Wheel bolts

[Gripster]

2025 Revel Sport
I was surprised to find the 2025 Revel Sport, with the Revel alloy wheels, has only 5 turns of thread engagement for hand tight (maybe 6 turns at full torque). For the 1.5mm pitch, this is only 7.5mm thread engagement, equating to only about 1/2 of the 14.5mm bolt diameter.

This model year has a steel spare wheel, but no additional wheel bolts for the steel wheel (I checked both jack and tool locations). The supplied bolts have 32mm length beneath the spherical head so this would stick out past the steel wheel by nearly 32mm (as stated by someone above).

My conclusion seems to be that WB decided that 5-6 turns was enough for the alloy wheels and this same 32mm bolt length is also suitable for the spare steel wheel. This doesn't sit well with me as I would like to have at least one full diameter of thread engagement. It seems I am looking for a 40mm length bolt and not sure if the 58mm will be too long as cautioned by this sticky.

Don't assume this is intentional. They might have changed wheels and not even thought about the bolts. A friend used to say ineptitude is universally dispersed. What does the hub look like? I don't have a 2025. I'd expect to at least go through the hub if there is room behind and it's fully threaded.

Good thing he checked! I'd be getting longer bolts also.

Front bolt can definitely be decently longer. But the rear not , because it will go in to the handbrake pats.
I have a 5mm space to clear the strut. So I use 2 size wheel bolts for my warlords rims

> I would like to have at least one full diameter of thread engagement.
This is not possible because the hub plat is not thick enough for that.
I think it is about 10 to 12 mm thick (did not measure it )

Wheels can vary significantly across styles and manufacturers, but I agree 1 full diameter of thread engagement seems like a reasonable minimum req'mt for lug bolts. See attached picture of lug bolt engagement on my 2021 Jayco Terrain.

Hey Guys! In post #61, I posted that my 2025 Revel Sport has only 5 threads of engagement so I have been looking to purchase a longer lug bolt to test for possible interference before I make the big purchase of all lug bolts. My searching suggested that MB part 000-990-24 -07, would be 58mm long so I went to my local dealer and purchased this part but to my surprise it is only approx. 33mm long (same as my existing bolt).

Has anyone purchased this part and found it to be 58mm long? Various sites describe it as 58mm and maybe my local dealer just has some mixed up inventory.

Any other part # that is longer than 33mm but shorter than 58mm with the MB spherical head? I am really only looking to get one full diameter engagement so need perhaps 42mm lug bolt.

A0009902407 is quite a bit longer, but not threaded the whole way. The dimensions in EPC aren't exactly helpful.

Guys
Please don't let this happen to you!

Basically a 2006 TIN owner and family driving their motor home and trailer rig to the Denver area.
Somewhere en route in Wyoming, metal road debris flew out from under a semi and tore through the side wall of his rear tire, mounted on a factory alum wheel.

Apart for the pucker factor to keep it straight and upright and stop at about 70mph (OMG)
He got the thing to the side of the road!
OK--now fit the spare--a steel wheel!!!

Forgetting the wheel bolts are LONGER for Alum wheel he bolts up the spare--then carries on!!
Well for a few feet!

In short, (excuse the pun!) the longer wheel bolts tore up the parking brake shoes, hardware, park brake cable, ABS tone ring, axle bearing carrier and ABS sensor. A right bloody mess.

Poor fellow limped it into our shop yesterday.
I managed to get enough stuff to fix it, the local Dodge dealer had some parts, and I had I did, the rest on the shelf. (luckily)
The Dodge parts guys asked if I had tried the local Benz dealers---Big chuckle--I stated they aren't even open on a Saturday gimme a break!
I should go work for them said Mitch the parts guy!

Anyway a few hours later they were motoring away "All ship shape and Bristol Fashion" but short of some holiday money. Tires for starters aren't cheap in commercial 10ply that was $420 before we got going! And he had just replaced them all round.

Anyway bon voyage and lets hope he has no more incidences going back home.
AND
Don't forget you need shorter wheel bolts with "steelies"
Dennis

That tire would have been practically free had he purchased it from Discount Tire, road hazard warranty are $25 or less per tire.

@Gripster those bolts you pictured look like regular MB wheel bolts for steel wheels. Alloy wheels usually have a different taper and use bolts like these. My Revel with the old Methods had them.

Better not let Mr. Impact gun near it.

Hey Gripster,

Gorilla makes a 45mm lug bolt in the ball seat (round/sphere). Here is the part#
Part#18024 BOLT BALL R14 17MM 14-1.50 CHR 45MM

I see you live in SoCal, so if you need help getting these let me know I'll point you to a dealer that can order them near you

Is the confusion that some listings are measuring the threaded length, but others are measuring the full length from the tip to the top of the bolt head?????

Hey this is awesome and thank you for the reply. I have been slowly sitting on this problem with the excuse that jacking up the sprinter in the street (instead of my garage like I would normally do for working on my cars) is inconvenient. I did purchase qty 1 bolt from Europarts of the longer OEM so I could get a better understanding of what is too long, or not. Part Number: 906 990 00 07

Anyhow, with your Gorilla link I am now looking to confirm Mercedes is using R14 radius instead of say R13. I had not really thought of this until your post with Gorilla and how searching for this now I do find other alternatives out there. I have never had a vehicle with radius style lug bolts (not to mention bolts vs nuts).

Does our Sprinter OEM use R14 radius head profile? I did confirm that my wheels on the 2025 Sport have a radius and not conical seat. Maybe I should get some Sillyputty and take an impression of the OEM bolt I purchased and find what radius washers looks like it fits

So most manufacturer specifications are using too many are making it too complicated thus confusing majority of the end users.
Currently the Stock Mercedes oem wheels run an R14 Seat

To make it simple, our van wheels use either a Ball Seat (radius/rounded) or Conical seat (acorn/60 degree angle), depending on what wheel manufacturer it is. Stock Mercedes primarily uses the R14 Ball seat, R13 is used for more less duty vehicles (passenger cars and stuff), and majority of Aftermarket wheels (Black Rhino, Method, Reika, etc) use Conical seat.
But its always good to double check, look at your current lug bolt and see if its an angled or round seat.

@vreihen Gorilla Lug bolts always use the thread length when using the numbers. For Mercedes, they make 3 different sizes:
27mm-for their cars
32mm-for vans with aftermarket apps
45mm-when needing longer bolts for certain situations like using spacers, etc.

the easiest way to get the proper length is just to put a stick, straw, or something straight in the lug hole, mark where the lug hole begins, and measure in millimeters. Then choose the closest bolt length to that number.

Hope this helps.

FWIW, the MB web parts system shows this part number as the factory lug bolts for alloy rims, and the 000-990-24-07 part number as the steel rim lug bolts.....
