Correct tire pressure?
Never really understood this. Is anywhere between 36 and 12 psi OK? I have them at 20 psi.

Re: Correct tire pressure?
LOL. I think the problem is the 4th line down on that tire. I run mine at 23 never had trouble.

Re: Correct tire pressure?
36 psi is setting the bead only , 12 psi cold is your for your driving pressure. If you find 12 psi is to low you can always do a the chalk test.
Chalk a 2 to 3 inch strip across tire , drive 20 to 30 feet , check wear mark. inside wear pressure to high , outside wear pressure to low . |

Re: Correct tire pressure?
The max 35 is for bead setting, that’s when they put the tire on to rim and fill it up to mount against the rim. Max 10 seems a little low to me, but it is a china tire. I would run it down the road and see where it drives. If only the middle of the tire is dirty, that means your going to wear out the center, and should drop the psi so you are driving on the full width of the tire

Over-inflating tires to seat the bead in the rim during the mounting process is a common practice and in this case, the tire manufacture is saying their tire might explode if it is inflated to more than 36PSI. That seems to be a mighty low value and I'm not sure if it is just ultra conservative or their tires actually are that flimsy, but I wouldn't operate the cart with the tires inflated to 36PSI because tire pressure increases during operation. I'm not sure why the picked 12PSI, but max loading depends on inflation pressure (and other factors). If your cart, passengers and cargo weight less than 1,456lbs, you can run at a lower pressure. With higher pressure, you can carry more weight. Also, with lower pressure you get a more comfortable ride, but lower top speed and less range. Conversely, with higher pressure you get a harsher ride with better range and a greater top speed. For maximum tread life, you want the tread flat on the pavement. Too little pressure and the edges wear more than the center and too much pressure causes the center to wear more than the edges. Since tread wear isn't a major issue to me, I go for comfort. |

Re: Correct tire pressure?
As others have stated. The higher pressure stated is max for seating the bead during mounting only. The lower pressure is the max operating pressure and max weight of vehicle and load per tire. 12psi is not out of line for a tire that can only carry 350 or so pounds.
The front tires on my cart are rated for only 250lbs and 5 psi operating pressure. My rears are 20psi and 1,000lbs each. I carry heavy loads and frequently pull a trailer. |
