20's on a w211 pix?
 

I have 19's using 235/35/19 at the moment, I'm wondering how 20's using 235/35/20 or even 245/35/20 will look. Non staggered cause I have a 4matic.

Sorry, no pics, just an FYI for you...To keep stock rolling diameter, you should run 245/30/20 tires on a 20" rim

Here ya go..

Look at CC_350's car. He has one of the sweetest looking W211's out there. His wheels are staggered but you can get and idea.

35 series is probably the most I wanna go. 30's won't be practical for a daily driver. I do 60 miles average a day. weekends, is about 100-200 miles, if I went with 235/35/19 I think I should be ok because 245 would actually have a little more side walls than 235,

Thanks for the link Benzo...

after seeing the w211 on 20;s I think i'll stick with 19's.... 20's looks kinda off for some reason.

Keep in mind that your speedo will be off if you put 20s on with 35 series tires. The sidewall on a 20" tire with 30 series sidewall is the same as 19" tire with 35 series tire. No different. Remember, it's a ratio for height/width in mm.

I had a set of 19's on my E500 4MATIC and upgraded about one month ago now and love the look of the 20's, but not so much the ride. Bumps are HARSH now and when I pulled the 19's off to give them to a friend, noticed a small dent in the lip which makes me think these 20's probably wont last a year. But, I guess that's about when I expect to trade in the car so Cest la vie. If you do drive 60 miles a day though, I would stick with 19's for sure! They look great and ride great. Best of both worlds.

Cheers,

Here are some pic of my car on a 20" rim.

My friend and I did a photoshoot on our cars the other day and he posted in the BMW E90 forum anyways here it is. I'll post bigger pics later if you need it, but my rims are staggered and 245/35/20

Anyone know if that is the only problem with changing the stock diameter of the wheel/tire? I'm trying to decide if I should go 19" or 20". If I go 20" I don't know if I want to run a 30 series up front and a 25 series in the back. That's what it would take to equal stock diameter.

If you go with an overall larger diameter you will have an incorrect speedo and also have the potential for rubbing, especially if you lower the car. Rule of thumb is to always keep the rolling diameter as close to stock as possible.


Take a look at this and it will help you

Very useful calculator
 

Thanks for the info above.

Another question...

Is the speedometer only affected by changing the diameter of the front wheels only or will changing the diameter or the rear wheels also affect the speedometer?
