Ok so I will admit it now. I know nothing about proper tire size and offsets. I'm getting ready to purchase a set of forgestar F14s in either deep concave 20s or super deep concave 19s. What would be the best fitment for these two rims packages for flushness with no spacers.
) As far as for the front I wanted a 255/40 but this tire would have a taller overall height than the 285/35. So a 245/40 was chosen. Hope this helps. Everything should be arriving around the first of May so pics of install will follow soon after.
I'll explain what I did... I originally wanted 20's. However with 20's you reduce the height of the tires sidewall. That in-turns transfers road vibrations into the car. Now don't take that as you'll have a horrible ride. Just be aware of it. LOL So I went with 19's for more tire. With a lot of the help of everyone in this thread, and self-research, and talking with HRE & Forgeline... I went with 19x9,5 +40 & 19x10.5 +45. This should give an aggressive flush set-up. For tires... Oh man we all were going back and forth on sizing. We all agree a 295/35 "should" fit on the rear but just how flush and how much camber would be needed. So I went with a safe route and ordered 285/35 Michelin Pilot Super Sports. (BTW guys... Read that the PSS run big.

If you want 20s and your camber in spec, my rear setup is about as flush as you can get w/ 295s. I'm running 295/30/20 in back on 20x10 +45. The front I wanted in from the fender to allow for the flatter fender roll in the front. I had some spacers on my previous wheels to flush them but rubbed the inner fender roll & clips too often. I'm back about 8mm from flush and running 245/35/20 on 20x8 +40 in front. For a flush front w/ the same tires a +32 offset would get you there but you will have rubbing issues at S Tech height IMO.

I hope to at least run 285 next time around, it looks like i'm just about clearing 255s atm. Maybe just a tad bit more camber.

Between the Z's fitment research and now the G... You think I'd have this down!
Hi would this fit in this thread?

Specs are front = 20 X 9.5 +13 R-Disk / rear = 20 X 10.5 +16 O-Disk
Work Gnosis -Gs2 in BKB (burning black)
Tires are Hankook V12's 245/35-20 and 285/30-20 my car is AWD. Rear Fenders were pulled about 1/2 cm and running -1.5 camber front and -2.00 camber rear. May lower and camber rears more but I am happy with the setup right now.
Car runs nice - ride is actually smoother that my winter setup on Blizzak's and stock 18's I'm also dropped on BC coils (for the time being - looking into a custom coil/cup kit in the future).
Sorry car was a bit dirty but it is all washed up now!

Since Robert K is the threads' originator (and current president of the fatty club) he's going to be running 285s out back so I'd say your G definitely would get into the club. You get my vote

285 works for me! However let it be known... If I can go wider after my current set-up I am!

. Is your offset including spacer specs?
Thank you!
Thanks!
No spacers. I worked with Ming @ Fizz autosports -Chicago to get the prefect offsets with the ability to run a fat tire and give a somewhat aggressive stance. He assured me that these would fit and they do. He did assure me to run a 265 max but since I am in an AWD car I went with the "safest" rolling diameter choice.
I will be able to post more pictures probably later this week once it stop raining. I will also be adding hubcentric rings sometime down the road so I'll see if I can get my installer to take a picture of the sticker with the size/offsets/disc on the rim if you would like proof as well.

Posted the same side of the car to show the difference sorry they weren't at the same angles.
