Most major truck tire repair shops have a mobile tire truck, and they will repair or replace on site. I would call first as you might need to make sure if they have a proper sized tire available, in case they cannot fix.

ps: Note, pumping up these large high-pressure tires on-site can be a bit rough. I am a dealer for PowerTank (www.powertank.com). They make a great RV package, which includes a high-pressure C02 tank, adjustable regularor and air tools, which can fill up a tire very quickly. I’ve tried pumping using my on-board compressor, but even with a air doubler it can be a hard go. If you’re interested let me know, and I can get you better than internet pricing on a unit.

Chris,

Like Ray said, any truck tire dealer with mobile service can fix you up. If you ran it flat, it’s toast, but if you picked something up on the road and it went flat while you were sitting, they maybe can salvage it. They should bring a new tire with the service truck, that way you’re covered. The tire change/repair can be done on site.

For a referral, call Parliament and ask who they use. I used their mobile guy one time, but don’t remember the name.

AAA will come out and fix it if you have AAA rv .. It is probly an easy fix if it still has 8lbs in it could be the valve core ,, I would just try to see if it would just blow back up than spray with some water and dish soap in a spray bottle to see if you can see the leak it could be gone if it was the valve core make sure you keep caps on them and be careful of extentions they are trouble. Some times you need to drive the good tire up on a 2×6 or something to lift the low tire so it may be able to seat well

Chris,

Many tire shops are not going to have your tire make and size. Although TCI-Tampa is not high on my list, they will have your tire and, I think, do road side service. If you need a tire and have the time, go to TCI-Tampa and pick up the tire under the FMCA purchase program and have it available for the road side service guy.

Thanks for the replies. It has gone flat sometime since last Friday when I drove it onto the property. It has not been driven under inflated. It is the outer port side drive tire (no valve stem extension) and has an inflate-through double seal valve cap. I have an external compressor that I keep on the bus and I put about 40PSI back in the tire. I soap sprayed the valvle stem and cap and it is not leaking. No audible leak, but I have yet to start and raise the bus to travel height. I am going to re-check the PSI in the morning. I am hoping it can be repaired, but thanks for the heads up Gil in making sure I use somebody that stocks the Michelin replacement tire.

We have Good Sams and not AAA for roadside. Does anybody know if it is worth calling Good Sams on this? I was not aware that AAA would cover the repair (if repairable). My understanding is either service will cover the service call but not the repair or replacement.

For your own safety make absolutely certain that you know for sure it was not driven on when underinflated. A tire can lose a lot of pressure and still appear OK. The problem is all manufacturers will point out if a tire is run at 80% or less of its required pressure it needs to be scrapped. If your drives require 85 PSI for example then any pressure lower than 68 PSI makes the tire a flower planter.

[gary]

Jon I hear your warning. The problem is I could never know if it was driven under 80%. I checked all tires as i always do before moving the bus a week ago Friday. I drove the bus approximately 50 miles that day and parked it where it sits now about 6 hours later. Nothing obvious until I saw the 8lbs yesterday.

I put 85 lbs in it around 10AM this morning and it now reads 86. Not sure of the rate of the leak as we gained 50 degrees today with the sun.

Tomorrow AM will be a good indicator of the leak rate.

I can only estimate that it was not driven under inflated during our 6 hours last week but how would one know?

[Christopher]

I know I know another reason for pressure pro…..

Might be a good time for you to learn a little about your tires. Do a little research on internet about date codes (how old your tires are). Also tire matching. Don’t be a victim of a salesman. Ask questions. A honest tire guy will answer your questions. If you tires are original to coach; no matter how good they look they are done at 13 years. Last 4 numbers = week and yr of mfg. Ask ??? Bob

[Tom]

They’re toast a long time before 13 years. I believe Michelin says 5-7. I lost a 4 year old.

Lot of factors there: not time for that discussion. You are correct after 5-7 years time to start being cautious. (watch for signs). Maybe someone can write a tire article for the article section. My point being a near flat or even flat tire doesn’t mean a automatic new tire. Also on drive the 3/4 inch matching circumfrance is important when matching a 318 80 -r 22.5—-source Prevost Maintance manual under tire matching. Bob

Tires were all installed new in early 2012 with all mid to late week 2011 date codes. They are at best 1.5 years old and installed less than 1 year ago. They have about 2000 miles on them as the bus was not driven more than a couple hundred miles since the install. We purchased the bus in August of 2012. I have no concern with the age or condition of the tires. I will not be replacing the set for another four-five years or so.

The tire reads 83 lbs. this morning at around 9AM and 55 degrees. Not really sure what’s going on with it. I am beginning to think I may be the victim of sabotage by some kid jumping my fence and letting the air out of the tire. Can not explain how else it lost almost all of its air yet is holding now after I simply pumped it back up in place. Going to check again tonight and tomorrow morning. I have an on-site tire service calling in the AM to schedule a time to come out on Monday (Olin Mott) and remove the wheel/tire and inspect it for a foreign object/damage/leak/valve stem/etc. I do not have the equipment to remove and inspect the tire myself. Always the possibility that something stuck in the tire, it started deflating then sealed pretty well around the object temporarily where it sits. If that is the case, then I am back to not knowing if I drove on it under inflated. I will wait and see what we find tomorrow.

If you had checked tire pressure prior to the loss of air pressure the answer could be as simple as the schrader valve not seating due to some foreign material lodged in it. When you re-inflated the tire you could have blown it off of the valve seat and cured the problem. It could just as easily been kids screwing with you. If you are comfortable ruling out any driving on an underinflated tire don’t worry about it and just keep an eye on all tire pressures.

[Archived]

If you’re using Equal, the schrader valve would be the culprit as Jon pointed out.

[Ray]

I use inflate-through double seal valve stem caps all the way around. I was having the problem with a couple of my valve stems sticking open when checking pressure. These double seal caps had been working great without a single leak or loss of PSI on any tire over the last few months. Always possible that one leaked, but both the top and bottom seal would have to leak to lose air. Remote tire repair company I lined up (Olin Mott) never called today as promised to schedule the visit. Tire continues to hold 83.5 PSI this AM. It does not appear to be leaking at all. I still plan to have it removed and checked out thoroughly before putting any highway mileage on it.
