Yes, replace the timing belt as preventive maintenance. This is an "interference" engine which means the open valves and the pistons occupy the same space, just not at the same time. If the belt breaks, the open valves will be hit by the coasting pistons and will be bent.
As an alignment specialist at a very nice Chrysler dealership for nine years, I never looked at the sticker on the door for tire pressures. For liability reasons that recommended pressure had to take into account any replacement tire you could buy. I went by the maximum pressure listed in tiny numbers on the sidewall. You'll have to look closely to find them but they are there close to the wheel. If it said "35 psi max." I made them 35 psi. If it said "44 psi max." I made them 40 psi. Never had a complaint of a rough ride and solved one person's complaint of "hard steering" by raising the pressure.
44 psi tires run very nicely at 40 psi. They would be under-inflated by over 20 percent at 35 psi but if the manufacturer put "40 psi" on the door sticker, some people would follow that after buying tires rated at 35 psi max. That means the sticker would have them over-inflating their tires.
