How to Put Tires on Rims – I’m sick of reading on forums or listening to “coffee conversations” guys who want to change rims or tires and have no clue what is needed, they just want to put the measures that the neighbor uses because it’s cute, then they come crying that the police are bad or that Brands are inflexible in type-approvals and still say to a mouthful that the larger tires are safer when that is not true.

In the ground connection there are sensors that rely on rotations and give information to engine control unit and other systems to indicate our speed, the mileage traveled and still give information to the safety systems such as ABS or ESP. This rotation is “multiplied” according to the Radius of the rim set and tire, if this set is not within the tolerance of the manufacturer we can have safety problems, and I speak from experience because I did the test on my car and the ABS stopped performing properly.

First, we have to understand how the tire measurements work since the values are not necessarily fixed. Let’s assume, a tire 205/50 R15 will have width 205mm, already height (the tire wall) will have 102.5 mm and not 50mm. The 50 value is a division of the first measure. R15 indicates that the tire is radial and its internal diameter (which is adjacent to the rim) is 15 inches. The diameter of this tire is 586mm, which corresponds to 543 rotations per kilometer, so a car fitted with these tires of origin knows that each 543 rotations traveled a kilometer. If we pass to a fashion measure as the 225/45 R17 we have a diameter of 634.3 mm which corresponds to 502 rotations per kilometer, thereby giving an 8.2% error!

This is where a lot of people later say that cars are walking less or consuming more, the kilometers cease to be counted correctly, and in case of emergency it is very probable that the safety systems fail to work, and a car manufacturer will never authorize U A modification of this kind.

Larger is not synonymous with better, just see who puts big discs ahead and then in an emergency braking has the rear to gain life and the car turns, on the contrary, there is a decompensation relative to the values for which it was designed.

So how do you ask… Well, use an online simulator where you can put the original measurement and as you wish to see if the diameter is within the parameters permitted by the manufacturer, you can also consult the manufacturer directly to know which measures are permitted for the car chassis and if Extra modifications are required to change the tires. Do not expect it is miracles with exaggerated measures even if they are within the tolerances of the brand.
