What is the lowest numerical offset for an 8 inch rim that someone has that doesn't rub. Either 17 or 18 inch.

I want the widest track possible, looking at the cool chart, looks like something in the 20mm offset range would work??

Real important to label threads like this, coupe or sedan. Thankfully your profile says you have a sedan, but not everyone puts that info in their profile. What tire
size would you be running on 17" and 18" rims?

Thanks!

SEDAN, either 245/45/17s or 245/40/18s

Want best SCCA STX performance, can't go more the 245 tire width or 8" wheel width, offset and diamerter are not restricted

Ok, sorry I didn't revisit this post till just now, I do have some constructive imput.

I know from calling Enkei (maker of my rims) that they went out and measured a sedan for fitment. On the rear if running a 9" wide rim and 38mm offset with 245/45-18" tire, that combo allow's a scant 2mm clearance between the tire and fender lip.
Now, what does that mean to you, your planning on 245/40-18 on a 8" side rim. Well, if we take the same offset of 38mm, add the 8" rim, plus the 245/40-18 tire. That combo is 1/2" or about 12mm further inbound. So in theory you should be able to run a 26mm max offset on the rear (I'd consider 30mm as the min, to play it safe. Since the 245/45-17 tire is the same height or rolling diameter, it would be the same. Keep in mind that this only applies to the given tire size.

What about the front, well I honestly don't remember what Enkei said. But I don't think a low offset and 245mm width will work. If I recall they used 225mm on a 35mm offset and I wanna say it was really close. Honestly, my 245's in the front (245/40-18 on 8" 45mm offset rims) are really close to the fender lips in the front. I would not run less than a 40mm offset on 8" rims with 245mm tread width in the front. Enkei's phone number is
1-800-327-2507, give them a call and tell them you were thinking about RPM2 rims for a sedan and you heard they have precise fitment info for the G35 sedan. They are extreamly nice btw.

Here's a web site to play around with to see where different tire and wheel combo's differ in relationship to where they are in the wheel well to one another.

I hope my post was of help to you.

Excellent!

Thanks!

Did a little more research at Tire Rack, they have some 17x8s with a 35mm offset with a recommended tire size of 235/50/17. I looked at the specs for a random 235/50/17 (RE040s) and found a section width of 9.8" and tread width of 8.1 inches (measured on a 7.5" width).

I then went to look up the specs on a 245/45/17 Falken Azenis and found a 9.8" section width and 9" tread with measured on a 8".

This makes me think the 35mm offset would be ok (assuming that the 235/50/17s on the 35mm don't rub!)
