Do we still need spare tyre in SG?

i have been told that the spare tyre actually serve as a safety protection to buffer against rear collision...with the impending problem with some insurance companies finding ways and means to void our policy...something worth pondering in case someone suffers a whiplash or injuries to the rear passengers caused by a rear-end collision...:Cry: :Cry:

Good point! In any case, the spare wheel/tyre is the skinny type...no difference in weight & doesn't eat up much space.

If really don't want spare tyres, I strongly suggest that you use run-flat tyres. They cost more & have a harder ride.

Just did the 0 to 100km test, 1sec faster :becky:

Last time long long time ago, tyre got inner tube.

Once pang chek all air came out. LL got to change tyre.

Nowadays tubeless power lah! Got puncture usually nails & screws, air slowly released.

With most of the newer MB rides with either TPMS or tyre pressure loss warning, we get plenty of time to get it fixed. My car got an air pump which helps too.

However in MY with higher speed & road conditions though remote U might get an exploded tyre. Tyre once aged and hardened especially more than 3 yrs old tend to explode under high speed & temp.

Happened to me twice in Batam.

Lucky both time, managed to control the vehicle & bring it to a stop.

Changing the huge 265 tyres, U can get hernia!

Rp 2 worth!

Just to share:

The tyre pressure loss warning not very useful, at least for me.

2 weeks back, my passenger side rear tyre kena "screwed".

PSI drop to 140 kpa.

No warning leh. sad.. :Cry:

bro...probably you did not reset after you changed or rotated your tyres...it is a good practice to reset the warning system everytime after pumping air :becky:

Brudder Lei Gong,

i got reset b4.

even if no reset, original reading cannot be ard at 140kpa.

other 3 tyres all at ard 245kpa.

taboleh "beh learn"..

it remains as a puzzle to me til today.

unless, kpa must drop til like 40kpa for the warning to kick in. :confused:

i experienced that before on the W212...the red warning message came on and immediately I drove to the nearby tyre shop and true enough they found a nail in one of the tyre which i can't really tell...:hand:

Here is the data log using PerformanceBox (Please look at the highlighted part as some other reading is just normal acceleration):

2011-07-23 (Accel Test)

- With Spare Tyre Set.

- The rest of the setting same as 2011-08-06.

- Without using launch control. Normal start from 0 rpm.

- Road is smooth and flat (wet).

- 0 to 100km/h: 6.49 sec (Best from 3 runs).

2011-08-06 (Accel Test)

- Without Spare Tyre Set.

- The rest of the setting same as 2011-07-23.

- Without using launch control. Normal start from 0 rpm.

- Road is bumpy (dry).

- Can get better timing if the road is smooth and flat.

- 0 to 100km/h: 5.51 sec (Best from 1 run).

If use launch control defiantly can save another one or two second :becky:

This I not sure, but from friends who track mention 17" is the best. Yet to find out if it is true or not. AMG light-alloy wheels are good enough for me unless our car can fit lambo carbon fibre wheels.

Taking out seat, actually will work, friends who track do take out their seat sometime, even dismantle the whole interior to lighten the car. And put back later when they come back from track.

If I do decide to cut some more weight, option is to get carbon fibre parts, remove the convertible motor+parts and change the suspension. That will be the day I join F1 racing Unlikely as enjoy the car as it is, just keep hunting for carbon fibre bonnet and trunk cover :smile:

I experienced it 1st time on the C-Class, while traveling along Clementi Ave 6, the warning message came on, I continued to drive until I reached Taka, finally when I parked the car and came down to check the tyres, there was a nail stuck in one of the rear tyre.

Guys...what's wrong with changing tyres & getting our hands dirty. It's a guy thing that as a serious driver, one must know & be willing to change tyres. This will also go a long way to impress ladies who may need our help.

Incidentally, the repair tyre kit that comes in a can is convenient, but your tyre repair job will be tough. The foam that is coated in the tyre is almost impossible to claen away. Very likely that you'll need a new tyre in the end...

Me concern is only safety of changing the spare tyre along the road, or expressway!

Imagine u not careful something drop roll into middle of the road !!

If is like at mscp or carpark already i don't mind.

[Guest Yap ST]

Bro can teach how to reset it I never try before for my C200 or C200 do not have this function ?

Bro, C200 have this function, here is the steps:

1) Scroll to "Service"

2) Choose "Tyre Pressure"

3) Press "Ok"

4) Choose "Yes"

5) Press "Ok"

My spare tyre was removed from my E250 too and using the extra space for storage. Good place to store durians!

In my W212 E250, the spare tyre is actually the same 17inch rims as all the 4 rims, and the tyre is the same original one. Definitely not the skinny type like I used to have for my previous BMW. So it is quite heavy and clearing it out should help save some fuel and increase acceleration.

Used to have 19inch runflat bridgestone tyres on my BMW 523i. More noisy than most other performance tyres, but it helps to provide a peace of mind if you travel to Malaysia.

Have been driving for the past 10years, and have never changed tyres on my own on the roadside. Since I don't drive to Malaysia, the spare tyre is not required as you will likely be able to look for a tyre shop nearby, likely at those bigger Shell station.

Cheers!

what spare tyres? in my store room for many years liao:shocked:

[Guest SL63AMG]

Hahaha ok ok, got the idea :becky:

The next question for those who take out their spare tyres, do you leave the car jack in your car?

I still keep it as I notice the jack for SL63AMG is different from the standard one.

[Guest Mark_twain88]

My whole set is in my storeroom (spare tyre, round toolbox with car jack, wrenches, etc).

Guess won't need any of the tools since I don't have a spare tyre in the car anyway so no need to jack up the car?

The empty space very good storage space now!

[Guest blackknight]

but you may need a screwdriver sometime?

[Guest Mark_twain88]

What type of screwdriver and for what likely purposes?

Haha...
