Title: strange rim
Post by: JoeBob on August 04, 2015, 07:29:27 PM
I got 14" rims off of a junkyard mustang. I am happy with the fit. I stripped the rubber to clean them up and found that 3 were 6" wide. One was 6 1/2" The mustang owner needed a replacement at some point. Is this odd wheel going to cause me problems with ride or stability?

How different is the back spacing?  I would say if the wheel is in the back it would not matter.  I would be hesitant to put it in the front.

Thanks for responding. I do not know what back spacing means.

Backspacing is the distance from the flat part of the rim (the part that contacts the disc brake rotor or the brake drum) to the back of the rim. Take a straight edge that can go all the way across the back of the rim ( where the tire mounts ) and then measure the distance from the flat (lug nut holes) to that plate.
That's a bad description. I'll see if I can find a link to a picture.

Try this. It is post number 3. In this picture the backspacing is close to 3 and a 1/2 inches. (I can't really read the tape measure, could be 3.25, but that shows which side to measure.)

The back spacing on 3 wheels is 4 1/8 the odd wheel is 4 3/8. What have I learned?

The odd wheel is deeper so if you were to put it up front there is a potential it may rub when turning compared to the others

Joebob--I have American Racing Outlaw II wheels on my 80 Pinto.
They are 14x7 with 4" back spacing & 215x60 14 tires. had a little rub
on the very bottom of the front fender. A little hammer work & all was fine.
I think you should have no problems with your wheels. Good Luck.

I would put the wider rim on the rear passenger side for a couple of reasons (if I were you and assuming you're using the same size tires on both axles). The passenger rear is usually the main drive wheel on a non-posi rear end. The wider rim will give you a slightly (I do mean very slightly) larger rubber contact patch for a given tire pressure. The sidewalls of the tire are wider apart thus flattening the contact patch (where the rubber meets the road). With left-hand drive cars (American) most drivers corner turning left faster and harder than turning right. The centrifugal force is greater on the body turning right vs. left giving you the feeling that you are going faster turning right even though the car is going the same speed. It is human nature to go slower if it feels faster. If you lived in Great Britain, I would tell you to put the larger rim on the other side because they have the opposite effect with their steering wheel on the other side of the car. The wider rim will give the tire slightly better resistance to deflection or tire rollover and hence corner and wear a little better. Too much info I know but those are my reasons based on physics.
