I had to install new rear springs, air bags, and 1/4" spacer to run 275/60/15 tires. The air bags help out alot, you may not need the 1/4" spacer, i had one tire rub on the frame a little.
good luck

I have them on a set of stock T-type wheels and they are on my SS. And have been on my T. In both cases they fit fine, even with the T's lowered suspension. Both cars do have aluminum drums.

I think they should fit...wait for more opinions...think about the speedo error as I noted in the other thread.

I see no reason for stiffer springs...as I said, my car is lowered and I have no problems.

best way is to find a friendly guy at the tire shop that will mount one and try it for fit on the car. 275s fit nicely on 8" wheels with 4" bs on my car...no rubbing either side. (frame or fender lip) Lot's used to say that 3.75 was ideal on an 8" wheel...might get into the lip if not rolled? Best is to try one on your car. :)

IMO, the really hot set up is to have your T wheels widened to at least 8". There won't be the 'bulge' folks are referring to and the footprint is much better. True Design Wheels Inc in Colorado can now widen our aluminum wheels and they do outstanding work.

And if you put those tires on an 8" rim you will need air bags at 10-15 psi. or they will hit a stock fenderwell lip.

i was afraid of them hitting. how much actual footprint on the groung(inches touching ground) would i gain by having them widened to 8inch;anybody know?
ps:i am wandering really if the big concern would be hitting the inner fender well and/or the frame with the t-wheels at 8inchers. dunno

Hank is right that 8" is ideal, but 7" works fine if you keep the pressure above 16 psi or so. As you can see from my pictures, the tread wears very evenly and flat, even on a 7" rim with the 60's.

50's are much more picky on a 7" rim. If I went less than 18 psi with those, the center rib would pick up off the track.

275s work fine on an 8" wheel, but, the back spacing needs to be a bit closer to 4". No problem when having the wheels widened.
