i need some confirmation before i pull the triggger. can i put 245/40 and 275/35 on my car. i have a 07 530i non-sport. i know the manual says 245/35 and 275/30. just wondering if i could go with a more meatier tires. the wife drives the car from time to time but she doesnt care about the wheels as much as i do. also, if i can, what would be the effect as far as handling/ride comfort goes. thanks everybody!

Id stick to the recommended 245/35/19 and 275/30/19, those sidewalls are thick enough for adequate rim protection. if you were to go with even thicker sidewalls, if anything you risk chances of rubbing, but it will also depend on the offsets of the wheels.

I'm wondering the same thing. I just picked up some M5 wheels - noticing that the manual gives different sizes for 19" wheels than Tire Rack does for stock M5 fitment (255/40-19 front & 285/35-19 rear). Which way should I go? I'm not worried about the wheel getting dented more than ride quality degrading with a slightly lower profile. But it looks like the M5 fitment would increase the tire diameter as well, which would put my speedo off and maybe affect power.

If you have a non M5 E60, you cannot run the M5 tire sizes without rubbing. It is fine to use the 166s but put 245/35/19 (front) and 275/30/19 (rear) tires on.

i really dont know the offsets for the wheels. its the 125 style. so bottom line is go with the recommended tire size? what do you mean adequate for rim protection? adequate for regular driving even for some really messed up roads?

anybody else got these tire setup? or have tried and changed it to the recommended because of some reason? i just wanna make sure before i try to buy some tires this weekend.

A 245/40 on a non sport car "shouldn't" rub. You might have to just try them out.

only thing you can go for shure is 285/30/19 on rear, front 245/35/19 is max with no spacers.

so max i can go on the fronts are 245/35 and max on rears are 285/30? even giving into consideration that im a non-sport e60? cause i see some people here running with the 245/35 and 275/30 setup with their sport e60, just wishing that i could go a little bit thicker sidewall since im a non-sport.

thanks for the advise everybody. seems like imma go with with the recommended 245/35 and 275/30.

contacted atillathetom's contact for tires, he is willing to let me give it a go for 245/40 and 275/35. if i have any problem with it, i will just bring it in and hes gonna put 245/35 and 275/30 on.

on last question, would i need to do alignment after this wheel swap? thanks again everybody for your replies.
