Porsche Cayenne larger wheel/tire
I have a 2008 porsche cayene base SUV i just bought 2 months ago. The OEM tires were continental 4x4 contact 235/65/17 on it.I want to upgrade to 20 wheel so I tried to look for an original used wheel. I was able to bought a used wheel size 20 only to find that the 2 wheel was wider. I think it was for a porsche cayene car and not for SUV. I brought the wheel to Discount Tire store to get their advised and and if i can use it. They check the wheel and my car.They put 275 /40 R20 BRIDGESTONE DUELER H/P SPORT infront and 315 /35 R20 110W XL BRIDGESTONE DUELER H/P SPORT on the rear. Can i really use it. It looks good and runs okey but im still worried about it. Please give your advises, im worried it will break my engine, transmission, or suspension. I really not good about car!!Thanks and God Bless You!!!
