Are Michelin Pilot tires taller than Nexen N7000?
As a generalization, a tire that is 275/35/20 is that size – that specifies how wide and how tall a tire is, and what size wheel it is for. So, speaking in generalizations, this is like asking if a 3 foot tall red box is taller than a 3 foot tall black box. But there is always the details, and different manufacturers will wind up having slight differences (a tenth of an inch difference isn’t uncommon)… but in this case, both Michelin and Nexan list the tires you mention (assuming you mean PS2 by “Pilot Sport”) as being 27.55″ diameter.
