We had been considering switching tires as our 145/80 tires looked somewhat small. The Seven Series 2 was delivered with 520 x 13 tires, with a width of 14 cm and a diameter of approximately 58 cm. Our 145/80’s were not too far off regarding width but had a diameter of only approximately 56 cm, even with their relatively high 80 profile. Our narrow wings leave very little space for larger tires but we decided to give a set of 155’s a go. We had been quite happy with our Uniroyal RainExpert tires but stumbled on a set of Retro Classics that have a very contemporary look. The diameter of the 155/80’s is approximately 58 cm and they fit nicely within the narrow wings.
