Solution 1 - Michelin PSS/PS4
20x9.5 +20
20x11 +40

Solution 2 - RE71-R
19x9.5 +20
20x11 +40

Whatever you do don't disgrace your M with Hankooks

Haha thanks for the advice! ok I hvnt been able to decide for days so I'm just going to based off of the best tire option for me which looks like the RE-11. 265/35/19 and 305/30/19. Now I just have to figure out the best rim specs to get perfectly flush without rubbing. 19x10 and 19x11.5 should be good widths I'm thinking but have to figure out offset

This is my old car. Tires are RE11.

19x9.5 +20 265/35/19
20x11 +40 305/30/19

Wow thank you so much I really appreciate it you just saved me a lot of searching time. You didn't rub on that setup right? I'm thinking to maybe go 10" in the front in case I wanna fit a wider tire in the future and reduce the stagger but I also don't want it to be stretched when I go 265 this time around

If you want the bigger diameter in the back, go with 19x9.5 front and 19x10.5 rear. I think this is a better spread on the widths anyways. The concavity will not change between a 10.5 and 11.

With the 9.5 and 10.5, you can run 265/35 and 285/35; this will give you the diameter spread you want.

OEM rear is 2.5-2.7% taller than front. 265/35 and 305/30 has 0% delta, so your computer will assume your rear tires are slipping in the rear at high speed.

Did you have any twitching at high speed to ECU intervention? 265/35/19 and 295/35/19 (3% delta) is what we recommend unless you code Euro MDM or don't drive pass 100mph. Euro MDM is easy to do.

Going 10" on the front with a wider tire than 265 could get tricky. Be sure to take into consideration your suspension mod and whether you're gonna run camber plates or not. If you are dead set on going with a 10" front, offset is going to be key to give you the fitment you want.

Pretty sure you meant 295/35/19. Right?

[ryank382]

A lot of people are running 265/305 with no issues though now I'm getting scared lol. Also I am lowered on KW Clubsports not sure if that matters

I did not but I had Euro MDM. If going 295s in the rear I personally like a 275/30 and 295/30 setup as far as feel. This is what I ran on my BC Forged RS41s. Same offsets and sizes as in my other post just different tires/wheels. Thats a 1% delta.



They do make AD08R in the 275/295/30 setup too for 19s which is nice.

Go with MPSS.

If you do a 19x10 with a 265/35 front from experience is a stretched look with 1 or 2 psi less than the rear would as a result have a .2 smaller diameter than the rear. I would go with a 19x11 rear with the 305/30 and of course run it 1-2 psi higher than the front. I ran 30-31 psi front/rear or 31-32 psi front/rear cold.

I had no DSC/MDM issues whatsoever even on the back roads. They perform superbly.

[ryank382]

I want something better than PSS. I really like all the reviews on the RE-11s it's the perfect tire for what I want but it looks like the best option to not have any issues is 265/285. I really liked the idea of a badass 305 tire though...

If you're on KW CS, you'll have no problem running 19x10 ET20 upfront; even up to 275 sectioned tire. ET20 will give you a flushed look with camber set to -2.0.

I'm running 19x10 ET23 on my JRZ's with a 265 RE11 and it's really tight back there, but I have a few mm to spare. I am running -2.2 camber and the tire is slightly tucked. I could've gone with ET20 to bring it out to be flushed.

See below. 19x10 ET23

That looks great but I dnt wanna mess around with the stock camber settings. Also don't know what tire sizes to get anymore because of this delta situation that you guys brought up. I'm so lost now lol I was in love with the idea of a 305 or even 295 rear

265/35 and 305/30 is fine. I ran it without issues.

Yes, thanks for the correction. 265/35/19 front and 295/35/19 rear.

You mentioned that you had Euro MDM though. Do I need to have it coded and constantly drive in MDM mode?

I dont think so. But this is the first I ever heard of what Signature is talking about. My only concern was to always keep the front a tad bit shorter and not reverse stagger. I heard thats what would mess stuff up.

Well with 265/35/19 and 305/30/19 the front is a hair taller not shorter

That delta thing just threw me off also. Can people explain please :

OEM tire height front is 661mm and 695mm rear (255/35/19 front and 275/35/19 rear). The rear is 2.2% taller than front out of the box.

265/35/19 = 669mm tall
295/35/19 = 689mm tall
305/30/19 = 667mm tall

If you go 265/35 and 295/35, then rear is 3% taller. Within 1%, ECU won't intervene.
If you go 265/35 and 305/30, the front and rear is nearly the same diameter. At 100mph, your rear wheel is spinning 2.2mph faster than the front compared to OEM specs. So your computer thinks your rear wheels are slipping, so it will attempt to reduce power to reduce wheel spin (not ideal for high speed use). This is the "twitching" some described at high speed with incorrect after market setup. So coding Euro MDM and run in MDM would help or turn all nannies off at high speed (I don't recommend unless you know what you're doing).

You "could" do 275/35 front and 295/35 rear, which puts the rear close to stock at 2% larger than the front. However, not all tires are created equal. MPSS 275/35 are wide and "might" rub while Pirelli P-Zero 275/35 front are narrower and won't rub. If you go 275 MPSS, then you must be prepared to make minor camber adjustments to prevent rubbing.

Wow never knew that!!

What would you recommend for the 20" setup in terms of tires? What sizes front and back. I'm thinking to go with pss or cup 2s.

Btw I ordered a set of Singature wheels sv302
