I put 165-15 tires on stock wheels on my 101.18 Spider in the early 1970's and had occasional rubbing on the front end. The car was about 9 years old, which I thought made it an old car, and I weighed 175 lbs (80 kg) back then. The 165's are taller and wider than the spec 155's. You should check that the back spacing on the new wheels is the same as the original wheels. That being said, yes the springs may have settled. An unscientific observation indicates that Spiders frequently have only the driver aboard and the driver's side may have settled more than the passenger side. At one point I put stiffer lowering springs on the car and did not like the look or the ride, but I am a grumpy old man and you may have different opinions.
