OFFICIAL: Wide Tire Thread

^ What are you doing in this thread, lambo? Are you lost?

oh lawd, my sides

Eyyo Tacoman, what's the offset, wheel width, and sidewall height of your rear setup.

17x9, 245/40/17 and 255/40/17 rear. Offset 10 front, 20 rear. However with the new wide-body until I get new wheels Ill be running Offset 0 in the front and somewhere between -15 to -20 in the rear.

:up: Thanks, man.

The plan for the track car is to run R888s in 255/50r16 without flares.

Anyone have any ideas on offset for a 16x8 or 16x9 wheel?

Man, thats a pretty tall tire, why not 245 45 16? I have these on 16X9 on the back of my 911. Let me know if you want actual dimensions measured, it's a big tire.

My main concern was with rim width vs tread with.

I want to run the widest tire possible, as the car will be fighting for traction either way. Thus, running a 16x9 would 'in theory' allow me to run a 255 without the tire being 'lazy', so to speak. I'm not terribly concerned about the gearing difference at the moment, as I still don't have a definite rear ratio picked out.

The tread width of the 255/50 is .6" greater than that of the 245/45, however, the 255/50 is comparable to a 26" slick, while the 245/45 is closer to a 24".

If I only had the option of an 8" wheel, than the 255/50 would be completely out of the question compared to the 245/45, however, I'm wondering if the hint of stretch of the 255/50 on the 16x9 would make it respond similar to that of a 245/45 on an 8" wheel, thus allowing me to keep response while gaining tread width.

Do you have any pictures of the 245/45 on the 16x9 by chance?

245/40/17 bfg sport comp 2
17x8.5 et15

I'll try and get some better shots when it is light, i dug these out of my project thread.

My setup is staggered so the two tires on the left are 245/45/16 on 9 inch wheels.



Ignore the massive gouge in the shoulder of the tire.

Heh I'm going to try fitting a 275/40 et street on a 9" pretty soon.
Should be fine but
I will post pics anyways

Are you planning on running a flare?

[spoolinspoon]

16x8 +20 with 245/45 fit in rear with roll and slight pull? I'm going to be in the same boat trying to find a wide tire/wheel combo without getting flares.

When I was really low on h&r race springs, I rubbed with 225s. Flares of some sort are a must.

why R888's, and why 255/50/16? that is way too tall!

[AWDBOB]

Would you suggest a shorter sidewall for track use? I like the R888s for a track car that will only be driven to the track. Would you recommend otherwise?

Also, Lorin, those 245s look beefy! Would you mind grabbing an accurate measurement of the tread width on them?

[nando]

I've honestly really enjoyed my R888s, both sets.
