What tires are best for pavement? long lasting.

[vidnoye]

It seems that I will need to replace all 4 tires soon.
I believe my kids will do most of their riding on pavement with occasional off road (dirt).

Does it make a difference if I get Turf tires or 'straight rib' tread?
Which will last longer on pavement?

thanks

Slicks are best but, of your two choices, I say straight rib

I was thinking of Kenda or Cheng Shin slicks, they're a pretty hard duro # but they only go up to 13".
