Answer: Yes. With cold temperatures the elasticity of rubber sinks. Heavy vehicles that are parked outside in winter often don’t run smoothly on their first kilometers the next morning. If this problem is solved by itself after a short time then everything is fine. Should the ride still be rough one should also think of defect steering shock absorber or objects that may stick in the tire.
Answer: The more the tire has been deformed due to long periods of standing still the higher is the danger of constant defects of the material. Drivers of campervans know that it can be a long and rough ride.. Should it be over after days or weeks the campervan goes back to the garage already. It’s a torture for the wheels. In the end it affects the durability of the tires and costs a lot of money to replace.
Answer: As a matter of fact it’s the diagonal tire. The reason is not based in the general type of construction but in the used material. Nylon fabric in combination with thermoplasts. Nowadays’ radial tires are more resistant against flat spots as long as they are not high speed tires. The softer the rubber, the flatter the profile, the higher the risk of getting flat spots. In the end the crucial point is the period of standing still and the contact pressure.
Answer: If you want to save the money for air pillows you have to invest time: Either you drive your vehicle regularly or use a set of old and used tires for the time of standing still in the garage. If in that case a visit in the workshop is needed the costs for the flat-jack® air pillows will soon be compensated very quickly – not talking about the comfort and time saving!
Answer: In the case of jacking up a vehicle e.g. rubber parts on bearings and axles and the entire chassis are exposed to heavy load where it shouldn’t be.and that have not been constructed for such heavy loads. Damages on the suspension often result from inproper storage on jacks. The solution with flat-jack® air pillows is definitely the better way when it comes to safety and comfort.
