Step 3:

Activate the mechanism, maintaining pressure on the plunger for approximately 4-5 seconds. After this interval, release the mechanism, and restart the process after a 5-second pause.

Step 4:

Step 5:

Now you can go ahead and put the wheels backs on the mower. You may begin moving right away if you want to perform so.

2. What are some of the benefits of foam filled tires?




  •  They cannot go flat; there is no air force within to leak out.

The same for a 12 x 16.5 tire will be 205 lbs, and for 4 tires, the full volume of foam needed will be 820 lbs. that is what provides extra stability to the vehicle and make it an excellent choice for rough terrains.

7. Is foam bad for tires?
