Cadillac Rims on a 4G TL

I've been looking around at some wheels/tires for my 2009 4G FWD - Polished Metal Metallic Body. I think Satin/Chrome would look best with this body color. Anyway. The cheapest I can find with the crappiest tires is like $1500 for wheels/tires/TPMS.

I have found some local Cadillac Rims/Tires that are new that came off of a 2015 Cadillac XTS. Would anyone know if these would work on the TL?

It looks like the bolt pattern is the same 5x120 but that's all they included. I found an XTS brochure and these are the 19 inch and it says it includes P245/45R19. But this is all i can find, don't have anything about offset etc.

I know I've seen a few Cadillac guys in here, anyone know if they would fit my TL? They want $700 for the wheels/Tires together.. And would it be worth it if they do fit...

Hi,
I think you can check out the offset or wheel spec in cadi parts store online, you just look for exactly the car model, then should be able to find the wheel fitment

I've been looking around like at https://www.gmpartsonline.net/ I can find other parts but haven't found any wheels. I'm probably not looking in the right spot.

I did look up aftermarket 19's on tire rack that fit the 2015 XTS, Offsets range from 25mm to 45mm, the majority being 30,32,35mm

Thanks much guys. The link from Anicra says 19" x 8.5". Bolt Pattern: 5 x 120.65mm. Offset: 39mm
the 5x120.65 is throwing me off though, not sure this would work if the TL is 5x120. Although the Info lltfly has is 5x120

From what I've been seeing in the forums 40 would be good with the TL?

I am nowhere near a Tire guy, to be honest I really don't have a clue when it comes to tires/wheels.

you will need to make the rolling diameter of the tire match stock specs.
use a tire calculator. my favorite one is
Tire Size Calculator - Tire & Wheel Plus Sizing

input stock tire specs then input your proposed tire specs.
calculator will spit out if larger or smaller than stock.
anything over than 3% and is a no go

The goal here is to use the original OEM TL wheels and get winter tires for them, and get a new set of wheels/tires for the rest of the year. Looking for the cheapest/best deal on a 19 inch set that would look decent on the TL..

Thx justnspace. Looks like a no go, says 3.89% Unless you think .89% wouldn't make that much of a difference. It seems like there is a lot of space between the fender and tire on these 4g's.

I looked @ Tyre Size Calculator/Tire Plus Sizing Calculator - Tyre Dimensions for Plus Sizing as well and they said -3% to 4% on their site, but when I used their calc it looks like a no go as well... Back to the search for another set elsewhere! Thanks much for the info guys.

You could always go onto Tirerack and put in both vehicles into config. Then see if the rims come up the exact same on the search.

If you put 17in rims on a TL use 245 50 17 , if you use 18in 245 45 18 and if you use 19in 245 40 19. Just like the Acura does.

For sure, if they were the exact same should be all good I guess, but i don't think it accounts for all of the acceptable combinations like the calculator. I had no idea about the +/-3% Hell there is even a Tire/Rim calculator on this site(It's in bold orange under Notices now), so ya I kind of feel like i'm an idiot for starting this thread. Especially being my first thread outside of the new member area. But hey, I learned something in the process so I guess its all good :-D

Check out the AcuraZine Tire/Rim Calculator

This thread was actually useful, imo...you're no idiot.
I'd still go test fit them...I think a % off more than range and you're splitting hairs. Is it just that the speedo might be off?

I'm OK with the speedometer being off a little, will keep my already high mileage car from getting just a few more miles(not like it really matters after 200k, haha). I guess I just don't know of all the downsides to having an oversized tire... Brakes, suspension, hitting fenders while cornering.. I don't want to put any un-needed stress on the car. In the past when I bought used tires/wheels I'd just throw em on if the bolt pattern matched and git-er-done. I really don't know what kind of stress it puts on a car long term, and with my high miles I want to give her every chance to last much longer.. If .89% won't put any stress on it I'd be all for it, but I don't know.

Its about an hour drive there, hour back. All I'm finding local are used BMW rims. I don't even know if these are good enough wheels/tires for the price. My thinking was that its OEM and Cadillac, can't be that bad. I might try to check them out.. What would I be looking for on a test fit? Distance from the fender, wheel well minimum like more than 1/2 inch or so?

Another thing is the 5x120.65 vs 5x120. TL is 5x120 but these may be 5x120.65 I'm not sure how to tell the difference and if they fit correctly. I used to not think about these kinds of things but I've got kids now, weird how it changes the way you think about safety stuff...

I'm almost positive they just shorten them all to 120...
I think you're pretty safe in that regard, they either fit, or they don't...
just need to ensure the hub bore is bigger than honda/acura because THAT would be a show stopper (and it is).
I actually was considering finding some cadillac takeoffs or maybe even bwm wheels to throw on the Caddy...but most offsets are too aggressive...
the V has an aggressive motor but weak ass offsets

Shit, I just realized it's you with the $7000 TL project !
This is well within your wheelhouse!

So did you compare offset of oem TL base wheels and that of the caddy?
I bet it'll work fine.
With a test fit, I'd just say put them on, make sure they fit and aren't 2" past the fender...drive around on them.
Probably will need to swap TPMS to Acura as I don't think those are universal.

Ha ya that's me Here are the sizes that others have found, not sure of accuracy.
TL 19x8 inch OEM wheels are 55 offset, Hub Size 64.1.
Caddy 19x8.5 inch OEM wheels are 39 offset, Hub Size 70.3

I'm guessing I'd need some Hubcentric Rings with inner diameter of 64.1 and outer diameter of 70.3, but I've never used these rings not sure if they would work on OEM Wheels. Plastic?
Hub Centric Rings ( 64.1 - 70.3 ) - Free Shipping on orders over $24 at JustForWheels.com

The offset is 16mm(55-39) difference or roughly 5/8 inch, but the caddy wheels are wider by 1/2 inch. So I guess that is like adding 1/4 inch to the outside and inside of a standard OEM 19 TL Wheel, then moving the entire wheel 5/8th inch more toward the center of the car? So it's shrinking the stance by 3/8th(5/8-1/4) from the outside. And its sitting closer to the center of the car by almost an inch(5/8+1/4).

Looks like the offset and width of my current rims are the same, So I'll have to check on the car later to see if I can go in another inch toward the center of the car without hitting strut assembly or anything else.

Lower offset pushes wheels outwards, not toward the center of the car.

Doh! Yes makes sense. Like 0 offset would be the centerpoint of the Full width. If it were in the center ya it would stick out more. Thanks for the correction. So the wheels would stick out almost 1 inch more, and give me almost 3/8th more room on the inside rim?

There is a calculator for everything.
https://www.1010tires.com/Tools/Whee...et-Calculator#

The math was somewhat correct, and I learned something new about offset.



Or

How the hell can I go from looking @ Cadillac rims to making me want a Cadillac.. Somehow I got into looking at videos of the CTS-V. This is probably old news to some but 640hp in a luxury car from the factory?? wtf I haven't really wanted a GM car since probably the last Trans-Am WS-6. If GM and Cadillac keep this up they might have me converted.

The tires that come with the rims are new GOODYEAR EAGLE RS-A2. Not sure if those are any good, mixed reviews. Considering I'd have to switch TPMS, probably have a shop balance and put them in i'm probably looking @ $900 maybe more. Wondering if I'd be better off just going with a full set with TPMS/balanced/shipped from tirerack. Anything better I could get for a few hundred more?
