Worcester/Boston Social Thread

Guys run these "staggered" setups on different width wheels on Audi's and the X without a problem but I wouldn't personally risk it.
Off topic: Does anyone have an 9 lip laying around they don't need? Mine is broken and I don't feel like repairing it. The evo's starting to look goofy rolling around without a front lip

The differential isn't going to break (it isn't locked 4wd differential) but it could have a reduce life due the clutches slipping creating more heat. Also the different tires sizes will create more drivetrain losses and rolling resistance.

The aspect ratio (45 in this case) is the ratio of sidewall height to width.
So for a 235 width, you multiply 235x.45=105.75 105.75/25.4=4.16"
For the 255 width, 255x.45=114.75 114.75/25.4=4.52"
So you are looking at a .36" difference in height, per sidewall. Diameters are 25.3" vs. 26.0". And for more proof, you are looking at 796 rev/mile for the 235 and only 775 for the 255 width.
Ok, I am done for now.

They aren't the same diameer 235/45 are ~25.3" diameter 255/45 are ~26" diameter. A 255/40 would be a better choice ~25.0" diameter. If they make a 265/40 that would be almost the same exact diameter.

Actually, this is not correct either

Sorry about the misinfo, I was under the impression that the sidewall was a fixed number rather than a ratio
alright guys don't gotta rip on me for the thought.. haha
You think I could fit 225/45/17's on the stock rims? (Yes I'm trying to use the tires I have right now... hate me all you want)

i'd hope so.
and on the subject of peen, we went to the chicken bone last night and guess who was there....
none other than the girl immortalized in tim's signature. greg got her friend's number :O
