Hey guys went ahead and bought a 23 LT1 i found and cancelled my order since i wasnt prepared to wait so long.

need summer wheels/tire combo and tirerack listed these (in pic) wheels and i am looking to do 305 in the rear if this all works together with my LT1 and do they fit perfectly with no need for spacers or anything?

also going by the decision guide for tires Im thinking of going with pilot sport 4s or maybe the continental extremcontact sport and need to know the size that fits the wheels, i would like to have 305 in the rear is all i have in mind. i want everything fitting nicely.

willing to look at other vendors and choices.

thanks for any help.

Congrats, you have a very nice car

These wheels have non-standard sizes and non-standard offsets, so I suggest that you look around at this site, select your Camaro and see the fitment for yourself: https://www.wheel-size.com/size/chevrolet/camaro/2022/

thanks im really happy with it!

not sure what this means: "These wheels have non-standard sizes and non-standard offsets"

i might be missing something on the link but i should look for these sizes in this pic?

Your front wheels are 20x8.5, offset is +25. The front wheel in your TireRack screenshot is 20x9, with an offset of +20.

I'm not 100% sure, but I think the rears are the same as the fronts on the LT1 trim, so that's another 20x8.5 with an offset of +25, whereas the rear wheel you want to purchase is 20x10.5, offset +40.

These are significant differences and unless someone tried this specific set, they can only make educated guesses based on research, which you can do yourself at the link I provided. Select two sizes, first your front and then another one (doesn't matter which) by clicking on the calculator icons, then click the link icon, which will take you to a comparison detail screen where you can adjust parameters and see the results, the site even spells them out ("... will be x inches closer to strut" etc.). See the green numbers I added, that's the order you need to click on the icons in.

Hope this helps, here are two example screenshots (the second one is just a generic comparison, not for the Camaro specifically):

I knew i had to be missing something and tyvm for the help, i cant make heads or tails of that calculator though and i have to many questions to try and figure it out. maybe i should just try to find a wheel shop and hope they don't screw it up idk

if its this hard to just get wheels i think im going to forget about engine upgrades lol

Those should fit. When I had my LT1 I bought Advan Racing GT wheels


20x9.5 +20
20x11 +35


Used this to make sure it would fit:


https://support.apexraceparts.com/hc...-Fitment-Guide


I ended up trading the LT1 in for a ZLE before the wheels came in but I put them on my ZLE and they fit. I did put a 8mm spacer and extended lugs on the front because the ZLE front fenders are slightly wider.


If I had kept the LT1 the fitment would have worked. According to Apex a 19x11 will work with a +35 or +43 offset. So +40 for the rear is in between the two and should sit pretty flush. The 20x9 +20 you may sit inside the wheel well a little but will still fit.


This is what my ZLE looks like with the new wheels: I am running 285/30 on the front with a 20x9.5 +20 wheel and the rear is 325/30 on a 20x11 +35 wheel

Come on brother, it isn't that hard. You happened to choose wheels that are not made for the Camaro, so while they will most likely fit, I won't be the one to tell you they do sight unseen, then you go buy them and turns out there are issues... If the wheel size calculator feels too complicated, I suggest that you stick to stock Camaro SS, SS 1LE, ZL1 or ZL1 1LE sizes, which are guaranteed to fit and are as follows:

SS
Front 20x8.5, offset +25, typical tire size 245/40/20
Rear 20x9.5, offset +39, typical tire size 275/35/20

SS 1LE / ZL1
Front 20x10, offset +20, typical tire size 285/30/20
Rear 20x11, offset +43, typical tire size 305/30/20

ZL1 1LE
Front 19x11, offset +11, typical tire size 305/30/19
Rear 19x12, offset +41, typical tire size 325/30/19


You can deviate from these of course, but for that you need to understand what you're doing. FYI 3mm or 5mm spacers are the max you can use with the stock wheel studs, if you need thicker spacers, you'll need extended lugs or buy large spacers that include them, and at that point you're very much downhill on the slope of diminishing returns and worsening the car's handling.

oh cool thanks a bunch, i think thats what im looking for.

would the SS front Front 20x8.5, offset +25, typical tire size 245/40/20
diameter match
SS 1LE rear Rear 20x11, offset +43, typical tire size 305/30/20
if they can be mixed matched like that it would be perfect for my style, I drive slow except some strait line short pulls from dig and occasional trip the the drag racing tracks near me.

Yeah, you can use any of the combos I listed even on your LT1, body and wheel well dimensions are the same as the SS.

The 1LE rears you want will be a bit shorter, see picture and info above, you won't have any issues (don't try to put 20-inch 305 width tires in the front, though, and also don't try to mix and match fronts and rears from different configurations )

You're welcome, I'm glad to help when I can (and learn when I can't )

Holy cow, this was unnecessarily complicated! The Ar924s in the OP's screenshot will fit the car just fine. The front will be just like the stock SS 1LE front wheel but with 1/2" less width on the inside and outside, so of course it will fit. The rears are well within the fitment range too: their centers are 3mm (0.12") further to the outside than a stock 1LE wheel, but they are 0.25" narrower on either edge.

Tire selection is a slightly more complicated thing here. 305/30/20 will fit the proposed 20x10.5 rear wheels just fine. The 285/30/20 from an SS 1LE is really a bit wide for a 9" wheel, though: it will be pinched and not ideal. 275/30/20 will fit those front wheels. They're a teeny bit shorter than the 285s, but my experience is that this will not be a problem with the TC/ABS. Another option would be a 255/35/20, which would be only 0.2" shorter than the rears.

I like simple lol, have my cart filled up with those rims and continental extremecontact sport 255/35/20 front and the 305/30/20 rears.

just wondering if they will be shipped all assembled, i dont see it mentioned so im guessing i should ship to a installer? thanks!
