Location: Sydney | Hey guys
Im looking at a set of wheels for my 1960 New Yorker.
Front 255/50-17 on a 8 " rim with 4.5" backspace
rear 275/50-17 on a 9 " rim with 5" backspace
Will these fit without any aggro, rubbing, or disconnecting anything to remove and replace.
Thanks for any help.
Cheers

Location: Southern Sweden - Sturkö island | To each his own, but with a drop of 2", fat low profile tires and oversized rims, the ride might be a dissapointment.
I hear lots of complaint about bad roadability on their GM cars with prarie schooner rims and low profile tires. Youngster like the looks and can tolerate the "exciting driving experience"
I presume that the torsion bars have been adjusted out of specs, so check the camber, it might be totally off with that kind of drop.
Save the original rims and white wall tires, you'll eventually like to mount them again…... |

The camber angles are perhaps too much for low profile tires.
Let's see if Herman kicks in with his experience of the low ride |

According to that site, the rear tires you are choosing are nominally taller but not enough to make a difference. Tape measure the wheel tub and if there is clearance for the width. The fronts are shorter and only slightly wider. You should have no problems fitting those if there is width in the wheel tub. Honestly, I can't remember off the top of my head. |

Location: Netherlands | I can drive all day in and around town with speedbumps and all with the '60 NY and not hit anything underneath.
The rear tires will rub very slightly when taking a sharp corner a little too quickly.
A better front swaybar could prevent that but I'm aware of it and drive accordingly.
My '65 300 convertible has 275/50/17" on the rear-axle without any issues.
Proper wheel-offset is king.

Very nice
Would love to see more pictures, looks great.
The 9" rims have a 5" backspace, the 8" rim has 4.5" backspace.
Would you consider this to be ok?
Stock 6.5" rims Ive got have 4.5" offset.
TIA for any help. |

Location: Netherlands | The backspacing sounds about right.
It's better to have slightly too much backspacing than too little. Too much backspacing can be solved with a thin machined spacer.

Offset? Not possible. Stock offset for these cars is usually 0.5". With 4.5" offset you couldn't even mount the wheels. |

I recall my '64 NewYorker Salon had 6.5" wide wheels on it.

What is the rim width and back space youve used?

Location: Netherlands | Custom widened and backspaced wheel with 9" width. I seem to recall, at the time I made a calculation error and relied too much on the shop's experience doing the widening. As a result the backspacing of this pair of wheels was a little too much, and I had to run thin spacers to keep the tires from rubbing the leafsprings. Been a long time.
IMO Chrysler positioned their wheels halfway in the available wheel-well, so 'usually' the 'proper' backspacing is half the wheel-width, with a little extra added to that. About 1/4" I think. |

The 8's have 4.5" which appears to be what the original 6.5" rims are.
Sounds like it should be about right I hope but maybe the 8's are a bit big for the front?
Many thanks and I love the look of your cars :-) |

Location: So. Cal | I run 8" wide wheels on the front of my '58 Dodge. They are tight, but do work.
Zero offset is where the mounting point is equally spaced inside to outside. Zero offset is equivalent to 1/2 wheel width + 0.5" for backspace. So a perfectly centered 9" wheel would have a 5" backspace.... i.e. 4.5 + 0.5 = 5. |

Location: Sydney | 275 on a 9" rim Cragars worked ok luckily. Wanted 4.4 - 5.0 backspace but ended up with 3.75.
Just squeezed in nicely but would prefer bit more backspace. Plenty clearance on the inside, barely a finger on the outside.
8's on the fron with 235

Havent had it that long but I reckon Ive put about 1000 hours into it so far!
Its mostly stock apart from from dress up bits.
Lots more to do as more funds become availaable, actually, does it ever end? |

In 1960, the roof, front window and rear window was the same for the 4 door sedan and the 4 door hardtop. This makes the sedan appears just as sleep as the 4 door hardtop.
The earlier "turtleback" sedans had higher windows/roof and looks somewhat out of propotion

Location: Sydney | As a bit of an update....
Yeah, I know and expect the "I told you so"
I tried and tried and tried with the 17" Cragars but could not get rid of the vibes or get the wheels to run true once mounted.
Could not run at motorway speeds.
I do appear to have a slightly bent left rear axle but its only a small amount, 0.5mm TIR axial on the mounting face.
Nothing I can do about that for now anyway.
The wheel have been balanced and checked for trueness but I cannot get them to mount successfully against the drum faces.
Ive checked the wheels themselves and they are fine but something is going on when mounting the flat face of the alloy Cragars to the drum faces.
Tried everything.
Re-fitted the stock steel wheels and all is well in the universe and feng shui has been restored again! I dont get it!
Will try again with set of 15" steel rims and see how that goes. |

Location: Southern Sweden - Sturkö island | If the rims have combination slots that will cover several bolt circles (won't fit any bolt circle good), then the center rings is a must (practically a ring that has the rim center diameter as OD and the drum hub diameter as ID with an appropriate height.
I've just made one test ring for Keystone rims on a '66 Pontiac and it's a huge improvement. |

It was a small improvement but only marginal not enough to be acceptable.

Location: Southern Sweden - Sturkö island | I measured one of the Keystone rims;
Lateral throw out = 2,5 millimeter
Radial out of round = 2,2 millimeter
With these "minor" errors, the car was shaking pretty bad in low speeds, but not noticable on higher speeds

Location: DFW, TX | Some thoughts.
Mopars of this era do NOT have a perfectly smooth drum surface. There are rivets holding the hub to the drum, and most (all?) have a locating pin for the factory steel wheels. I have to assume you have removed the large pin but the stamped steel wheels do have raised dimples in between the lug holes that allow space for the rivets. Do your Cragar wheels have indentions to allow space for those rivets?
Make certain the lug nuts you are using are the correct type for your wheels.
If using closed-end lug nuts, make certain they are seating the wheel, and not just seating against the end of the stud!
Check wheel runout on a wheel balancing machine. If that is okay, check for a bad tire(s).

Aren't we talking 1960? In all these years working on 60s I've never seen a drum like that and I've never seen a locating pin on a FL hub/drum either. And never saw a riveted one, like the one you posted, just swaged like the last picture by the OP (use to be). Are you saying this is a 60 Mopar drum?

Location: Muskego, WI | I think the picture with the drums with rivets and locating pin is earlier as it uses wheel bolts instead of studs. Wasn't that the approach for 1957 or 1958 Plymouths? |

| I'd be wondering on tires meeting leaf springs. Cool purple. I once had a '71 Plymouth Satalite Sebring Plus, 440 hp, slap stick yep it was fast. Thing had them little 14" rims. I tried putting in 15" but could not find a combination that would work. Had a set of crager deep dishes, and unless low profiles were put on would not clear fender wells. Sorry but I am not a fan of slam it down with big hoops. I want some side wall flex when me in the go faster mode. |

1coolbanana.... what lugs were you trying with the aluminum wheels? 60 degree taper or?

And was using standard type conical seat lugs.
So the wheel should in theory center with the lugs on the studs.
I actually like the look of those wheels on your car. I wonder if axle runout bad but would be the same regardless of which wheels were mounted. If the wheels fully seat on the drum over the hub... must be in the wheel? Have you tried mounting the wheels on another vehicle and seeing if it drives smooth or not? |

Location: Sydney | Yeah, I liked the look of the wheels but 17's were a hassle to get the correct size tyre, I couldnt get rid of the vibes and so I moved them on.
Im running stock steels and although the rims have the same runout, the big sidewalls seem to take up the slack and its not a problem cruising on the freeway whereas I couldnt do that with the Cragars.
The axle is a problem and is the next thing on the agenda to fix but Im concerned about a way to fix it, depending on what I find when I take it apart.
Parts are non existent here and anything from OS takes weeks if not months even if I can find a replacement part, axle or hub and drum etc that is and I fear it will be off the road for a while if I take it apart.
