Different Tire Question

[denochs]

Just received 6 new tires for the rear tandem & tag axle I ordered from a wholesaler thru my friends trucking business. I personally went thru the ordering process with the guy on the phone and ask for 11R 22.5 16 ply. To make a long story short, he shipped 14 ply tires. Before getting into a dispute with the guy I wanted to know from those of you that have experience with this if the total Gross Weight Capacity of the tires exceeds my coach Gross Weight Capacity am I going to be okay with the 14 ply tires. If you're interested to know the tires he shipped are rated at 6040 lbs each. That totals just over 36K. The front tires are 16 ply and are rated at 6610 lbs each. So, total weight, that is over 49K. The rig is only rated at 44K

When I call the company Monday, I really need to know where I stand first. If I should not use them then we need to work out a way of getting them exchanged. After all, I realize it is his word against mine in the final analysis. And that's what I get for doing business over the phone to get a good deal on tires. If it's okay to use them, I want the satisfaction of raking him over the coals without having to worry about him not working with me.

It's an issue of weight. Have you weighed your coach? I bet that it's almost at the GVWR. Your coach probably left the factory with code H tires (16 ply). I don't think Code G (14 ply) would even be safe to install, because your coach weighs more than the tire is capable of carrying at maximum inflated pressure. Plus, riding at maximum inflated pressure makes for rough ride. Better to have a heavier tire, able to lower pressure a little for softer ride.

You ordered 16 ply, I'd insist on 16 ply. Besides, there is the weight issue.

Jim,

Thanks for your input. I'll go to a truck stop on I 85 very near here and weigh the coach first. And you're right, the coach came from the factory with H rated tires. So, other than weight, do you (or anyone else on this forum) see any other issues that would prevent me from using them IF for some reason we cannot remedy the situation? I agree with Ken. And hopefully he will offer to immediately send the correct tires. If I can be sure of the safety factor, its not worth getting into a pissing contest and getting upset to the point of my blood pressure going thru the roof. When I retired I left all that stress behind and will stand toe to toe only when someone is taking advantage of me or endangers me and my family. I believe it was an honest mistake.

Your Code G tires (14 ply) tires are rated 6040 lb @ maximum allowed pressure as written on the sidewall.

My coach has a 10,000 lb front axle, which means each tire must be rated for a minimum weight of 5,000 lb. Your tires should be fine for my coach, allowing for a generous safety factor for unforeseen overweight conditions.

I think if you look at your weight figures, you'll realize the tires you received will not work for your coach at all. They would be drastically overweighted before you put anything in your coach at all.

I don't think you can consider using them at all.

I agree with Ken, you ordered load range H, 16 ply tires, not load range G, 14 ply. What may be a good bargain for H's is probably not so good of deal on G's. I the factory put H's on your coach, I certainly wouldn't go less.

The way I figure it there is a total tire capacity of 49,460 lbs. on a 44,000 lb GVW machine. What's wrong with that other than "tires not as ordered"????
We all did pay attention to the six tires on the rear of this coach????

[jimkate]

The total maximum weight of those tires may add up to more than the GVWR of the coach, but with most DP tag axle coaches, the front axle is usually around 12,000 to 14,000 lb. That nixes the use of Code G tires.

You'd have to weigh each axle to really know if the Code G tires are safe on this coach.

[Tom and Patty]

He has 16 ply on the front. I would only feel comfortable if you knew the left and right side weight of each rear axle. That will answer your question and leave no doubt as to the use of the 14 ply rated tires (G).

[Gary RVRoamer]

If your coach has only 6 tires, then the LR G is not sufficient for the GVWR (and probably not for the actual weight either).

If you have tag axle and therefore 8 tires instead of 6, you may be ok, but not for sure. Typically the tag will carry an extra 10k lbs of so and the rear axle 20k lbs, so the rear would be ok at 30k on 6 tires. But the front axle is probably rated at 12,600 or 14.6k. Those G tires are barely ok at 12.6k, but way short at 14.6k.

My 2004 American Tradition has a 14.6K front axle and requires H rated tires. Yours probably does too.

I am buying a 2000 american eagle that has dry rot cracks in the michelin front tires. How much does the rig weigh and what type and size should I get. I Augusta, ga, where should I get them? thanks for any help.

We have a similar coach, a 1999 42' Monaco Executive w/tag. It goes across the scales at 35,600#. Its GVWR is 45,000#s. It can tow another 10,000#s.

It has 14 ply - G rated Bridgestone 295-75x22.5 tires at all positions and has since new.

The front axle is rated for 12,000#s. Its actual weight is 11,600#. The tires can handle 12,350#s max.

The drive axle is rated for 23,000#s. Its actual wt. is 17,000#. The tires can handle 24,700#s max.

The tag axle is rated for 10,000#s. Its actual wt. is 7000#. The tires can handle 12,350#s max.

When I put new tires on it, I might put H rated tires on the front axle only, the rest will get G tires.

Good Luck

Hal, my thought process is along those lines too. That doesn't mean we are right. Hopefully, when I call the wholesaler this morning he will say send them back and we'll pay all the shipping.

BTW, I did put new 16 ply tires on the front axle last year.

I thought this would be a good discussion for those of us that don't know what other issues there are other than weight.

One thing I will do as a result of this experience is have the coach weighed on each corner as has been suggested on other threads.

Don, just curious, if I'm stuck with these tires, how many miles have you put on your Monoco Executive??

Thanks for everyones responses. I'll post again after I talk to the wholesaler this morning.
