rang my insurance company up www.shannons.com.au and asked if i would still be covered by insurance if i went to a car tyre... they replied as long as its OK with the RTA ...Roads and traffic... then its ok with them... so i rang up the RTA they said as long as it as size of tyre thats recomended on Plate on bike its is ok....and as long as its not
15 mm larger size or 15mm smaller size... the person i spoke to in the technical section said i was the first to inquire about a car tyre fitted to a motorcycle ... seems a bit unclear to me still but if any rocket captains are with shannons ring them up..
Wheels As a general rule, it is recommended you only fit wheels and tyres that are listed on the tyre placard or in the owner’s handbook. These have been tested and proved for your car. (seems there is no provision for motorcycles) Sometimes the range of wheels listed by the manufacturer may appear to be limited. While it is recommended that you only fit these wheels, the RTA does not oppose the fitting of wheels outside the range providing they are safe for the vehicle. An important requirement for all replacement wheels is that the wheel track must not be increased by more than 25mm beyond the maximum specified by the vehicle manufacturer for that vehicle. Where non original axle or suspension components are fitted, the offset of the wheel in relation to the axle or stub axle assembly used shall not be increased by more than 12.5mm each side of the vehicle based on the specifications of the axle components used. If an axle assembly is shortened then the track width limit is taken as the axle manufacturers original track dimension, less the amount the assembly has been narrowed, plus 25mm. If you are contemplating fitting non original axle or suspension components you should seek the guidance of a signatory as engineering certification will be required (see page 3). Minor changes to wheels Wheels up to 26mm wider than the largest optional wheel recommended by the vehicle manufacturer for the vehicle can be fitted without the need to notify the RTA. The outside diameter of the wheel and tyre combination must be no more than 15mm over the largest diameter wheel and tyre combination specified for the vehicle and not more than 15mm below the smallest diameter wheel and tyre combination specified for the vehicle.

Rob, i am with Shannons too and to me its seems like a 225 car tyre would be ok. But then again 225 + 15 = 240, dum technicality hey but theres that 15 mil difference they talk about, are we talking measuring with a tape or whats on the tyre?

The guy at the RTA said as long as its not over 15mm or under 15 mm he said and he said as long as its listed in the tyre sizes thats on the bikes compliance plate ... is there a plate with tyre sizes? there is in the manual...hmm in manual it says WARNING Use the recomended tyres ONLY in configuration given.. Do not mix tyres from differnt manufactures.... and so on.....

why not be honest with shannons....feed all the info to them and let them make a call...better now then in the future when they are looking over the bike after an accident....

Sounds pretty clear to me... 225 is Ok. And it is Ok with the RTA so it is coverede by the insurer!
