I just put BGF Commercial T/As on my Bounder, and We're thrilled with them. The first priority was NOISE. And, believe it or not, the nice salesman said they'd be a lot quieter than whatever was on there, and he was right!! Ain't that wierd? The second priority was mfr date. I asked for no tire to be less than 6 months old....they all didn't need to be the same date, but all less than 6 months old. Made a big error in not checking the dates before paying and leaving, 'cause I didn't get what I bargained for, but this was discovered the next day, and they are officially 'used' at that point the warehouse won't take them back (or so I was told). Message there - if you require quiet, recent tires, get something from the seller regarding what recourse you have if they do NOT turn out quiet. You can't tell that till after they become 'used' and therefore not returnable.
