I have no clearance issues with the 255/60 15's. But I have major suspension upgrades, which gave me room for error in ride height adjustments. Have not gotten to the stock version car yet so I do not know what issues I would have there. Now I am curious if it is gonna be an issue.

Just thinkin guys. I saw a post about spare tires. One of you said Gm would not have made it so the flat wouldnt fit in the tire tub. I tryed real hard and a 225/70r15 wont fit. HAD TO GO IN FRONT SEAT. I was mad too You know a flat never happens at a good time.

Charlie, the tire tub on our Sharks have to be adjusted down a bit to fit a 225 sized tire in them, but they are all adjustable. In fact, your '81 is easier than my '74 to adjust. From '78 up, the tubs had a slotted front mount for the tub that can be slid down to fit the full-sized tire. The original spare was a space saver spare, so it was waaay smaller than the road tires to start with. The engineers designed the tub the drop down in order to fit the road tire in there in place of the space saver.
I had some pics somewhere that showed how to adjust the earlier tubs. If someone here has a '79-up owner's manual, they could copy & post the page in it that shows how to drop the tub down for the larger tire...

Hi ADAM Just looked at my spare tire and read owners book. The book says road tires have to be flat?? I cant see what you are saying. I'm getting a used tub maybe it will work.

Well if you have a flat it will only look odd for a short while.
Barry is right about the indy 500's I love mine. At first the look is a bit different as it not the pinstripe letering look the goodyears were. But the solid look grows on you, and they are rated at the top of the charts. They sure held great with only a 100 miles or so on them when we threw it into turn one at Watkins Glen.....
can you say "sticker tires"
