Can I install 275/35/19 for the rear rim?
or
do I have to have 275/30/19?
my car is stock and not lowered

I used this link to calculate whether my new "ambitious" 20 inch set-up would fit... and it does! (Its much better than the one on E90post.com IMHO)
It gives you all the dimensions around the wheel / struts / arch etc. So you simply put in the details of the current wheel you are running, add the new one, and it will tell you the differences in space all around the wheel

To answer you question, the 275/35/19 will have an extra 25mm of tyre on the car, which means the tyre wall will be an extra 12&13mm higher than the standard 275/30/19 tyre. You also need to factor in what offset you have, what width wheel and how much you have lowered the car. For example, on my M-Sport suspension, which is 15mm less than standard, and on an OEM rim like the 128 (ET32, 9.5 wide), I would have space for that tyre.

Final question you need to ask, will it look right?! I like the 275/30/19 and would personally opt for the 285/30/19 to make it wider and with only a few MM higher side wall.

Hope that all makes sense!

I will try the link out later on.

it probably will fit if you dont have suspension since another member had that tire size on m166 without lowering spring..

also 275/30/20 fits so i dont see why not... But, just go wit 275/30/19.. .

the 275/35 will help against shitty road conditions, Cheap insurance ya know.

I had 275-35-19 on the rear with Eibach lowering springs and never rubbed once....only when I got 20s!

they fit. no rub. i have that setup with eibach pro-kit. honestly it doesn't look good becuase the tires are so meaty which makes the rear wheels look even smaller. stick with 30's.

any photos of your car to see how fat they are.
But id the ride alot better?

the 19" wheels I had used 245/40/19 in the front and 275/35/19 in the back. no rubbing in the back on only slight rubbing the front when turning, braking and going through a dip.

I liked that setup a lot because of the better ride and better pothole protection. Here is a side shot:

285/30/19 is perfect for the rear when paired with 245/35/19 up front. The 275/30 has too small of a sidewall- However the 275/35 is tooo much sidewall-just like the above picture-why would you wnat to rub when you turn? The ride is perfect with teh 285/30/19, you can adjust your tire pressure for a more comfortable ride-plus it looks wayyy better-look at the pic above-wayy too much tire and not enough wheel-you dont want your car to look that bad

[FRONJONI]

hey xenon the car looks really good with the m6 reps...almost making me re-think suggesting you to go with the 20" swiss.

If you dont HAVE to run a 30/19 then dont. Adjusting tire pressure to make the ride more comfortable on thinner tires risks bending your wheel. The tire wont absorb the shock from bumps if you reduce the pressure to make it softer. It will also decrease your mpg and accel. This is something I used to do when id go for a spirited drive through the canyons in my mini.

275/35/19 is perfectly fine, and most people run that. Unless you have a specific look you're going for, which it sounds like you dont, then that size is good for your setup.

I run 275/35/19 in the rear on h&r sport springs, and i dont have any rubbing.
