    Depends on the engine. The 1.9s had 165r13s. The 1.1s had 155r13.

    I recall from my days as a make-ready mechanic in a Buick dealership that no one manufacturer was standard. We had customers that either had a preference for one brand or another, or a bias against the brand that was on the car, and requested the tires be changed. That would send us out into the lot looking for a car with the sought-after tires and we would switch the tires (occasionally forgetting to swap the spare). This of course is illegal in today's world. This happened more often with the Buicks, but we would occasionally see it with an Opel.

    are you guys fitting Michelin XAS

    or do you fit 175/70R13 or 185/70R13?

    is anyone fitting Pirelli Cinturato? https://www.lucasclassictires.com/18...857013CN36.htm

    I think the Kadett came with bias-ply tires. Likely 165-13. The 185/70-13 would be your best bet as they fit the rims you have. The XAS looks pricey so would you really be able to push them to justify getting them over a lower performing option? Some have gotten the CN36 https://www.opelgt.com/forums/genera...n36-tires.html tires, but again they come at a price. As a friend and I discussed this weekend, you can't drive like we used to which was often at 8-9/10ths. Tires made a big difference. Today I look for quiet and low rolling resistance.

    The Kadett came with a Uniroyal in an odd ball metric size, that doesn’t come up even with Coker tire and reproduction tire mold companies. I have saved as many spares as I can. Didn’t matter 1.1 or 1.9, but Rallye model would have received a larger steel belted radial. There were a couple of variances. They were a 6,15-13/155-13. So today’s standard is the 155/80r13, and a GT was a 6,45-13/165-13 in a Dunlop. One of the Uniroyal tires states Uniroyal Englebert and the other just Uniroyal. All state 4 ply Rayon. I’m not 100% on the GT tire being a factory tire or not.

    My 1970 GT has an original spare that is a uniroyal 165R13. Never been on the car.

    This would mean you would want a 175/70-13 to keep the speedo correct.

    a 175/70R 13 is a low profile version of a 155R13

    a 185/70R13 is a low profile version of a 165R13

    there is a plan next year for Pirelli to make some period 155R13 and 165R13 tyres.

    in the mean time i think the best full profile tyres for for you guys are the Michelin XAS https://www.youtube.com/watch?v=0vD_ja3addM

    You didn’t really state what you have or what you wanted. Yes those tires are a lower profile and a lot wider too. I’ve put 205/60r13 on a Kadett Rallye rim and fit nice.

    Here are a few pictures of the spare tire and wheel from my 1973 GT. It is a Dunlop 165R13 and is still in pretty good shape. It was never a good handling or wearing tire and by the time I had the car for a year or so, I dumped the Dunlops and installed Michelin XAS tires. I loved the XAS tires and still have them mounted on the rims in the attic. Kept the unused Dunlop for a spare only.
    When I was in the Army in Germany, there was a huge Dunlop tire factory in Hanau, near Frankfurt and it would have been very handy to the Opel plant. That may be why you see so many Dunlops on Opels; they were made in Germany and fairly close to the Opel Factory. So to Opel, maybe the Dunlop's were just like Jim Varney's neighbor's wife, hot, fast and cheap! https://www.google.com/search?channe...HcWGsQX67qCYCA

    How wide are Kadett rims. Those tires require a minimum of 5.5” rim width.

    There are two widths according to my Kadett/Olympia owners manual, 4-1/2J 13 and 5J 13. The narrower wheel is probably for the disc braked ohv.

    Same width as a GT rim. That’s exactly what a Rallye wheel is, a 1972 Opel GT wheel without the center cap clips unless you count the 1970 rim. I’ve put 205/60r13s on them all the time

    That’s what I thought. You can mount wide tires on narrow rims but it affects their performance. It can also cause rim failure on some wheel designs.

    The best scenario is to pick a tire where the wheel width is in the center of the tire’s range.

    Here is a chart with allowable tire widths vs wheel widths. First column to the left is wheel width in inches, second column is minimum tire width in mm's, third column is recommended tire widths in mm's, fourth column is maximum tire width in mm's.

    Vincent, the OP asked about tires for a Kadett, which were typically smaller than on a GT. The correct "modern" (well, not quite modern!) tire for a GT would be a 185/70-13. Your 175/70-13 tires are a tad small

    it must be horrible to drive on a 205/60r13

    is it a race car
