Tire and Rim Clearance Help Needed

Getting ready to order some wheels for the "A" coupe and need a bit of guidance. Runing a transverse rear spring with panhard bar to cut down on sway.

What would a recommended clearance between the tire and body be? With currant roll around wheels have 1 7/8" between tire and body at closest spot. Tire centre line is 1 1/2" out from centre line of fender. Would like to move the tire in with a wheel with more offset to get it more centred, if possible. Could I get away with 7/8" clearance?

Second question, what is the recommended allowances for radial and lateral run out for a wheel? Want to be able to check new wheels prior to finishing them.

Thanks for the help

Bit of a bump up for anyone that can help.

Anyone with any information that would help?

7/8ths clearance should be plenty(kind on depends on how flexible the sidewall of your tire is) but we run clearances down around a 1/4" on our road race cars with no problem. They corner hard (which maximizes deflection) but the sidewalls are usually pretty short and stiff. I build aluminum wheels, which is a lot easier than dealing with steel wheel stampings and welding, but we shoot for radial run out of .010" or less, lateral run out .010" or less. Three piece bolt together race wheels we tried to keep the radial under .030" (when you stack components and then bolt together you are so dependent on bolt alignment of the components, plus each component has tolerances which stack up.)

 

Might try a search here on tire clearance, **** Spadero has made some posts on evaluating setup suspensions, all good advice too. You could pull the shackles loose and see what body roll clearance looks like. Block things up safely. It would approximate some of the needed "gap" issue.
