Tyres play an important role in the driving characteristics of a car and therefore in the active safety of your Focus: the carcass, the rubber compound and the computer-calculated tyre profile make modern radial tyres high-tech products. On the bearing surface of each wheel, the size of a postcard, they carry your Focus head-on, absorb small road shocks and transfer all driving, braking and centrifugal forces. Under average load, the radial tyres on your Focus last for about 30,000 to 50,000 km on the front axle and about 40,000 to 70,000 km on the "dragging" rear axle. If you mainly drive short distances, you should change your tyres – regardless of their residual profile depth – no later than after 7-8 years. During this period, dirt, chemical influences of the environment, internal ageing processes and, not least, the sun have damaged them so much that they can no longer reliably do their job. However, do not trust the old spare wheel, which looks like new, either; the appearance is a deception, underneath is dangerously aged material.
There are two versions in the factory package - Focus rims
Ford equips all Focus models with two main types of rims: depending on the design and model, sheet steel or light metal rims with dimensions of 5J x or 6J x 15" are used. Light metal rims are always supplied in the dimensions 6J x 15". Our table lists the sizes that Ford provides as a factory or special equipment for the various models. The sizes of tires and rims approved for your Focus are specified in the vehicle registration document. However, if you want to fit your Focus with other wheels, the approved products must have a General Operating Approval (AVE) with the corresponding inspection number. If the tire sizes are not specified in the vehicle registration document, check with Ford or with an authorized person at TUV/DEKRA before installation to find out about their suitability. Rims and tires that are not included in the registration document at the factory must be included in the vehicle documents (letter and certificate) by means of a partial examination at TUV/DEKRA.
Rims
The rim size according to the standard is always given in inches. For example, the designation 5J x 14" means a deep-bed rim with a width of five inches and a diameter of 14 inches. The letter "1" means the shape of the bead flange. A feature of a deep-bed rim: in order for the tire to sit better, there is an elevation (hump) on one shoulder of the rim along the perimeter. When driving quickly on a turn, it prevents the tire bead from slipping off the shoulder of the rim in the bed.
