Spare tire?

Wallance · 11-11-2006

Hi, as you guys know that I have changed my wheels from 17" to 19", so now is the spare tire in the trunk actually useless? Should i just take it out too reduce some weight?

**DansSlk** · 11-11-2006

Totally your call mate.

If your removing it maybe try also removing the liner from the underside of the engine hood so its a even loss from both the front and the back of the car.

They both weigh about the same.

Ynot · 11-11-2006

Although I haven't remove mine yet, it's not wise to use it with your 19"s, the diameter is off and can ruin more than just your alignment. IMO

If you feel the need to go somewhere far, I would put the factory wheels back on and put the spare tire back in. Just in case something happens on the road.

Yesterday I took a look at my spare and it appears that it is damn difficult to remove. It also looks like it has a very low profile.

The SLK 55 doesn't even come with a spare. Instead, you get a can of that goop to squirt into the tire to seal it (and ruin it) and a mini-compressor to refill the tire, if the bead is still intact. Then, you can make a quick run to the nearest service center. Or you can call Tele-aid for a trailer ride. Needless to say, I don't take my 55 off the beaten path without checking the tires religiously.

Seriously? here in the UK it comes with the space-saver spare stupid heavy thing it left the car the first day it arrived.

And the space it was in is now used for the water tank but before that i used it to store stuff in so i had a little extra space with the roof down

Wallance · 11-12-2006

reallife + dansslk: I think there is a run flat tires option for the slk?? tha'ts why there is no spare tire? but yea that space for us haf those mini compressor and tools there too.

Ynot: yes if there is no use for the 17" spare tire cause i have 19" wheels and if i usethat it will ruin my car then i will take it out for sure.

dansslk: wow for water tank? as in water cooling water tank or wut?

cockscrew: yea the space for the spare tire is pretty tight but if u slowly slide it out and pull it out in an angle it's not a problem.

i was thinking of using that space to put a sub or amp in there, i think it's a good spot to do that without wasting my trunk space (it's so small already).

I carry a can of compressed air that has a mixture of gunk in that seals punctures. I used it once on a Porsche that I owned and that tire from then on never lost air. But, that was years ago.

I have not looked under that tire. What is there? I assume tools and a jack. I can not imagine changing a tire in Bangkok traffic. I'd shoot the car and buy a new one.

mtiede · 11-12-2006

The compact spare comes out and goes in easier if it is rocked from side to side while pulling or pushing.

Seems dumb to put the tools below the tire.

Not sure why your wheel size makes a difference. Presumably the large wheel means a smaller tire and the total diameter remains pretty much the same as the original tires? If that is the case, then putting the spare on and pumping it up should make it about the same size as the other tires and should run okay, no?

Of couse, if your total tire diameter is larger now, then that could make a difference, but I can't imagine it hurting for a short run to a repair station.

Of course, the best bet is just push the wrench button

**DansSlk** · 11-12-2006

It does seem a little silly to put the tools under the tire but thats where they go it must be a pain if you need to get to the spare fuses or something having to remove the whole damn tire.

I did not have the choice of anything run-flat for my car and as far as i am aware there are not any run flat options for the SLK55 in the UK i have never seen one mentioned on the computer but its probably different in other parts of the world.

The water tank is for engine / tranny and diff cooling it runs from the trunk to the tranny back to the diff then forward to the engine since it it quite stable temp wise it then goes into a small radiator mounted in the side vents of the bumper on the right side of the bumper (looking from the trunk) since the oil cooler is only on the left and from the rad it goes back to the pump and starts over.

I've done this a couple of times just to see what's underneath. I found it easier to push the spare tire towards the front (after removing the screw-on anchor) and lift the back of the tire. It is a very tight fit and will rub against the black plastic panel near the trunk/boot latch area.

Don't do this if you have a hernia.

Cyberdrakon removed all the stuff in there and has a traveling wardrobe instead. Impressive too.

To paraphrase Jay Leno, it seems to be another "what the hell were they thinking" episode. They had it right in the SLK320. The tools were on top. It sure seems like they could have done it the same way in the 350. I can't think of any reason they switched it.

Now when I want to switch to the winter wheels, I have to pull out the spare to get to the jack and the other little helpful tools.

Makes no sense to me.

You do know that the tire needs to be inflated right? There is a little air pump in there to blow up the tire. With as much trouble as it is to get the spare in and out when it is totally deflated, I can't image how hard it will be to get it in there after having been inflated...

Hi, as you guys know that I have changed my wheels from 17" to 19", so now is the spare tire in the trunk actually useless? Should i just take it out too reduce some weight?

-----------------------------------------------------------------------------------

Spare will be OK as overall inflated size will match whatever rims and tyres you put on the car.
Rim size doesnt matter at all just overall size to tread face.

bejak · 11-12-2006

Isn't the inflated spare wheel diameter same as the original wheels? Then it should not matter if one has changed them to 17, 18 or 19 inch. If you have chosen the correct tyre (tire) profile you still run on wheels which have the same overall diameter.

Bazzzle, I'd agree. Generally when you get a larger wheel you get a smaller wall height on the tyre or lower profile so the diameter is very similar. well unless you go up to silly sizes. I think this is the case. guess you can check if you know the original sizes.

i.e. if its a 225/45 with 18"rim then (18*25.4) + 225/100*45*= total dia in mm. I'dont thing 10-20mm is a huge problem for the short distance you'll be ususing the space saver for.

*easty* · 11-13-2006

I just did this comparing a 16" and 18"

16 with a 225/50 = 533.9mm

18 with a 245/35 = 542.9mm Pretty close.
