Quick question, I had my Nittos swapped onto my OEM rims as I shredded my Potenza's at a track day yesterday (unexpected beautiful day and I have to wait to get in the next set of R2's), (I have NT05R rear and NT555R fronts). Whenever I have used them I have never had an error before and they are typically within 1/2" circumference of front and rears (I have not had a chance to measure the current setup). Should I be dramatically concerned with this (I am wondering if they just filled the fronts to high and hence the variation became too much for the computer). I do not plan on doing any drag strip runs, just want to make sure it is safe to drive home. Right now the PSI is 30lbs all around. I find it ironic that the error occured within 5 miles of swapping the tires.
