Wheel Width/Tyre Width

I put on a set of 205/55 on 6J rims recently. A non-turbo 900 that is, it looks great and I can imagine that they wouldn't on 5,5J rims. The tyres are chinese Maxxis tyres (used ones I got for cheap).

I know one guy who's running 195/65 on a CV... it seems to work, but doesn't look any good! Here in germany it's for bidden anyway.

I think I can take some pics of both if you like (drop me a mail in that case). /T.

I'd love to see a picture, especially of the rims. I know different manufacturers look very different, but it would give me an idea.

There was some discussion here recently about the legality of wheels and tyres in Germany. Is it the 195/65 ratio that is illegal on the classic 900?

Our convertible is not lowered, so it could take a little higher percentage tyre wall size, but I'd like to go with a ratio equivalent to the standard or perhaps the standard ratio if the 205/55 look a bit "fat".

On my C900 Aero, the suspension is quite lowered, but stiff and I can get away with the 195/65 ratio that is on my 7" width wheels, so I think 205/60 would be okay too. The wheels are quite small-looking, being a split rim, so it looks kind of retro to have big tyres on them ... Hopefully the 205 width will give them an even fatter look.

It's these wheels, in case you were wondering:

I'd like to see the 205/55s on the 6" width wheels. I've e-mailed you as a sideline.

My 83 turbo came with 6.5" wide 3-spoke aftermarker 'Speedy' wheels which had Yokohama 205/65 tyres. They rubbed on the wheel arches even without anyone in the back when I put them on the 85 900i for a while before I sold the wheels on Ebay and went back to some standard Saab 5.5" wheels on that car. I think they may have been better with 205/55 or even 205/45 tyres (though 205/45 might have made the car too low by a smidgen).

Illegal how though? Because it puts the speedo ratio out? Something to do with the effect that particular tyre size has on the car's geometry when driving?

We already went through that subject a couple weeks ago :-)

Apparently Germany has strict regulations on tire sizes being in conformance with original manufacturer specs.

(They also regulate bicycle lights closely!).

I sent you some pics of my 205/55 on 6Jx15 ET33 Fundo "Turbo 9000" rims. Usually I drive on Minilites, but since some people told not to go for the 205/55s, I bought a cheap test-setup ;)

see here:

Yes, It's not only illegal, it looks strange ;) I can try to take some pics of my colleagues CV tomorrow at work.

You should go with the standard diameter... everything else looks strange. As you can see on the pics they don't look "fat", only wide.

You have to have a littel distance ring for the rear springs...

Thanks for the pictures - TBH, I'm inclined to go with 205/55s on my 6" wheels (SAAB wheels, so ET33) which are certainly within the parameters for fitting into the arches on the convertible.

They look fine on the wheel and seem to sit nicely in the arches. I definitely _would not_ go for 205/55s on the 5.5" wheels and definitely _would_ on the 7" width wheels, so the issue was ... What to go for on the

Thanks again,

Paul

'welcome. I'm happy with that setup as well. /T.
