I realise that the maximum towbar vertical (nose) weight is only 120 lbs (54 kg) when using a cycle rack. I've just bought a very nice 4-bike rack that weighs 44 lbs (20 kg) and I've just added up the weight of our 2 adult carbon mountain bikes and 2 small lightweight kids' bikes and the grand total (including the rack itself) surprisingly comes out at 137 lbs (62 kg). So I'm 17 lbs over the limit and obviously a little concerned. Now I see lots of photos of people carrying similar loads or quite possibly much heavier loads in some cases, so should I really be worried about 17 lbs? I'm not expecting Tesla to approve as they clearly state a maximum nose weight, but just wondered what sort of loads people are actually carrying on the X towbar in practice without any issues? I wouldn't be slamming it violently along bumpy roads or offroad, just regular smooth roads and motorways. Many thanks for any info.
