I currently have some CCW505a 19x10 front and 19x11 rear and current tire size are 275/30/19 front and 305/30/19 rear. The rear seem to be too wide and I've had problems with rubbing so now that it's time for new tires, I was wondering if 285/35/19 will work on the rear rims or are they too narrow? I plugged it into one of those online calculators and it says the difference is -6.6% , -0.79"


Current Tire New Tire Difference
Diameter inches (mm) 26.2 (665.6) 26.85 (682.1) 0.65 (16.5) 2.5%
Width inches (mm) 12.01 (305) 11.22 (285) -0.79 (-20) -6.6%
Circum. inches (mm) 82.32 (2091.04) 84.37 (2142.88) 2.04 (51.84) 2.5%
Sidewall Height inches (mm) 3.6 (91.5) 3.93 (99.75) 0.32 (8.25) 9%
Revolutions per mile (km) 769.64 (478.23) 751.02 (466.66) -18.62 (-11.57) -2.4%

Thanks in advance for your assistance.
