Baby Stretch

Hello World...
I want a little baby stretch nothing too crazy but something noticeable at the same time. I currently am running 18x9.5 et 34? I think wheels all around would 215/40 give me the stretch I'm looking for and would I be safe with this sizes? Anyone running this set up? Thanks in advance.

You're asking if the stretch is safe, or fitment? Why not move to 225/235. That's still a stretch on a 9.5
This is the 215

and 225


I'm running 19x9.5 ET30 front with 245/35/

215/40/18 is actually a decent amount of tire stretch. If you're looking for baby stretch, perhaps a 225/40/18 is more along the lines of what you want.

You guys are awesome. Thanks for the acknowledgment. Sorry for not making the question clear looking at the photo I actually want exactly how the 215 sits. Question is can I put 215 all around being that my rim size are all the same? And if I do run 215 on the rear I sometimes get a heavy foot would it be safe at high speeds? Corners? Etc. Hmm 225 is not too bad either thank you for that.

The tire sizing you should choose should be based on what wheel specs you're running. I always say that a good rule of thumb is that you don't want to run more stretch than you have to.

Don't count on getting much traction from a 215 rear though. With a 335i, you'll spin tires easily. Some people have problems getting 265 and 275s to hook up.

I completely agree. Only run a stretched tire if you need to stretch. If your current setup does not require it then it will look off and ruin your performance for no reason.

Now I know. I might go with 215/40 than.


Silly me. I should have known. Well, there goes the power.

Yup. 215/40/18s aren't going to be much good on a 335i for performance.

No point in stretching tires just because. As others stated, performance will suffer.
