I am purchasing a set of vmr's for my 335xi. The measurements are 19x8.5 et40 and 19x10 et25. I was wondering what the best tire size options that I have are?

The car is not currently lowered but I do plan on eventually installing springs or coils.

Okay so I came across a list that either 235/35/19 or 225/35/19 could work for the fronts, what are the differences in either of these sizes and which would be better to use?

VMR has nice wheels. Pics of my setup might help you visualize your offsets.

I'm running:
Apex EC-7 wheels and PSS tires:
245/40-18 x 9 et 31
285/35-18 x 10 et 43

I might try 255/295 when I'm due for new tires. My car is a LCI, therefore my rear et43 would be the same as et35 on your car. 265's like Forever Fly said would probably be max width. Also with 10" rims and only 255's or 265' would give you the stretched look. Pan on rolling your fenders with an et25.

You need to be within 1% of the rolling diameter of the tires because you're an X Model. 235/35 and 265/30 or 225/35 and 255/30. Other members who have tried 225 and 265 have experienced issues with their transfer case because it's slightly above the 1% range. I would not recommend 225/35 and 255/30 because it would be an unnecessary stretch for your fitment, especially the fronts. Unless you plan on dumping your car and running spacers in the front because those offsets are pretty weak for stretched tires.

Hi, has anybody tried to use 245/40/18 & 275/35/18 for their 335xi?

I would like to put them on my OEM 18 inch wheels.

currently running 245 35 19 and 275 30 19 on my 335

Finally put the wheels on and am so happy with how it looks. I went with 235/35/19 and 265/30/19.

Now the problem is I went with sport tires in the front and winter in the rear of two different tire companies and I feel some feedback when shifting gears almost like a transmission slip.

I thought that since I got the right sized tires it would be okay but now Im thinking that since i purchased two different types of tires from two different companies that it may throw off the 1% rolling diameter difference. Anyone have an opinion or experience with this problem?

40 in the front and 25 in the rear is a pretty big offset difference, not that it matters for rolling diameter/compatibility. I feel like I can see it in the pictures, do you like the way that looks or are you planning to kick the front out some more. looks like you have plenty of room.

You thought wrong. And don't let the dealer see that. They will surely blame any and all transfer case issues on the mismatched brands. It's not worth the risk in my opinion. Hopefully it doesn't cause any issues but it certainly can.

Yep, that can cause an issue. What tire models did you buy?

Also, are you sure you have winter tires on the rear? It doesn't look like it...

Careful. 225/35/19 paired with 265/30/19 is not above the 1% range. In many tires, it's much closer than 235/35/19 paired with 265/30/19, such as the Hankook V12, Michelin PSS, and Kumho Ecsta. Continental DW and DWS are an exception. There has been some discussion about whether having a smaller tire upfront compared to the rear, which a 225 and 265 combo will give you, and whether that can cause issues, but I'm not sure if that's been proven or not. There are people running 225/35/19 with 265/30/19, including me, that have had zero issues.
