ok thanks. that is a big help. 4.25 back space on stock 15 X8. thanks

4.25 back space on a 8" wheel is not enough for a GM A body.. 5.25 is more like it.. The Cutlass in the photos has 15x8 with 5.5 back space.. 255/60r15 tires also..

I would use stock 15x7 rallys with 225/70r15 tires.. The stock wheels are hub centric..

The Parts Place is the only company that sells correct fitting hub centric wheels for the GM A body. They only come in stock steel though..

the car has 15X8 rallys on the back, so I want to get some 15X8 rallys to match for the front

now I am confused. for a 15X8 Gm rally wheel, what is the backspacing? 4.25 or 4.75?

I just went on Team chevelle . those are all conflicting information on that site. so, I am still back to 4.25 or 4.50

stock 15x8'' corvette ralley's measure 4.25''
they will take a 255/60x15 tire easily
for 68 + 69 cars:
a 275/60x15 can work if the outer wheel well fender lip is rolled for clearance
a 275/60x15 will fit with a 4.5'' to 5.5'' back space rim
i've run all 3-combo's on the 68malibuBowtie smiley

15x8 corvette ralleys can be run front and rear with a smaller tire like a 235/60x15
or a similar width 70series tire so you have clearance

oh ok . the seller has 226 60 15 on front and 245 60 15 on front.
well, I just wired him the money and contacted the shipping company. lets hope a 69 Malibu shows up in my driveway sometime soon!

I personally like the style of Rally wheels.

I had the 15X8 rallys I bought from Summit put on 2 weeks ago. I like the look better with the same size rally wheel all around. the tires on front are still smaller, and they are BF goodriches that are 10 yrs old. the standard franchise tire shops wouldn't mess with myk car given tires are over 7 yrs old, so had to go to mom and pop shop. the tires are like new, no cracks, and a lot of tread, so don't want to ditch them. and the letters are white, and easy to clean, unlike the new BF tires I bought new last year for my trans am that are impossible to get white. but, I like the look of 15X8 on all fours
