Hey guys, I have a 2014 q60 AWD, and I wanna replace the rimes and tires, but someone said the AWD car only can use the same spec rim&tire for all wheels, so could someone tell me that can I use 20/10.5J rims and 255/35/20 tires on front wheels, and 20/10.5J rims and 285/30/20 tires on rear wheels, or I should use 20/9J rims and 255/35/20 tires for 4 wheels. Thank you so much.

 

You are not limited to a "square" set-up, but you have to careful that the difference between the front and rear tire diameters is no more than 1%. Exceeding this limit could damage the transfer case.

 

Thank you so much!!!! That's help me a lot!
