**Bike:** *Giant ATX 27.5 2 (2016)* - Hardtail

My current strategy to going off curbs is nose diving... I know, the best.

My current strategy to going up curbs is barely lifting my front wheel onto the curb and than just letting the back wheel smash into the curb hoping it rolls onto it... once again, not the best.

I'm scared of seriously damaging the bike *(specifically tires/rims)* when I go off curbs.

Could anyone recommend be strategy's to going up and down curbs *(and similar obstacles: fallen trees, rocks etc)*?

And also, is there any way to find out how much PSI is currently in a tire, and what PSI should a mountain bike tire be at?
