(I buy Cooper tires - American owned and most are made in the states. Great tires for a competitive price. Mastercraft is another tire line owned by Cooper and many of the tires between the Cooper and Mastercraft lines share cores --> Sensys01 and Touring SLE's mentioned below are produced on the same prod line)
Currently I have Mastercraft Sensys01 in the stock 225/50r17's on the Maxima. I am VERY impressed with their wet and snow performance as well as fair weather driving. They are quiet, have a nice ride and corner well but are not a true HP tire. They work perfect for out 1000-2000 mile road trips throughout the midwest and our daily driving. For an all-season tires, the Sensys01 hold their own and do much better than the Cooper Lifeliner Touring SLE's we had on it before.
SLE was a good tire too but at the end of its life, it was NOISY and did not stick on wet roads and floated in heavy snow. (One evening after work, my wife called from the side of the road on US RT 20 - She said that she was stuck. All the car would do was shutter and there was smoke coming out from under the front of the car. I got a lift to pick her up and discovered the Traction Control got confused. She lost momentum merging into traffic and that was it. I turned off the TC, gave it hell and made it home... but was not fun, even for an experienced snow driver)
Cooper has since replaced the Touring SLE with the CS4 Touring. I have the first set sold in Ohio and they are on the G20 in 205/50r16 on Sentra SE wheels. The tread is a cross between the OLD SLE and the Sensys01. They do a MUCH better job at getting water out from under the tread than the SLE's. Currently have 10k miles on them and this winter has been a real test - the most snow here in 10 years. (25+" from Dec til now, 2-4" called for today) I am very happy with them so far. Not overly sticky but handling is predictable and ride is a nice compromise between firm and squishy. (This impression is based on the same wheels/tires being installed on 2 different cars --> 01 Sentra GXE and 02G20Sport)
Pics of the CS4's are here on my cardomain page for my old Sentra:
