Ok. For clarification, I must make sure the front to back size difference ratio is within 3%. Another post mentioned 3% from stock tires size which I’d be in trouble then.

Regarding the 285/35, it seems others are running this and I didn’t see mention of a spacer. I don’t have a problem with a 285/30 but was shooting for a bit more cushion for the occasional pothole.

Others please chime in to guide me before I purchase the tires. Thanks.

Though I think a 285/35 will not fit up front, without a spacer. 285/30 = yes. Also 305/30/20 is what you want on the rear.
