Do 2025 Cayennes come with bigger wheels than 2020 ?
Do 2025 Cayennes come with bigger wheels than 2020 ?
My father in law just got his 2025 Cayenne on 21". I have noticed how meaty the rubber is on OE 21" rims. Then I checked the tires and they are 285/45/21" front and 315/40/21" rear.
My 2020 car's manual calls for 285/40/21" front and 315/35/21" rear tires, which would mean the new Cayenne has the wheels (not rims!) 1" bigger. The wheel diamater goes from 761.4mm to 789.9mm, which is a bit over an inch.
I wonder if anyone put the bigger wheels on pre-facelift Cayenne E3?
The speedo error is -3.61%. I don't care about the slight loss of acceleration or the speedometer error - the wheels just look much nicer filling the wheel gap better. I was thinking about getting a lowering springs to get rid of the wheel gap (sadly, my car has no air suspension), but that would result in much harsher ride. Suddenly, 1" bigger wheels sound like an all around better solution.
Yes the tires on 2024 models and up have taller sidewall than the equivalent wheel option on pre-refresh models. Kinda its like 22” now has the same sidewall of 21” wheels from pre refresh.
i have 21 inch wheels on a 2024 coupe and the taller sidewalls make it much harder to curb the wheels. this is a pretty big plus in an urban environment w all the parallel parking and tight driveways it is easy to clip the curb because the cayenne is big and wide.
2024+ went to 31.0” overall height, regardless of the wheel size. Earlier cars are 30.0” overall height.
Great comparison between your 2020 and your FIL’s 2025: same wheel size, same tire widths, but higher aspect ratio for 2025 results in taller sidewall vs. 2020.
I’ve run 31.0” on my 2021 with no rubbing and no driveability issues (avatar photo). I simply went up from 55 to 60 aspect ration on the 255-19 tires. I’ll be changing to the larger diameter for street tires when the OE set wears out.
For wheel gap, also consider spacers to bring the edge of the tire a bit closer to the fender. I have 5mm / 12mm spacers on my Boxster because I did not want to lower it - works great, even on the track.
The tire size change occurred from the 2024 model year. This is due to switching in Cayenne from a 3-chamber air suspension to a 2-chamber one. The pre-2024 models should not use the tire size from the facelift models.

I value your perspective from previous posts - why would an air suspension change support larger tires? The air bags are the same physical size, shocks are the same, all suspension components are the same, wheels / hubs / brakes all the same.
I’m curious about your logic when the entire chassis has remained the same from 2019 to current.

air suspension design change has nothing to do with tire size. With or without air suspension tire size is the same on 2024+ MY Cayennes
Call me a cynic. We could science the size change to death but I’ll bet everything is a secondary benefit to the reportable and infintessimal fuel mileage increase they get and report. The greater sidewall is a benefit around curbs of course.

No, the new suspension is not the same as in 2019. However to explain it more precisely, this question is more for Porsche engineers than for me. IMO, the 2-chamber, 2-valve suspension is stiffer but also more responsive.This technology allows also for a greater range of suspension stiffness adjustment depending on the driving mode. Seems that in order to compensate of the greater stiffness of the suspension and still maintain a high level of comfort, the tire size was changed. 2-chamber, 2-valve airbags may be the same size but they react faster than 3-chamber airbags with 1-valve technology. And this speed of reaction was the goal of Porsche designers.
I think that the standard suspension was also tuned differently with new shock absorbers also in 2-valve technology so that the car was more responsive with better handling while maintaining high comfort. In other words, better car handling was achieved but not at the expense of further lowering of the tire height but thanks to better suspension. And so much so that it allowed changing the tire size on higher and "safer" from the point of view of everyday use of the car. They killed 2 birds with one stone.
The change in tire size was definitely not dictated by anyone's whim but had its rational justification as a suspension/tire combination.

Assuming there were no gearing changes 2024+, taller tires (31.0") would result in a bit slower acceleration but lower RPMs at cruising speed. Hence better gas mileage.
Since my Base has only 340-ish hp, I'll take the larger sidewall for comfort and better filling the wheelwell with the 31s vs. OE 30.0'.

but the 2024 cars aren’t slower than pre 2024 cars, are they? i am asking i really don’t know. i know they have have more horsepower/torque, though just a small amount.
