After hearing that Nokian is or has discontinued the G4's we've been buying these up from sites like simple tire and Walmart, plus knowing they're on sale and cheaper than our original set of Nokina, Our basement is looking like a tire shop. I believe the "oldest" tire we have is date coded 4321. The main reason to buy or even replace the ones we already have is that because the suspension was not dialed in, the tires have been making contact with the fender edges and are getting sidewall damage. Now that the suspension has been dialed in.. ther';s no more tire to fender contacts.. but the damage was already done. we'll be replacing the rear two tries this Fri with a set of new ones we got 2 weeks ago. The other 2 tires in the basement will be there when the 2 damaged wheels have been repaired and recoated. all in all this means we have 6 wheels and tires total and may end up getting another two wheels and just have a summer and white set.
All that aside, we've been very impressed with these Nokian G4's, they have a bit of road noise but we like it.. they grip the pavement very well wet or dry. The only issue we've had with them is that these tires do not like the metal bridge edges or metal grooved roads or the painted lines in the road or cross walks. if it wasn't for the fact that we didn't have the suspension dialed in, we haven't had a set of these tires long enough to actually know how many miles we can get out of them. the tires sidewalls ended up getting shredded.
