Keeping your tire pressure at the recommended level helps them last longer, helps your car handle better and safer, and helps you save money on fuel. To learn the correct air pressure for your specific tires, refer to the Tire Label inside the driver's-side door or your Owner's Manual. If the pressure of your tyres is too low, you can use an air pump to inflate your tyres. You can do this at home, or at petrol stations that offer an air pump. In the event that the pressure of your tyres is too high, you can remove the dust cap and carefully release some of the air in the tyres. Make sure that you do this slowly and carefully The tyre pressure monitoring system in the Ford C-Max is activated when the car is started. If the system detects that the pressure in one or more tyres is low, it will illuminate a warning light on the dashboard. In most cases, the warning light will be yellow or orange. Name: Nick. Ford Model: C Max. Ford Year: 2018. UK/Ireland Location: Please Select. Posted February 17, 2021. Hello all. I have a 2011 C Max 1.6 TDCI Titanium. Its tyre pressure warning light is on. However when I go to driver find assist on the menu it is not there so cant reset. Your Ford C-Max has a tire repair kit in the back of it instead of a spare tire. In this repair kit is a small compressor and a canister of tire sealant. This tire sealant has an expiration date on the can and that will let You know when it expires and should not be used to fill Your tires. Your vehicle has a tire mobility kit service reminder, to remind You to change out the can of sealant Maximum Inflation Pressure. When tire pressure is increased, the load carrying capacity increases to a to a pre-determined point. This point, the maximum load capacity, is what the manufacturer designed it to be. So for our P-Metric P275/65R18 tire the sidewall says Max Load is 2601 lbs. and Max Pressure is 44 psi. The Fusion’s ideal tire pressure is 35 pounds per square inch (PSI), but drivers should keep their tire pressure 3 to 5 pounds higher (38 to 40 PSI) throughout the wintertime months since the lower temperatures may cause the PSI to decrease more quickly. For the steadiness of the tire and to make up for the loss of sensitivity, this slight Hi Jim, 80 psi in your 4 rear tires will give you over 11,000 lbs capacity, which is way over the max rear axle weight rating of your truck. 65psi is what Ford says you need to run at the max weight, and I don't think you'll even come close to that with the hitch weight of your fifth wheel. For example, while a P-metric sized standard load tire's maximum load is rated at 35 psi, many P-metric sized standard load performance and touring tires are designed to contain up to 44 psi (and are branded on their sidewalls accordingly). This additional range of inflation pressure (in this case, between 36 and 44 psi) has been provided to The rule of thumb is for every 10° Fahrenheit change in air temperature, tire pressures will change about 2% (up with higher temperatures and down with lower). This means that light-duty, standard-pressure tires (typically inflated to 30-50 psi) used in applications on cars, vans and light trucks will change by about 1 psi; where heavy-duty LnBvdst.
