That's the ratio of the tire's height to it's width - at 50 (%) , they're equal.
Depending on which trim level it is: 205/60-16 Or 225/50-17 the rims and tires removed from the Mazda rx8 are 225/50-17
It can go 12 times.
The front and rear tire sizes for the NSX changed three times during its run from 1991-2005: 1991-1993 F 205/50/15 R 225/50/16 1994-2001 F 215/45/16 R 245/40/17 2002-2005 F 215/40/17 R 255/40/17
Listed on the driver's door post. It is 225/50-17
As a fraction the answer is 38.25 / 225 38.25 / 225 = 0.17 As a percentage the answer is (.17)*100 = 17%
225
You can install 235/50-17 or 215/60-17 and that is about the only sizes you should use.
The least common multiple of 225 , 50 = 450
Yes, you can use a 225-45-18 tires instead of 225-50-18 tires.
Of course you can but, your speedometer will read 58.9 at a true 60 mph. You will also have slightly less power. My advice is to stick with the OEM size tire.
The tire size 225/50 R17 indicates that the tire has a width of 225 millimeters and an aspect ratio of 50, meaning the sidewall height is 50% of the width. To calculate the sidewall height, multiply 225 mm by 0.50, which equals 112.5 mm. The overall diameter of the tire can be found by adding twice the sidewall height to the diameter of the wheel: 17 inches (converted to mm) is approximately 431.8 mm, so the overall height is about 656.8 mm or roughly 25.9 inches.
You have not given the whole tire ID number. -It's essential.For instance, you could replace a 235/65 R 15 with a 225/65 R 15.- You could NOT replace a 235/70 R 15 with a 225/50 R 15.That second set of digits, the profile #, IS important and you should not expect a good answer without giving ALL the pertinent facts
