I just swapped my stock rims and re92's for a set of stock 16" rims with kumho ecstra 712's mounted on them. I bought the second set a year ago and had them stored on my balcony until today. After the wheels had been swapped, I realized that each tire only had about 10-15 psi of air in them. I had paid to have the wheels balanced as they were put on. Does their being underinflated effect the balancing process?
