Hi guys, so lately I've been noticing that when I leave for work in the morning, there is a shaking/vibration for about half a mile to a mile. It stops after that and evens out. I have fairly new tires all around, new pads on the front, but I haven't yet done timing belt and waterpump. Currently at 102k miles. Any ideas?

could be your new tires are flat spotting over night?

When i say new, the fronts are definitely newer than the back. The front tires may have 1k-2k miles on them while the back have approximately 8-10k on them. The front are Hankook Ventus v12 Evo while the back are Nexen 3000 series. I noticed that the front seems ALOT more soft than the back. Any experience with these tires?

x2. I even went as far as replacing an axle and the issue still exists.

If they are flat spotting, is there anything I can do other than drive it more frequently? Is that bad for the car?

Not bad at all, it just takes several miles for the tires to regain their roundness. what air pressure are you running?

Strange, the place that put my front tires on must be stupid. My front's are running at 33psi where as my back are running at 24. My front tires support a heavier load, but i'd never even get close to the psi limit (max psi for front is 55, back maximum is 44). Whats optimal?

I go by the sticker in the door jamb. 32/32 PSI.

24 in the rears is too low.
