I would appreciate hearing what the tire pressures were on a late model Aspire after all tires were individually weighed. I will be getting those weights on my own unit but want to hear what others are learning. Thanks!

After weighing we run.
Front 110 PSI
Drive 90 PSI
Tag 90 PSI

Based on individual axle weights and Goodyear's latest website recommendations for tire pressures, we are using 105 in the front and 85 on all rear tires.

Thanks you for your posts.

Those readings are in the range that I expected. Even though we are full-timers, we try to keep it minimal on the "stuff" we carry. I plan to get our unit weighed at the Good Sam Atlanta Rally by the RV Safety folks.

Should I be using the Goodyear website numbers or Entegra numbers?

Here is a shot of my plate inside the MH

Spartan says to use the tire manufacturer's figures.

I used Michelin's chart numbers on our '06 'Bago Journey. Did the same thing you are doing, weighing all four corners. The sticker called for 110 all around but based on the chart I could use 95. I had Smart tire on that rig which monitors air pressure and temperature. It worked perfectly. The tires didn't heat up and the ride was much better. Remember to use the highest chart number for each axel. Adjust the pressure from the 'cold tire' to the ambient temperature of your tire. 'Cold tire' is 65 degrees. If your tire is warmer you'll need to adjust the pressure up. Stop and check your tire temperatures often until you are confident that it is right.

Just my personal experience. I do weigh my MH loaded for each trip. There is a State truck scale at the on ramp where I get on I-75. I use the manufactures weight table and add 10 PSI if not over loading the tires. I still get a nice ride, no chance of being under inflated and allows for DW's shopping trips.

I bought this and moved it from my last coach to the Aspire. I like that it checks pressure and temperature.

X2 - but left it on the old coach and bought the new model. I know there are other good options - we started here and have had great service so we stay here.

Just installed the TST 507 unit with 12 sensors and a repeater -- I really like it.

This thread has drifted a bit from my original post so I am requoting the point. I did get individual weights of each wheel at Josam's Alignment in Orlando. Based on those weights and the posted on-line pressures shown for Goodyear G670 RV tires, I came up with 110 psi for the front tires and 90 psi for all six back tires. My point is that the on-line chart shows the minimum inflation for the 275/80/22.5 to be 90 psi--no less--regardless of weight. For anyone interested, the heaviest side of the front axle was 7100 lbs, the heaviest drive axle side weight was 9000 lbs. and the heaviest tag axle side weight was 4200 lbs. The heaviest front side was on the driver corner and the back two axle sides on the passenger side were the heaviest. The side to side difference on any axle did not exceed 650 lbs. which is acceptable (I am told). Since the kitchen and washer/dryer are on the back passenger side, the weight difference makes sense and since the propane tank is just behind the driver front tire, the weight difference there seems logical.

Big Mike at Spartan said if the weight difference is less than 1000# on each axle, you're good to go, and 1500# wasn't that bad (although 1500, JMHO, that seems high and you might be able to adjust your loading). Mike then offered, choose the higher tire pressure associated with the weight.

Hi Curt...I know the coach has 8 tires so where do you strategically put the other four? I know there would be a purpose for this. Sorry to hi-jack but I was just curious.
