As Grant has pointed out for rims, you can only wear them down to a certain limit, so the worst case is a rim that has the absolute minimum sidewall thickness and will be worn out the first time you brake. Adding a little extra sidewall thickness will greatly increase the lifespan, while adding not very much weight.
With tires, it's the same. The Compass Loup Loup Pass is 3 mm thick (casing + tread combined). You can wear it down to about 1.2 mm before you start increasing the flat risk greatly. (If you are lucky, you may be able to wear the tire down to the casing without flats, but that isn't recommended, because at that point, you are only a few miles away from a blowout.) 3.0 - 1.2 gives you 1.8 mm tread to wear off. The Pari-Moto is 1.8 mm thick mm, so you get only 0.6 mm wear before it's getting very thin. So the Loup Loup Pass should last three times as long, while being only a little heavier. (The Extralight version actually is lighter, but the weight savings come from the casing, not a thinner tread.)
