+2 on NRF tires for better ride. I run michellin super sports and keep the donut spare in the trunk most of the time. Haven't had to use it though (knock on wood). Don't know if it was bad luck or what, but I picked up screws/nails twice in the first four months when I was running the stock RFT's - switched out to the NRF michellins and haven't picked up a screw or nail or had any other flat since then (almost two years now).
