tire size delima?????

ok, I have 275/50/15 on the car now but they no longer make that size in a street tire, I was thinking of putting on 275/60/15 but I don't know if they would look too big. Does anyone have pictures of my similar year with that size? otherwise I will have to go with a drag radial wich I don't want because it rains a lot in the shunshine state.lol

What about a 295/50/15?  If you can go the extra width they are still made by BFGoodrich.  It will also make the tire a bit taller (26.7" versus 25.8") but not as tall as the 60 series tire.  If not then it may be time to change to a larger diameter wheel which is most likely not the answer you are looking for.

What is the width of the rim these are going on?

The overall diameter of a 275/50/15 is 25.83". The overall diameter of a 275/60/15 is 27.99", so you are looking at a difference of 2.16". I don't have any pictures, but hopefully that will give you an idea.

FWIW - I run a 255-60/15 out back.  27 inch tall tire.  Fills the wheel well nicely.



This is the only good pic I have with the new tires.  I'm currently running them on the 10 holes....... I'll be putting them on an 8 inch rim soon....

I hear you on the drag radial, but I can offer a suggestion on a DR which you may find acceptable. 

I have run Nitto 555r's for at least 6 years (on my 2nd set).  I have found them to perform very well in the rain and of course when it's dry (I've taken it on three Power Tours).  It is (IMHO) more of "middle of the road" tire, offering considerably more stick than a standard street radial, but with a "real" tread pattern to drive in most weather (you don't have to worry about snow...).  The life of the tires can be as much as 15k miles, but in reality, if you run them in the rain, they are done in 9k-10k miles (fewer burnouts could give them a bit more life).

On a powerfull car, I have found them to offer an additional safety factor when driving a little harder (the back end is less likely to come around on powershifts or when giving it power around a corner). 

Keep in mind they have substantally less hook than tires like the M/T DR or the new Nitto NTO5R, but those examples have virtually no tread and are pretty scary in the rain!

I have a set of Nitto's for the street and a set of M/T DR's for the strip. 

With the power of your 347, I suspect you may appreciate some traction on the street.

Yeah, 8.5" is a little on the skinny side for a 295.  I am running a 275/40/17 on a 9" wide wheel.  My buddy ran the 295/50/15's on a 15 X 10 Drag Star and it filled the rear on his 86 GT.  Sounds like the Nitto 555r's are a good compromise and they are available.  Cost may be another issue though.

Anyone else run the Nitto's on a car that sees rain?

Not to hijack, but what is considered to be "stock" size in the 15"?  According to the load placard, it's a 225/60-15.  I run that now, but find that my speedo is about 2 mph off (reads high).  Car is the LS which originally had 14"s.  I think if I go up one or 2 sizes I'll get the height correction.  But, I don't want to get too "tall" looking.  I have 10-holes which I think are 15x8?  Or is it 7?  I wouldn't mind trying a 50 or 55 series if I could come up with something that'd work...and not rub...
