Tell me a bout load ratings ? larger wall heights have higher load ratngs .. Camskill would not return a tyre after some premature damage,It was rated lower than the standard OE factory size tyre .

Would this cause problems with t insurance companies ?

you could make a case of that because the load rating is there to support the weight of the car. Example, 215/40r17 87Y. 87 means a rating of 1201 pounds or 544kg. Meaning four of these tires could support a max load of 2176kg. A fully laden chim with 2 ppl, full luggage and petrol would be at most 1450kg (thats with 100kg people and 200kg luggage!)

They were having non of that ,they would only work off the original tyre load ratings .Seems to me a get out clause .

What about insurance ,could they refuse to pay out ?

The load rating isn't just for static weight though. Under hard cornering, a tyre will experience much more weight than a quarter of the car.

Channging wheel and / or tyre sizes is a an obvious 'modification' that your insurance company would need to be told about. Having a different load index (the Chimaera handbook makes no mention of one) would possibly be covered under the clause of them being appropriate for the vehicle. Just checked my Toyo Proxes and they are 91 at the front and 94 at the rear. When I typed my reg no into http://www.blackcircles.com/general/load-rating those are the load indices returned. Where they get their data is the issue.

That link provided by the OP returns different results that expected. Putting in 2 identical wheel rims with 13mm different offsets returns the information that "Package 2 is 8 mm (0.3'') closer to suspension/brakes components." ?!
