if you decide to do that change i'd be curious to see weigh slips before and after. in theory, wouldn't the axle with the taller tires carry more of a load?
I would think you would want the same tire on the Tag axle as the drive axle
The narrow tire would have more pounds per square inch than the wider tire !
I do not see that the small difference would be significant in all reality on the bearings or the integrity of the Tag axle.
Driving Habits and HUB, Bearing maintenance, Tire rotation and tire air pressure, ALL easy to ignore ??? along with the weight management of the coach is by far more critical than any thing else !!
((( I try to ) IF Possible ???
1. Never drive with any fluid in the Holding tanks !!!
2. very little water, Use bottled while traveling!! in the fresh water tank
3. and per this forum I am removing the Spare ! Tuesday ! Before we take the Coach to Florida.
4. With the abundant supply of Wall marts-K-marts and groceries, Restaurant we try not to Load up on supply's. especially if we stay in the parking lot every 3-5 days we get to stock up with 3-5 days of Goods!!!
We use a dish soap bottle to flush with...just squeeze, and it's actually better than the sprayer, and uses less water...we also carry bottled water, and a couple of empty gallon jugs to use for wash and refill of the soap bottle...small thoughts, perhaps, but better than traveling with any full tank, except for gas...always gotta be thinking...BTW, 1/2 to 1 cup of Dawn and a couple of gallons of water in the black water tank just before taking off on a trip will clean it out really well...mike

Hello Don, I think the issue is where the spare is placed as much as anything !
Hanging onto the far rear behind the rear axle creates a negative leveraging action compared to the same weight over the axle or mounted in a forward position.
I have no idea how much the spare and steel wheel weighs but over 100 lbs I would think ??? I am sure some one knows !!
Ya know, if I have a flat, I've got a lug nut wrench, but I'm not sure why I carry it(except it's a TOOL)...I also carry a cell phone and a Good Sam ERS card, and tow a car that may be (ok, IS) cosmetically challenged, but so far runs really well...mike

Water in tank?
I heard/read somewhere that you should have the water tank full. The weight of the water puts more weight on the rear taking weight off the front end and the front need all the weight off it you can.
Spare, jack, wrench ?
I have changed a flat. Sometimes the phone don't work, sometimes the toad isn't there.
Tires?
I replaced four with: 8R19.5 load range 'F' Power King U.S. made radials. Soon after I had a blowout (see above). I then replaced the other four with 8R19.5 Hankook Korean made tires. Didn't have any American made. Only other tire was made in China.

Our toad IS another spare...we don't drive the unit without the toad, and when we park for any length of time we PARK...then the toad is the primary vehicle...don't carry a jack...extra weight, and I'm not gonna use it...the lug wrench is therefore superfluous, but it makes for an interesting horseshoe stake...m
Well, we carry a small jack, wrench, and spare for the toad...

I guess it's, 'Want ever trips your trigger.'
When I pull out of the driveway the 'Silver Bullet' is locked and loaded with a full tank of water/propane/gas, and every spare I think she may need from a set of belts up front to a spare air compressor just in front of the spare tire in the very back. Plus all the tools I may need.
I sometimes go places ahead of the wife and the toad and the wife sometimes has other things to do before I've finished the mission I'm committed to. Which means, NO toad!
I've gone though the, "Call road service." Plan on the day, if you start in the wee hours of the morning. Otherwise, can you say overnight? . Been there, done that. Got the bill to prove it.
Just another level of insurance.
Which reminds me, I used the spare the Holley gas pump and filter, need to buy new ones.

Hiya Mel,
I'll try this post, again, as the last one disappeared...???
I carry a lot of tools, including a 50 foot airhose with several attachments. I carry spares... fuel pump, belt, hoses, fuel filters, fuel line, and a list of part numbers...and, yes, the spare tire...it's in case whomever changes a flat doesn't have that particular tire available. My wife is unable to drive, so I don't have your luxury of two drivers. I have a bad back, and feel that the cost of waiting on the side of the road or paying for a motel far outweighs the cost of a visit to the ER...what tools do you carry?

Least it you have what you need, a Good Samaritan will come to you aid when you least expect it. But without the parts and your guidance you are at the mercy of the tow truck.
I have a thread here of my encounter of helplessness in the heart of Ft. Worth one cold rainy morning when all my batteries shorted to ground.
mel
We are currently in a motel in Durango, Colorado, since the battery thing happened to us 4 miles into our journey to the T2Q3 rally...sitting dead in the water, blocking the southbound lane of 550...almost dark, then...got dark quick...me and my trusty flashlight waving at traffic....sat there for 4 hours(22Degrees with a brisk wind)...so, we should get it back tomorrow...apparently, it had something to do with the distributor...luckily, the two back batteries were ok...
Isn't it amazing how this started with tires
