B Class Aftermarket Rims "What worked for me and what to watch out for!"

[Guest desmo]

Hi All,

Since this thread is very quiet I thought I would liven it up a little with some fun I have been having with my newly acquired B Class.

There are a limited number of after market rims available to us B Class owners mainly due to the PCD 5H112 and Offset 49.

However after visiting rim and tyre dealers from Geylang to Serangoon, Bukit Batok and Sim Ming, there are a couple of major importers and local dealers that have the correct offset for our beloved B Class

The B Class can handle a offset anywhere from 44 to 50 but is dependent upon the rubber you fit.

For example if you opt for a 18" x 8" upgrade with a 50 offset, either a 225x40x18 or a 235x40x18 / 235x35x18 will fit nicely.

However if you happen to have lowered your B Class with the Carlson or Brabus lowering kit all bets are off with the 235 tyres as they will more than likely scrub on heavy braking & cornering, or the beloved Mall speed hump.

There are premium 2 piece japanese rims, single piece Japanese and Italian brand rims and also the very nice Brabus or Carlsson rims available.

There is also the option of staggering rim widths to make your B Class look like a Super Stock Drag racer! (Not quite) where you can opt for Offset F44 & R49 which looks way cool but really is a pain if you intend to do front to back rotation with todays directional tyres. Not real practical, but Great to look at and dream.

When you do change for the new aftermarket look "Watch your lug bolts", Merc use Radius Seats (Rounded) on the collar, many aftermarket rims use taper seat (V Shape) collars.

So more than likely you will need to change your lug bolts.

The bolts on the B Class are Radius Seat (Rounded) M14 x 1.5 the threaded portion to the collar is between 24mm to 28mm.

Do not extend too far past this otherwise you may end up scoring your brake disk rotor due to the bolt threads extending past the point of no return. :tsk:

Also if your looking for Rim Locks to protect the new investment when playing golf in Johor or shopping in JB, look for McGuard, but I must warn you these rim lock bolts cost.

Same principal if your new rims have Radius Seat (Rounded) then you can opt for the genuine Merc accessory Rim Lock which is cheaper. (Yes really!:shocked:)

If you opted for rims with tapered seats you may need to seek McGuards

Overall M14 x 1.5 the threaded portion to the collar (Radius/Tapered) is between 24mm to 28mm.

If you are wondering about the Tire Pressure warning with the new rims, don't as it works fine due to the sensors being allocated in the stub axel assembly not the wheels themselves.

Just reset with the + button at 28PSI and then ask the tyre dealer to pump the pressure up to the correct rating.

Hope this helps you all as it took a lot of trial and error and research to get this right. But really fun indeed....now all the tyre and rim uncles and aunties know me! :becky:

Regards

Des

Thanks for your contribution. Let's make this a sticky guide for B klasse owners! :becky:

Hi Des,

You sure did ur homework,and appreciate your sharing of infos.

[Guest desmo]

Hi All,

Once last thing to remember when changing the rims and opting for tapered seat wheel bolts over radius seat bolts.

Remember to keep at least 5 of the original Merc radius seat wheel bolts.

The skinny spare wheel needs the original Mercedes radius seat bolts.

This is indeed important if you are keeping the original factory spare and you get an unfortunate flat, as the tapered seat bolts will not be a good solution to get you out of the trouble your in with a flat tyre as they will not be a correct fit for the skinny rim. :becky:

Just some food for thought for all car owners changing away from factory rims.

Sorry for borrowing this thread .. as never like anyhow start new thread when an appropriate is available for a topic.

Was chatting with another B-class bro yday, sharing wat minor after-market touches we have done. One leading to the other we soon touch on rims/tyres.

I am currently looking at available options to up size the stock 16s to 18s.

Have tried the usual shops, seen quite a no. But somehow it seems quite hard to find a nice set with the peculiar spec for the W246.

There are quite good options for 18x8.5 offset 45. But for the W246 that will protrude out by couple of mm. 18x7.5 is a rare find .. and a compromise maybe 18x8.

Does any bro here have any luck and can share ?

Best if you can post some picts here to show your swee swee rims.

Cheers Bros and look forward to your sharing

IMHO stock is best. Been through that path unless you might want to consider shipping from Europe.

[yc3333]

Denwee, what do you mean by protrude out by a couple of mm? Protrude out from the fenders? 

Many people change rims in order to get the "flush" look. 

 

18X8 rims should be quite common in the market.

 

If all else fails, go for custom rims  

[denwee]

Out of fenders I mean

Yes ... 18x8 quite common ... but most offset at 3x .. so out by approx 3mm was told

Anyway I found an original merc design at 18x7.5 offset 52 ... fit sui sui de

[denwee]

Finally found time to put on the new shoes yday.

The fitting was perfect and nothing the AD can fuss about as kept all to recommended specs.

Design wise I wont say much as not easy to find ... but very unlike my usual rims choice .. haha

[denwee]

Just to share .. the original stock bolts fits perfectly and also the wheel cap ... no extra money spent on this

Just something to remind bros who planning the same ... remember to ask tyre shop to remove the pressure sensors and install over

My installer did not do so as did not knew about it .. good thing they are honest and reasonable. They have to redo the whole works when I went back to them.

so Chio!!! Btw my father friend recommend me put 19" rims but the rims is inward not outward jiu can so wont offset much.. but 19 inch rim will burn more fuel like drink water haha.. So i thinking to get 17/18" amg rims will black colour~

[imrog]

where to find rims that fit the B???

[LoneLyBy2]

Every where but recommend choice 17 or 18 so won't offset much..

where to find rims that fit the B???

[Slowpoke]

Denwee your B200 comes with pressure sensors?

[denwee]

Yes Bro

It does comes with those pressure sensors that looks like the typical type such as Orange TPMS

It does give u the pressure reading but not as instantaneous like Orange

[Slowpoke]

Mine don't have Leh. It's joined to the air valve right?

[denwee]

Yes it is.

Yours which YOM

I heard some sensor is in-built in the hub assembly not on its own.

[Slowpoke]

End 2013. What is hub assembly?

I changed to 18 AMG I insisted the tyre shop to strip my stock tyre for me to see. The valve doesn't have the butterfly thing.

[denwee]

Bro I hear the tyre shop say one.

Cos when I changing rim I told him to remember to remove the butterfly.

Subsequently I have to go back to him when it fails to pick up the pressure .. then he says some merc dont hv the butterfly de, built-in to the simi hub. Didn't bother to inquire more as long as mine works

Got butterfly no butterfly as long as got pressure reading can liao lor.

Got butterfly but batt dies later .... money fly.

[Slowpoke]

I don't have any pressure reading. Only have Runflat indicator only. Maybe you're right.

[denwee]

I don't have any pressure reading. Only have Runflat indicator only. Maybe you're right.

 

Oh ... then boh bian liao

 

U tested how low it needs to get before it warns you ? 

[Slowpoke]

Err no. I usually pump the Tyres once every 2 weeks. Pressure was ard 210-220then.

[denwee]

I think it has to drop much lower.   maybe around 150 ? 

Never has it alerted me, as I always check tyre pressure on a weekly basis when its time for refuel.

 

Unless ganna nail, then suay lor.

[Slowpoke]

choy, don't kena better.
