Will I have any clearance issue or rubbing issues with Magnum 500 15 x 7 rims with either 60 or 70 series radial tires?
67 GTX

 

???

 

What size are you running now? I would think that as long as you keep the height of the tire and the backspacing about the same, you should be fine. Depends on how much run you have with the fronts wheels at full turn.

 

It can depend on the width of the tire. 60 or 70 series refers to the height of the tire. For those, if any that don't know how to read a tire size -- the first number is width in mm, second is aspect ratio (height of sidewall as a percent of width), and third is rim size.
A 215/60-15 would be lots shorter, 25.2" tall vs a 295/60-15 (not that it would fit on a 7" rim but just an example) 28.9".

 

And a 295/45-15 would be 25.5" tall.

 

on the car now
front: 215/70R15
rear: 235/70R15

there isnt much backspacing now, because of the cragars that are on there

the magnum rims are in more than the cragars, so will the front tires rub at all?

 

So you are just wanting to put these tires, that are on the car with cragars, on the magnum 500 rim?

If I remember correctly the magnums have 4.5" backspacing? You can check to see if the difference in BS would make the tires rub. From a quick check all I could find for an original size was 7.75x14 or F70x14 (which I think is 215/70-14) So to go to your tire it would be an inch taller in the front from what was available from factory. I would venture a guess and say it should be ok, but to be sure just check to see if the difference in BS would make them rub. Or get one mounted and put it up while on lift and turn wheel both ways and see how much room you have.

 

i am still undecided about what tires to put on the car
do you guys think i should go same size all around, or bigger in the back?

 

any ideas?
i am leaning towards bigger in the back

 

I did all the same but was thinking bigger in back would be better. Gives it that rake, but then again I can adjust my front torsion bars to drop it some.

 

what is the biggest tire that can fit on my car with 15 by 6 or 7 cragar's?
the fender well is the stock configuration

 

Just a thought, check the ID of the rims to make sure they clear the drums/discs!

Was thinking of doing a disc conversion, but I'll need different rims as the 15's I have now would rub on the new rotors. Steel rims have a larger ID than alloy rims as the alloy's have thicker walls!

Just something to consider!

 

i did not think of that
the car is four wheel drum
thanks
