Hi Guys! Just had the new Dunlop SP 5000 (225-60-ZR15) installed yesterday on my '89 535iA. I am really impressed by the ride and especially the quietness of the tire, and they handle well also. Thanks for recommending them. Can you tell me what pressures to run on these tires? The maximum inflation pressure is 51 psi. What will give the best ride and best performance for these tires? Thanks again for your help Eddie, and please tell Carol thank-you for fixing the warehouse error. Jr '89 535iA
