1/4 mile not making sense?? Help!

Had two runs yesterday. First was 15.82 @ 93.8mph. Second was 15.87 @ 92 MPH. I have 17's on my car with oversized tires. 215/50/17, so there off by 4% or so. All variables aside, if I switch back to the correct diameter of tire, shouldn't it drop bother numbers down? I guess I'm happy about the 92/93.8 mph, but not the time.
Short question, By changing to a small diameter (going back to original diamter), what gains/losses whould I see.
Thanks in advance!
