Toyo 295/75-22.5 tire pressure

Hello All, I've tried to do a search for this but the results are all over the board except for the answer i want. I want to check air pressure on my tires and add if necessary. Do I go off of what the tire specifies? and how long does a tire typically last, it seems that rvers use dates rather then wear as the barometer for getting new tires.

thanks...Fred

You need to weigh your rig "each axle" for a proper answer. Michelin website clearly states 10 years Max if no cracks or other signs of deterioration.

You can find the weight chart for your particular tires online. Weigh your coach, add 5 to 10 percent, look up the weights in the weight table and set your tire pressures accordingly.

For my 2005 Mountain Aire DP 4032 running Bridgestone tires, I run105 in the fronts and 95 in the fronts

Hi Fred,


You are correct, tire information is all over the map. In a nutshell this link gives you everything you need for Michelin. If you have another brand go to that manufacturer and get their chart. More importantly, this doc gives you the background info.


https://michelinb2b.com/wps/b2bcontent/PDF/RV_Tires_Brochure.pdf


Corner weigh your coach loaded with fuel, water (that you typically carry) & gear. If you haul a load of people, account for that. Use the heaviest corner weight for inflation lookup on the chart for each axle. If one side is much heavier than the other try to rearrange items.


As for tires, they usually age out before they wear out. This varies somewhat depending upon how well the tires are treated and how long they are exposed to the elements (uv rays) etc.


A coach that is stored indoors will have less exposure and should last longer. 5-7 years is a good rule of thumb.


Good luck,


John

Many of us Newmar owners would suggest replacing your tires after 6 years based on the date code of the tire. After 275K miles of travel from Alaska and every other state and having 2 blow outs it just doesn't make sense to go 10 years. Michelin says after 5 years to dismount the tires every year to inspect the inside of the tire which is a big job. With a front tire blowout on our Essex returning to lower 48 at over 20K dollars damage and not having the coach for 4 months with 6 year old tires makes us well aware of the importance of our coach tires.

We have the Toyo 295/75 R22.5 tires and a similar coach. I have weighed ours when loaded for travel. Currently run 94 on the front and 80 on rear. I called Toyo and they were very helpful and they sent me a chart. The proper pressure improved the ride and handling. Also had the wheels aligned.

where would you go to get your wheels aligned?

I had ours done at Cowser tire in Fort Worth. They are a large truck tire dealer.

Not sure if you are near Spartan, they would be a great choice. We had ours done at Freightliner in Gaffney. Important to check ride height and tire pressure prior to alignment

I can tell you from experience don't ignore the date code. I am a firm believer in the 6 year rule.
