Can I use 225/45/17 on Ap2 V1 front Stock rim in the rear?
My summer set is 215/45/17 and 245/40/17 w Pilot Super Sports on Stock Ap2 V1 Rims.
I got a puncture in my rear passenger tire that is not repairable. I figured no problem I have a set of All-Seasons that I was getting ready to put on anyways. These are 225/45/17 & 255/40/17 (AS3+) on stock rims.. Unfortunately the same rear tire on the winter set is also damaged (outside tread nail). While I figure out how to get this resolved, I was wondering if it is safe to use the front tires in the rear for a few days (commuting in traffic).
So can I use 215/45/17 front (Pilot Super Sport) with 225/45/17 (AS3+)} Rear. The performance of the tires is not that far off. What I am worried about is the the offset difference of the stock front to rear 55 vs 65 and the 7" wide rim in place of 8.5". Will this screw up the ABS big time (like actually cause the computer to get friend or something). Also from a load point of view. Am I destroying the diff\axle by going this route? Again need this for a few days only. Am I taking too much risk here?
Would it be better to run the winter or summer set with one mismatched rear - meaning 225 FL (AS3+) 225 FR (AS3+) 255 RL (AS+) 245 RR (PSS) * <-- The mismatched tire

You'll be fine.
ABS and speed sensor readings are thrown off by diameter changes...not offset/width changes. People use wheels of all kinds of offsets.

The 225's in the rear shouldn't be a problem, maybe drive a bit more careful if you are not familiar with oversteer 
Do not use different size tires on the rear axle (245 & 255) that would be bad for the diff.

The OE tire front and rear outside diameters and hence revolutions per mile are the same so your ABS and differential are unaffected. Not that I'd want to drive much on these tires or or on any miss-matched tires.
The 17" OE 215mm front tires turn 845 revolutions per mile and the rear 245mm turn 843. Two revolutions per mile ain't gonna upset anything. You're gonna need to compare this data to your exact tires -- the data is on the Tire Rack website. I'm running CR-spec 215/255 tire sizes with 845/832 rev/mile without issues. But I have the same tire on both sides of the axle.
Not sure how well front wheels work on the rear and it seems you have another set of rear wheels. A benefit of asymmetric tires ("outside" is marked on the sidewall) is you can swap sides with impunity. If for some reason you now have directional tires (rotational arrow on the sidewall) you'll need to flip them on the rim.

Thanks guys for the quick responses!
Rev 820 / 808
Diameter 24.6" / 25"
So I think the two are not that far off.
I will run the 215/45/17 Front 225/45/17 Rear for a few days, till I get my new replacement tire. I only need this for my daily commute (mostly straight line stop and go, I'll take it easy on the ramps) so hopefully i won't end up in a ditch
I will report back on the thread if I notice anything too crazy about this balance.
