Tire Pressure Question July 12, 2021, 05:57:19 pm Finally got an opportunity to weigh at a Cat Scale. Until we can get a four corner weigh, can we just divide the axles weight in half and use those numbers to figure the tire pressures for now? Here are the results:Steer Axle: 4,300Drive Axle: 8,940Total: 13,240Here is the chart. What pressures should I run for LT225/75R16, Agilis Crossclimate tires? I'm thinking 60 psi in the fronts and 72 psi in the rears. Am I on track?Tire Selector | Michelin RV Tires
Re: Tire Pressure Question Reply #1 – July 12, 2021, 07:16:37 pm A few weeks ago, Larry posted this link; it may be helpful to check the tire pressure information available in this Michelin PDF:https://michelinb2b.com/wps/b2bcontent/PDF/RV_Tires_Brochure.pdfA suggestion: LDO forum members often post links to tech information, products, procedures, "how-to, and (to) several other topics that are very useful to LD owners. I doubt that I'm the only one who does this, but when a poster provides a link of interest or value to me, I add it to an appropriately-categorized file (created on my computer). This way, I have the option of quickly reviewing a file category to find the link I want or using the forum search function to find additional or corroborating information. (I periodically update the link files for currency.)Saving useful/relevant links in an easily accessible location is usually very helpful in avoiding "wheel re-invention" and multiple requests for the same information.As always, YMMV.

Re: Tire Pressure Question Reply #4 – July 13, 2021, 09:07:01 am To answer one of your questions, the four corner weight is good to help you balance your load but you would still divide the weight and have all the fronts equal and all the rears equal.
Re: Tire Pressure Question Reply #5 – July 13, 2021, 09:50:10 am Assuming that you were at your maximum traveling weight on the scale then, yes, I think you have this about right. But if not, then you might want to bump those up a bit, perhaps 65/75, to give you some room for added weight. A bit more in the front (up 5 pounds in front vs 3 in the rear in my numbers) can give the front tires some added stability in corners.You don't want to be below the specified pressures for your weight, but a bit more can make some sense. I'd judge how much more by how the coach feels. A bit more may sharpen up the handling somewhat, but too much more and you'll notice a harsher ride. 1 Likes
