Title: Is this a reversed tag axle rim?
Post by: Scott & Heather on February 24, 2016, 05:12:51 PM
Is this an MCI with the deep dish side of the rim facing out on the tag axle?

It's offset from the drive axle- a super single?

Yep you see that I did the same on my MCI 8 and it ate tag axle tires up in a hurry but looked good

What size of rim and offset would that be. Is there any chance of more pictures? Thanks for now

As Clifford said, it may look good, but eats up tires. That's because the offset of the wheel throws off the alignment of the tire. And you put undue stress on the outer wheel bearing.
When we first came out with the super singles, the wheel manufacturers simply made a 14" wide wheel that was offset to the outside by 2". Freightliner quickly found out that put undue stress on the outer wheel bearing and for those truckers that are at maximum gross weight all the time, made for wheel bearing failure. Now the only way you can get super singles is with a mid width axle that allows the super single wheel to have a zero offset. You can still convert it back to duals, it's just that the duals will be out to 102" now with the wider axle. Good Luck, TomC

The tag on the D is only inset 1 inch from the outside dual I am thinking about moving it out flush with rear dual since it has a follow along tag I don't believe tire wear would be a problem, then again it could be I am finding out the people that design the buses knew what they were doing most of the time

as noted, tag axles and their tires have been carefully positioned for the suspension to do its job, both for turning forces and straight ahead stability.

Best to focus on other areas of customization?

happy coaching!

My Newell came with the tag dished in so that it looks like the drive axle outer wheel. It is about 1 inch inset. No problems or concerns over tire wear.

All the  RV manufactures turn the dish out on the tag, Newell with the monsters they are building now turn the dish in on the later models just like the buses

Wonder what Bluebird used.All of their tags were turned in .I never really looked at one up close but I am fairly certain that the tag ran in perfect alignment with the outer tire on the drive wheel.

Course the best is the MCI cargo or the GM PD4501 with true tandem duals. I don't think I'll get stuck as easy as a bus since my truck both has tandem duals and dual drive with lockup. Good Luck, TomC

The addition of slides, granite, & marble have pushed the weights up so high that the highest capacity axles are being loaded to maximum capacity.
Also, when the tag rim is dished in like the steer, there is more room for things under the coach.

Mine weighs 36000# full of fuel, I've seen where some of the new ones are twice that.

Pretty sure 55,000 is max for 3 axles

The new Newells are rated at 63,300 GVW we have a friend that owns 1 and I love the Porsche dash in the Newells it's something else

     Wow.  After I stripped my bus, it was just above 17K pounds.  All fluids full except fuel - that was about 1/4 full.  Of course, being a transit, "stripping" it including taking out about 1000 pounds of bubble gum.

I could not believe the IH 45 Foretravel was 54,000# GVW with a 600 hp Cummins engine either
Title: Re: Is this a reversed tag axle rim?

63,300 would be gross combination.  Even on a tandem semi, you can't exceed 34,000 on the tandems and usually 12,00 on the steer axle.  With most buses or trucks with non dual tag axles, they weigh the rear axles separately and you can't get to 34,000 pounds.

Can you imagine driving your car and getting rear ended by  a 64,000 lb coach??

So would the gross weight be less than 55,000 for a 3 axle? 46,000?

I should know these weights but I forget, I know in California we get nailed for a few hundred over 80,000 on 5 axles at the Oceanside SB weigh station.

I bet TomC would know

Check it out here is Newell's numbers

20,000# front axle
28,600# drive axle
16,000# tag axle

The H series Prevost Vip are 58,000 lbs GVW now  

There are no DOT regulations on RV's I guess the states could nail you though

My DL3 is 50,000 GVW

Did not know that Clifford, just automatically thought RV's axle weights would be same as DOT regulated semi's. Good to know, thanks

I don't want rear ended by a 30,000 lb bus  ;D

Lol. True. Give it time, DOT will start managing rvs

They don't require rv's to cross a scale, however, if anything happens and they weigh you, you're still limited by published axle weights.

In California they have been known to check people coming in and out of the dune areas.

The bad boy Prevost and Newells have a 20,000# trailer hitch also,there is a loop hole somewhere for RV's

I've heard of people getting turned back going into Florida for overweight on the steer axle.  That was on a racing website, and typically those toter-home RV/semi tractor deals.
