Re: Tire pressure Reply #50 – September 12, 2015, 07:14:51 am Pierce, I run Michelin Super singles on my semi. I get about 259k out of them treadwise. Out of about 9 Virgin casings I have sent in for recapping 1 has actually passed their test and been capped all other casings were rejected. the one I had capped lasted 38,000 miles when it let go. So after a after hrs service call,$250.00 and the new tire 956.00 plus the cost of the failed retread 450.00 I should have bought a new Virgin. All I run is Virgins anymore I sell the casings to the tire shop,, Most of my issues are sidewalls blowing out. If something penetrates the tire casing,and is not discovered or it exits. the penetration will let the air pressure inside the tire go in between the belts and separate them usually forming a bulge in the sidewall. Then boom it lets go. It is really important to inspect tires for nails etc and remove them. If they do penetrate the tire casing it needs to be repaired from the inside with a plug patch. this type of repair will keep the air inside the tire.I also carry a plug kit with me but after using a plug to get going again I have the tire repaired with a plug patch soon after.

Re: Tire pressure Reply #52 – September 12, 2015, 10:47:01 am Quote from: Chuck & Jeannie – September 12, 2015, 07:43:12 amHow long will that little tank run a 1" impact wrench?I only use "Big Bertha" on stubborn lugs and in fact, have not had to use it at all on our U300. The tank is almost always connected to a compressor supply hose and the bigger hose is used to cut the friction loss so the big gun will run at full power. Your probably noticed the tank has 3 female fittings. I use a double male to allow air into the tank from the supply line or to charge it if I want to carry the tank to another location. Since I always keep a coating of anti seize on the threads, I only torque to a little less than 300 lbs so any decent half inch air gun will take the nuts off very quickly. If I ever win the lottery, I will buy a little Milwaukee electric impact. They will take almost anything off.Stump, yes, inspection will catch a bulge where air has gotten past the belts and is just waiting to pop the side. YouTube has some sidewall blowouts. I have had some big ones on my tractor rear tires. Even at 22 psi, they make a huge noise. Bridgestone says rubbing against curbs can cause damage aside from pot holes. Also, that under inflation is the cause of many of the "road gators" we see on the highway.Tubeless plug kits are really good to carry and should (have not tried a plug yet) work on an airbag with a normal leak. When my airbag failed, it could have been easily fixed with a plug. As it turned out, I was able to drive it home and fix it.Pierce Quote Selected
Re: Tire pressure Reply #53 – October 08, 2015, 11:26:37 pm So I finally got an opportunity to weigh all 4 corners of our coach (Oregon scales are always open and free) and its full of diesel, propane and almost full of fresh water. All holding tanks empty. Heavy front was 4300 and heavy rear was 8800. Actually rear was same within 50. According to the Michelin site the 275/80 r 22.5 xze tire chart for weight doesn't even go that low. Starts at a couple hundred pounds heavier. The pressure for front and rear would come in at 75 lbs. Does anybody else run that low of tire pressure. I haven't seen that pressure posted. Let me know before I start letting air out. Checked the tread depth with gage a few weeks ago and running about 2/32 more ware in center at 85lbs single and 90lbs dual. Tires are 3 years old and 19/32 average. Quote Selected
Re: Tire pressure Reply #54 – October 09, 2015, 05:28:19 am I would not run less than the recommended tire pressure on the I.D. plate, should be 85 single and 90 dual. When I installed new Michelin tires two months ago (same size LRH ) the tire shop wouldn't put less than 95psi and said that was the minimum they felt comfortable with in that size and H rating tire. I have not had the opportunity to weigh the coach, so I have left the pressure at 95, though I feel I will probably lower the pressure a little after I know my actual weight. Quote Selected

Just be aware that the "recommended tire pressure on the I.D. plate" is based on each axle being loaded to its GAWR. So, if you are near your axle ratings, that recommended PSI is very close.But, if you are well under that weight ....... Quote Selected
Re: Tire pressure Reply #56 – October 09, 2015, 11:29:43 am True ..... But, when you don't know your exact weight it is better to err on the high side rather than run overloaded and under inflated tires. Quote Selected

Until you weigh, better to over than under inflate.But, of course best answer is to weigh it and get it right! Quote Selected
Re: Tire pressure Reply #58 – October 09, 2015, 11:38:04 am In Bob''s case ..... His weight is below the minimum on the Michelin tire press chart. What then? How low can you go without being below the minimum safe inflation of the tire? Quote Selected
Re: Tire pressure Reply #59 – October 09, 2015, 11:39:11 am Do not go below minimum-- and that is what the tire charts say.Said another way, minimum is minimum. Quote Selected
Re: Tire pressure Reply #61 – October 09, 2015, 12:18:29 pm Thanks to all for the feedback. Weight on id tag for front is 10,000. I'm at 8200. And tag says 19,000 rear. I'm at 17,200 rear. At least I won't be going with the max pressure on the tire at 110. I know that I won't be wearing the tires out either way. (Gonna try though) Just interested in getting the best handling and best ride possible. Looks like with 5lbs cushion I'll go with 80lbs. Quote Selected
