I agree with FatBoy.
Check the air in the tires.

I tried 2 sets of the valve cap air pressure indicators, so I could walk by the tires and see green stripes on the caps and know the air pressure was ok. Both sets failed me. My brother in law is a long haul trucker, who tells me truckers just laugh at these, as they are more likely to show your pressure being ok when in fact it is low.

Looking at a tire monitor system now, but still just go around checking with a gauge every time I fill up.
