Unimog Club UK

Hello Brian,
Thank u for such a comprehensive respond. If it's just a characteristic of the tyre then what maker would u advise me to the best? Moose advised me Dunlop would a right choice as all round tire. I'd like to listen to as many advices as possible before investing in tyre change.

Thank u.

Personally I'd go with Moose's (aka, my Dad) opinion. He has a lot of experience with Unimog's and I learnt pretty much everything I know about them from him.
One thing I would note in terms of wear, it seems to be the chunkier tyres that have the most unusual wear patterns.
I personally like the Michelin XML tyre, it's very impressive offroad. However, if you're going to be doing a lot of road/surfaced track driving, then I wouldn't bother with the XML, as it's an expensive tyre and wouldn't be worth the investment, it also has a tendency to have the unusual tyre wear.

I may be totally wrong here,

but could it not just be the tyre compound? as it looks like its wearing in an a-b-a-b kind of pattern.

not that I am from an offroad background, but it looks to me like it could be a tyre that's almost 'all purpose' so the nobbles would be in rows of hard and softer compounds?

like I said I am most likely wrong, but hey ho

It could be  this, would certainly make sense, the only way to find out if the compounds were different is to contact the tyre manufacturer themselves.

Cheers, Brian

I plan to fix the tire on the spot where the fire extinguishers are

Hello Moose,

Thank u for your advise. I'm still thinking about the spare tire mount in this particular case. Have checked the rear wheel for the play but it's fine. Looks like the camera took the pic in that way.

There's one thing I'd like get your advice. I'm also thinking about mounting the exhaust pipe up along the cabin on the driver's side. I've never been inside of cabins that have that kind of raised exhaust pipes. I wonder how noisy it would be and plus what would be possible measures to not allow the exhaust smoke enter the rear body during the drive.

Pls advice me.

Thank u,

Mongol

Hi Mongol
If you can the best thing to do is buy the genuine exhaust the problem you have is your spare wheel and that you have long exhaust you can buy and fit the parts and the upright pipe but it will cost a fair bit ! Let me ask around as sometimes these parts are available used.
It won't make any difference to noise in the cab as its not physically conected to the cab upright, also the ambulance body is standard ? So will not cause any problem.

Hi Moose,

I already have the genuine exhaust. Purchased it 2 years ago but still have headache with the spare tire mounting problem. The back body is standard. But I did a lot of things inside of it. First took off the original heat and noise isolation material. Secondly painted the whole inner metal area with the special paint (bought from Russia. they say they use it on the space crafts. 2mm thick paint layer equals to 6cm isolation material).  And I think that's true cause I've tested it in really hot summer days and in really cold winter condition. Under the direct hot sunshine the back body is still cool. No need for additional fans or air conditioner. Winter case is a bit different as a lot of cold air goes in through the windows. But I believe the paint still helps to keep the warm temperature. Then I mounted a basalt wool pieces in order to be more sure regarding the heat isolation. So the exhaust noise will be heard very little in the back body. Not sure about the smoke though.
Just wondering about the driver's side in the cabin. As the driver is myself it would be very difficult to hear that exhaust noise all the time right above  my ears. Therefore would like to hear of your experience as much in details as possible before I decide to make this move.

With respect,
Mongol

The upright is totally seperate from the exhaust I've driven hundreds of Unimog tens of thousands of miles some with upright exhausts and some without, you cannot tell the difference 😊 And I'm blessed with with good hearing
Is your engine a bit smokey ? Blue on start up or black under full load ?

Oh, thank u for your encouragement. That really inspires me. then I'll keep on thinking about my little project. As for the engine smoke I can't be sure. Under the full load it sends out a dark smoke. Can not tell the colour. Haven't noticed on the start. But I would say the engine is smokey.

It's not garunteed but it's good practice when you put fuel in your Unimog put a litre of two stroke in the tank before filling up, make sure it's mineral, I don't know anything about the fuel where you live but we have low sulphere and bio diesel blended both of which did not exist when these engines were launched ! The two stroke oil will help the pump with lubrication.

Sorry I didn't understand what u meant by "stroke". What kind of oil is that? Is it the engine oil that we use?

I c. I'll do that. Do I have to put that oil everytime I fill the tank. Or just from time to time?
