I have a 2011 xdrive 335i coupe and I have decided to get BS CH-R 19x8.5 , all around just wondering what tire size I could get. I have read somewhere that 255 would work but might need to mod the front so wheels could fit, I would like to know what tire size do you guys recommend that needs no modifications?
currently I have kw v1 coilovers with
18x8.5 235/40 front
18x9.5 265/35 rear

Why after having staggered, are you planning on a square setup?

I really want 19s and to be able to make my tires last longer tire rotation, and not worry about messing up the awd.

[neverdone]

My xDrive comes with stock 19x8 and 19x9 I'm pretty sure it won't mess up your awd.

The wheel sizes available are 19x8.5 and 19x9.5, what tire size would be good? without needing to roll fenders?

[trueuro]

hey guys im new to the forum. i have an 08 328i coupe looking to run varrstoen es2's 19x9.5 19x10.5. im on stock suspension and fenders havent been rolled. what tire size do i run for nice some nice stretch and no rub or issues? any help would be really appreciated!

[Aashenfox]

Dude, don't buy a non-stagger set of CH-R, the rears are beautifully concave, it would be a shame to miss out on that. 8.5 front, 9.5 rear, and either...

225/255 (BMW recommended and should be fine without rolling rear fenders, no promises though)
235/265
235/275 (closest diameter for x-drive, but you will definitely need to roll rear fenders if you're going for the 9.5+35 CH-Rs in the rear)

I have 19" CH-Rs as my summer wheels on my pre-lci xi, with 275/30/19 in the rear and I have rolled my rear fenders.

I have 235/40/19 on an 8.5 all around

235 and 265 are the norm for staggered wheels on xdrive with a 19x8.5 and 19x9.5. No rubbing as long as you have the correct offsets.

Are you sure? That's a fair bit oversize.

[mashimarho]

The size you have is good there. I would recommend that.

[Give_Em_The_DD]

I've got 18x8 245/35 all 4 corners.


For sale if interested lol

Lol you have convinced me to go staggered again. Sorry but I have no idea about tires and I would rather not mess up the xdrive or roll fenders. and I want the rolling diameter less than 1%

would 235/40-19 fronts and 265/35-19 rears be ok because
tire rack recommends 235/35-19 fronts and 265/30-19 rears

[Aashenfox]

Tire Rack's recommendation is correct. You will DEFINITELY have issues if you upsize, as the CH-Rs have a semi aggressive offset anyway, even more so on your LCI.

235/35 front, 265/30 rear.

Although 275/30 rear will get you to almost identical diameter front and rear (with my tires, it's 0.17% difference). You may need a rear fender roll for the 275s, but it ain't nuttin, DO IT!

Ah not a fan of fender rolling but I'll think about. Also thanks so much for the help, I appreciate it!!!

Yep. Don't know why. It was my mistake for ordering them through discount tire and having them choose my sizes. Although I have no rubbing issues.

That's good news. You probably already know this, but in fact running those size tires makes your speedo pretty much dead-on, if you go by the BMW average of 7% under-reading with stock sizes.

You might need the roll even if you go 265. The CH-R 19s are only available in a fairly aggressive offset for our cars (+35 for the 9.5s). You might want to go 225/255 if you are dead set against a roll.

I've got my fingers crossed for you that even on 265 a roll won't be needed, but just let me say again, you are not doing anything bad to your car by rolling the rears, just tucking up a bit of extra metal, it really is nothing, I used to avoid it as well, it's one of those things where when you do it, you wonder what you ever had against it, lol.

now I'm undecided again maybe I'll go squared with spacers in the back.

Does different size spacers in the front and back affect the xdrive system?

With all the torque you are making, you need much more tire!

I currently run 245/285 and will go with 255/295 when my current set needs replaced. Torque + Traction = Fun!!!!

Just the outer diameter of the tire affects the xdrive system. Spacers simply space the whole wheel and tire outward, and do not have any affect on xdrive.
