Needed to get some good all-season tires for my Miata. I was previously on the original tires (2004 LS) which were basically racing slicks. Had zero traction, and was petrified of driving in any snow. I needed something for the brutal Cleveland winters.
Once the General AS03's were on my car, my new found fear of driving in the snow was gone. I drive carefully in the winter (and like a demon in the non-winter), and as much as everyone thinks a Miata is an awful car in snow, it's 100% what you have on the wheels. These tires are very grippy in packed snow, very stable in the brown slush, and do not waver on the packed ice the freeways get when it's super cold. Yes, you can still do donuts and fishtail around the corners when you want to. But if you are an adept driver in awful conditions, this all-season tire is nearly as tight as the Graspix. I say nearly, because those tires are specifically winter tires and their tread is far more snow friendly.
What I do like about the AS03's is that they are a fantastic middle-ground between winter and summer tires. My previous miata's Pirelli tires were firm, and the ride was definitely abrasive. If you like that sticky, tactile, feel every bump kind of drive, the AS03's are not it. The Graspix were absolutely terrible for summer driving, being very spongy in the corners and just basically a "mushy" drive. The AS03's are right in between; far smoother a ride on dry pavement than the stock tires, but they feel like they handle well in the corners, firm enough sidewalls to take on-ramps twice the speed, but a tread that will let you take that same on-ramp at nearly posted speed in bad conditions.
Granted, I'm only a week in on these tires, I hear they wear pretty quickly, but at this price point it's far easier for me to replace them every couple/few years than ripping through two sets of tires. Summer will tell when I get back to driving driving again, but for winter performance, these tires are very reliable.
