A full-size spare - wow.

[51315]

I now have a real-life spare in the boot of the B200, complete with matching wheel and tyre (18") which makes me feel happier than using the gunk bottle.
So now, can someone please suggest a reasonable tyre-changing kit that's not too space-hungry or heavy or expensive - as of course I'm going to need this IF ('never had this in a million miles of motoring'. 'highly improbable', 'so rare, it's nigh impossible') does actually come to pass. Thanks.

Is ur spare a steel or alloy. Get right bolts.

 

[rorywquin]

Do you mean “wheel" changing kit i.e jack, wheel chock, safety triangle, hi-viz & wheel spanner or do also need tyre irons ?

This is what we used to get in cars.

If you’re not aware steel spare wheels generally have shorter length bolts so you need to check this or it could result in damage to the hub

51315 did say 'matching wheel' so it could be assumed that the spare will use the original bolts ....

my twin axle caravan came with a similar scissor jack ..... I tried it at home just to see. It barely took the weight off the suspension let alone lift a wheel off the ground. Every now & then I come across the jack in my garage when I'm looking for something else Absolutely useless!

Bin it.

I hate them.

I had a bottle jack and a hi-lift jack that I used in my off-roading days. The hi-lift terrified me. Fortunately I never needed either one.

U used to be able to get bag Jack's which ran off of exhaust I thought they were pretty good

Yes it's always good to practice changing a wheel before you actually need to, in the dark and rain on the M25.

I think with the SL it's a case of call for assistance, and hope.

Sorry - should have said wheel not tyre-changing kit. Yes, that seems exactly what I need (will investigate) - though to be honest at my age I think I'm more likely to rely on the kindness of strangers. But if it's an emergency out in the sticks it might be wise to have everything to hand.
Better still, the Mercedes guys will arrive in RAC gear and sort it all out.

Yes, the hi lift jack is good for quickly changing a wheel or general lifting duties, but you need someone to hold it, I find. Also Hi Lift sell a jack pad which looks handy.

Correct. Completely matching design and alloy.

Yep, still very tricky to use in off road conditions. I hated working with them.

One thing is to check that the lugs are properly torqued and that you will actually be able to loosen them with whatever spanner you choose to have with you!

Anyone know the correct torque for these 18" alloys - or where to find it, as doesn't seem to be in the book.

130Nm is what the web is saying for a 2020 B Class on 18" wheels

Can I suggest you make up a small demo tape or use a black felt tip marker to write the wheel torque setting on a suitable part of the torque wrench if you are always forgetting like me. About the only thing I use the torque wrench for nowadays. I also bought one of those alloy with a nylon sleeve wheel sockets, they help protect the paint around your wheel stud holes.

Also ensure you wind your torque wrench back to 0 before putting it away - to take the pressure off the internal spring.

(I have a dymo sticker with the settings of all my wheel bolts on the case of mine)

The standard MB tool kit contains an aluminium "peg" that you can screw into a bolt hole to help you locate the replacement wheel/tyre, its a god send in the dark and wet.
Pack a long wheel brace to help you undo nuts, then use a torque wrench or short wheel brace to do them up (the standard MB one is about a foot long) meaning that you can use your foot to perform the final tightening without too much worry about overtightening.
Once mobile again you can always get the torque settings checked afterwards somewhere else.
Check out the standard MB jack, it may fit in your boot floor by the spare wheel. Its okay for a roadside repair (once you've loosened the wheel bolts) but like a bottle jack isn't stable on anything other than level ground.

Until I used mine, I thought it was a bit of a gimmick but, it's pretty handy {though if cars still used studs & nuts instead of threaded hubs & bolts it wouldn't be needed at all )
