Help: Any kind of paperwork for larger tires!
Hi guys,
you've shown how much is technically possible with a Pinin. What is *legally* possible in an over-regulated jurisdiction is a different story though ;-)
Please let me know of any aftermarket or even OEM homologations for ANY kind of taller tires that you know of.
To gain offcial approval for tires with a (significantly) bigger diameter than stock, I need what they call 'comparative certificates', which basically means documents for a homologation of a larger tire size that somebody else has already had done. (Having a homologation done myself is cost prohibitive.)
After a fair bit of web research, it looks as though even back in the day, no aftermarket supplier has had kits for significantly taller-than-stock wheels homologated for the German market. All I found was sizes like 225/60-16, 235-60-16, 255/50-17, 245/45-18 etc which are only fractionally taller, or even smaller, than the stock dimension of 215/65-16.
I'm determined to leave no stone unturned though.
Please let me know of any aftermarket or even OEM homologations for larger tires that you know of.
Preferably from European or even EU jurisdictions, but there is a slim chance that even approval documents of any kind from other markets may be useful in convincing the 'authorities' they are not taking undue risks by letting me drive around that way ;-)

Success!
I got a release from Matador for that size.
MP71 Izzarda not the tire I dream about in sleepless nights buit it's a start.
235 and 245 tire sizes appear to be needing wider rims, 7-8.5 inches.
Yes, It is illegal to fit 245 tyres on a 6 inches rim in Australia, at least in my state (ACT)
I was told that bigger tyres could be approved if the speedo is correct and if the braking power is to a safe level.....all checked and tested by approved engineer.
Happy io
It may depend on the tire manufacturer & profile
235 and 245 tire sizes appear to be needing wider rims, 7-8.5 inches.
I have the Dunlop books, and the allowable rim widths vary with the tire profile, not just the width - for example a GrandTrek AT3 ...
235/70R16 - 6J~8J
235/60R16 - 6.5J~8.5J
235/85R16 - 6J~7.5J
245/70R16 - 6.5J~8J
Thanks to all who responded
Thanks to all who responded and will respond in this thread.
Out of curiosity, and to all who read this around the world: What is the stance of your jurisdiction toward fitting tires in different dimensions from OEM? Do the authorities pretty much let you use whatever tire size you want?
australia.
It varies from state to state, in Qld where I live it is 25mm lift maximum with tyres from biggest oem size. Width is fairly however you can only widen the track by 25mm and tyres must be within guards.
I run 225 75 16 which is about 28mm over the 215 65 16 on my plackard however I've also lifted about 100mm so it looks in proportion and ive never had trouble. (Leagal is 50mm lift max)
Nsw and vic can have 50mm lift total so that could be 50mm on tyres or body or a mix.

Some restrictions

As far as I know we are not restricted on tyres per se but there are restrictions on how it presents and insurance companies need to be informed and MoT (vehicle tests) has to be passed (it has to be roadworthy). Lots of wide wheels and big tyres get fitted every day. We worry more about clearances under the arch.

215/70R16
It's not that much larger, but the Japanese domestic market used 215/70R16 as the OE size - roughly 25mm larger - I have no paperwork, but I can take a picture of the "tire placard" on the door jamb if that will help any.
