I drive a Chrysler 300 Limited. The stock tires on the car are 215/65/17". I found some used, cheap snow tires but the are 225/50/17". What are the basic guidelines to tell you how much over/under the stock size will fit on the rims?
Thanks

A 50 series tire seems like it would be too wide to function effectively as a snow tire. When possible, you want a tire that is narrower because a narrower tire concentrates more of the vehicle weight on the 'contact patch' of the tire and allows it to dig in and grip the snow. A wider tire would float over the top and be more likely to skid over ice and hard-packed snow.

The 50 indicates that this tire size's sidewall height (from rim to tread) is 50% of its section width. The measurement is the tire's section height, and also referred to as the tire's series, profile or aspect ratio. The higher the number, the taller the sidewall; the lower the number, the lower the sidewall. We know that this tire size's section width is 225mm and that its section height is 50% of 225mm. By converting the 225mm to inches (225 / 25.4 = 8.86") and multiplying it by 50% (.50) we confirm that this tire size results in a tire section height of 4.43". If this tire were a P225/70R16 size, our calculation would confirm that the size would result in a section height of 6.20", approximately a 1.8-inch taller sidewall.

they will fit on your rims but will throw the speedometer off also !

quick answer: if it looks too good to be true, it is.
