Hey everyone, I have to go and pickup some roof tiles at 5KG each and there is around 90 of them so thats 450KG. Will my car be able to take that much weight in the boot and across the rear passenger seat or should i use a trailer?

i think you may struggle to fit 90 in the back seat and boot. particularly worrying is if you need to stop quickly those in the back seats could hurt quuuuite badly, just something to consider.
if it were me id do a trailer run, however if its close by, maybe do it in 2 loads?

EDIT: missed the fact its a wagon from the title, 90 may fit then but imho still not safely (emergency braking).

Another thing is I guess 450kg is a serious amount of weight, i do not think the rear end is designed to support anywhere near that, you would need to pump your tyres to near bursting pressure etc etc.

That is 450kg over the back of your rear axle, it could also affect steering.

EDIT2: if you go for it let us know how it goes, out of interests sake. all the best :)

I don't see a problem. After all, if you carry 4 large passengers, that's 450 kg easy.
Stack them up in front passenger footwell, on the floor at the rear seat, on the rear seat, then rest in the back.
Engine performance will be ok, but watch out for sudden braking, once the load moves you may be in trouble.

Steady speed, a flat road, and looking ahead in case you need to slow down. Good luck!

All I am saying is exercise caution as its quite different to 4 large passengers sitting between the 4 wheels and 450kg after the rear axle. Picture 450kg trying to "flip" the car over. It wont flip of course its not such a large weight. The front will lift noticeably regardless. Pump your rear tyres to max psi on the sidewall or just a few psi under, again because the load is not distributed over the front axle, its all concentrated at the rear.

If it helps you imagine 450kg better, its just under 23 cement bags of 20Kg each. A fair chunk

Did you read my whole post? 90 roof tiles will take up a lot of room and he will have no choice but to spread them out, roughly where those imaginary passengers would sit. lol

Let's just skip all of this and advise the OP to use a trailer. lol

lollll, its what happens when i try multitasking. selective reading syndrome... haha
yeh makes sense, as does mentioned trailer :P

Weight shouldn't be a problem but it's at the upper end of the scale, best figure I've found (from Red Book) is 468Kg payload for the wagon, presumably distributed evenly from the tailgate to the back of the front seats with the rear seat folded down. Biggest danger is, as mentioned, tiles moving about on braking; unless you have one of those cage barrier things that can be positioned behind the front seats (and blocks anything sliding under the driver's seat) you could be taking a pretty big risk. Un-braked trailer capacity is 500Kg, if it was my decision I'd be hiring a trailer since it's much easier to tie them down and there's less likelihood of being brained when you throw out the anchor.

I've carried 350kg of cement bags in the back of my wagon before no problems. Probably if you distribute the weight more appropriately (ie. in the front passenger footwell and rear passenger footwells) the car won't sag so much at the back. Try to keep the weight in front of the rear axle, and make sure you secure the load!

Use a trailer, it's safer and makes for much easier loading, unloading.

If you don't drive like an idiot it should be fine.. Just distribute the weight as said, pump up the rear tyres to hold the extra weight and brace them up against the seat and the next layer up behind them as much as you can for braking.. Also there's not gunna be the whole 450kgs behind the axle as with the seat down you should be able to load a fair chunk towards the centre of the car.. This will sound odd but Besides the obvious squatting of the rear the extra weight in the rear would actually help with even weight distribution because being a fwd the Magna has 70-75% weight over the front

Depends on whether you want to be careful and safe or - well I do call my wagons the company truck.

Hauled well over 1/2 ton of tiles home for my old flat about 3 Km in a TS wagon it was all loaded in the rear - no seats down - it was *interesting?* when the bump stops tried to steer the rear axle on the bumps in the road but no one died - I should think the newer car will be a much better - but if you're going a long distance - probably hire a 4x4 ute?
