17" x 9" +35 on Swifts... 255/45R17, or 265/40R17?
I'm assuming the 265 won't clear the struts... I'd be ok with running a 10mm hubcentric spacer, but, I don't want them to poke outside of the fenders.
So, even though a 255/45R17 is slightly bigger (2.8%), it'll give the 9" wide wheel plenty of rubber.
Anyone running that size? What tires are you using and do you like them for mild street/strip? Suspension is Bilstein HD with Swift Spec Rs. Thanks my dudes

Run a 255/40 tire & all should fit OK (cant see how the tire will contact the strut spring base in any way
Note: The 45 series is too tall giving a -2.72% speedo error. The 40 series is much closer at an acceptable +1.18%

So, I now note the 255/40s are somewhat undersized compared to stock, meaning a sped-up odometer. Slowed down I can handle
Great website:

First image: stock vs. 255/40 (smaller)
Second image: stock vs. 255/45 (larger)
Third image: stock vs 265/40 (same diameter, but possibly too wide)

So, even though you're on the 265/40 you recommend the 255/40? I dislike the idea of the odometer spinning faster than it needs to, even if it's only 1% more. Buuuuuut I guess over 100 miles, it only ads 1 more... negligible at best.

wow! A 275 seems enormous in these wells. So a 265/40 will fit with no rubbing? I'm seeing the Potenza RE760 in 265/40R17 with a $70 rebate...

After wearing the Nittos out, took a chance on the Federal 595 265/40's & they are great on the street & have the same tread width as the 275's. (nice stiff sidewall)
In your case, running a 17x9 +35 W/a 255/40 you will need to have the rear fenders rolled almost flat. Wasnt sure if you have done that already?

Really appreciate the knowledge, Joe. Tire sizes and offsets are just something I never seem to get my head wrapped around.

Rolling is not needed with this combo in my experience. Even with +5 mm spacers (giving an effective offset of +30 mm), I didn't need to roll with a relatively mild camber of -1.2 degrees. I am running ASUHP tires though, and they are a bit more narrow than a max performance, but I'd think that +35 mm with slightly more aggressive (and appropriate camber) of -1.5 to -2 degrees, a max performance 255 would fit without rubbing.
