Had my lovely new alloys put on the car yesterday kept the original tyres on as they were in such good condition and a good make. All good and really pleased with the look.

However I think they are noisy!! I say think because I'm hearing a rumbling / loud humming noise not the the normal road noise . They are 17" 7.5J the originals FOR SALE by the way were 17" 8J. I've checked the wheel bolts they're fine the tyres aren't directional,

Could they alloys be causing wind noise and the rumbling?
or could they need rebalancing again?
Also is it possible it's the wheel bearings the car's only done 57K and it's not had a hard life so that's my outside guess.

I noticed it straight away on the motorway going home from the tyre fitters.
Thanks
