Tires NANKANG or Maxxis

My 2.3s were 55mm on some wide 1980s rims. I'll remount them on different rims soon and can measure then

My DTH 2.15 looks like about 2" exactly

I ride on a DHR2 rear in DD casing and MaxxTerra compound, and an Assegai front in EXO+ MaxxGrip. Really good combo for the descents but a little bit slow on the climbs.

The Maxxis Ikon in dual compound would be a good choice. It won't have great grip on wet roots or rocks, but sounds like that's not a concern.

Something like a maxxis ikon should roll great on the road and still work on trails.

I’ll probably end up with another set of Nankang AR-1s next.

They are nice tires that roll really well. Mud and other soft ground can be an issue with the low tread and cornering can be a bit iffy with minuscule side knobs and rounded profile.

Ardent rolls well but is lacking in traction. If you want to take corners fast, I would stay away from Ardent in the front - there is a dead zone between the middle and side knobs that will feel vague especially when cornering.

I've had NS-II on my car for the past 4 years. For daily driving these tires will do just fine. Wet grip is alright and they're not terribly loud. They don't compare to Michelin Pilot Sport tires I ran before but they also don't cost anything close to Michelins.

I ran a set of Nankang tires for 4 months. They came on the wheels I bought and they had good tread, so I figured that it would just be a waste for me to spend money on new tires while running these. They are not great - winter traction is non-existent, it was legitimately scaring driving on these tires when it was below 20 degrees outside and my car is AWD so that's saying something too (I didn't die though so I guess it's okay ), dry traction is okay, but tires feel very numb. They ride kind of hard too and are noisy. I do drive them up to 100+ usually. Haven't had an issue so far. I am taking them off and putting a set of Michelin Pilot Sport A/S 3s. I am expecting big improvements. So my recommendation: don't buy them. save the money, use your current set, and when you have enough, get a decent set of tires.
