Maybe this is a rookie question but I’m currently building a car and have the following question:
Does the offset of the wheel affect the center of pressure of the tire against the ground? In other words, if I use a high offset wheel and spacers will there be more pressure to the outside of the tire than if I use a more moderate offset where the spokes of the wheel are more on the centerline of the rim?
I don’t think center of pressure will be affected. It comes down to the rigidity of the “tire supporting system”. That is to say, wheel, hub, spacer and studs. If it’s nice and rigid then the force distribution of the tire’s surface upon the track (static situation) should be unchanged.
I read a book on handling the other month and it did not mention a relationship between offest and tire center of pressure. Therefore tire support systems must be rigid enough that it’s generally not an issue.
Of course once you move to a dynamic frame of reference, offset and spacers will change a number of variables, among them increased roll resistance, camber change and center-mass change under roll conditions.
$hit, if I could only “do it” like I’m learning to “talk it”.
