How much tire clearance

[MrQuick]

Interesting.. What happens on the inside that needs to be looked at. I was thinking the outside would need more clearance with body roll due to the longer stroke. It being further away from the pivot points. It seems like it would move more. Or angle out more. Curious to learn some info. Some new suspension travel knowledge is always welcome.. So, the inside gets some funky stuff. I wanna know the funkiness My car is kinda funky anyway. Id love to trim some of that down. Oh, and Im not trying to be a smart azz if it comes across like that. Just curious. JR

I know, me too, LOL, but you know me by now.

You figure in a turn the body is leaning that way. The inner wheel/tire is getting unloaded and the body rolls. Basically body is then out of the way so to speak. Bottom of the tire/wheel is being pulled at the lower section slightly increasing clearance at the top.
The most force you can put on a tire is on the outer wheel/tire which in turn gets real close to the inner wheel well. Much more so on a car equip with a 60 series tire over a 30 series. But rims do flex too. Tire/wheel is being pushed and will roll inwards decreasing clearance.

A well sorted out car can control the roll and minimize tire/body contact. See how a proper rear bar and or lateral locating device can help control the body and suspension.

I am not picking on anyones car or passing judgment, those were just the best shots I could find.

My 78 TA with 275/60-15s and a hard body roll(slant driveway) would rub on the inside even with probably over and inch clearance when level due to the solid rear axle.
