During the summer months, with my tire size (195x55xR15), when I'm either alone in the car or with a passenger in the front, the car is quiet.

However if say 2 people are seated in the back, and i go over a bump (or speed bump) I can hear the rear tires hitting the inside of the wheel well and creating a very quick squeak\screech noise.

When I go back to my stock tire size during the winter months (185x65xR14), I have no problem like the above.

How do people out there with larger rim\tire sizes deal with this situation? Do they have the same problems?

try to see where it's hitting in your fender first.

one solution is to run more negative camber. this problem also depends on the type of tire (widths are different for some manufacturers) and also the offset of your summer rims.

is your ride lowered?
you might have a bit of sag in your springs or you could have blown struts and it doesnt regulate your car on thy up or down during the bump.

You should Check your tie rod end or ball joints. Like my Acura it have a bad tendency to go dry and squeak like crazy at first I though it was the Acura brake caliper, so I change it. If they don't have grease fittings (and some of them don't) shoot some WD-40 or equivalent in there and see if it stops the squeaking. then figure out whether or not you need to replace it based on how much play there is... you probably need ball joints anyway.
