Prevo DFW
We left OKC Mon am headed for Prevo Proud rally in Orange Beach,Al and just over the Texas state line discovered a 12″ long wide and deep cut in the tread of the 365 RR tag. Called Prevo DFW to get the paper work started and to give them a chance to juggle and get us in. Jason did just that and we were gone in 2hr. Impressed !

Wow, sorry to hear about that.
How do you think it happened? Did you run over something? Tires reaching near the end of their life?
Safe Travels!

Mark, must have run over something. None of us (well, maybe Peter C.) ever reach the end of useful tread life. Tire was dated 33rd wk of 12.

George,
did you take 35 south from OKC? Remember friday or saturday night there was a bus accident southbound before texas line. Kids were killed. Trucker crossed median. Possible debris on road from that! Dosent help you much but it might be where you picked it up.

Bummer. Never happens to a tire that needed replacing does it!

While I think it is important to maintain pressures, monitor the tires for sidewall cracking, and to be aware of sounds or vibrations that might indicate tread separation, there is little we can do to prevent damage from road hazards. I have had them and most of us that have driven any distance have had them also. All we can hope for is that we are near a place where we can get a replacement tire.
Our tires are not the only thing that can be damaged. We followed a coach that hit a section of leaf spring from a truck and that heavy piece of steel punctured the transmission oil pan.

I am curious how much air pressure you guys were running in the tags.
Before I start a war on air pressure I am making my comments on my experience only. I read constantly on guys trying to get the ultimate ride and drive around with 80 to 85 lbs of pressure in the tag tires. Everytime you turn the bus the tag goes into a bind, the tire flexes and the less pressure the more it binds putting pressure on the sidewalls and thread. Our tag axles act no different than a spread axle trailer which I’m sure you’ve all seen. Look at a set of tires on a spread axle trailer if you get the chance.
I believe many guys ride around with minimum tire pressure and this leads to problems down the road, I’m not saying Geo and Corey did this, just my thoughts.
Trucks and buses are 2 different animals but we never sent a truck out that ran 250k miles a year with anything less than cold max inflation on the tire rating.
I wish Michelin would put out a chart at what pressure to run to achieve maximum tire wear.
I’m off topic, throw me out Godfather.

I have no opinion as to what others want to run in their tires, but as a rule I run what the Michelin chart says based on the weight, plus 5 PSI. The added pressure makes me feel good but I have no scientific reason for adding the pressure other than to make me think it will give me a little extra margin for safety. Kind of like BV adding max pressure.
From the seminars put on by Michelin and Goodyear that I have attended the pressures in the charts are what is required to safely carry the weight without damaging the tire, as well as providing the best wear characteristics, best ride, and best contact area for stopping and handling.
My tag axle tire weights are well below what the chart calls for so I just use the lowest tire pressure listed on the chart plus 5.
The only concern I would have is if a tire has been run at 20% less than the tire pressure stated on the chart for the weight carried, the tire manufacturers all agree that the tire is junk and should be scrapped. We don’t know if that has ever happened unless we bought the tires new ourselves and know the history.

Glad you got help G & C, at least you weren’t stranded.
Bernie – I’m 85 psi on the tag, but I do unload it for tight turns. Doesn’t even make the chart with Micheliin. I don’t think there is any comparison with a spread and our tag. At 6,500 lbs per tag wheel, no comparison to the weight of a spread.. Your turn driver….

We run 95psi on the tag. Geo.
-
That’s right driver, at weight per wheel the bus tag is worse. Do the math driver.
I am using a spread axle to compare our tag axle as to how a tire binds and flexes. If you have a better comparison or something we can relate it to, I will stand down.
Your turn driver.

I realize that unloading the tag for tight turns reduces scuffing, but I hope you all understand the scuffing of the tag is not much compared to the scuffing and side forces your steer tires take when making that sharp turn.
Next time you have to make a turn in which you feel compelled to lift the tag, step outside the coach while your other half has that steer axle wheel cranked all the way and begins to roll. Nobody ever lifts the steer axle to reduce the scrubbing.
-
Presumably from the Drive axle wanting to push the coach in a forward direction still. Anyone for ”fiddle brakes’ on their Prevost?
-
I pull trailer all the time I never lift tag can not turn that sharp with trailer on , I run 110 in front and 100 on drives and tag never a problem , I change tires about every two years because of miles never have had a blow out in 30 years and tires wear even all of them I get my coach aligned every two years unless it needs it sooner when I put new tires on

125 all around!

Peter,
How many miles are you driving a year that requires your tires to be replaced?
