Tire size question

[Bussinit]

Thank you everyone for the information. I don't like running so close to the max load capacity of my 11R's so I will be ordering a set of M144s in a 295/80R22.5 for my steer axle. According to Toyo's RV inflation table I will be able to drop down to 100 psi.

Another question comes to mind. My current weights are 6375/6525 lbs in the front. These correspond to 95 and 100 psi. Am I correct in assuming I should go with 100 psi for the axle, even though this is a little overinflated for the 6375 lb side? And I've also read about adding a little pressure over the chart amount (10-15%). Is this another thing to consider or do I just stick with the chart?

Thd general rule is to keep all tires on the same axle at the same pressure. In your case it would be 100 psi plus the 5-10% safety factor most use. It's not really a safety factor, as the tire isn't any safer with 10% higher inflation. It's to account for lower morning ambient temperatures so the psi is at or above the minimum required.
