Wheel question..yeah I know...

[Bigal75]

Ok I did search and did find aswers to most of my questions - but I have more.

Guys running 275/60/15's, on 8" wheels with 4.5" backspacing (67 Coronet R/T); how much room to you have on the leaf side? Would a 4.75" backspacing work better? I'm having custom steel wheels made, so backspacing can be anything I would like.

Front wheels, I'm looking at buying some 6" wide Torque Thrust D's when I upgrade from drum to discs, What tire size would work for that size of wheel? I'm looking for something that would look good with some MT Drag Radials 275/60/15.

A 4.5" BS 15x8 wheel will be real close to the "inner" outside lip. a 4.75" BS should work. I tried a 4.375" BS 15x8 on my 67 with a 275/60 tire and it wouldn't work. I ended up with a 15x7 with 4.375 BS steel wheel. Not the optimum size, but it works with my M&H drag radials. For the front a 15x4.5 wheel and a 205/75 tire compliments the back nice.

Wev have been over this many times and some will tell you that they are running 275/60X15" but on a 66-67 you can bet that your not going to be having any back seat passengers or taking any hard turns without rubbing not to mention how hard they will be to install/remove.

I have 255/60X15" drag radials on mine and you have to ligt the body and let the axle hang down and even then it it a tight squeeze.

I was able to get 275/60/15 on an 8" rim with 4.75 BS. Not much room left on either side.

OK perfect. I'll order them up and worst case scenario, I'll have to buy another set of smaller tires.

I have passengers in the back all the time. I do have SS springs, that helps. I will admit changing tires requires lifting the rear high enough to let the springs hang down, but so be it. And the contact patch is enough to lift the front tire with drag radials.

 

[67 B-body]

Are you all refering to coronets, or B-Bodies in general? I dont think a 275 60 r15 would even come close to working in my 67 Satellite! Depending on the manufacture of the tire, they all have a little different listed sidewall width vs tread width. I think some of the 275 tires I've read about, showed a section width of 11.5". That just rubs the springs and or wheel well lip on mine with the Hoosier quick time pro tire listed at 11.5" section width. I was planning on buying nothing larger than a P245 60 R15 "Hoosier 17050QT"or a slick with a max of 29 X 9 X 15, "should be about 10.5 section width".

Of course it does as it raises the rear of the body for more tire clearence and it does it the correct way as in NOT using air shocks.

 

[Bigal75]

For sure I'm not using air shocks. I wanted to get some SS leafs for it anyway. I'll see how it turns out.

Do you have pictures?

Are you running an 8" wheel?

 

[Jeff_383]

No, a 7" with 4.25" BS
