Because if you didn't and ran 255-40 on the rear and 225-40 on the front, the rear tires would be 12mm (1/2") taller. With the other set-up (255-40 & 225-45) the sidewalls are much closer to the same height.

So, the deal is that Tire Manufactures make tires of a lot of different sizes but not ALL different sizes. That makes the car manufactures that use these tires, to come up with the optimal combination for their cars. A difference of less than a percent between the overall diameter of the tires front to rear is within the tolerance of the design of the suspension etc. That 1 percent difference is close to very normal due to difference in inflation pressures.

Long story short, they try to come up with the best combination and we should follow them because they are the ones testing these for us before selling us the cars.

Hope this helps.

No offense to some members on the group but there are dudes making less than $35K driving in fairly new cars - lol like leasing a $40k car - wtf - the car is worth more than what you make in a year!

OP just be sensible - good luck!
