2012 Pre-runner sr5 v6 DC SB

Just purchased a 2012 Tacoma last week. Double cab prerunner sr5 v6 at. The truck had 2 miles on it when I bought it. I didn't test drive it on the highway, because I had already test drove a few other ones that day. As I drove it during the week to work I noticed some "vibration" on the steering wheel between 60-75 mph. This is a brand new truck! So I took it back to the dealer and they said one of the front tires was defective. So a day and a half later..They replaced all four tires! The vibration is about 98 percent gone, but it still feels like theres is a little something right around 65 mph. Is there any recommendation on tires that will give me a better ride? I'm looking to upgrade my wheels from the stock 16" base Dunlop tires.. Thanks

 

...probably just a slight wheel imbalance... maybe try checking tire pressure, put to spec if necessary, maybe it'll make the rest fade away.. otherwise, check the torque on the lug nuts - see if they are to spec.
