It wasent the tires that caused the rub, it was the 4 1/2" backspacing on the wheels. The tires fit fine with room to spare. As far as the rear, I screwed up. When I got the 9", I had the rear lengthened by 1/4" on each side. Sorry bout that.
I have mocked them up on my car and asked the same question while doing it not too long ago. My conclusion was that 4" to 4.25" of backspace was needed. The tire is tight, but will go with the right rims as attested by responses to your thread and different respondents to my thread. IMO 7" rims with 4" B/S would be best for 275/60s. The same rim would also easily accomodate a 255/60. That is the route I am going... the 275 is only slightly wider and an inch taller, so I can lose a little width, IMO the 275 is too tall. My car sat with them on there a couple days and I just couldn't get used to the extreme height of the tire compared to the rest of the car and the front tires. Add that to the touchy fitment... and I go 255/60. Dave
I have 255's on a 9 inch rim, 17 inch but 255/45's are 10 inches wide. I had to roll the fender also. Very close to the leaf & the fender but fit nicely. I will have to take some pics. I had to change the wheel studs to ARP's 3 inch racing studs for the lugs.
NO rolled edges. all stock. I have helper coil springs on the rear. they don't raise the car any, just make up for weak leaf springs.
what can be tucked OK, so we have seen 275s on grabber71s car but they clearly will not tuck into the wheel well. I would like to know what size will actually tuck into the wheel well on say....a maverick with worn out leaf springs to give it the narrowed rear look!
255/60s on 4" B/S 7" rim... 275/60s on 4.25" B/S 7" rims would come very close to being completely tucked. Someone here has 275s on an 8" rim with alot of backspace, I downloaded the pic of his car... The tires are almost inside the wells, that is why I say a 7" rim would do it. 7" is a little narrow for the 275, but it does work. It also gives the tire a fatter appearance. Much like that psuedo-narrowed look you mention. Dave
I used to have a 74 grabber that I put the 4 leaf JC springs on and ran 255 60 15 cragar 8" no rolled lip no rubbing worked great also transfered rear tires etc to a 69.5 again no probs but damn those springs were stiff big difference in the handling though
Man oh man has this issue been beaten a million times. I am running 275-60-15 DR with no rubbing. Rim is 15/8.5 4.75 B/S on a '70. Roled the inner lip SLIGHTLY to accomodate. No rubbing after new leaves stopped the body roll. Scotty P
Scotty are you using a Versailles rear end on your 70? I was wondering was the Versailles width a lil longer.
they fit much better than I anticipated. I have 7 inch rims with 3 3/4 back spacing with 235s with plenty of room. Thanks for the pics, they are great
