Ive done extra sound proofing in floor and doors..i tried more camber in front..my car is fully rust treated with dinitrol..the best so far is soundproofing floor. But this sound gets in your head so i hear it still..iv have nokian friktion tires on 17inch and its better than 18 with nokian summer. Next i will go for michelin non xl tires..i had this exact sound in a accord type s once but it dissapered when i got lowering springs but i dont know if that helps this time..i think the cavity vibration leads by the front suspension to the floor..it also gets better if you have right tire pressure ,higher pressure more cavity sound..in cars like tesla audi a7 there is a soundproofing material in side the tire for this issue. But there is no tires with this in our dimension..You are correct its more on rough roads. You have done everything? Can you explain what you tried?
