I plan to do a 1000 km bike packing/touring. The route consist of 70% tarmac (transition between towns through jungle mountain pass) and 30% gravel (Smooth,chunky fist-sized, sand mostly to get to my destination like beaches, cliff, waterfall, etc.). climate here is dry all year round. i have 2 options for tire type selection, first one is both tyre using regular gravel tyre (knobby, maybe vulpine or cinturato H), and the second is to swap the front with semi slick tyre (same size, maybe Byway or pathfinder). Main things to consider is:

1. does it change the balances of front-rear grip esp. while cornering and descending (climbing mostly depends on rear wheel traction)
2. how much gains (marginal) do i get from the semi-slick tyre
3. which setup is more efficient overall (comfort, safety, speed, etc.)

I plan to do a 1000 km bike packing/touring. The route consist of mostly tarmac (transition between towns) and gravel (Smooth,chunky fist-sized, sand mostly to get to my destination like beaches, cliff, waterfall, etc.). climate here is dry all year round. i have 2 options for tire selection, first one is WTB Vulpine 700x40 both front and rear, and the second is to swap the front with WTB Byway (same size). Main things to consider is:

1. does it change the balances of front-rear grip esp. while cornering and descending (climbing mostly depends on rear wheel traction)
2. how much gains do i get from the semi-slick byway vs using vulpine??
3. which setup is more efficient overall (comfort, safety, speed, etc.)
4. have you try this setup, if yes what is your take on this setup?
5. should you bring spare outer tire?
