For your setup (OP), given that you don’t have a typical interaxle power divider, it’s a good idea to rotate the tires front to back but avoid switching them from side to side. Try to keep the smallest pairs on the left rear and the largest on the right rear. This helps balance out the wear and tear. It's also smart to rotate your tires every 8,000 to 10,000 miles to maximize their lifespan and maintain even wear, which is crucial considering your 65/35 pavement-to-gravel driving ratio. Here at https://stuck.solutions/ you can find a bit more details regarding this question. You might want to double-check your suspension alignment periodically too, even if it’s been recently replaced.

It's actually a good point. I remember how once I almost bought new tyres, w/o checking the suspention. Gladly, I consulted with another mechanic, and he helped me.
