245/35 rubs and is out of the question. I don't mind an aggressive stance, and I can always adjust my drop if I wish to change it up. Besides, 18mm is child's play considering that's cut in half due to the central location of the hub. 9mm... woohoo. I think they'll be fine.

That being said, as an update, they sold the tires out from under me yesterday so I had to ask them to order some new ones. They should be going on tonight.

Bbs LM 20x10.5 rear, 36 offset running 295/25/20. Slammed with no rub whatsoever. Had my rear fenders rolled and pulled a tad. Will run 305's with no problem when these tires wear out.

Remember moving up a width means roughly only 5ish mm of space needed on each side of the tire.

Oh, and I'm running Michelin pilot a/s, which have a VERY squared sidewall

This is 275/25-20 on 9,5x20. (Dunlop SP Sport Maxx GT)

Just an update, went with Toyo 295/25/20's slammed, sport 2, spirited driving NO RUBS, infact tons of room still left for maybe a 20x10.5 with a 305 as long as offsets are good. Might need slight roll/pull but would look SICK.

I am having a set of Cargraphics 20x9.5 and 20x11 in the rear being done by B. Gorman I know i will have to roll and pull, However I was looking for opinons on tire size. I am going for the stretched look, B. Gorman sent me the centers of the wheels which my company is doing in Carbon Fiber and they are some heavy duty quality centers in my opinon. I dont know if anyone has any feedback on the cargraphic wheels. I would like to here some feedback. thanks.

Even a 285 on a 11" will stretch, I personally wouldn't do it, but to each his own.

Good choice. I had the 30-series on the back, however my next set of 20's will have the 25 series.

What wouldnt you do tbal, 11s in the rear or the stretched look.

Oh Damn Tony, nice choice! You make me wanna do smth Ive never wnna do again - run 20's. Damn you T.

11s would be I'm just not fan of stretched tires on Benz/Bimmers... Although a 295/25 on that 11 would be just perfect pending right offset etc

So, in terms of what is the correct fitment to maintain the most correct overall diameters and load ratings, what woulf be best for this:

20 x 8.5 (25 offset)
20 x 10 (35 offset)

2007 E63

Well they are being custom built from the ground up working togther. B.Gorman had the car for the day and we went over the different fitments from A to Z. so the offsets will be perfect. If they are alittle to aggressive we will bump it down to a 10.5 rear. The 11" rear will run a 4 inch lip. So I am pushing for that to happen, and with the right offset the tire wont need be stretched to the point you get it confused with an audi. We will see in the next week or so, My company is finishing up the carbon fiber centers and shipping them off to B. Gorman for completion. you can see in his video under classifieds some of the stuff we are working on together.

running 225/35/20 and 275/30/20 on my 2010 c300. Rolled fenders but still rubbing. Any suggestions?

Suggest you go to a 265 tire

Suggest you ask guys in the C class section

I wonder what the ride quality is like on 25's. the sidewall is tiny so every bump in the road is probably amplified. Then you also have to consider what the extra pounding it does to your suspension. It looks great, but I am running 30's and can see a big difference in ride quality from stock.

What size did you use up front Tbal?

On one hand we are all in love with 11 s in the back .. in my case on the CLS I can fit 11.5 rears with 305 easy with 9.5 fronts......on the other hand we are all trying to lessen the weight ! 11s will weigh more than 10 and 10.5 .. and the larger the tires the more weight also .. if the offsets are correct and planned right , one can achieve the best look with 8.5 fronts ( will take a 255 ) and 10 rear on the W211 and 10.5 CLS ( which will take a 285 nicely ) and save on weight .
what do you guys think .

I dont feel much difference between 25/30 series at all... post some more pix of your car! Love the 144s

245/30

regret not going 20x9 and 255/30
