Good advise. Happened to us also last March. I had a spare, but I did not have the jacks, but Roadside Assistance did. I ended up getting 4 new tires once we reached our destination (Indianapolis to Charlotte NC). We purchased the trailer new only 6 months earlier.

I carry 1 drive, 1 steer for my rig
Hmmm.... drive and steer use the same wheel and tire. One standard steel wheel spare covers both, even if you have alloys. What chassis model and year do you have?

The Toyota chassis from the 70's through to 1986 was the only chassis that had different front and rear wheels. I know because I owned one for 24 years. The DRW axle came years later through a recall, introducing the difference from the front wheels.

RV'ers seem to be mislead on proper tire inflation pressure. I have been accused of trying to act like an expert on this. I have found a video by Michlen tires that explains how to weight the rig and use a load and inflation table for PROPER inflation of the rigs tires. So it is no longer my experience and opinion, it is by Michlen who may just be experts on tires.

I do not much care what Randy the RV guru said, I will listen to Michlen. They also have a couple good videos on RV blowouts.

Disclaimer, I do not know if anyone here is named Randy and if so it was not directed towards you, only meant as a pun.

Glad you got it fixed safely. I don't know what your individual corner weights are, but that doesn't sound like enough air pressure.


I always inflate {and adjust} for the load I will be running as it can vary by almost a thousand pounds depending on whether or not {and what} we are towing/loading. We often run at or very near our max GVWR of 11,500# {I have a 2011 E-350 chassis - the coach is a 2012}. I have 3,800# on the front axle and 7,700# on the rear. Per the Michelin load/psi tables I run at 65 psi front and 75 rear adding in a 10 percent fudge/safety factor. The ride and handling are awesome. I am running HD Bilsteins and tow with my air bags at 50 psi with excellent results.

Running the fronts on most 25' or less Class C's at 80 psi per the door stickers {which are a bad joke}, will reduce the contact patch to the point that it will handle like a pig on skates and be blown all over the road by passing trucks and/or cross winds. Putting 80 in the rears would be serious overkill las at 80 they are rated for 2,640# of load X 4 = 10,560# to carry a 7,700# load. This also creates a very stiff ride that will beat you to death and shorten tire life.

Miners, chukkar hunters and people driving to Alaska usually carry two spares.

I have had three flats in one day or two different occasions. Sharp basalt is the worst.

Most Michelin tires for a 25' or less Class C would have a load rating of 2,470# in a dual wheel configuration. Please provide the tire size.

Desert Captain, thanks for taking the time to share your story and posting the pics.
When we were class 'c' shopping last year, a spare tire as OEM equipment was a must. We too use CN road service and have been happy the 2x we had to use it.
The way you handled the roadside safety was textbook professional.
I'm glad you are both safe and that's the real bottom line. [emoticon]

My rv did not come with a spare and I made sure that I got one along with a carrier at the rear. Friends with a similar rv snickered at the thought of me having a spare tire and having to change it myself. Well I'm 76 years of age and haven't figured out that I'm supposed to be old and feeble yet. When I have to change tires I just deploy the BigFoot jacks and wrestle the tires off and on. Not a problem!
