Tire Pressure?

[Ox]

An often asked question: What PSI do you run your tires at?

For Volvo 610 (and other Class 8 trucks)owners, I'm curious on what your actual run pressure is at. Opinions and data are abundant, real statements are rare.

Hi Chris,


For no scientific reason, I run 90 in the fronts, and 85 or 90 in the rears. Full inflation is not required because not much weight is carried.

Have you had an opportunity to tow any significent distance yet? Are you using the factory hitch, or did you install an air ride hitch? (End of interrogation)

Chris:

Michelin on their web site has an iflation table, for various tire size and location (steer/drive). They also have an rv only for very lightly loaded tires.

I run 90 in front, and 85 in the rears and could go lower according to the charts.

Thanks for the info. Confirms where Suzy Q seemed to want the pressure set to.

onzeman: did a test run to California. Only a 600 mile run over a weekend. Wanted to check and see how things were working and catch problems before the planned big trips happened.

Still running the stock hitch. Pulled the trailer loaded with bikes without issues. Nate took his turn at it also. Great trip.

I am also partial to the 420 cab for what I want to do. Problem is they aren't nearly as common as the larger sizes. And good luck finding a day cab with any sizable wheelbase!

Hi Gary
My truck came from Georga, it was a "Little Debbie truck" itwas maintained by Ryder which made the sale for me .
Trucks are mostly used back east for regional over night runs .
Went to Washington on a trip and counted ten or so carriers were useing on I 5.

 

[Gary Atsma]

Hey Tom-
Sounds like you got a good truck, as Ryder knows how to maintain 'em. I think warpath's truck was also a Ryder. Only thing with his was whoever drove it smoked like a train. Like Lynyrd Skynyrd sang, "EWWWWW that SMELL!"
Take care! Gary

Tom,

I like those 420s too. Lot's of them are used as car haulers. With that flat roof, a car can be hauled over the cab too. What State did you register in, and how is it registered? If registered commercially, what does your insurance cost? I think many States would not register them as motorhomes.

I looked at a 420 when I was considering a Showhauler Conversion......I think I will go with a 610....I wish a 770 table and couches ,that fold into a bed, would fit in a 610 but they won't....so I think I'll stay with the stock 610 interior setup....I got to send more time looking at stock 610's or unites that have been converted to RV Haulers....geof

Hi onezman
I Live in Medford Or. it was Nov. reg. as truck 170 $ (30$) for third axle (one time only) can pay quarterly if we want . Insured with gmac as semi for non commercial use under 500$ a year no collision. Motor home reg. would be challenge not because of 420. DMV says no cdl if no pay . I have been from Washington to Arizona no scale stops yet. What fun these trucks are thankyou for all your shared experiences, they helped me tosee the light

Hey, Chuck - Couldn't find the air pressure charts you mention on the Michelin site. Can you give me a full URL? thanks - Joe

Joe:

The Michelin site is fairly user hostile. The chart is a download, and you get to it by:

www.truckus.webmichelin.com

when the site comes up and it takes awhile to completely load, go to the banner on the left side go to: information
Bulletins
new tires
technical bulletins
and then scroll down to rv tires air pressure etc.

Lots of good information on their site, they just don't make it easy to get to.

Hope this helps

Chuck

 

[JoeHDVoyager]

Thanks Chuck. I'll check it out. I've got recaps on the rear axle so I'm a little concerned about not being underinflated. Joe

Okay, Chuck - Am I an idiot, or are we playing a game of "stump the dummy". I can't see anything on the site titled "rv tires air pressure etc." Lots of other stuff there in the drop down menus; but nothing like I think I'm supposed to be looking for. Are you talking about the bulletin on motorhomes? This string started out with a question regarding tire pressures on Volvos and other Class 8s. Is that the information your trying to lead me to, or are you talking about motorhomes? Thanks - Joe

Joe,
I think he means Information-->Bulletins-->New Tires-->Technical Bulletins-->Motorhome Weights and Tire Pressure.

 

[chuckd]

Joe:

James is right. If you look at the section on motorhomes they have tire pressures for 22 and 24 inch tires. Sorry I didn't get the last title correct, forgot to write it down which is a huge mistake for me to make.

Chuck

 

[JoeHDVoyager]

Okay, I am "the dummy". I went to the "Motorhome Weights and Tire Pressure bulletin and all I see is a two-page PDF file that shows sketches of how to weigh an RV. There's absolutely nothing that I can see on these two pages that refers to 22 or 24 inch tires or air pressue. So, just call me a lost cause on this one. Thanks anyway - Joe
