proper wheel diameter for ps2

is 235 35 19 and 315 25 19 okay for awd?
ps2 front is 25.5 and rear 25.2
revs per mile 817 front and 824 rear. so .991
i thought .2 was within spec
is this going to be an issue

225/35/19 will be a closer match to the 315/25/19.

so if the ratio is off, will it be noticeable immediately...
or is the effect accumulative? ie, may take years to notice?

The tire and wheel combination you mention is within spec. If the ratio is outside of spec you might notice some slight handling differences. However the big surprise comes later when your front differential goes out.
