How about two new tires on the front (not that I think you need them), and now you could keep the old fronts for spares if the rig did not come with one. My guess would be that 90% or more of our so called BLOW OUTS are caused by slow leaks in a tire (nail/screw), as you drive down the road the tire slowly looses pressure which in turn causes the side wall to flex excessively , this generates a lot of heat, as the air pressure drops the flex goes up as does the heat. After a while the rubber inside the tire starts to disintegrate and literally starts crumbling under the flexing and the heat, ultimately with the inside of the tire falling apart as you drive, the side wall fails, boom, blow out. New tires fail the same way as old tires. I would say that tire air pressure monitoring (with a alarm) would be money better spent then throwing out almost new tires. JMHO

A good example of rubber deteriorating with age is to go to an office store and buy a bag of rubber bands and after about 6 or 7 years pull a new one out of your desk drawer and try to use it. I know first hand from my own blow out experience that tires do break down with age, and while I believe that proper tire pressure is critical and that TPMS is a good idea, tire age is a major contributor to blow outs.

Sorry if I chose the wrong words Mark, I did not mean to infer that you said that rubber does not deteriorate, I was merely using your post as a jumping off point to stress my point about the problem with tire age. While the rubber band analogy isn't perfect, they do crack and dry out much like the rubber in tires after time, especially with a lot of non-use.
 
Hope this works, can anyone recommend a tire pressure monitor system that can be added to a coach 22.5 tires?

Any of the TPMS can be used on 22.5" tires.  Many here recommend Pressure Pro.
 
We have Pressure Pro sensors on all motorhome tires (8 total) plus the toad tires.  We've already been glad to have PP because a toad tire got a puncture near Chatanooga and deflated almost instantly.  The audible alarm told us something was wrong and it took about 1/4 mile to pull off to the side of the freeway.  It was totally flat by then.  So get a TPMS as soon as you can.  They're worth every penny!

I also got a flat on my toad, I was moving from Colorado Springs to NY driving a rental truck towing my 1967 Ford Galaxie with brand new snow tires. By the time I saw the blue smoke in the mirror and pulled over it was too late to fix the flat. The tire looked like a hairy doughnut with one patch of tire tread (the size of your hand) hanging on the fabric. This is the great part, I brought the tire to a Goodyear dealer in NY and the dealer looked at the tire and measured the depth of the tread on the little patch of remaining rubber and called Goodyear support to get approval to replace the tire, they said OK give him a new tire no charge. Goodyear asked the dealer to save the tire so they could give it to their technical people, the dealer said he would put it in a envelope and leave it at the front desk. you had to be there but it was hilarious. Funny thing is I did not go to the dealer to get a warranty, just to buy a new tire.

This happened in 1974.
 
We were not as fortunate on a blowout on a Toad. In 1974 we were towing our Saturn behind an old MH when a Semi pulled alongside blowing his horn and pointing to the Toad. By the time I was able to stop along side I-79 in WV the damage to the Toad was $1200.63 plus the cost of a new tire. We now use the Tattle Tale on the Toad and TST TPMS on the coach. Well worth the money...... :)
 
I work on the Interstate (I-80) everyday and a lot of the time I am on road patrol, picking up dead animals and trash. Just today, I was picking up rubber off the road and shoulder for over a mile. Up ahead was a trailer with both passenger tires gone and the rims rounded off. The other two tires on the trailer were showing signs of age. Just today, I picked up seven tires that had blown. Four of them were semi tires. I have the Pressure Pro on my MH. They are good for a slow leak or if one of the duals goes down. If you hit a piece of steel in the road and have a blow out, know how to handle your rig. I do not have old tires. It just isn't worth it in my opinion.
 
"a trailer with both passenger tires gone and the rims rounded off"

Most of my rims are round, before I get flats! ::)

Loosing a tire on trailers with normal leaf spring configuration does not change the weight on the adjacent axle/ tire, so loosing one tire should not cause another tire to blow from overload, more likely the second tire ran over the object that the first tire hit.
 
I expect he's talking about the two tires on a set of duals, Mark, not on separate axles. Losing one puts twice the load on the remaining tire.
 
Just in case anyone is prone to buying safety equipment based on stastical data, here are some data:


leading causes of death:
Heart disease: 616,067
Cancer: 562,875
Stroke (cerebrovascular diseases): 135,952
Chronic lower respiratory diseases: 127,924
Accidents (unintentional injuries): 123,706
Alzheimer's disease: 74,632
Diabetes: 71,382
Influenza and Pneumonia: 52,717
Nephritis, nephrotic syndrome, and nephrosis: 46,448
Septicemia: 34,828

Death by Accidents:
All unintentional injury deaths
Number of deaths: 123,706

Unintentional falls: 22,631

Motor vehicle traffic deaths: 42,031

Unintentional poisoning deaths: 29,846


Motor Vehicle deaths

About 50% Alcohol related
About 25% Distractions like cell phones, GPS, maps, texting, eating, etc
About 25% other, like equipment, roads, TOD, type of road

brakes and tires are important, but... probably not the first priority for investments.

Easy ways to give yourself much higher odds:

take care of your heart, dodge the cancer bullets, dodge the stroke bullets, get a flu shot, use hand rails so you don't fall, watch what poisons you eat, turn off the cell phones when driving, don't drink alchohol when you might drive, do your maintenance regularly, stay awake, no speeding, etc.  Somewhere way down the list, is TPMS.

Just sayin' 
 
The only thing that proves is that statistics can be made to say what you want them to say....

Tao, it does put old tires and tire pressure in proper prospective. :eek:
 
All of that is irrelevant with respect to a TPMS.  A TPMS will, most often, catch a tire failure before it becomes catastrophic, and save you from significant damage or even an accident.  It won't prevent health problems :(

Maybe you can mount a sensor to monitor your blood pressure.
