Widest Wheels

I want to get some 18's for my 02 Z28 and I was wondering if I could fit 18x10's all the way around with no clearance issues. I want to keep the rims the same width on front and back but i do want the widest wheels i can stuff under it.

why do you want the widest wheels?

do you auto-x because they only add more rotational weight and affect how your car drives on the street as well as cost more in tire prices depending on make/model.

i've seen 10.5's fit all around with 295 but i'm sure others will chime in.

what kind of backspacing?

i believe they were 54mm offsets. i know that a 18x9.5 with 65mm offset fits with no problem running a 27535/18.

i'm sure someone will chime in.
