Help with Hanook Tire pressure

Ok I called their customer service number to get a tire pressure chart for different weights. Well guess what they told me they do not have one. So how can you put the correct air pressure in your tires. They told me to run what is on the plate inside the door. Which is the same as on the tires 80lbs. I have read you get a better ride if they are inflated correctly. Sounds like they want you to go out and purchase other brand of tires. Anyone have an idea where or if a chart is available? Thanks for the help.

I have a 2017 GreyHawk 29W and run my tires with 80 lbs in the rear and 75 in the front. I find the front way too rough at 80 lbs. I donít have Hankook tires and have Michelin, but that really wonít make a difference. My door sticker says 80 lbs also.

I have a 2020 Greyhawk 31FP. I also run 80 in the rear and 75 in the front Works good and gives a good ride. The 31FP is at max weight.

I run those same pressures on my rig, give or take a pound. The plate on the door says run those pressures, so I'm not going to screw around guessing at something else.

I have a 2020 Greyhawk 30Z and my tires are Hancock also with max pressure of 80. The door says 75 front, 80 rear. One thing right off the bat is just how close to GVWR the Greyhawk is out of the factory door. In my case, 13122, 1378 shy of GVWR of 14500. So throw in the wife and me, some cargo and some freshwater and before you know it your near GVWR.

What really got me looking at this is all the information out there about adjusting pressure to better meet your load. That assumes you have more margin between load and max tire pressure.

The point here is that for my Greyhawk and my load, Iím very near GVWR already, so 80 in the rear is the right pressure as recommended. No room for tinkering. As for a hancook pressure chart, I found one at tirepsi.com.

One note: I am heading to a cat scale soon to make sure Iím not over GVWR. With only 1378 lbs of cargo margin including the wife and me, it seems prudent to know.

Ride Comfort

Hi, I just brought home our new, and first, Jayco Redhawk 31F. I had a 140 mile trip home and had a question regarding ride comfort and tire pressure. The tire pressure was set per the door chart and it was not the softest ride. I am wondering if that is because there is nothing in it and I was the only person on board. After we load it and the family and dogs are on board will the ride smooth out a bit or do I need to drop the tire pressure? Thanks!

Use your own pressure gauge and make sure the pressures are what you think they should be. If it was the dealer who filled them, I would most definitely check them for myself. I run 75 in the front and 80 in the rear, and find that this is the best for me. I have a 29W GreyHawk and this is what is on the door sticker that Jayco put on the unit.

See my earlier post. You may have a yellow sticker showing your weight at delivery with a full tank of gas and a full tank of propane. The difference between that weight and your GVWR will show you how much margin you have to load up your family, supplies, and dog. In my case, I’m right at GVWR when loaded., so I use 75 PSI front, 80 PSI rear as recommended on the door. 80 PSI happens to also be the tire’s max pressure rating. For my Greyhawk 30z, I really have no room to run anything less than 80 PSI on the back because I’m at GVWR. In all however, weigh your vehicle at a cat scale to be sure you know your GAWR to help dial in a safe load.

Yeah, in our 31FK there's so little left over. It's silly.

I experiencing the same thing when bringing my rig home empty. Once you get it filled with gear, gas, water and people, that weight will calm it down and it will ride better.

Then you'll be onto making the necessary suspension upgrades to make it ride better.

One thing to note with the weight carrying ability in that chart. That is the weight for a single mounted tire. Weight rating at a particular PSI is lower when used as a dually.

Weight

If you buy a large Class C, 30' and over, there is very little Cargo carrying capacity. We are all close to max, or overweight. My 31FP has 347lbs of cargo carrying with a full tank of fuel. Add water, wife and I, 2 kids, we are over. Nothing I can do about it. Get a good tire pressure monitoring system, keep a good eye on your tires, drive smart and you'll be fine. To be honest, this is the best riding RV we've ever owned, including a big Class A.
