tyre and wheel law?

[lambert]

hi,

is there a defiinative bit of legislation that stipulates rim width against tyre width?ifnot what are the penalties for failing to follow manufactures recomendations?

cheers.

Invalidated insurance?  Often written on the side wall the correct rim size, so would have to presume that in the case on an accident, and if the insurance inspectors noticed, then you'd be up a brown creak with no paddle in your hand.

Rim width and tyre size are recommendations and would only affect insurance if proven to cause an accident. Having said that if you fit tyres to a rim which is toonarrow (or too wide) any advantage you were hoping to gain would be lost, or even worse end up giving a negative effect on the tyres performance. Tyre manufacturers will never advise anything other than OE sizes and fitments so any changes in this area are at your risk, with the possibility of no payment by the insurance company if they can prove that your mods help cause the accident. This also applies for over size tyres.

ok insurance to one side, would the likes of vosa take exception if i were to get a road side inspection? i know about load index and speed rating and they are both ok on my tyres for my car.

...nothing in this document effects the right of a 3rd party to make a claim...

you'd still have legal minimum insurance cover (3rd party) even if one day you decided to swap your tyres for novelty balloons and rims made of lego.

Speed rating, yes they can do you for that. The speed rating has to be greater than the top speed of the vehicle.

That's why mog tyres are so bleeding expensive.... 60mph tractor tyres.

 As a general rule, you're allowed one size larger than that fitted as standard on any particular wheel. NOTHING narrower!
 In Europe, the tyre speed rating must match or exceed the maximum speed capability of the vehicle. In UK, you must not exceed the speed rating of the tyres.
 Then there are tyre weight ratings!

Citation please.  Sounds brown and sticky to me.
