Summer Range tires vs All Season tires.

[babylou66]

Cayenne EV, in 21" diameter, has two tire choices; summer range and all season. Anyone know any real difference like treadwear ratings or range effect? We all know all season are superior in moderately lower temperatures and summer tires have more grip in the dry.

There are so many tire construction variables. Hard to compare tire X with Y under a blanket generalization (such as summer tires, etc). What I do instead it to go to a comparative site such as TireRack, put in sizing I want then look at UTQG ratings for each of the tires that interests me.

Of course with Porsche being a bearcat when they want on warranty approvals or not if the problem with the the car might be remotely related to the tires on the car when it was turned in the dealership, with Porsche more restrictive than any other brand I have ever owned, I look for all NFO or other Porsche approved tires too as part of my tire choice decision making.

BTW, BMW is similarly very strict with EV tire approval. I know when a friend turned in his lease BMW that had lots of tire treat left on all four evenly-worn tires, but the tires he had on his vehicle at the time of the end of lease “turn in inspection,” were not ones offered on his EV when he first leased it, i.e., they told him that he needed to replace all four with tires originally lease delivered. So if your Porsche is leased, or if you experience a vehicle problem that occurs during warranty, IMO we need to be extra careful of the any deviation tires we put on our Porsches.
