Tireman9

Hello Tireman. Need your advice, please. Have Michelin 255/80R 22.5 XRV tires, 49K miles, DOT0315. (installed May 2015) Minor sidewall cracks less than 4 inches long, 8/32nds tire tread.
Local dealers (Phoenix, AZ) don't seem to have any, want to sell me different brands/sizes. I'm not sure of different size applicability. Any advice on continued service/different brand and size? I'm happy with Michelins - have owned several sets since 1998.

Hi Tireman9 I made a post on the board about a tire failure, no tire could be found and no towing company could tow us to our campground 7 miles away. One tire company that coach met had contacted call and said he could move one ot the dually tires to the front so we could get off the Hwy 93 after sitting for 10 hrs. Members on the board said that the overload on the tire would damage the tire and needed to be replaced. Would traveling 7 miles at 55 mph cause damage to the tire that it needed to be replaced right away? the reason for the tow to campground it was closer to us than any truck stop or tire replacement company.

What do you think was the cause of this tire failure?

Hi Tireman9.
I have been reading lots of threads on tire pressure. I am still confused. 2020 Winnebago Adventurer with 235/80R22.5 tires.
I have the Micheline chart but even after calling Micheline I am not sure what tire pressure to use.
The vehchile sticker says 90 psi on all tires. I have weighed the RV as follows: 6,860 lbs front axle and 13,780 lbs rear.
Micheline says to set pressures using individual "wheel" weight, not axle weight. I have no way to get the wheel weights.
Here is a question that Micheline would "not" answer: do I dived the axle weight by 2 to get wheel weights? I don't think so; the numbers just don't jive with the tire pressure chart.
I have excessive outer wear (both inside & outside treads) on both front tires, telling me they are under inflated at 90 psi. So I now run them at 95 psi. But I cannot logically see this presure justified on the tire pressure chart for the weights I have.
Your comments appreciated...!!!!

Hello Tireman9,
I'm sending this photo to you for a friend of mine. He owns a 2019 Newmar Essex on a Spartan chassis. The photo below is from the passenger side tag axle tire, 315 80R22.5 XZA. The wear pattern in the photo doesn't go the full circumference but about 180 of the 360 degrees. The tire has 40000 miles on it. The other tag tire doesn't have this wear pattern. He runs 85 psi in the tag tires based on actual coach weight on the tag axle/Michelin tire pressure table. Your assessment and professional opinion would be appreciated. I'm not sure if I created the URL for the photo correctly. Thanks in advance for any help you can provide.

Hello Roger, you may find this tire thread quite interesting: https://www.irv2.com/forums/f84/norma...ml#post4974761

Roger, I know from your blog that you have and favor Tire Traker TT5500. I have narrowed my shopping list to either the TT-5500 or the Eez Tire. It appears from the various reviews that these have similar characteristics (warranty not included) except that the TT display is portrait orientation while the EEZ is landscape. The landscape orientation appears to give the EEZ a larger font display, which to me is a plus. What am I missing? Truly value your opinion.

Roger - saw that you plan on being at the FMCA Perry convention in 2016. We are having a Safari International pre-rally in Hoboken GA the week prior and I am looking for someone who can weigh our coaches (~35) at our rally. Do you know anyone that I might contact?

The axle system on RV trailes are designed to be the weakest link. As you well know tires are not static items. That is to say their strength is in the pressure they hold. Therefore putting tires with a larger load capacity than the axle load capacity is a small insurance factor and with the RV trailer axles is prooving to be a much needed factor because of the dynamics of the moving trailer.
