Wheel Bolt Pattern: 5x4.5 or 5x4.75

[CTX-SLPR]

Howdy,

Still picking away at my '64 Riviera and it's time to start buying mockup parts. I don't have the budget to buy custom parts to get around the fact the rear suspension has a Nissan 5x4.5in bolt pattern and the plan for front is C6/7 front hubs leaving me with two different bolt patterns. Since one needs to be redrilled, which is going to have a better selection of off the shelf wheels as custom units are almost certainly out of the budget?



Thanks

Prior to switching to metric on some models, GM was the main (only?) domestic using 4.75 for passenger cars. Ford & Chrysler (and AMC) typically used the 4.5" on theirs. Based on that, I'd think the 4.5 pattern would be most common. Although if it's hubcentric wheels then you need to take into account the bore diameter too.

If you know the wheel size & offset you're planning to use, you could search on Summit's website for each pattern size independently; and see how many hits you get. That'd give you can idea whether one is easier to find than the other.

I wouldn't burn that bridge until I had to. It also wouldn't bother me to have two different wheel bolt patterns at all and since most aftermarket wheels are offered in both it really isn't an issue.

I'm not planning on running staggered so having a single bolt pattern will make tire rotation easier but they do make dual pattern wheels though I'm not a fan.

The hubcentric part I'll have to handle with rings in either case. The Nissan centerbore is slightly smaller than the GM but there's enough meat in the GM hub to turn it down to match and stick with a single size. However the Nissan CB is larger than the Toyota, Honda, and Subaru so kinda boxes me out of those brand's OEM offerings which is sad as there are some nice Lexus wheels. The reason for the C7 hubs vs. say a Ford Crown Vic is the Ford hub bore is considerably larger than either the Nissan and GM which would lock out Nisaan, Infinity, and Hyundai wheels. I guess it's no secret that OEM wheels are perhaps more on my mind than the aftermarket wheels at least to start with. I guess I should paw through the Mustang aftermarket wheels as that's probably the largest 5x4.5 aftermarket that isn't "tuner style".

Since you can go both ways on the lug pattern, why not find the wheels you want, then adjust to the wheels? So far as which size would be better, the larger pattern would be better because there is more meat between the holes, so the larger span would be stronger.

You'd have better luck finding budget wheels in 5x4.5" than 5x4.75". I see a bunch of wheels pop up on FB Marketplace with 5x4.5".

So what Nissan rear are you stuffing under this thing?

Sorry for not seeing this sooner. It's a 93 Q45 IRS with a 3.45 LSD. Got it for free out of a friends car he had sitting in a field.

See if Detroit Speed sells their C6/C7 hubs separately from their Alumiframe mustang offerings. They offer both bolt patterns.

so when i was looking for my 72 wheels. I considered swapping to a new bolt pattern cause i really wanted salt flat wheels. That said I noticed in my searches that the most offerings where in 4.75. Seems like 4.5 would be more but that's what I found. It could be the type of wheels I was looking at mostly classic muscle type wheels though. That said its like that with all parts you can find anything you want for a chevy. More commonly than the fords bop amc and mopars. Im not sure what bp a amc uses.

I wonder if they will turn down the hub bore as well? Need to reach 66.7mm vs. the C6/C7's 70.3mm. The brake part is fine Corvette stuff is darn near universal for a wide range of OEM dimensions and aftermarket hats.

I'm going to end up with high offset (45-50mm) wheels to manage scrub radius and track width so "classic" wheels are a bit less of a specific fit as they tend to have fairly small offsets. I am also a massive fan of the "Salt Flat" style wheels as they strongly resemble the OEM Buick Road Wheels on 65+ Rivieras. I have a set of the rarer disc brake versions on my Riviera now to clear the R32 Skyline calipers. Right now I'm leaning towards Hyundai Santa Cruz wheels being an interesting take on the classic design:

Downside is they are only 18x7.5in vs. an 18x8 so narrows less contact patch for the heavy Riviera.
