Squared is preferred... but not on stock, staggered wheels. You are running staggered wheels therefore you need to run staggered tires. When you upgrade your wheels, if you want to run a square setup, make sure they're the same width on all corners.
Yes, 255 is too wide for a 7" wide wheel.

Correct if by "Stock" you mean "Street".
And for good measure, a link to the Street Class rules: https://dk1xgl0d43mu1.cloudfront.net...pdf?1484692275

Yes, thanks, I read the rules for street class.
I was confused because I read in this thread that a square setup with 255 all around was ideal. I did not know why that would be posted if you cannot fit 255 on stock width rim up front and you cannot change the wheel width per SCCA street class. I thought this was a Street/Stock class thread, I am new to autox and these rules, thanks for the clarification.
So I should plan on 245/40 front and 255/40 rear tires to run on stock sized wheels in B-Street class, correct?

Yes
245 front, 255 rear.
245 on the front 7" wheels leaves a very pinched looking tire but seems to be the preferred setup.
The 255 on the rear 8.5" looks just fine.

also I am trying to clarify why it was stated previously that 255 all around would work, why state that if the wheel width cannot be changed in this class, was there a recent change to the rules?
I am not concerned about looks of the tire on the rim, just performance and safety.
thanks

I know about the widths. I am trying to clarify the sidewall size for both front and rear.

If people are referencing that setup in this thread titled "S2000 Stock class autocross information" then they need to stay quiet and stop cluttering the thread.
Rules changed ~4 years ago where Hoosiers/Race rubber was not allowed in Stock class, but the ability to go up or down a size in wheel size(not width!) was added.

I was looking on tire rack and found these wheels that look like they would be legal in B-Street class for the AP2:
OZ Racing Alleggerita HLT
Front 17"x7" 49mm offset
Rear 17"x8.5" 59mm offset

Would these wheels be ok for B-Street class?
