Vubration
Julian: By chance, has it been a while since you rotated the tires? Every ~5-7K miles is recommended. Too many miles in the same position causes uneven wear, until they rumble like off-road mudders on a concrete highway. Old struts and shocks, or a bad alignment don't help. Once worn unevenly, rotating the tires belatedly can quiet them a little, but they'll never be quiet like new tires. Just a guess.
