Hi, since G35X is AWD system, I was wondering if the differential will screw up by using 215/55R17 at the front tires and 225/55R17 at the rear tires?

The tire's thickness of 215/55R17 is 118.25 mm, and 123.75 mm for 225/55R17, there are 4.4% different between the two thickness.

The overall tire diameter will be 1.6% different between the two tires size.

Many thanks.

 

You cannot run staggered diameter tires with AWD. Width is mostly unimportant but the diameter MUST be the same.

EDIT: Well technically you CAN but you need to disable the transfer case by pulling the fuse and thus it wouldn't exactly be AWD anymore...

 

Thank you for your answer.

So will the AWD system get damage immediately by the tires setting? I already mounted the small size tires on the front, can I still drive it for just couple days that I commute for the work? (I already ordered the new tires for the rear which are the same size as the front tire, but I will receive it until next week.) Thanks.

 

It will immediately start to sense a difference in wheel rotation and engage the transfer case, it would probably take a few weeks to overheat and destroy itself but you can eliminate that risk by disabling it's power.

 

Gotcha! Thank you so much!
