Why not run the rears at this point too? I've considered the Nismo's, haven't dismissed it yet.

The tires themselves actually recommend -1 to -3 camber to function best. I do plan on autocrossing the car that's actually what my goals are for almost entirely.

Here's a Nismo link

Could run the staggered set, forgot which member did this on a sedan, needed some camber but not too crazy in back.

I'm about to go down to the wheel shop this week and order the wheels and tires, so I'd like to just clarify 2 things on my AWD coupe lowered on Swifts.

1. My front wheels will be 18x8 ET20 with 245/40R19 DWS06 tires. So, right off, I have extended the wheel faces out 23mm, BUT, I am adding a bit more section width on the tire (however, DWS06 seem to be narrower than other tires, for example their 245 isn't as wide as other brands 245's, and usually only slightly wider than an AS3+ 225). My concern, measuring the current OEM 18x8 ET43 225/50R18 Dunlop, I only have about 26-28mm to exact flush (I straight-edged my fender to wheel/tire face and measured) so, my proposed 19x8 ET20 plus a slightly wider tire give me concern. I am very anti-poke. I am thinking, maybe, get a ET40 version of the wheel and use 10mm spacer?

2. I am strongly leaning to a 285/35R19 rear tire on the 19x9.5 ET40 wheel. This does not seem to have any issues at all, and fits your staggered recommendations, and per my fender measurements leaves me with no concerns at all. You said a 245/40R19 on the front wheel will have a little bit of "pinch". Will a 285/35R19 on my 19x9.5 wheels also have a little bit of "pinch"? For the record, I like pinch. Pinch=some basic curb protection.

Anyways, on #1, I would like to get a 245 tire to increase rim lip protection, but am concerned that the tire sidewall may appear "poked" on a 19x8 ET20 front wheel. I have the option with this wheel to get a ET40 for the front, then I could play with spacers....but then I got to thinking about 225/45R19 along with 285/35R19, not ideal but under 1%

So I am hung up on the front wheel ET, 20 or 40. I'd prefer no spacers.

RWD coupes run 8.5 +43 so you'd be 6mm in from that, and going out 17mm from a RWD setup in front should be ok.
Here's a AWD coupe running 10.5 +25 on 275s all around, yours would be about 32mm in with the 2.5" narrower wheel, and 15mm at the tire (from a 275 down to a 245)

I think I am going to pull the trigger on those RPF1's. The weight savings of those + Z1 two piece rotors + Toyo R888's....

Plus I kinda want to run fender flares. Looks difficult to find the right set given the rear door has almost no room. I live literally 2 minutes from a really great auto-cross venue, so that's really where I'm focusing.

The wheels I wanted to order are on backorder of 90 days.

Ended up going to a 20" wheel....
20x8.5 ET40 245/35R20 up front
20x9.5 ET40 285/30R20 in rear

The ET40 leaves me the option of adjusting with wheel spacers, I may just spacer the fronts (10mm)

blnewt, what do you think of the above specs?
I ordered my tires today, I actually planned to order 235/35R20 and 275/30R20 Michelin AS3+, (because I waffled a bit after seeing how big 20's really are) but Discount said they can no longer get AS3+, now there's some new tire out (PS4?) at way more $$, so I went back to the original plan:

20x8.5 ET40 245/35R20 DWS06 up front
20x9.5 ET40 285/30R20 DWS06 in rear

As far as I can tell, everything should be OK on my coupe? My coworker has 285 wide tires on the 20's on the back of his 7 series, and dang 285's look wide (even on a new 7 series), it's got me worried 285 is too wide for my coupe!

You'll be fine w/ those, especially since you're open to running spacers if needed. I ran 295/30/20s on my Sedan, so there's that

Thank you again! I just needed some verification!

RE spacers, you mean just for "flush" fitment, not as in I'll have interference with something?

Hi all,

I'm currently on Verde Axis 20x9 +38 with a small spacer (forgot what size) 255/35 & 20x10.5 285/30 Nitto NT555 G2's lowered on Eibach's. (recently posted on Show off your Sedan's thread)

I just bought Leon Hardiritt Orden's (my dream wheel) that are 19x10 +22 & 19x11 +22.

I decided I want stretched tires on these but not sure how they would fit on my G sedan with this offset.
Looking on TyreStretch.com I was looking to get 235/35 for fronts and 245/35 for rears.
How do you think this will fit? Do you have any tire size suggestions?

Also, will I need to buy any camber kits for front or rear?

Thank you all for your help!

You are probably going to need a camber kit for both front and rear and may need to flat roll the front fender and pull the rear fender. The 10" up front may cause issues with the suspension as well, the 11" on the rear is going to be super tricky too as even 10" on the sedan rear is pushing it... since your stretching it may make some of this easier to deal with, but you're gonna want to test fit especially at the front to make sure you clear the front knuckle..

heres some pics of a 9.5/10.5 in set up for reference with the wheels you mentioned for reference https://www.ravspec.com/archives/5398

I'm currently on 10.5" rears but +45 offset & I still have some room from fender to tire. I guess I will just have to test fit and then go from there. Any tire size suggestions?

That picture you linked is the whole reason I wanted to get these wheels. I've saved that picture on my phone ever since I got my G almost 3 years ago!

I’m running 265/35 on a 19x11. Brands come into play when trying to stretch tires.
