Wheel/size/offset and tire/size/profile...can be confusing.

I know I know... did you search? yes I did, but I can't find a definitive answer. I'm looking at Front 20x9 +25, Rear 20x10.5 +40. Will it fit? Will it rub?

Welcome. Here is an example of calculating the difference between OEM and your wheel preferences:
Front: Rim & Tire Size Calculator. Custom Offsets
Rear: Rim & Tire Size Calculator. Custom Offsets

I'd get a pro shop's guarantee of a fit before buying anything.

What are the widest tires can be used on stock 18x8 rims? I was thinking about 245/45r18

They’ll fit, but they will poke a bit and rub on dips. I have 20x9 +32 (245/35) and 20x10 +45 (285/30) on stock suspension. Flush fitment with no rubbing over big dips. I added a 5mm spacer to make it 20x10 +40 in the beginning, but I rubbed slightly on big dips so I took it off.

Not sure of widest but I know 245/45/18 should work on 18x8.

245 is perfect on an 8" wheel. 255 is a little wider than the wheel, not sure I'd go beyond that width.

Rubbing on the fenders? On stock suspension? Guess I’ll be rolling the fenders in the future. I got a great deal, but 2 get 2 free.

Yeah, half down the tire wall. With that rear offset you’d probably still rub after doing that, unless you have a bit more camber in the rear, or get skinnier tires.

From the first page, it seems like 285/25 might work better than 285/30 with no rubbing... what are your thoughts?

Rim & Tire Size Calculator. Custom Offsets Haven't you defeated the whole idea of going with 20" wheels? Look at the gap. The rear sidewall is also going to look noticeably thinner than the front sidewall, which will look, weird.

The stock tires are 35 front and 30 rear already... Switching to a 30/25 split might not be that bad. from the excel doc Staggered 20A has that as a profile setting. and Kamauxx is running that too. IDK... I'm on stock height, and didn't think that it would be an issue. Is there a Camber kit for the Stingers?

Oddly, the rear wheels can adjust camber. The front is fixed, and no kits, so far as I have read/heard.

Naw dude, check out my reply to that post on the first page.

Keep in mind, if you go with a 285-25 tire that's a pretty skinny sidewall. And the choice of tires will be severely limited compared to a more common 285-30. Plus, going with a 285-25 would mean the overall height of the setup will be half an inch SMALLER, so even though you're increasing the wheel size you're not decreasing the wheel well gap, you're making it bigger.

Then what’s the best way to avoid rubbing on dips? Not like my town or drives are full of potholes… 285/30 I understand would be best. And yes, 285/25 are only on summer tires.

Is that pic with or without the spacer? I'd love that setup if the rears were tucked in a bit more.

That was without a spacer, so +45. This is what +40 looked like before.

 

[XGC75]

Thanks. I think that's going to be a bit too much poke for me. Thinking I might try the BR14 at 255/35 on 19x8.5+30 Front and 285/30 on 19x9.5+42 rear. I love that dish the BR14 has, just looking to get flush.

Is anyone running?
F:255/35/19 (19x9 ET 30)
R:285/30/19 (19x10 ET 45)

If so, can I see a picture of it?
Would you guys recommend this setup? I'm getting my wheels custom, I'm trying to see if this would be a flush fitment and a lil bit of concave in the fronts

Is your car AWD?

If so you'll need to run 245 35 on the front to match the rear diameter.

Or, you can run a 295 30 in the rear to match the 255 35 on front - I would go this way if there are tires in those sizes.

Yes, I'm AWD. So It'll be 245/35/19 275/30/19?
