>>1749826the qualities that make a tire shock absorbant and good riding, also make it fragile and prone to being cut up on the sidewall by sharp rocks
so 'gravel tire' 'rough road tire' is a complete contradiction and utterly meaningless. You could take tank mode marathon plus tires on gravel (I have) and they will definitely survive, but, the ride quality is awful.
You can take gp5k tires on gravel (I have) and the ride quality, grip, and speed, is excellent, because they're quite supple, but you're relatively prone to cut the sidewall and need to replace the tire (i have), or even just cut up the casing.
gravelkangz are actually towards the fragile supple end. If you want those i'd get the slick ones, the plus model (tougher), but don't try and research them, just get them, because every model of gravelkang you will find people crying about them being fragile which is just what they are inherently and why they're good.
conti 4 seasons is a good middle road option.
Vittoria Pave CG Open is a good risky option
I would buy what you can find heavily discounted.
