Charles -

Take a look at my post 83972 (Re: Dual Tire Spacing). That was on my non tag 2000 Magna using Michelin tires. Best of luck with your decision.

Be careful if u go a size up from 315's, the rim size might change to 10" wide rims while your present rim are 8.25 or 9".

I use Continental 315's 0n my coach. with 8.25 inch rims with no problems. But coaches like mine with the C-12 engine and the heavier rear axle shared with Magnas, will not allow for enough clearence for 315 rear tires. Call Jim Cooley or Dave Remington at Oregon Motorcoach Center. or ask Paul at Les Schwab tire center in Junction City. They supplied the tires for CC and should be able to answer your Question.

I would look at Michelins chart for your specific tire and the weight on your axle and then add 10 lbs. Some Magnas could handle 24,000 lbs on the rear axle which would be 105 lbs according to the chart and then add 10 lbs would be 115 lbs. If you have a lighter carrying capacity just follow the chart and add 10 lbs. Of course the front is supposed to be set at 120 lbs no matter what. TWI 2004 42' Intrigue 11731

Couple of questions,

Where does add 10 lbs and front at 120 lbs no matter what come from ?

Never read those directions on the Michelin tire chart.

Hello, I have a 2000 CC Magna with 315's all the way around. The steer axle has 9" wheels and the drive axle has 8.25" wheels they fit just fine. However there's only about a 1/4" to 1/2" of space between the duals at 95psi. I've only had this coach for about 8 months and the previous owner had them put on in Junction city Oregon at Les Schwab. I'm also due for tires now as these were purchased in 2007.

Chip,

2000 CC Magna 5758

The 120 comes the fact that CC had tire failures on the front axle with owners under inflating their Toyo tires. The 10 lbs comes from experience and the accepted practices in the late 90's and 2000's when if you drove over or close to 70 mph the extra air in the tire promoted better cooling and less tire cord flex which generated more heat. Heat is the biggest enemy of a tire and when your driving in the Southwest on pavement where you can fry eggs and an overheated tire is your worst friend. TWI 2004 42' Intrigue 11731

I think I'll file your comments, weigh my coach and trust the Michelin charts.

Yup right tires with proper rating and use the chart with your actual weights.

The plus ten quoted often is an attempt to make allowance for the moving weights in our coaches.

I'm a believer and follower of the:
1) Buy the proper load range tire for you coach
2) Buy 6 months or younger tires, if you can
3) Four corner weight, and tire manufacture PSI settings
4) Plus 5 lbs (see my note below) or 10% extra PSI for reserve capacity, and minor air lost between checking.
5) Install Tire Monitors, and know what their PSI readings are n relation to your tire gauge read PSI. (They sensors can vary several PSI.)
6) Daily inspection of your tires with our rig watch around. Also walk around and check when stopping for breaks or fuel. (Look for cuts, bulges, or anything else that looks 'not right'.)
7) Before taking off in the AM, check your PSI on the tire monitor. Adjust for outside temps, and also if one side is baking in the sun. (You get a feel for this while doing it.
8) Age? I'm personally on a 5 1/2 - 6 1/2 age replacement cycle. From tire DOT, not inservice. Especially important for those that did not install the tires.
9) Extra careful inspections after harsh impacts. Say pot holes. And very careful monitoring for awhile and miles afterwards. As a bruised tire, can end up with a broken tire cord down the road.

The only thing that moves your forward, turns you, and stops you - are those little patches of tire contact on the pavement. I recommend cutting corners on wine, beer, elsewhere - to be sure you have the budget for the best tires you can buy for your coach. Don't cut corners on tires, IMO, as they are a critical safety item. Now, what is the best quality tire you can get? Opinions vary on this, and can become quite interesting as this topic seems to always have contray thinking:)!

Be safe, have fun,

Note: I only add +5 PSI to the tie manufactures chart. Because if my weights are in the top 25% of that from/to range on the chart, I pump up to the next line. So I have added contingency in my PSI. If not bumping up, the +10 is an easy number to remember:)!

I agree with your recommendations I always tell my friends, when you watch NASCAR and the Indy 500 they don't change engines but they do change tires Bob 06 intrigue 12047

Try Michelin XDN2, 12R. Look like snow tires, but not. They give you extra traction, no road noise, and if you ever camp at grassy campgrounds, you'll be glad you have them. Available on the FMCA discount plan. They are what firetrucks ðŸš' use on their drive wheels!
