265/45/21 tyres. Noisy?

[roverkent]

Hi All,

 

my first post, having returned to Audi after years with JLR.

recently purchase an e-tron Sportback 55 with these big wheels shod with the low profiles. Never had an electric car before or one with low profile tyres so the noise level is surprising ? Any ideas on value of replacing with say 255/55/ tyres on 19 rims? Any ideas gratefully received. 
Can brake discs become noisy on EVs?

Thanks,

No noisier than non electric cars, though you will hear such noises more readily because the drive train is so quiet. Any road noise you hear is undoubtedly as a result of the low profile tyres providing a harder ride. There are quiet tyres available with sound absorbing rubber foam stuck inside the carcass, but they are still new on the market and not yet of proven durability. You would get a quieter, softer ride with a smaller wheel/higher profile tyre, though I can not recommend a specific combination.

Hi Cliff,

appreciate the response/comments. I think quiet and comfort will be the deciding factor ( at least that is what my wife tells me! ) so I will take your thoughts to heart. I have always been a Pirelli fan so may start there when these Bridgestones run off and will seriously check out a smaller rim.

Thanks again,
