I been to Michelin in SC and Bridgestone in TN and few other,the people in SC at Michelin are very well versed so are the Bridgestone people.
With tire manufactures using different compounds you kinda to need to go with the manufactures recommendations.Buse now are heavy you have trucks on the highways weighing 70 to 80,000 lbs loaded running on 18 tires then you have a bus weighing 52,000# using 8 tires.
I am like my buddy Gary when it comes to the Michelin bus tires,they warranty the tire for 10 years and then want you to replace the tire at 6 years what is up with that deal. 
Grin Gary is so paranoid about the Michelin's on his Prevost he buys a new set every 4 years but it makes him feel safer so I just smile.A 2010 model with less than a 100,000 miles on his second set and shopping for a new set of tires  Shocked

Hey guys,
I wanted to post this link to maybe the best tutorial of rebuild of a Eagle Bus I ever seen.  There is over 400 photos to enjoy and I sure did.  It brings back many, many memories to me.  anyhow hope you enjoy this labor of love to resurrect a Eagle the right way.

Most of us will not wear the tread off our tires before they get to be too old. When I bought my Model 10 Eagle last year, it had several brands of tires on it that were 13 years old or older. The youngest ones were Dunlops that had lots of tread and looked good. The rest were mostly Michelin's with some sidewall cracking, one even had a three digit code, but they all held air and made it the 160 miles home from where I bought it. I had them all taken off, and had Dunlop SP160's put on. The two Dunlops that were on the front (13 years old) passed inspection by the dealer who said they were okay for spares. The corker is that the old spare that was behind the front bumper was also a Dunlop with a three digit code making it twenty something years old, and it was holding 100 psi. I think the current wisdom that tires are unsafe at seven years is not necessarily so, and is primarily being put out to sell tires. (Similar to stores saying your bed mattress is no good after 8 years - horseradish!).

I think a more reasonable life is more like 10-12 safe years, subject to monitoring tire pressure, checking for cuts and cracks, minimizing exposure to the sun, and running them on a regular basis to exercise them. I had heavy trucks for years, and sure enough, a truck radial could blow at any time, but they were loaded much heavier per tire. A blown tire does not automatically mean you are going off the road. In the case of that RV that crashed and burned, do they know for sure a blown tire caused it? There were no survivors, and the RV was destroyed in the fire, so unless there was a close witness, I wonder how they concluded that? For me, I will stay away from Sticks & Staples, good tires or not.

I put in a VDO 30 PSI boost gauge a few years ago, and it uses almost 45 feet of 1/4" non-DOT plastic air tubing and a few feet of 1/4" refrigeration copper tube.   I underestimated how hot the air is after the turbo and melted the DOT push-in fitting's O-ring and the plastic tubing, so now I have a compression fitting there for the copper tube:  no more plastic to melt!   The gauge reads almost instantly, proving that using air line is OK even in a 40 foot bus.

I like to use the boost gauge when climbing long grades.   I can comfortably climb a steady 6% grade in 3rd gear at 1900 RPM with about 18 PSI of boost on a 3/4 pedal, but if I work the engine harder the temperature will rise.

I think what he means is that the coach was converted in 1965.  This same request has been made on Facebook with more information about the coach.

FWIW & HTH. . .


Ah.  As always, I never seem to have all the info......

Dateline  -  Aguascalientes, Mexico

I've got some more info about the elusive 4104 that I saw last year at the bus station here, apparently still in service.   A few days ago I took the Primera Plus service from here to Mexico City, and while waiting to get my bag of food and goodies before boarding I asked some Primera Plus staff about the 'muy viejo camión GM Americano'.   Amazingly one of them knew of it, and he said he thinks it runs only during the annual fair here, the Feria de San Marcos (maybe the largest fair in North America), possibly as a relief service to one of the smaller towns near here.   He said he's not seen it at any other time except then.   Unfortunately I'll be gone from here before the fair starts this year, so there's no chance of my finding out more for now  -  last year I was here during the fair, hence my sighting of it.   If I could ride it to wherever it goes, wouldn't that be fun to be in a 60 years old GM still in revenue service?   I saw an Eagle at Tijuana's Central Camionera a few years ago, still in service and sounding good with its 8V71.   Who knows what other gems are still in service here?   I did see a complete-looking DINA Olimpico in a truck junkyard here, so if anyone's looking for one you know where to go!

I'm off to Tampico tomorrow for a few days, so I'll keep my eyes open for anything else interesting.

So, since you're doing the math, what's the chance of failure on a 17 year old tire? Curious minds want to know.   Huh

Don't know, don't care, 'cause I ain't gonna use any that old. . . .  Grin

I might be wrong, but I don't think they made 4104's in 1965.

How many side windows are in your coach?
How many open?
How many times/how often do you open them?

Six total not counting driver side or front door - four emergency windows, two sliders, all open. The sliders with screens are opened for ventilation in good weather, but they are all serving as emergency exits in addition to two roof hatches. Beyond letting in light, their most important feature is as exits.

Rubber compounding is a complex art.

Knowing the exact life expectancy of ANY manufactured product is impossible, so we deal with percentages.

What if the following were true -  
97% will last 10 years,
99.9% last 7 years,
99.99% last 6 years,
99.999% last 5 years

For the best case scenario of a tire failure on the road -- the replacement tire will cost about double the replacement cost at home plus collateral damage. AND THAT assumes the vehicle stays on its wheels & is still usable.

Now, consider it a different way - you have your choice of tires for your trip, are you going to choose one with a 0.0001% chance of failure
-- OR -- the one with a 3% chance of failure.

So, since you're doing the math, what's the chance of failure on a 17 year old tire? Curious minds want to know.   Huh
And NO, I put new rubber on our coach just a couple of years ago.  Grin
