I'm new to the forum currently have a 15 MDX Silver SH-AWD, its almost time to change tires so may as well change the rims. Is it me or does it seem like these wheel/tire calculators seem a little off. I'm inserting the specs for current/new wheel/tire combo and 2 of the calculators are close but the third is off. Just wondering to make sure I'm not crazy. For those that installed aftermarket wheels, could you share some feedback about ride comfort ?

I'm torn between 19x9.5 +39 and 20x10 +40, my plan is to eventually install BC Coilovers...

Current
245/55R19
19x8 +55

New
255/55R19 Michelin Premier LTX
19x9.5 +39 TSX Bathurst Rotary Forged Silver
