Which tires can I use? Techart / OZ fittipaldi 9J + 10J x 17

  • Hello everyone,

    I currently have several "problems" with my rims. On the one hand, the size of the tires currently fitted is no longer available, and on the other hand, they are a bit too "bulky" for me anyway, as I would actually like to go a good bit lower.

    Are there any manufacturers that have an approval for 225 on the 9J rim and 255 for the 10J?

    This combination is currently fitted:

    235/45 VA

    265/40 HA

    Thank you and best regards,

    Michael

  • Every year again the topic of "tire approvals and brand loyalty"... k:swoon:

    Some motorcycle and car manufacturers specify a tire brand in the vehicle registration certificate, whereby not only certain tire sizes, but also only certain tire brands and designs were registered and thus approved. In most cases, these were vehicles with a top speed of more than 230 km/h. This measure was always justified with the argument of safety based on extensive and comparative tire tests with the vehicle concerned.

    According to German legislation, these restrictions only applied to summer tires. Winter tires of the same size (M&S) from other tire manufacturers were allowed to be fitted on vehicles affected by the brand restriction. In a letter dated February 4, 2000 and with effect from March 1, 2000, the European Commission declared the existing tire brand restriction to be inadmissible.

    The provisions of Articles 4, 5 and 6 of EC Directive 92/23, which was transposed into national law in August 1997, do not allow for such a restriction.

    Accordingly, it would be inadmissible to have a manufacturing restriction and no transitional periods apply. This means that, with immediate effect, it is no longer permitted to enter any tire brand bindings in the vehicle documents of new vehicles. The entries that still exist at present no longer have any direct legal effect and are to be regarded as recommendations. At the same time, this abolition of tire brand binding also means that the vehicle owner is now also responsible for ensuring that no safety problems arise when using tires that do not correspond to the registered version, just as he is generally responsible for the roadworthy and operationally safe condition of the vehicle anyway.

    In short: fit what is required and available and be happy.

    Just noticed - 265/40 on 17" will indeed be difficult, but 255 should work, probably just have to go up a bit 45 or 50 in width...

    Apart from that - your yellow 964 Cabrio :augenreib: Coupé looks rattling hot! k:good: I didn't look closely and thought it was a convertible... *8)

  • Hello,

    Schulisco, it's not about the manufacturer.

    I'm interested in what I can ride on the rims and also what the rolling circumference is right and the front and rear sizes match.

    Of course, the tires also need to be approved for the rim width so that I can get them registered.

  • Moin,

    The RUF Speedline in 17 have similar sizes for different vehicles.

    I can look them up tonight...or google them...

    What for? All-wheel drive??? On a 964 turbo?

    The tires also need to be approved for the rim width so that I can get them registered.

    The easiest way would be to call 07152/9339-0 and ask Techart directly...

    I only know the RUF in 8 + 9J but if there are others I'd be happy to

  • Okay, RUF recommends 235/45 VA and 255/40 HA

    I'll have to talk to my wheel specialist and see what he says.

    I now also have 235/45 on the VA and they are really too wide
