The weight of a car roof box will depend on several factors and an average can only be computed based on similar materials and sizes. Many are made with the same plastic materials but the thickness will vary and therefore the weight will vary as well. A 6 cube foot box made with industry standard thickness will weigh an average of 35 pounds.
the average would be around 9,000 pounds. I know this because I have tested it for a science fair project
it is 1.5 to 2tons
3000-4000 Pounds
1550 kg
90 lbs
Depends on the type of car. the average small car is under 1 ton
A car that has no roof is merely roofless, but the name for such a car that has a retractable or removable roof is a convertible.
A good average weight for a car is 1000kg, but with a range from 500kg for a small car, to maybe 2000kg or more for a hummer.
The roof
I would have to guess that the average weight of the entire wheel (tire and rim) for a car is around 20 lbs. For a truck, maybe 25-30.
no <><><> The first car did not have a roof at all.
It depends on the car but the average car weighs around 1 to 2 tons
