size my wheels

Hello.

Do you want to know the size of the rims for your car? My site will help you choose the size of wheels for your car.

For each rim, you need to find a personal version of the rubber that fits it. Making the wrong choice can pay dearly for this folly. It is difficult to miscalculate the diameter, because setting the wrong size is problematic. But there is a chance to be mistaken with the width. If we take too narrow or wide discs, then the design profile of the tire will invariably suffer and its characteristics will deteriorate: quick response on turns and during maneuvers, sidewall rigidity will decrease, and drag resistance will worsen.

The axiom when selecting a rims says: the width of the disc rim must be 25% less than the width of the rubber profile. For the presented size 195/65 R15 91 T, the disc width can be calculated as follows: first calculate the profile width in inches. 195 divided by the figure 25.4 (it means the number in 1 inch mm.) It turns out 7.68 inches. Subtract 25% from this value, and then round the result. The formula looks like this: 195 / 25.4-25% = 5.76. Rounding up, it turns out that a 6-inch disc is needed for a given size.

It is permissible to take discs with a deviation in the rim width of no more than 1 "if it is a disc with a diameter of up to 14". For discs 15 "and above" the maximum deflection is 1.5 ".
