When using a slip on spacer, is there a rule of thumb on how many threads should be engaged between the wheel stud and the lug nut so that it is determined 'safe'?

I was toying with spacers on the Supra at the auto show and thought it was interesting that 8mm spacers were too thick to be able to even start threading lug nuts onto the front studs, and the same 8mm spacers only allowed 3 full turns of the lug nuts on the rear. Obviously not safe, but it brought up a discussion if there is an accepted standard on what is safe.

Before next winter I may be picking up a set of 3mm or 5mm spacers from you to use on the front Subaru wheels to help with inner fender clearance since it has been an issue with the high offset of the stock STi wheels I use in the winter.

Thanks!

I would say 5 threads at a minimum. Toyotas and Mitsus are a lil rough cause the come with a shank style lug nut which recesses into the wheel. Since they have that style lug nut they run shorter studs, in turn making running slip on spacers a lil harder. i have found a stud that i use on toyota/lexus that has the same knurl diameter but 10mm longer, i have had to us them on vehicle with aftermarket wheels. as far as the spacers..we stock 3mm and 7mm so if ya wanna try them out your more then welcome...
