Listen to the PRO at Discount Tire and keep 'em at 40PSI.
I had the same dilema when I put on my 17"s. I too got mine at Discount Tire and I called them about a week after I installed to ask a 'real person' about the correct PSI. I was told 40.
I don't think that keepin the PSI at 40 would cause the tires to wear faster.
