18" or 20" on 2000 CLK
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

from the same site
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

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

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.

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..
