That's the size used on the 126. It's a bit taller with lower revs per mile. I installed 205/60s on my 201 using 124 wheels which a half-inch wider with the same offset, and the 205/60s are the same revs/mile as the OE 185/65s so speedometer calibration was not effected.

I did have a slight amount of interference at the front of the front fender where it meets the bumper, so I dressed it with a file and finished with some primer and touchup paint. No one could ever tell.

205/60s on OE wheels should be okay, but will cause your speedo to read a bit high because they are fewer revs per mile than the 195/65s that were OE on 124s. 215/60s will be about the right revs/mile, but you might run into some slight interference problems like I did.

Tire sales Web sites and tire manufacturer sites have detailed tire dimension, revs/mile, and load data. Using the difference between 195/65 and 215/60 you can make some measurements, and make sure you check the fronts at full left and right lock.
