i had this exact issue when i put my winter wheels on. I put on 225/45-17 in front and 255/40-17 in the rear. The tires I bought had Identical outer diameters (according to spec), but the difference in width caused a different rolling radius (front tires compressed more). I swapped the rears out for identical 225/45-17 tires and the problem disappeared.

My stock tires (staggered 18s) are 0.1" larger OD in the front than in the back, but because they are narrower, when the tires are loaded, all four have similar rolling radii.

Be very careful when selecting staggered tires, even though the tire spec says that the OD is the same, once it is loaded, it may not be.
