17in Tires Noise

I just swithced from stock tires to Konig Tantrums with 205/40/17 tires.
My question is it normal to have more road noise - - kind of humming at low speeds. I had expected to be a rougher ride but was not sure if noise is common.

Thanks Bob

i think ur better off driving to the place where u got the tyres and alloys..and ask them if it's normal..coz they'll know better with their knowledge
