4th Generation('75 - '79) Wheel and Tire Fitment

I've started this section to make it easier for those that have questions about wheel and tire fitment and what others have used/done. Please post ONLY 4th generation examples of wheel/tire fitment data along with whatever other suspension modifications or not that you have that may affect other members final numbers. Data should include wheel backspace, width of wheel, tire size, etc. Also, please include any pictures you may find that would be helpful. Explanations are great but, as they say, a picture is worth a thousand words!

Please keep any questions about setups in the main wheel and tire section. I'd like to keep the banter to a minimum and just host data and pictures to make it easier to navigate the thread. If you have a specific question about someones setup you see here I encourage you to PM them any pertinent questions you may have.

Thank You!

John

1976 Original 14" rally tires.

I believe I have an original full size spare in my trunk. It is off of a 1976 Medalist package with optional 14 inch Rally wheels (as seen in pics).

The largest common rear tire size for an untubbed 4th gen Novas is a 275/60 15. This size may require rolling the lip or moving the shock inboard depending on the backspacing of your wheels and the brand of the tire. Typically they slide right in with 4.25-5" of backspacing. Less than that will rub the fender lip. A 255/60 15 is a more conservative fit and plenty of tire if you're worried about it.

Fronts - I've run: 225/60 15, 235/60 15, 235/60 14, 205/70 15. Pretty much if the wheel goes over the disc brakes and you pick something around that height/aspect ratio you'll be fine. You might be able to get a little bigger tire but it will likely look stupid.

Remember that 4th gens have a wider front spacing than rear, so you're better off having more backspacing in the front than the rear, using a wheel spacer in the rear, or running a skinnier wheel/tire up front so they don't look like they're hanging out too far.

I can't speak to the larger diameter wheels. I can tell you that our cars work best with around 4 inches of backspacing with a 15 inch wheel. The 3" b/s wheels don't look or fit right.

This is 255/60 15 and 225/60 15.



235 60 14 all the way around with 3.25" b/s.



235 60 15 on the back, 215/70 front on my dad's 75.



295/60 14 on back, 195/70 14 front. They don't fit with 2.5" b/s wheels but I tried.



Same wheels fitting:



295/50 15 DR's. Don't really fit.



Hope that helps.

I'm looking to put 17X8 wheels on my 76 this spring. I tried last summer but the front tire rubbed on the outside side of the fender well. I will have to special order a set of wheels with a 4.5" BS. The ones that didn't work had a 0 offset. Does the 4.5" work?

If you just drove it around it didnt but that wasnt the case with how i used to hotrod it around town. I also lightly banged in the inner side of the wheel well cause they were starting to rub/cut there too on the inside of the rear tire. Nothing touches now. And they fill the wheel wells up nice.
Novageddon responded to wheel and tire size questions I asked in the 4th Gen section.

Here is my '77. Wheel/tire combo fits great with no rubbing issues. The rear will drop 3/4-1" when I put the interior back in, but I do not foresee any issues.

Rear: 15x8 4.50" BS BFG Radial T/A 255/60R15
Front: 15x7 4.125" BS BFG Radial T/A 235/60R15

Yes, this is great. I'm looking for new tires on mine since they're dry-rotted and separating. This combo looks great.

Wheels are centerline lazer IIs, tires are NITTO NT555s. 245/45R17s on 17x8 with 5" BS up front and 275/40R17s on 17x9.5 with 6" BS out back. So far only a small rub on the inner portion of the rear passenger wheel well. It has about 0.5-0.625" of clearance on the inside, so this was from either articulation or axle movement. I'm thinking articulation is more likely since I was going only on straight roads. I know it isn't the best thing to do, but I'm ordering a 1/8" spacer that should take care of this. I verified I will still have 1/2" of threads engaged in the lug nuts even with the spacer.
