ive been wondering about this myself.. i have an 85 seville same car basicly im picking up my new wheels tomorrow 22" wires..
i went with wires cause what else are you supposed to put on this car? i hate the five spoke look on my cadis.. also i find they are much more adaptaple bolt patterns/offsets.... and this car isnt an easy one to size up.
anyways i am puttting 235/30r22 tires on them they are a high offset wheel with a 4.75 boltpattern on the adapter (knockoffs) the tires measure the same OD as the 245/45r20 tires that the wheel shop told you were the largest you could fit.... the 235's are also "skinnier" than the 245's....
so im not sure why your tire shop is telling you 20's are the largest........ maybe i will find out tomorrow haha but i think i will be fine... i will try to post pics once they are on.
