Uh, no I wasn't bring facetious. I wasn't sure what you meant when you said wheel. Thank you for enlightening me once again.

Thank you for teaching me about dragsters, too. You're so right; I've never noticed the caster angles they use. I guess they don't care about tire wear! Do you know what toe angles do they use? I wonder what causes most of the tire wear on a street driven car, though.
