I've seen some wheels I like 815kg my van is always empty could this 45kg each corner make much difference, I understand the mot factor but thought it was just the tyres they checked not load rating on wheels, any mot testers on here to clarify this ?So much is made on here about fitting correctly load rated wheels, almost to the point of hysteria some might say. Now, I understand the potential implications if something was to go wrong with an incorrectly fitted/wrongly weight rated wheel, but I was wondering if anyone has any experience of a wheel failing catastrophically and causing an accident as I don't think I have ever heard of it happening? I have heard of cheap 'copy' wheels starting to crack, but I believe this is more down to being of very poor quality rather than being under-rated as such.
@Thogg as one of Her Majesty's finest, is this something you have ever come across as I imagine it's a pretty rare occurrence, but the reaction on here to this possibility makes it seem sometimes that fitting a 20kg underated wheel is akin to playing pass-the-parcel with a grenade with the pin out.
I'm not for one second saying you should deliberately fit under-rated wheels, just that the risk may be slightly over-played.
That's cleared that up then never had a class 7 mot vehicleClass 7 mot wheels and ties in my experience
I'm trying to think of an occasion whereby I've been to a catastrophic wheel failure due to incorrectly rated rims. The honest answer is I can't think of one.So much is made on here about fitting correctly load rated wheels, almost to the point of hysteria some might say.

And how many people have ended up with cracked or bent alloys as a result of hitting a pothole at speed? The likelihood of this happening is increased by fitting under-rated wheels and if drivers can miss seeing tyres with pronounced bulges on the inner side of the wheel are they any less likely to miss seeing a crack on the inside of an alloy wheel?So much is made on here about fitting correctly load rated wheels, almost to the point of hysteria some might say.

I am not qualified to answer this categorically, but my rational head would say 'probably not'. I would think that a safety factor will be built into the design of the wheels of at least 50%. The stresses encountered with the wheels are both axial and radial- they need to withstand a fully loaded vehicle cornering at max grip levels so they'll need to withstand more than 815kg per wheel.I've seen some wheels I like 815kg my van is always empty could this 45kg each corner make much difference, I understand the mot factor but thought it was just the tyres they checked not load rating on wheels, any mot testers on here to clarify this ?
Tyres failing, wheel nuts coming loose etc are all far more likely in my opinion.I'm trying to think of an occasion whereby I've been to a catastrophic wheel failure due to incorrectly rated rims. The honest answer is I can't think of one.

I've been to A LOT of those! If I bump into a Collisions investigator tomorrow (see what I did there) I'll ask them..I am not qualified to answer this categorically, but my rational head would say 'probably not'.

Think you need steel rims fish As that game we played dodge the pot holes on the way home from oxford was not nice.Just a case of do it once, do it right..IMO.. totally understand your poiny, but it be my luck and local roads that the wheels have issues under rated..
Plus for me personally, the Van is pretty much loaded up every day.. and roads are very poor here.

That would be interesting to find out!I've been to A LOT of those! If I bump into a Collisions investigator tomorrow (see what I did there) I'll ask them..
