We'll have to agree to differ on that one I'm afraid, there are several different viewpoints out there. Do I have to tell the insurers because my windscreen is now non-OEM? Or what about fitting non-OEM brake pads or discs? Or suspension components? If you have a 'Dynamic' but fit 'Prestigio' wheels then are you still breaking the rules because your car is now modified?
My personal opinion is that my 'modified' wheels are waaaaaaay more legal than the pimped-up bling rings fitted with what look like rubber bands that can be found on various Saxos, 106s, Corsas etc - all of which have been declared to their insurance companies of course
Anyway, back on topic - I've currently gone back to the standard Fiat 18" wheels as KeithGlos was selling his, but I'm still not sure whether I'll stay with the 18s or go back to the 17s. The 17s were more tolerant of road surfaces but the 18s are more stable. No rush to change either way at the minute as the tyres on the 18s have a decent amount of tread and there's plenty of room in my shed.
Out of interest, the 17s were fitted with 225/50 tyres rather that the 215/50s fitted to Cromas, according to the tyre size calculator
here this size is much closer to the 225/45 x 18 rolling circumference. I wouldn't go any bigger than 225/45 as the price gets silly. 225/45 x 18 and 225/50 x 17 are roughly equivalent, with the 17s being slightly cheaper.
The other point to bear in mind is that the 1.9 150 JTD was specified with both 91W and 95Y tyres. Load rating 91 is 615Kg, 95 is 690Kg. The
maximum front axle weight of my 2.4 is 1200Kg so a load rating of 91 is acceptable IMO as I cannot possibly foresee any way in which I will personally get to the maximum front axle weight for the car.
Obvously Fiat (being liable) would rather build in a greater margin of safety but there's only 110Kg difference in kerb weight between the 1.9 auto and 2.4. I've had this before on my old Sharan - VW specify XL tyres but this is to cater for the car carrying seven large adults with a full complement of luggage while towing an 1800Kg trailer. Us consumers are not to be trusted as we do stupid things then blame the manufacturer...
My Alfa wheels look like
this with a Fiat badge in the middle, so they are Fiat wheels if anyone looks (after an accident, for example)
. Have a look at the attachment to see what they look like when fitted - they're on a par with the OEM 18" for looks in my opinion, but easier to clean. I'm sure all the insurance loss adjusters out there will be fully conversant with all the wheels fitted to that high-volume seller, the Fiat Croma.
Speaking of which, you can get some unusual non-standard fit OEM alloys
here. Think I prefer the standard ones though as they're easier to clean and look better (subjective, I know).
Anyway, back on topic, apologies to John for hijacking your thread. Have you found out if your wheel is recoverable?
