Looking at getting a set of 19" x 8" wheels for my Mk5 Golf ( ET50 ) and ideally I'd love to fit some 225/35R19 tyres to avoid any rubbing issues ( lowered car ) but 225's only have a load rating of 88 whereas I'm pretty sure the Golf needs a 91 load rating. Can any advise if this will be an issue? I realise its not legal but how pedantic are the authorities and the insurance companies? Should I take the risk or do you think it would be safe to go for the 235's?

Really? in 19"? Care to name a few? I haven't been able to find any above 88.Originally Posted by Martin

A 225/40 R18 tyre has a load index of 88 (standard load) or 92 (extra load).
A 225/35 R19 tyre has a load index of 84 (standard load) or 88 (extra load).
...
To make it clear, as far as the regulations are concerned, fitting 225/35 R19 tyres on your car will render it unroadworthy.
On a Golf GT TDI with 225/35 R19 88Y XL tyres, you would need to add 0.4 bar/40 kPa/6 psi to the pressures listed on the placard in order to compensate (to some extent) for the reduction in load capacity.
At 2.8 bar/280 kPa/40.5 psi, the tyres should at least be able to support the vehicle's static normal load.
As I understand it, private vehicles in SA do not undergo annual inspections, so if you drive in a cautious and conservative manner, don't attract attention to yourself, and avoid getting involved in accidents, you may get away with it.
Usual disclaimers about taking advice from internet forums apply. Proceed at your own risk. I/we won't be held liable for your actions, etc.

yes illegal.
BUT I have only ever heard of one person getting fined for underload rated tyres (everything else was illegal about the setup mind you (wheel width, offset, rubbing, too much stretch, too low))
and I havnt heard of an insurance company voiding someones claim.
so yes illegal, and yes it could catch up with you. But IMO i think you would be ok 99.9% of the time.

I'm not so concerned about what the authorities or insurance companies might do as I am about the vehicle's general safety and road-holding capabilities - especially regarding the tyre's capability in dealing with dynamic loads and forces.

Unreal - why is this? Side wall height?

What they are saying that you will be ok until perhaps one underated tyre blows out from stress, rolls the car and kills someone.
Insurance company looks at tyre sees it doesnt comply, gets a big rag out and wipes hands very thoroughly.
Probably wont happen but then neither should my wife have cut the sidewall out of a 3000km tyre accidentally

If the width stays (nearly) constant, a shorter sidewall decreases the volume of air a tyre can hold, limiting a tyre's load capacity. This is reflected by the tyre's load index.
Extra load tyres, which are identical to standard load tyres in terms of dimensions, achieve their higher load capacities through higher inflation pressures and its construction.
Aside from any regulatory and liability concerns...
I'm not suggesting the tyre isn't capable, but rather, my concern arises from not knowing whether the tyre is capable (of handling the loads and forces).
It may well be capable - who's to say? (An engineer would be able to tell us).
