Decided to change wheels, need advice on size
 

All,

After much research and thought I decided to change my wheels from 21" because of the outrageous cost of tires which have short lifespan and limited choices. This would give me a wider range of tire to choose from and cost will be more tolerable.

the question is should I go:

- 20"x10" replica
- 22"x10" replica

and which vendor is the best to get these wheels from. I need them to be hubcentric.

current vehicle info:

Vehicle: 2009 GL550
Wheel size: 21"


Please advise...

22's will look better 20's will get better mileage. Just depends on what is important to you.

Thanks for your response, I have decided to go with 20".

Next question is about tire size.

can i run 295/50/20 or 305/50/20 on a 20x10 et50 without rubbing in the front?

they are recommending 275/50/20 or 285/50/20, my fear is that they will look skinny and not flush on a GL550 especially with the flares.

The 295/40/21 already is not flush with the fender so i can imagine the 20" with a 50mm offset.

need some advice...:nix:

10" wide with an et 50 will look fantastic.

Great, I was trying to get them thus weekend but formymercedes.com only seem to have the style I want in 22".

wheeltechtuning says they will call me back on monday to get proper fitting.

anyone with other seller you recommend that is reputable?

I use Ebay quite a bit. Just make sure the seller has good ratings and Ebay has the buyer protection on the product and you will be fine.

Thanks for the response.

will look into that.

just bought:

20"X10" Replica

Tires:
i also bought 285/50/20 yokohama parada spec-x.

Now i have to think about moving my TPMS from one wheel to the next.

How easy is it to reprogram if I buy a new or used set?

Looks nice. I wouldn't think there is any programming if you buy the right tpms' for your GL.

Ok thanks, I will look into it.

I sent back the 285/50/20.

I am going with 295/45/20 Parada Spec-X.

I received the tires today, and another surprise, I received the "air suspension malfunction error"

Our GL420 came with 22" after market rims and they do look boss but we do a lot of towing (worried about pot holes and ride quality). Haven't really noticed any mpg drop on the 22's to be honest but I don't look that closely.

We use our GL in two modes effectively long range towing or short range school runs.

Where did you source your tires from?

When buying our car I managed to negotiate getting the original 19" wheels as part of the sale and swap between them when towing or in the winter.

I bought mine from Tire rack, I bought 285/50/20 but I was told 295/45/20 is a better fit and also more aggressive.

My GL went to the shop this morning for the air suspension issue.

The wheels are coming today, hopefully i will have everything on early next week.
