Lol, sorry about the tone! There is just a lot misinformation out there and I was trying to make the point that if you can't get the fitment you want with your wheel of choice, there is no reason to settle if spacers will get you there. Now I agree if you are trying to bridge to big of a gap....that's not good!

Needs more Wheel Gap :ughdance:

Hey Guys!

Loving all of these 18's setups

Im finally in the market to buy a set of wheels but had a question regarding wheel/tire size.

After hours of reading through all the forums and trying to understand wheel specs, I think I finally found a setup that i'd like.

Im thinking about getting the Enkei GTC01RR or RS05RR in these specs

F: 18x9.5 +22
R: 18x10.5 +15

As for the tires, Im looking at two different options and would like some input as to which tire size would work best. I plan on dropping the car on HKS Coils (already ordered) The tire specs I have in mind are

275/40/18
305/35/18
OR
285/35/18
295/35/18

Any help/insight would be highly appreciated!

Either setup will work, I'd opt for the 275/305. 285 is bigger than I'd personally go on a 9.5" but I know people do it.

I would keep the tire width closer to square. I'm not a fan of the extremely staggered setup, but that's just my preference in driving feel.

:iagree:
And now for some maths...
IIRC, stock diameter is F26.9 R26.7

Where desired tire size = (Diameter) x (tread width) R ) (rim size)
For 26" range diameter:
275/40R18 = 26.7x10.8R18
295/35R18 = 26.1x11.6R18
305/35R18 = 26.4x12R18

For 27"range diameter:
275/45R18 = 27.7x10.8R18
285/40R18 = 27x11.2R18
295/40R18 = 27.3x11.6R18
305/40R18 = 27.6X12R18

no matter how you look at it, those 10.5 rims are gonna be more bubbalicious than J-Lo with 305 on them. Good for straight I would think, but would also think gonna have a sloppy handling feel in corners and potential of roll n pop bead

If you are going to lower it too, you could end up with clearance issues as well on your diameter size once lowered

P.S. this site is great! https://tiresize.com/calculator/

I tracked this entire year on a super lowered car (have raised it since just for performance reasons) with a 305/30/19 on a 10.5. Never really had an issue with feel or the bead (looked sweet too). Might just be preference though

I'm running 18x11 square with 315 at the track with no issues. My buddy that runs c6 corvette runs 335 rear and 325 Hoosiers on 18" wheels. He got me thinking, lol.

I'm sure preference is a part of it. Another (BIG) part is 18 vs 19 rims when it comes to those sizes and performance :tiphat:

Now THAT's good info! and rather impressive! that said, longer wheelbase of a C6 I can see how he can get away with it. That of course if my physics brain module is still working right with the silver rum and sweet tea I'm enjoying lol

This what a set of NT01s in 315 look like!https://uploads.tapatalk-cdn.com/201...07a261ce52.jpg
