About to get some wheels soon on 2000 clk 320. Cant decide between a set of 18" Staggerd wheels with 225/40 18 and 255/35/18 or 20" with 225/30/20 . Would love to get 20's . Anyone having trouble with 20" and those size tires?

check with William, he got 20
i got 19

Definitely go with 18s. 19s...ehhh, if you really want to push the show envelope but really, our cars looks just as good with 18s without giving up more ride quality and worrying about bending your wheels over the slightest pothole. I strongly recommend you don't get 20s for a few reasons:

a.) ride quality is going to be even worse than 19s
b.) expensive tires
c.) you will more likely than not bend a wheel (almost a guarantee, esp. if it's a multi-piece design)
d.) face looks too big on our fenders

Hey bro I'd stick with 18s unless u were planning to slam it, then 20s would fit but 18s are great for daily driving. I'm on 19s n I love em, I think it's the perfect size

Going 20's depends on what you are looking for and what you are worried about and how much money you plan to/ want to spend. I got 20's and ride quality is great but I also changed out my whole suspension with H&R Sport CupKit and SwayBars too. Running 20's on Pirelli PZero Nero filled with Gas instead of Air.

my ride has 20's with factory suspension and it rides and handle smooth I couldn't tell the difference if I am riding on stock of after market rims !! I have 225/35/20 tires

Thanks, good points. Love the look of the 20" and got a real good deal on a set of MKW 104 wheels. I think I will have to settle for reliability over looks. I really don't want to lower the car or change out the suspension. I used to have a Lincoln LS v8 that had 20" on it, and they rode like the stock wheels and never had a problem. I was hoping I could do the same with the clk.

Jbenz99 good to hear that about the 20's. Now I'm back to square one, although I'm leaning more for a staggered 18 set now. how do you like those projector headlights you have, I was thinking of getting some just like those.

jbenz99

@spillay ..simply awesome they are (projection head lights) my friend is like night and day !! what a difference and better light vision @ night !!!

here is where @ brought them !!!! good quailty and great low price !!!

I have a set of custom one of a kind 19" wheels made just for my clk but i ordered new wheels so these are up for sale, they are a direct fit with not spacers or anything needed. they also have tires on them in practically new condition and i am letting them for for cheap because i dont have the room to store them, below is the link to them and the details.

nitrogen? Any better ride quality or is it just for a stable PSI in temp swings?
Im running 18's if i did it again i would go 19".

Williams707

Well with Nitro being thicker than Air you don't have to worry about checking PSI every month and since I never ran with air in my tires I'm assuming that it helps because with 30 series low profile tires I would also have to assume that I'm suppose to have a ruff ride and feel every bump but my ride is nice and smooth

Im running 18's. Wasn't sure if I would have to do anything to put 20's on and didn't want to pay the extra money for 19's since it is an odd number. Also chose not to stagger due to not being able to rotate them.

spillay

Finnally ended up going with some Advanti racing Staggerd 18's. They look great 255/35/18 in the rear and 225/40/18 in the front and didnt loose too much of the ride. Still rides nice and comfortable. Will post pics soon. thanks fro all the advice.

Silv430ClkR

I was gunna say to go with the 18's but you beat me to it. I just got a set of 19's and if I can do it again I think I would of gone with 18's myself. I find myself looking down at the road for potholes more than looking around at whats going on with traffic and stop lights and such. you made a good decision

Highpass

18's.

big_mike1979

funny u posted it because i ordered mine in black from the same site

jbenz99

I use to have 20's now I have 19's staggered !!

IJMacKay

I have 18 inch AMG 5 spokes on the summer tires, front are 265/35R/18 and rears are 235/40R/18.

No rubbing issues at all, but they do pull side to side in a rut quite easily. Not at all fun to drive.

Might be the FALKEN ZieX ZZE -912 tires?

Not the car, as I run 16" - 5 spoke MB rims and Blizzaks in the winter up here and it it tracks perfectly. Any ideas why the 18's are all over the road?

Thanks Ian

Air is mostly nitrogen (over 70%) and pure nitrogen is not "thicker" than air. It's actually lower in density. It doesn't give you a better ride and although it's more resistant to pressure swings than air, it's NOT immune to them

dlbehrns

I would be curious to know how much, if any, do oversized wheels and rims mess with speedometer and ESP?

bennito0

Dont go with 20's, i have the same size your thanking about getting, and i love the ride, i see alot of cats rides on the side of the road with oversized rims, 18's staggered will do trust me homey!!

I quoted what the Japanese Tire shop told me. Nitrogen is more like around 78% to be exact but that's not my point. If you're going to correct my post at least be accurate.

I do know how it feels from my experience AND as you stated "it's more resistant to pressure swings than air" would suggest a better quality ride.

Week I - Put on my new PZero Nero 225/30/20s, for the next few days it just drove like fecal matter, bouncy and unstable especially around curves and twists. Called the shop and asked if they put nitrogen in my tires and/or if they could check the balance. They stated they forgot to put nitrogen in my tires. This was the first time I've ever driven in my ride with those rims and tires without Nitrogen so it was apparent something was wrong.

Week II - Shop put in Nitrogen and there was a Night and Day difference in ride quality and handling. Even my boss that rides to lunch with me daily even noticed the difference, even without me saying anything.

• Nitrogen maintains pressure better than conventional air
• Nitrogen keeps tires 20% cooler
• Nitrogen-filled tires use less fuel
• Nitrogen prolongs the life of your tires
• Tests show that nitrogen reduces tire failure by as much as 80%
• Nitrogen improves handling and performance

Science doesn't always correlate with experience.



Shouldn't matter as long as you keep within the same overall diameter. I was worried about the same but where I work the military often has radar speed monitors and when comparing it with my speed is always dead on. There was a website if I can find it that discussed the +/- mph differences. Off the top of my head, maybe it was tirebible.com

Josh K

I wasn't inaccurate in any part of my post. I said air is over 70% Nitrogen. Did I google it for an exact percentage? No. But what I said was not inaccurate.

I didn't suggest that - you're pulling that correlation out of thin air (no pun intended)


I find it amusing how you dismiss science that contests your assumptions yet you quote "science" to support your experience.

Well, not really science; a quick google copy/paste of those bullet points finds them on tons of dealership service pages that (surprise) sell nitrogen inflation and websites that sell nitro inflation equipment. I'm still looking for that study that shows Nitrogen inflation reducing tire failure by 80%.

http://news.consumerreports.org/cars...nitrogen-.html

Consumer reports' tests showed negligible difference in pressure loss over 1 year (of course a pr/marketing person could say that losing 3.5 psi vs losing 2.2 psi means that nitro filled tires retain over 30% more air and they wouldn't be wrong - it's easy to turn small numbers into big bullet points, but what idiot really doesn't check tire pressure for a year and is 1 psi worth the money for the fills?)

Quoting what the tire shop told you before they sold you the Nitrogen fill? You sound like a great customer.

Seriously though I hope you're not paying for those fills. Your money would be more wisely spent on a small air compressor for your garage and a good tire gauge.

Williams707

Nice long write up without saying anything

Ok, not inaccurate but misleading by almost 10% might as well said Nitrogen is over 1%

You stated in your post "It doesn't give you a better ride" which is why I tried to explain to you that it does.

This car is my daily, the bullet points I listed correlates exactly with my experience running 20z 30 series PZero Nero Tires.

Regardless of contradictory information, it all boils down to the individual trying it for themselves and making their own judgement. Each individual will have a different experience based on countless factors and conditions. My statement is based solely on my experience with Nitrogen for the past 5 years so people can decide for themselves if they want to try it or not. Typically you will only need to check nitrogen filled tires once every 3 months and only had to refill 1-2 times a year.

BTW: I don't worry about small things like how much it cost to fill my tires with nitrogen, even if I had to do it every month..
