Default 235 front 225 back

So a customer threw away some about quarter used potenzas the other day at work so i grabbed them up and threw them on some old rims that i have.

they are 225/50r17 and 235/50r17 so I bolted up the 235 in the front and 225 in the back and measured the circumferences to be roughly79.75" and 79.25" in reality it was much closer to .25" but I'm trying to play with safe numbers.

I figured id have to shave .07962 off the 235 to get them to match.

So the question is, how much will 2/32" affect my center diff? and second would somewhere like discount be able to do this for me?

Thanks in advance, autocross saturday and sunday so trying to figure this out tonight!

Nope. Won't work. Even with the shaving. Plus, with the 50 sidewall both tires are too tall.

Thanks BRO!

You know you're one of my top bros, bro, because you got my back. And I got yours. You're my bro. But you went above and beyond the other night, bromaldehyde. You really did. Saving me that seat at the Velvet Revolver show, even though all those other bros were trying to get up front, bro? So clutch.

You are truly a god among bros.

Just when I think you're as solid as a bro can get, you raise the very definition of brodom to new heights. You're like a brogle, soaring to the farthest reaches of the atbrosphere. Seriously. If it weren't for you and your extreme brobility to hook a bro up when it is most croosh, I'd have been stuck in some bitch-ass seat, cramped all in the corner with a bunch of bitch-asses, bro. But you stepped up. You brovercame all obstacles to help a bro out. This is the kind of **** that makes bros for life.

Brody, I was so stoked when you told Gina to go eat a fat one after she asked if she could have your other ticket, even though you knew you could probably get a pretty deese HJ from her. Bros before hos, bro. That's what I'm talking about.

You are the king of all bros. Brotankhamen. You are the Ayatollah Bromeini. You are Broseidon, lord of the brocean.

But this is just one of many times you've fallen on a grenade for me, brozo. Who took the blame when I broke Skeeter's bong and ****ing Skeeter was all ****ing pissed? You, bro. Who was the first to bro up and carry that ****ing keg of Killian's up four flights of stairs for Duke's surprise party? You, bro. Who was the only Bromo sapien on the planet to tell me he thought the brand-new rims on my F-350 were the **** even though everyone else was all, like, ****ing not that excited about them? Bro, you know it was you. You're my broheim supremo, bro, and don't you ever forget it.

I'm so ****ing glad we're bros, bro!

I've long admired your absolute broficiency in all things bro-related, and the way you've always carried yourself in a brofessional manner. I consider you a brole model. When I was new in this town, you took me under your wing and showed me the bropes. And I will always preesh that. Not only did you school me in proper brotocol, but you were a spiritual leader, a confidant, and, more importantly, a bro. You taught me how to be true to my inner bro and to bros around me. You are a real bro. Not a fake bro, like those other douches. I hate fake bros, bro. Faux breaux. **** that. No, really, bro…you're practically a bro-ther to me.

Look at you, blasting in like Rambro and firing off your launcher like nobrody's business, bro. Serious Brotosaurus Rex action. Brodius Maximus. I'm not big on labels, but you, more than any of the wiggers, bitches, goth chicks, dorks, homos, or Mexicans I know, are absolutely beyond rebroach.

In fact, your brotitude is so brossential that, in many ways, you are the ultimate brototype: You sprung out of the brotean ooze at the very broment of creation, unformed, unmolded, and became the ultimate bro, more powerful than any who came brofore. I don't fear your power, bro, but I respect it. And I will always brobey it.

Brosemite Sam. Potassium Bromide. Brobi Wan Kenobi. Brover Norquist.

Like Broseph Stalin, you are leading the way to the dictatorship of the broletariate. It is truly revbrolutionary. Like the Bro v. Wade of our generation. You brobliterate the enemy from the very peak of Mt. Brolympus. That's some ****. That's brolific. But that's the kind of bro you are.

Bro-S.A.! Bro-S.A.! I'm so pumped right now! Bro-S.A.!

You are the epitome of bro, in every brossible way, and that's the Bro's honest truth, bro. I may have a bropensity for broverstatement, but this no mere hyperbrole: You are 100 brocent, absbrolutely the broest. Brotally.

I wish I had the words to describe what a good friend you are, dude.

lighten up.

It's not just a matter of fitment. They're still two different widths, even if you shave the heights to match. When you have a symmetrical AWD system like Subaru's, you need to keep everything symmetrical and the same on all four corners, including tires. The 10mm difference in width doesn't bode well for the center diff.

That alone should rule it out, regardless of if they fit without rubbing.

You're ruining your center diff every time you drive. What more do you need to know?
