15 inch wheels on my Barracuda

I have a stock 69 Barracuda with original steel wheels and stock suspension. I have been running 245/60/14's without any problems. Clearance and driving is OK both front and back cornering and at 80mph. The steel wheels are small bolt pattern with 4 inch lug spread.
Question is the rear wheels a tires: I want to change the rear stock looking steel wheels to 15's and tires keeping the small bolt pattern. How big of a tire size can I go without doing any body or suspension modification? The car is a daily (summertime) driver with a stock factory 340, 4 speed, open rear and stock duel exhaust. Never at the track and no intention to ever modify for high revving performance. I want to "just" give the car a beefier look both in height and width. I'm clueless about the back spacing . Someone has successfully done this before me. OK to send me part numbers from any of the major catalog companies or referrals to any A-body Barracuda parts suppliers. Overall I want to keep the original painted steel look of stock with dog dish covers. Thanks in advance. dg

You can run a 15" rally rim on the front & back.Usually they are 7" wide and have a 4 1/4 back space. You will have to stick with a 65 series tire because a 70 will rub in the front. I run 235x65x 15R in the back and 215x65x 15R in the front with no problems on a 68 barracuda, summit has the wheels for about $105 a piece, center caps are extra, hope this helps.

Wheel Vintiques makes stock looking small bolt pattern 15" wheels in several different widths. You can buy them from Summit, Jeg's or direct from Wheel Vintiques. The size tire depends on how tall/wide you want to go. I have seen 275/60's on stock Barracudas with the right offset.
