Often the guys that replace your tyres, over inflate to pop them correctly on the rim. Half the time they don't worry about what the tyre pressure is & are probably just guessing at what your recommended pressure is anyway. Reduce the pressure to the recommended spec's. Many people here run their tyres a few pounds under, some stick to the owners manual. The 1st thing I do when I get new tyres is check their pressure, because they are always wrong.
