Drew,
What vehicle are you installing the P4 on? I just installed them on my 04 Altima in size 205-65-16 which is what came on the 02-04...05-06 and even the new redesigned Altimas have 215-60-16. (17's are an option on all years that I mentioned). I like them OK! But, although their not noisy just yet, I've had quieter tires. They may get noisy as they age, who knows. The size Im using looks too narrow compared to other 205-65-16 tires. I was a little shocked when they were delivered from discounttiredirect. I could have installed 225-60-16 as my factory steel wheels are 6.5x16. But, Im only using them for the winter to save my 17 inch wheels/tires(after market) that I use in the summer.
Thus far they are decent riding and not too noisy, corner great and track straight. They seemed to balance well without having to return to the shop for a rebalance. I love the tread design and according to readers surveys, for an all season tire, they do well in the snow/ice which is what I'am looking for. The side wall design is very plain looking and the tread/carcus of the tire doesn't have a square sholder look like a performance tire. The P4's score high in testing and readers surveys but you may want to actually see your size before purchacing them. I sure that some sizes look different.
