Wheels and Tires

Steering wheel vibration

I have had my local Porsche dealer perform two separate road force balance of all four wheels/tires on my 2018 Cayenne GTS.  I get steering wheel vibration between 70-75 mph.  I suspect the issue could be the Goodyear Eagle tires that are OEM size- 275/45/20.

Alignment has also been performed.   This has been very frustrating, and I think I have exhausted the dealerships efforts.  Still not satisfied with the results.  Any suggestions would be welcome.




What tires would you recommend for 2011 Cayenne that does mostly city driving in Washngton DC area

Front wheel bearing

Model: Cayenne S, Year:2005, Mileage:92,000, Type of use:Street use only
My left front wheel seems to gradually be getting louder. I swapped tires and no change. While tire was off I removed the brake pads and turned the rotor, but could not feel any wobble. The sound doesn't change when using the brakes, and there is no abnormal tire wear. Going straight or turning left the sound is loudest. When turning to the right the sound is less. Am I correct in thinking it is my wheel bearing, and if so is it a DIY project to change the bearing? Thanks, Matt

Cayenne air pump

Model: Cayenne, Year:2006, Mileage:64000, Type of use:Street use only

tire pressure monitors

Model: Cayenne, Year:2008, Mileage:29000, Type of use:Street use only
I currently have a base Cayenne with 17 inch wheels and tires with tire pressure monitors. The tires are starting to wear. Have a chance to purchase a set of 18 inch Cayenne S tires and wheels with o miles (take offs). They have the tire pressure monitors still in them. Will the TPM from the new ones work on my car? Thanks

size vs. performance

Model: GTS, Year:2008, Mileage:20000, Type of use:Street use only
I have a GTS with standard 21" wheels. I want to get an addional set of wheels and tires but i can only find 20's or 22's. I like how the 22" look but the dealer service department advises against changing the size either way. (smaller or bigger). I want to get a set of 22's with similar tire ratio as the OEM tires 285/35 22s. vs. 295/35 21s. The dealer claims that performance and diagnostic protocols will be compromise if i do not keep the same size from original but i really like to get another set.

Staggered tire size?

Model: Cayenne, Year:2004, Mileage:74700, Type of use:Street use only

Towing capacity with 21 inch tires
