Left & Right rear tires rubbing

Just bought a 68. Have drove it only a few times, have had a little tire rub in the back, mostly the left. Today my wife was riding in the back seat, almost every time I turned into a driveway etc, they rubbed. Either way left or right. The rubbing seems to worse with a passenger in the back. My wife only weighs 96 lbs...
The tire size is 275/60/R15. Can someone tell me what is going on? Both tires have sustainal damage to them?
Thanks in advance for the help,

Re: Left & Right rear tires rubbing

A 275 60R15 tire is a tall tire to start with and with a light spring in the back a little weight will easily put your tire up inside the wheel housing. You probably should look at a 260 or 255 tire. Check your back spacing on your rims before doing so just to ensure its correct.

Smile Re: Left & Right rear tires rubbing

Wrong back spacing on wheels or the tires are too big. I believe 275 is the maximum tire you can have without mini tubbing, but your back spacing has to be right.
Where on the tire is it rubbing ? Inside edge or outside edge ? What is your back spacing ?

Re: Rear wheels rubbing

Rubbing on the outside of the tire I assume? You might have springs sagging. Checking ride height vs specifications would be a good idea. Another question that needs to be answered is what backspacing the wheels have.

That's a wide tire you've go there.
What is the back space of the wheel?
Is the damage on the outside of the tire?
If so, you may need to "roll" the inside of the wheel arch to get more clearance. (I removed some metal while doing body and paint on my 68 just in case I needed a llittle more clearance)
You may need to change the wheel to a more suitable backspace.
You may need to change to a tire that is not so wide.

There are a number of options

Re: Rear wheels rubbing

The only way they will fit is if you roll the lip or jack up the rear. I widened my inners and the 275' sucked right in on a 9'' rim. I have room for a 10" and will be changing this winter. The silver car is mine the purple car is stock inners.

Re: Rear wheels rubbing

do you have a single leaf or multi are your shocks ok check your ride hight .probably wouldnt a bad idea to round the fender lips roll them up check your wheel spacing or offset. air shocks might ashort term cure for new springs but not too much air used them once on mine it rode like a solid axle and then broke the upper shock mounts good luck AL

Re: Rear wheels rubbing

Thanks for all the feedback. I don't understand what back space of the wheel means. Can someone tell me what it is and how I determine it?
The springs are multi leaf. Yes it is rubbing on the outside of the tire. The guy that finished the car left a piece of metal haning down a bit on the inside of the wheel well (both sides) now both tires have damage on the outside of the tire. Again thanks for the help.

Re: Rear wheels rubbing

Re: Rear wheels rubbing

Knowing the backspacing is a good start, but you also need to know how wide the rim is so you have something to reference it to. Which would mean removing a tire and measuring the rim.

In the mean time, can you trim that metal away without damaging the car? That's what I'd be looking into first.
