Cadillac's New Bolt Pattern 5 x 114.3

SoCadillac · #1 (**permalink**) 01-21-06, 09:17 PM

Well, Wheel Warehouse had a manufacturers show today and my wife and I went. Man, it royally sucks when every vendor there had absolutely nothing for our CTS's with our 5x115 bolt pattern. There were some drop-dead gorgeous new wheels, and new great three piece wheels. We headed directly over to the BBS rep and asked about any upcoming 5x115 BBS wheels. Answer: No. Reason: Sticking with the more popular bolt patterns. All the high-end reps said that thought what Cadillac was doing with the Sigma design Cadillacs was great, and would love to make wheels for them, but not in the 5x115 patterns. So here is my idea: When Cadillac either spins-off as a separate entity or after the reorg, Cadillac needs to make a wheel pattern of 5x114.3 at the very minimum, and dump the 5x115 pattern. They had some nice rides there and the biggest kick was an older couple tricking out their new Scion with the latest aftermarket wheels.

Thats weird. My dad and my brother got 300C's and they have told me that the 300 has a 5x115 bolt pattern. Its not just the CTS with the 5x115 pattern. My brother is all into mopar vehicles and he told me that most Chrystlers are 5x115.

I specially asked for 5x115 and never mentioned the Cadillac unless they asked. It would be nice to confirm whether the 300's are the bolt pattern and what wheel offsets the 300's run with.

i'll try to find out from my brother and my dad the offset, but i do know for a fact that the bolt pattern is 5x115 on the 300. They put 22's with 265/30 tires on theirs and they told me the bolt pattern is 5x115.

114.3 is very common, even with a 115 mm you can still run a 114.3, .7 mm is a very slim difference. , you might need some hubcentric rings at most, usually they bolt right on.
I am willing to bet the 300C does have a 115mm but that they are running 114.3 rims.

Kael,

Thanks, but no thanks as I have run hub-centric rings (again no thanks) and tolerances are everything when you are talking wheels and parts that use the physics to back them up. When you tighten a lug nut on a wheel it pulls the wheel to center on each of its lug, so the .7 has to go somewhere (some might get lucky and it's equally distributed among the five lugs). Although many people likely run the 114.3 pattern on a 115, it is just not the ticket for me personally, but I appreciate the thought.

Then u pretty much have ur work cut out for u trying to find 5 x 115 bolt pattern aftermarket rims. Most are made to fit a huge variety of cars

Not sure what ur trying to say about hub rings though, yes the .7 as to go somewhere but the hub rings make up the .7 difference so the rims fits properly, that's the whole point. A 5 x 114.3 rim fitted with the proper sized hub rings makes it 5 x 115, so how's tighting the lugs different when rings are used?? Maybe with rubber rings there can be more give at each lug if one lug is tightened more then the other but that's simply solved by torquing each lug to the same ft/lbs or switch to mental rings so there's less potential "give" at the base of the lug. With hub rings mounted the rims shouldnt rest on the lugs, again thats point of the rings, to keep the rim centered and resting on the bore not the lugs.

thats pretty sweet how the don't have prices on their webpage...

Back from the dead...

Anyone ever bring a concensus on this? Will ChryCo OEM 5 x 114.3 mm rims work on 5 x 115 mm GM car?

Found a nice set of 300C 18" rims and pondering for my Buick Park Ave.

Thanks!!

Good question.

IF both the Cadillac and Chrysler wheels index on the center bore (which must be exactly the same ID), then the hardened (!) GM lugs might bend that 0.35mm inward to match the Chrysler bolt circle.

On the other hand, if the Chrysler wheels do not index on the center bore, then the first lug nut of the 5 to snug up throws the wheel center off by somewhere near 0.7mm and you wind up with curious wheel tramp at all speeds because the tire is not rotating on center.

Imagine the geometry. Imagine the possible consequences.

GM has a 70.3mm and ChryCo has a 71.5mm. Seems a lot of websites seem to indicate they do interchange with the larger hub.

Switching GM and Chrysler wheels is absolutely dangerous. I am serious. Check with Tire Rack, Discount Tire, or any other tire/wheel company.

I just googled for bolt patterns:

Chrysler: 114.3.

GM: 115, 120 (certain newer models, and certain ancient models, btw)

GM: 100 (certain small models)

114.3 and 115 do not interchange.

Honestly the bolt pattern is lesser of a concern to me, the hub is the bigger concern, the wheel MUST sit on the hub, it is the load carrier, the bolts simply hold the wheel to the hub. So the 1.2mm slop between the hub and the wheel is to me the major show stopper, it can be corrected, but I am not cozy with it. I know some who even tow with slop in the hub to wheel and I don't like it. Wheel spacers are #1 culprits in this.

yeah GM is retarded thinking they can change the world with their 115... for 2008 they gave up thinking they "rule" the rim sizes and went to 120 which is bmw and others so at least is it moving to a more standard rim. MORONS... I emailed them and they go sorry!

My wheels fit my car perfect just get asantis they build them for you and your car
