terms of lateral force.
RE: Simple Camber Question
The differential wear on the tire from camber and toe is to do with which part of the tire is working hard (the obvious shoulder), not the thrust.
