Max weight of tires?

Question

In my tech class I am building a sofa vehicle. I went to canadian tire today to buy tires for it, and I found some wheelbarrow tires tha said max weight 300 lbs, does that mean that each tire is 300 lbs, so if i had 4 tires would it be 1200 lbs? or does it not change no matter how many tires there are?

Answer 1

Max weight shown on a tire is the weight that the tire will carry...If you put 4-300 lb capacity tires on an object that means you could carry a total of 1200 lbs on the object....If you have dual (side-by-side) tires, you could carry double the weight.

Answer 2

max weight 300 lbs per tire i think you would want something better if its going to be drove at any kind of speed

Answer 3

the "max weight" is the amount that each tire can support.

Not what each tire weighs.

Answer 4

your right wheelbarrow tires weigh 300 pounds each and don't forget to add another 25 pounds when you put air in them.

Answer 5

It means that each tire will support 300 pounds.....

Answer 6

in theory your max load is 1200 lbs, but keep in mind that this load is variable due to the fact that the vehicle is influenced by other factors....for ex: when cornering the G force adds to the load....and also when the wind is blowing....so be sure to leave a safety margin.....If I were you I wouldn't exceed 800 lbs

Answer 7

its three hundred pounds each for a total of 1200 lbs but remember on a moving item if you are at 1200 lbs and you pass over high spot that lifts a tire now your 1200 lbs is on 3 wheels which is 400 lbs each, cornering loads the outside wheels etc so be sure to leave yourself a decent margin, although I assume this is not meant to be a fast moving project?
