205-40r17 will they fit my car?

Will 205-40r17 size tires 17" rims fit my 2000 Honda Accord

A 225-40-19 will fit your 05 Accord so a 205-50-17 will definitely fit.BTW-a 205-50-17 is
8.07" wide
4.04" tall-sidewall height
These two measurements will allow you to visualize what the tires will look like once they're mounted or you can go a step further by actually holding a tape measure on top of the existing tire to see how much wider(if any)the new tire is gonna be. Then you can hold the tape measure up to the top edge of the rim and measure upwards 4.04" inches to see how much taller or shorter the new tire will be that way you'll know how much of a gap will exist between the top of the tire and the fender.Installing bigger diameter rims and low profile tires is a good way to reduce fender gap and make the car look as if its been lowered rather than drastically lowering the car with stiff springs that ride like hell.You'll probably have to reprogram the computer so the speedometer will read correctly, depending on how much of a difference there's between the new tires
