1. Nankang SP-7
First up, we have the Nankang SP-7. Nankang has put a ton of research into this tire and it definitely shows. There are a lot of grooves in this tire to help get water out and prevent hydroplaning. The two large gaps that run the length of the tire are designed to minimize road noise and all of the little sipes will allow this tire to get traction in light snow and maintain grip throughout low traction environments. If you think that the Nankang SP-7 fits your needs, you can pick up a set for around $650.
2. Nitto NT420V
The Nitto NT420V is the successor to Nitto's already extremely popular NT420S. The NT420V has large shoulder blocks that allow for more road contact giving you better cornering and dry road traction.This is also a non-directional tire which means you can cross rotate these tires and they wear evenly. This will give you longer life out of your new tires. The Nitto NT420V typically lands right around $850 depending on size.
3. Nitto NT420S
Next, the Nitto NT420S. This is more of a summer tire or performance tire, not something that you are going to want to run in like mud or snow. There are big chunks rubber for really good traction on the street. Warmer temperatures are where this tire really shines. This is also a directional tire so you can kind of see a V pattern. There is a giant cut right in the center which is your main water evacuation channel where if you do end up in some rain it's going to throw that water out of there to avoid hydroplaning. You can grab the NT420S for about $700.
4. Toyo Proxes S/T
Next, we have another directional tire, the Toyo Proxes S/T. The Proxes S/T features a lot of deep siping and overall, just a lot of rubber. This tire is designed to be more of a sticky tire so it will be best suited from warm, summer weather. Consider this one more of a performance tire. If you do a lot of warm weather driving with light rain on occasion, you'll be happy with the performance that this tire provides. The Toyo Proxes line is extremely popular and we're sure you'll love this one too. A set of the Toyo Proxes S/T tires will run you about $700.
5. Kumho Road Venture AT51
Finally, we have the Kumho Road Venture AT51. The AT51 is an aggressive all-season tire that is designed to take a beating. You should be able to see that this tire looks a lot more rugged than the others on this list. It has large tread blocks for road contact, tons of tread voids for water evacuation, plenty of siping and an aggressive sidewall. If you live in an area that gets snow or has harsh terrain, this tire is going to be one of the most aggressive all-season tires you can get. The Kumho Road Venture AT51 starts around $500 a set.
