| On my Dodge PU, the tire pressure for general use is about 1/2 the max pressure on the sidewall. How does one decide how much to increase the pressure for towing? |

Your owner's manual should give you a pressure for loaded use. You up pressure to carry additional load. I would imagine this is a greater difference with light tow vehicles than with heavier ones like my F250. ------------- 2012 181G |

I use visual inspection. I don't like seeing the side wall pooching out. ------------- Cliff & Raelynn Ranger 4.0/178 (1/2 ton 5,800lb tow capacity) |

I always recommend full sidewall pressure on the pod, and within a few pounds of the sidewall pressure on the TV. I find the ride gets harsh if you go to the max on the TV. ------------- Doug ~ '10 171 (2009-2015) ~ 2008 Salem ~ http://www.rpod-owners.com/forum_posts.asp?TID=1723 - Pod instruction manual

I have never raised the tv tire pressure for towing. The transferred/carried weight is less than if I had the passenger seats full, (by a long shot) and I wouldn't bother to raise the pressure just because a half dozen of my friends were going to get pizza with me.. ------------- |

Expeditions are bigger than I realized. There's no way to talk about a half a dozen people in my FJ. Especially with the back seats out! Anyway, going to get pizza and towing a trailer 600 miles are two different things. But I agree with you. I've never adjusted my air pressure either. I haven't checked my hitch weight, but figure it's close to 300 pounds. It is right at the end of the truck, but that affects suspension more than tires. 300 pounds is equal probably less than two people. Still, it's a judgement call. A few extra pounds of air in the rear for towing would probably be a good idea. TT ------------- 2010 176 FJ Cruiser |

I go plus 5 psi in the rear tires when towing. It's actually in my owners manual. ------------- 2017 ATC 7X20 Custom Toy Hauler 2013 R-Pod 177 (SOLD) 2013 VW Touareg TDI |

I measure tire wear when rotating tires, and adjust pressure as necessary. When adjusting I never vary from manufacturer's recommended pressure more than about 10%. I normally rotate tires with oil changes. I do inflate tires to manufacturer's maximum specs when towing, then readjust on my return home. ------------- Old Dingo and/or Mrs. Dingo 181G 2013 Jeep Grand Cherokee |

When starting on a trip that will put me on the road for several long days of driving, I start with a few pounds lower than the max. I have found that during the summer, you get those pounds back as the temp goes up. Gas laws. ------------- Marv-N-Kathy 2015 179 RPod 2016 Chevy Tahoe |

IIRC, tire pressures are spec'd when cold. Which suggests that expansion due to heat buildup from driving is engineered in. ------------- John & Teri Tundra 5.7L V8 / RP 180 E2 WDH / Integrated controller (POS) replaced by Tekonsha P3 |

+1... Cold pressure is the way to measure. It is anticipated the pressure will rise when they heat up, and the tire makers and vehicle builders plan accordingly. ------------- 2017 ATC 7X20 Custom Toy Hauler 2013 R-Pod 177 (SOLD) 2013 VW Touareg TDI |

Open the drivers door on you t.v. and there is a label with the recommended pressures for your vehicle, I use R Pod recommended pressure on the Pod. ------------- Dane and Donna Smith 2011 RP-172 2008 Chevrolet Trailblazer 4X4 lift kit prodigy wireless brake controller |

From the Car Talk web site: "How do you determine the correct tire pressure for your car's tires? "A lot of people check the pressure listed on the tires themselves, but that's actually the wrong place to look. The number on the tire is the maximum allowable air pressure — not the recommended pressure for that tire when used on your vehicle. "The recommended tire pressure is almost always lower than the maximum tire pressure. Check your owner's manual to find out where to look on your vehicle to find the recommended measurement. This number usually is indicated either on the driver's door pillar, the glove compartment door or sometimes on the gas filler door." Tire manufacturers' web sites make the same recommendations.Also from Click & Clack, "Car Talk Tip: Check your tire pressure even if your tires look fine. Radial tires can be deceiving (they're sneaky little guys). They may look fine even when they're down 10 pounds of air — or overinflated by 10 pounds. So don't trust your eyes — use your gauge."

Tires are rated to their maximum carrying capacity when they are at their maximum rated tire pressure. The rating on the door pillar sticker is the one the manufacturer recommends for the best passenger ride balanced against mpg and driving performance. Basically, they need to ensure people don't complain about a harsh ride but they need to boost their fleet mpg rating as much as possible, too. It is not the correct pressure for towing, when you want the least sidewall flex to prevent trailer sway and you are loading the tires much closer to their individual capacity. Just because the pod's static tongue weight is ~300 pounds that is not the dynamic load it applies to the TV going down the road as it hits bumps, it can be several times that. These same reasons are why a trailer's tires also need to be at their max rating - they are often loaded to the edge of their weight rating by the camper's design, and you don't want them to flex which will amplify sway.

| Now, that makes sense. Now that you mention it, I knew that but I somehow disremembered that. I used to pull a 11000 pound horse trailer, and one needed all the air pressure that would fit to cut down on sway if a horse started moving. I had one mare that absolutely would not tie in a trailer and had to be loose. |
