Hi

I have just purchase another G.  This one a 2011 350G running 18 inch wheels.  The tires currently are 265/65 r18 and I would like ot go bigger, but have been told that cannot from multiple tire dealers.   They tell me that it will mess the gearing up.  My old G ran a 15 inch rim with 31/10.5 r15 tires.  These are bigger.  Why did Mercedes opt for smaller tires on the newer ones?

You assisstance would be most appreciated.

Barry

Hi Barry (sharon),  (sorry you had multi-posting issues - its a quirk of the site intereface!)

Congrats on your G.  I have just got the same (G350) and love it.

I was impressed by how 'large' the wheels and tyres are (I think I have the same as you, R18).  My older 460 is (I think) on R16 wheels.

So...I assume you mean putting even bigger 'wheels' on?  Can you even get R19+ ?  Or put R18 knarly tyres on the R18 rims.  The effect at the speedo would be nominal.

Interested to see what others have to say are the options.

Thanks JDring.   Yes, I am quite excited.  I have got it yet, but know it has some brand new Bridgestone Duellers on it that I am going change out and sell for BF Goodrich  All Terrain.  I have had two sets of these and love them.   The tires are bigger on my G Wagon even though the rims are 15 inch.   I find it kind of odd that Mercedes are putting on the smaller tire.  Maybe it is about fuel consumption.   The tires for the 18 inch are a heck of a lot more that the ones for the 15 inch.  I find that odd also.  

it is Barry by the way.  Tried to get it changed from Sharon, but this never happend.   I used my wifes debit card and the name Sharon stick with the subscription.

I can get that changed (to Barry) if you would like.

Also not sure I understand what you would do with tyres?  You cannot put R15 tyres onto R18 rims.  All you can choose is 'wider' or deeper profile.  So R18 265/75 or  or R18 275/xx

That's my understanding anyway.  What am I missing.

Yes, if you could change it, that would be good.

Yes, you did misunderstand me.   I am making a comparison to my old g tire size on 15 inch rims.   They are bigger than the ones on the 18 inch rims and more money even though they are smaller.   As you know on the newer G350 they run a lot of 165/ 60's and older ones the 15 inch rim with a 32/10.5.  Even though the 165's are smaller tires, they are much more money.

I was told that the gearing and handling would be affected with  R18 265/75 or  or R18 275/xx

That is one thing I am questioning.

The tyre sizes for the different G models have the same circumference:  for example 265/ 60 R18 = 265/ 70 R16. You can fit larger tyres but you have to adjust the settings both for the instrument cluster and transmission module.  The reason:  the ESP tolerates a deviance in the tyre circumference of about 2%.  The difference between 265/60R18 (2367 mm) tires and the popular upgrade 275/70R18 (2590 mm) is about 10%. Without adjustment the ESP will interfere in faster turns.  There are a number pre-programmed tyre sizes in the G-electronics (and that varies depending on model year), it has been disucssed on this forum before (and there is more if you google it).

Thanks Theo.   If this was discussed earlier in the forum, can you point me in the direction of where I will find it?  There is no search feature on this site.

I will probably leave well enough alone, but I will take a look to see what everyone is saying.  Thanks.
