Tires tire pressure

Can anyone tell me what pressure the loaded rears on my 3016/1526 should be? R4's they are. Tks.

My 2615 has loaded R4's (15x19.5) same as yours. I run 16-18 PSI. That gave me the best full contact tread pattern in snow and dirt. My LS XR3037HC has larger tires that are loaded and i still run the same 16-18 PSI in them.

Loader , backhoe, snowblower, mounted plough? 12psi is a good place to start.

Fel, bh

You may need to adjust the PSI in the rear tires if you have the BH on or off. With the BH on you have a lot more weight on the tires and at 12 PSI the rears may look low and not have a good tread pattern on soft ground.

12psi is the minimum for bias ply farm tractor tires. Said it was a place to start.

Have been running 11 psi in my 4110's rear loaded tires for 15 years (R4, 16.9x24). This pressure gives my tractor an ideal footprint with any implement I have ever used on it (no backhoe, though). I run my front R4s at 38 psi (fel).

I'm concerned that if pressure is too low, the wheels might spin in the tires under heavy traction loads, tearing out the tube stems. In my mind, with under 20 pounds it seems like that might happen. The tires say not to exceed 32 lbs.

I went through a lot of issues trying to figure out inflation pressure for my max with turf tires which isn't listed in the manual. Contacted the dealer and Mahindra and they both said to use the max pressure listed on the sidewall which I know from the automotive world is wrong. The number on the sidewall is the max pressure for the tire at the max rated load. Tire manufacturers have load vs pressure charts for their tires. THe link is as an example for titan tires. http://www.titanstore.com/pdf/LoadandInflation.pdf . So when I have the FEL and BH on. I'm getting close to max load and pressure on the tires. When I only have the MMM on I air way down to around 12 psi because I've taken off close to 2000 lbs of load. Also explains why your truck/car tires have a max inflation pressure of 45 psi but the sticker on the door says 35
