Not had a problem with road noise with our various models that we have owned - bumpy suspension perhaps! Last time I had road noise was a long time ago in a Land Rover with very chunky mud tyres (can't remember the make) that gave a loud "rumble", but most modern A/T tyres are no noisier that highway tyres. Any make of tyre will give a certain amount of rumble noise, check out the website
mytyres.co.uk - Tyres for PASSENGER CARs cheap, bargains, look + save where various tests are published for different makes of tyres, including a rating for road noise.
Mechanically, worn shocks, joints, etc can give different noises on different surfaces, so check them out.
Even false teeth kept in a glass in the cup holder, give off a noise on bumpy roads
