I forgot to thank you all for replying. This thread was unanswered for a few days so I stopped looking. But I see there are a lot of contradictionary statements (it'ok / it's not)
My main concern is if it messes with traction control/abs? Also, is it possible that two 19" rims could have different height with the same tire? I've noticed I didn't mention. My tyres are Michelin 4S with the same profile as touring edition.
