Hello guys,

I know there are lots of experts in this, I have just decided to go for 20" wheels for my W211 2004 E320

my 1st question is that should I go for :

20x8.5(front) and 20x9.5(rear)

or

20x8.5(front) and 20x10(rear) <-- is this 10 width can be possibly fit into my car?

2nd question will be:

could you guys reccomend me tire sizes both for better ride and without doing any modification anymore to my body after I put on my new 20" wheels on and tires later on...

I heard some say and read from the forum that tire setup 245/30/20 (front) will do fine for my car but I am still not sure about this.. could someone clarify..

and what is really 'bolt shave' really means? which part of the bolt should be shaved if something wrong?

last question, I know that I would need to do some lowering after I put on my 20" into my car, and I know that there are some sport springs such as Eibach and H&R, could any1 tell me which one is better or which one is giving more drop or maybe which one is the cheapest or maybe the best ride :P

I know that my questions probably too much and stupid, so please forgive me...

and could any1 just tell me how much is coilover would cost, maybe the cheapest one.. and is it worth it?

thank you thankyou...

On an E55 you can run 10.5 rears... not sure on the e320. Not going to get much help in the lowering department being that all of us E55 guys have airmatic suspension and we lower our cars electronically. Although, when I had my C55K I was running the Bilstein coliovers and loved them (paid $1,800 for them)

Not sure if this is going to help you but I'm running:

Front: 245/30/20 x 9.0
Rear: 285/25/20 x 10.5

hochi

How come you can't run 10.5's in the back for the e320?

Elite

thank you for the reply and recommendation dragonAMG, but yea.. since I really am a newbie in this as what hochi asked, why I cant put 10.5 in the rear? could it be E55 has bigger space for wheels in the rear than regular e320?

thank you

Vic55

Same body so I dont see why not. The E320 has smaller brakes so you could possibly even get a more aggressive offset.

Elite

so 10.5 --> is a positive doable in E320 W211 ??????

how about the front... could any1 confirm 9.0 is doable for the front?

thank you so much guys, I really appreciate for the fast reply...

thank you thank you

dragonAMG

I said I'm not sure... because I honestly have absolutely no idea.

Like Vic said, because you have smaller brakes you can run a more aggressive offset, which means you might even be able to run wider rims than us with a deeper right.

Call Ben @ wheels boutique (www.wheelsboutique.com / 1-866-51-wheels)... he knows all when it comes to wheels. Tell him that Josh sent you.

Elite

thanks for the reply josh.. I thought I was almost sure for the those width you mentioned.. fiiuhh..

does any1 have any opinion from experience of the 20" wheels they put on... suggestion from 20" owner please say something....

is 20x9 and 20x10.5 doable?

cuz, before I heard this from you... I thought the max width I can put is only
20x8.5 and 20x10 (this is base on my research so far.. but I was surprized when you said for those width... now I know that is not confrimed yet)

thank you

Elite

any help from 20" wheels owner will be appreciated.....

Assuming you own a standard 2004 E320, I believe your stock wheel consists of a 16" rim with 225/55/16 tires. With that said, most folks plus size a maximum of two. You want to plus size four (20 - 16 = 4).

Note:

1) The most important measurement in aftermarket wheel upgrades is wheel diameter. In your case: 25.74 " Hence, 245/30/20 (25.78") front/ 285/25/20 (25.61) rear would the optimum choice in terms of tire size. Any larger or any smaller may produce adverse effects to your braking and suspension components.

2) A 285 sits perfectly on a 10" rim. Forget 10.5". On a side note: most E55 owners will not fit their rears with 285's....too much "wiggle." Then again, an E320 may not provide enough traction to produce a "wiggle."

3) H&R Super Sport Springs provide the best drop: 1.5+"

4) Plus sizing four drastically effects section height. Section height is the amount of rubber between the rim and the pothole. I.E.: stock section height is 4.87"; aftermarket 245/30/20 is 2.89". 4.87 - 2.89 = a loss of 1.98".

5) Disregard #1 through #4. And, with all do respect, return to the drawing board. Plus sizing four on an E320 would require more than springs and shocks to maintain the integrity of the ride.

Elite

thank you for the very detail explanations rrrruBENZ///E55

now I am sure that I will go for 20x8.5 (for the front) with 245/30/20 tires

and

20x10 (for the rear) with 285/25/20 tires

again thank you so much..

rrrruBENZ///E55

Your welcome. I just noticed your signature indicates the presence of an AMG Sport Package. I missed that on my first post. Disregard #5: 5) Disregard #1 through #4. And, with all do respect, return to the drawing board. Plus sizing four on an E320 would require more than springs and shocks to maintain the integrity of the ride. There is some hope for an acceptable, though slightly rougher, ride. Good luck with your modification.

Of course you can fit a 10.5 on the E320. You can probably do an 11 rear if you wanna roll the fenders a bit.

Elite

BlackC230Coupe,

can I know base on what you say that I can put 10.5 in my E320? do you have experienced that by yourself? or you just assuming?
what about the front? do you also think width 9 can be done for the front ?

( I'm sorry the reason I am asking this and that so many times is that because I am on the very edge about to buy my wheels and I am trying to get as bigger lips as possible, but I dont want to get a wrong size that would make me have to return the wheels because it cannot be fit into my car.. so please help me....

thanks again

dragonAMG

BlackC230Coupe owns EuroteckMotorsports and knows his wheels too. If Neal (BlackC230Coupe) says it will work... it will work.

rrrruBENZ///E55

Surely, BlackC230Coupe speaks with credibility. Nonetheless, it has been my experience that a 285 tire mounts perfectly on a 10" rim, and that going 10.5" would best be fitted with a 295 tire. My point being that adding width to the rim requires adding width to the section width. Also, increasing the width on the rear without increasing the width on the front (which BTW I would not recommend due to roll resistance and handling issues) decreases the balance of the setup. I.e.: Too much grip in the rear may contribute to over steer up front, and you will find your front end sliding through a tight turn. Elite may want the widest rim in the rear, and 11" is pushing the envelope, but the widest rim which requires a wider tire is not necessarily the optimum choice. Elite: Stay with the 285 10" setup. It will work, and it will ultimately cost you less to maintain. Just my two cent.

Elite

I agree you both rrrruBENZ///E55 and BlackC230Coupe are professionals in these type of situations.. and again thank you verymuch for your detail explaination again rrrruBENZ///E55.. and it does sound makes sense to me, yea.. I guess I will get 10" width then.. just for safe.. and for sure I realy dont want to do any fender rolling or anykind of modification...

thanks again guys...

I am planning to install Renntech Lowering Module and then install either 19 x 9.0 front and 19 x 10 rear or 20 x 9.0 front and 20 x 10 rear but my worry is if the 20's with the lowering will rub or make any negative effect. I know 19's will go good and the wheels which I am between are the HRE 945R OR 948R. Another alternative MAYA DTR! either style in High polished. What do you Benz fans think?

BlackC230Coupe

Yes, i have done 10.5" rear wheels on E320s and E500 before which have the same fenders and everything. The E55 does have fenders already rolled a bit more then the other 2 cars.

The 10.5" rear works great. Usually does not rub, but if your car is lowered, you may be ok, or you may have minor rubing and have to roll the fenders. If you are trying to decide between a 10 or 10.5 and your reasoing for going with the 10.5 is or a larger lip, well that depends on the wheel. On some wheels the .5 wider is easier to get a larger lip. In other cases, it does not get you anything at all, not a larger lip or even a wider tire. Some people (and a lot from what i always see) just like to know they like to have the widest wheels possible on the car.

For the front wheels, 9" also works fine. I do 9" and 10.5" widths on the E-class all the time. But again like i said, sometimes the width does not gain you anything at all.

What kind of wheels were you looking at?

Elite

Thank you again for your professional input BlackC230Coupe, ohhh mann.. now I am not sure what to get anymore..
okay I will go for 20x9 and 20x10.5 then... if the wont fit.. I'll think about it later.. :P

and I have one last question for you BlackC230Coupe, can I know what tire sizes do you use when you put 20x9(front) and 20x10.5(rear) wheels on those w211 Eclasses...

thank you very much...

BlackC230Coupe

Well, as long as you go with custom wheels with custom offset in 20x9 and 20x10.5 you should be ok. If you go with off the shelf type wheels you will probably not be in as good of shape.

For tires for 20x9 go with 245/30/20 for the 20x10.5 go with 285/25/20.

Good luck!

esport: My current favorite rim upgrade is a toss between Maya STM and Maya DTR. The former being sporty, and the latter being sophisticated. Frankly, in order to remedy lowering clearance issues, I would chose 19 X 8.5:245/35/19 front + 19 X 9.5:275/30/19 rear. Also, both sizes are fairly close to your 25.68" stock wheel diameter. Just my two cents.

BMWEATR

Just put 20" maya stm graphites on my car went from ps2's to p-zero's(the p-zeros are pos compared to the ps2's)
