- Roof rack weight limits.
Can depend on a few things I suppose – its not necessarily a worry that the car will just collapse under the weight – these days you’d expect NCAP rated cars to be pretty tough. However it can be a measure of the strength of the fixing points – if you’re roof rack attaches the car’s roof rails those rails themselves might have a pretty flimsy connection to the car.
The other issue though can be to do with the dynamics and safe handling of the car. Landrover put pretty modest load limits on roof racks for some of their models – but thats because they’re already pretty tall and unstable vehicles- so they’re not going to recommend putting a lot of weight penduluming about so high up.
Its all pretty nominal though. The weight is only a small factor in the loads and forces the rack will experience – the wind loads and twisting forces on whatever you strap to the top of the car will often be more significant. The forces associated with the ladders I have on the roof of my car will be much more than the 10kg they weigh would suggestPosted 10 months agoSaxonRiderSubscriber
I can offer no scientific response except to say that I agree with you, and when I had a VW Polo that also had a very low weight limit, I tended to just pack what I normally would in terms of gear – on the basis that everyone seemed to and survived.
Please note: I am neither an engineer nor a physicist. I tend to make decisions using the Force.
EDIT: I wrote this thinking that no one else was responding so I would bump the topic up. Turns out proper advice appeared before I finished typing.Posted 10 months agothisisnotaspoonMember
What mac’ said, it’s not the risk of crushing the car it’s the risk of it flipping over.
I asked Ford if my c-max would take the weight of a roof tent, their response was that yes the published limit was for dynamic stability but they couldn’t put a figure on a load whilst stationary (roof tent plus 2 campers could be well over 200kg).Posted 10 months agoglasgowdanMember
I just used my roomster to bring back 10x 2x4x2.4m planks, I guess around 10kg each, so 115kg or so all in inc. the rack (which still had two thule bike racks clamped to it). I didn’t die.
I wouldn’t worry about keeping under the weight limit. You know what litigation fear does to common sense these days.Posted 10 months agotomdSubscriber
My dad is an avid sea kayaker, those things weight a tonne and cause loads of drag on the roof. He bought a new car last year and loads of models were ruled out because of roof rack loads. Even cars that have rails now either have a) very short useless rails or b) low weight limits.
He ended up with a Yeti – the limit is 75kg I think and the rails are properly long. So maybe worth looking at some of the VAG cars if you haven’t already.Posted 10 months agoDickBartonMember
The roof bats may be rated for a weight, but the roof itself will have a weight limit as well. I have some Yuro roofbars with a weight limit of 90kg, the roof has a limit of 75kg (evenly spaced across the roof, so 37.5kg each bar) so check what is being read is for the right thing.Posted 10 months agobensalesMember

I’ve got a Jag XE and think the load limit on there is only 50kgs. Not sure if that’s to do with the the strength of the roof, or the poor way the only roof bars that fit it attach.
This got me curious, so I checked my XF. 75kg apparently. I only ever carry one bike on a Seasucker, so not an issue.Posted 10 months ago
