This question has been asked before and received every possible tire pressure, everyone was an expert. Im not here to teach golf car repair but rather inform and let the consumer decide on what is best for them.
I know, for a fact, that a 205x65x10 tire will not wear out the middle if set at 35 psi, I work on 1000s a year, customer would complain, instead they praise that their tires last so long.
Its your cart, you do whats best for you.

That’s good cause nearly nobody inflates them on golf cart to 35 PSI. That’s only the MAX pressure the tire manufacture recommendations. Most customers don’t have clue and you know that.

There are those that put their tire pressures at 35.

Im wondering who runs there automobile tire pressures 30 percent below what it says on the side wall.....Ill wait..

My neighbor just bought 4 brand new golf cart tires WITH NEW RIMS off Amazon, delivered for $50 a wheel. Changed them himself in hardly any time with a scissors jack. Very easy. Just another option to consider. He is very pleased and they look great.

Interesting in that my 2017 Yamaha cart has almost 600 hours on it and the tires are half worn. Tire pressure at a consistent 22 lbs. is the key. Just to add, I also have a 2011 Yamaha with the ORIGINAL tires that I am just now replacing. Both are the 10-inch Loadstars. Terrific trailer tires for a golfcart!

Is this too much PSI
 

Now I am worried that I have too much PSI in our tires.

Must of been 8 inch’ers?

Golf carts weigh less and don’t go down the road at 80 mph plus. The car manufacturer determines tire pressure. The tire manufacturer determines max pressure. But you knew that right.

So you got bad back?

Great price. Wheels alone, on most new carts are in the $600 range

Oh my bad....

Well, then I guess we need to run our bicycles tires, motorcycle tires, wheel barrow tires all at 30 percent below what the tire manufacturers recommend or does it only apply to golf cars? Again, Ill wait

No, you should run it soft like that, its good for the tire and if its electric, it doesnt drag the batteries down or anything...looks good.

The problem with the proper PSI for golf carts is that they have more than one use. If someone doesn’t golf, and drives their cart exclusively on pavement, then 35 PSI would be the way to go. If one uses their cart exclusively for golf and drives mostly on turf, the low 20’s would be more appropriate. Many Villagers compromise for the different uses by airing up to 28 - 30 PSI. My ATV that I ride up north in the woods over rocks and through mud and snow is optimal with 3.5 PSI for that type of terrain. It is recommended that cars up north run during the spring, summer, and fall at or near the maximum rated PSI for the tires, but that the PSI is dropped to about 22 - 24 when driving in snow during the winter for better traction. When I air down the tires on my truck and put it in 4WD to oversand (drive on the soft sand beaches) at Race Point in Cape Cod, I go to 11 PSI. They have air compressors at the exit point so people can fill their tires back up before hitting the road. The point is, optimal tire PSI depends on what conditions the vehicle is navigating. There is no “one size fits all”.

Tire Pressure gauge
 

======================================
I've had my cart 4 years and tread still good. As with all tire wear, good tire pressure is important. I bought (on Amazon) valve stem tire pressure gauges (lowest they had was 26 lbs) normally used on cars. This makes it very easy to check the pressure by just walking around the cart - green good - yellow time to add air - red really time to add air. I also have a rechargable hand held tire inflator where I can set the amount of air and just turn on and it turns off when that pressure is reached - very easy.

I take it back, don’t know that.
