Tire models , even from the same Manufacturer, can have different tread patterns, compounds sidewall structures and more and for a high performance machine like your Porsche this is not the best area to save a few bucks, imho.

Yeah, I never mix tires on any vehicle.

However, I can remember back in the day (prehistoric times) when no one thought twice about mixing tires. My Dad was infamous for that. One recap, one new, one used and one unknown - that sounds about right. Of course, it was a 1954 Nash Rambler so Fred Flintstone logs would have probably been fine for that fine thoroughbred of a car.

Also, for those wanting some solid 200 Treadwear Rated tires good for track or possibly autocross , there are the typical " Labor Day Savings Programs ," for Bridgestone, Goodyear, Michelin, etc.

Easy to check the ones that are on " Sale " at TireRack or Discount tires.

I dropped my Panamera at the Stealer for some warranty work and they gave me a 2024 Cayenne Base with 300 miles on it as a loaner. It had Hankooks on it. I wonder if they removed the Pirellis to reinstall them when they sell it after its duty as a loaner? Or is Porsche going with Hankooks?
Anyway, I buy Michelin PS for my cars and Continentals for my Cayenne.

Re the Hankooks on a new Cayenne - that is interesting. I wouldn't have thought so but maybe they're being used on base models as you suggested. However, your first supposition might be closer to the truth...

I'm all Michelin on our vehicles. If not Michelin, then Continentals that I like equally well.

For my CPO, the dealership put on ADVAN Sport V105 all around. Never ran these before, great in the dry and impressed in the wet. Less than 2000 mi so far and happy with them.

Surprisingly there seems to be a wide range of tires used on the Cayennes, Macans, and even Caysters. My CPO Macan S had its Goodyears replaced with new Goodyears, so plenty of different brands are being used on Porsche vehicles.
Pirellis, Michelins, Dunlops , etc. can come on a Cayman/Boxster. Once you get to the top line models it does seem Michelin is the #1 usage. I did get PS4Ss on my Cayman GTS and I considered that a bonus.

Just be careful with the V105 when the temp drops. My Cayman came with Yoke's from the factory. The original owner drove it one time on dry roads but with the outside temp in the mid-20's (F). Ruined all 4 tires, they all developed tread cracks clear to the cords. No warranty, Yokohama called it abuse. Not supposed to drive on them below 40°F.

A niche but persistent 'prehistoric' tire-mixing practice among Harley-Davidson owners is to mount automobile tires on their rear wheels. The rationale is that they are cheap and they fit, so they are fine. These folks' salvation, I think, is in their riding styles, which seldom call for much from the tires other than supporting a bike/rider weight often exceeding 1000 pounds. I rode such a bike once, and was dumbfounded that any rider would tolerate such terrible handling. It was dreadful and obviously dangerous. No wonder their group rides are slow parades. Far from our N-spec arguments, this practice is putting tires designed for a near-flat camber on a machine whose very functioning depends on leaning the tire and riding on its shoulder. I'd sooner try to fit a motorcycle tire to a car than a car tire to a bike.

Thanks for the info. I had similar UHP summer tires on my Audis and needed to head the same warnings, they became frozen meatballs with zero traction. I live at 8000 ft so the car will go away into storage at the end of Oct as it is too cold and it starts to snow this month.

these showed up yesterday. PS4s
