Hey guys, I was wondering if anyone here uses these ?? Would they give me a softer ride 'cuz they have a thicker sidewall ?

I have yet to use them, but am contemplating a purchase in that size. The concern is whether a specific 225/50 would rub the inside of the (unrolled) rear fender; Mazda does not leave a whole lot of clearance between the fender and the tire.
There is no reason to believe that the sidewall would be any thicker for a 225/50 than a 215/50of the same brand and model. There is also no predicting, without actually mounting the tire and riding on it, whether a 225/50 of one brand and model would ride any more softly or more harshly than a 215/50 of another brand and model.
The overall diameter of a 225/50, mounted on the stock 17" wheel with 7" rim, should be slightly greater than the overall diameter of the stock Michelin Pilot HX MXM4 215/50. The stock tires when new, mounted on 7" masuring rims, and properly inflated, rotate 819 revolutions per mile; the specifications for most 225/50 tires, when mounted on 7" measuring rims, state that they will rotate between 805 and 810 revolutions per mile. That would mean that the gearing would be slightly higher (that is, lower ratios) and the speedometer and odometer would be slightly slow. Assuming a 225/50 tire with 805 rpm, when the Mazda6 speedometer reads55 mph, you would actually be traveling 56 mph (819/805 x 55). If you refill your gas tank when the odometer says 300.0 miles, you would actually have traveled 305.2 miles, and your actual miles per gallon on that tank, if you filled it the previous time and filled it this time with 15.000 gallons, would not be 20.00 mpg, but instead 20.35 mpg.
