Tire Wrong? Wheels M240i 405M

[RuthHimmic]

Apologies for my previous attempts to navigate other discussions, as the technical jargon used therein has proven to be rather perplexing and has left me feeling disoriented.

The car remains in its original basic configuration, without any modifications or adjustments made. I have installed a set of 19-inch M performance wheels on my vehicle. The front is measured at 7j, while the rear is measured at 8j. The front tires have a size specification of 225/35, while the rear tires have a size specification of 235/30. The rear wheel has incurred damage on two separate occasions and has undergone repairs. It is now necessary to cease further attempts at repair and proceed with the replacement of the wheel. Very well.. However, by doing a thorough examination and researching other sources such as eBay, it seems that the majority of rear tires are equipped with a size specification of 255/35.

If I were to make the decision to purchase a pre-owned wheel, I would need to consider whether it is more appropriate to mount my existing 235/30 tire on it, or alternatively, replace my other tire (which is scheduled for replacement in the near future) with a 255/35 tire.

I like the understated aesthetic appeal of the low profile style, but acknowledging the challenges it presents in daily life.

Alternatively, I am seeing more convenience in locating the 8.5J wheels. However, I am uncertain about the compatibility of my 235/30 tires with these wheels.

The division of 245 by 30.

The rear wheels of the 3 series will have a width of 8.5 inches, with a tire aspect ratio of 30, resulting in a tire size of 255/30.

I appreciate your response. The notion I had in mind aligns with your statement, since locating an 8J variant is like to searching for a needle in a haystack. However, I did manage to uncover an 8J model, which also has a tire, and shares the same width of 255 as the 8.5J models. I anticipate the tire size to be 8.5J, but, I was surprised to find it to be 8J, which significantly deviates from my desired width of 235. Consequently, I am curious as to whether the discrepancy is in their tire selection or mine, and which option would be more advantageous to pursue.

It may be advantageous to do a search using the component number as a filtering mechanism in order to exclude wheels that do not meet the specified criteria.

Although I cannot be certain, the value of 255 seems to be accurate in my understanding.

It seems that the dimensions of the automobile are not suitable in several aspects. It is expected that cars with a length of 2 meters would possess front wheels with a width of at least 8J and rear wheels with a width of 8.5J. Additionally, the tires should ideally have measurements of 235/35 for the front and 255/30 for the rear. The described specifications resemble a configuration often used for winter driving conditions.

The use of a relatively narrow tire, such as a 7.5 j, on a vehicle with a considerable amount of power seems to be imprudent in my perspective.

It is important to exercise caution about the authenticity of some products. In the case of BMW, it is worth noting that they did not manufacture an 8.5" wide wheel in a 19" size. Consequently, it is quite probable that the items available for purchase on eBay are replicas or duplicates.

To clarify, the M240i equipped with Style 405M alloys is:

The wheel specifications for the given part number, 36116796220, are as follows: the wheel size is 19x7.5J with an offset of ET45. The tire size associated with this wheel is 225/35r19.
The specified wheel has dimensions of 19x8J with an offset of ET52, and it is paired with a tire size of 245/30R19. The part number associated with this wheel is 36116796221.

[dontito]

Which specific model are we referring to? Is the discussion limited to the M240i model? Because my 19-inch alloy wheels have a rear width of 8.5 inches, which is the standard size.

Could you maybe provide more context or clarification on "Style 405"? Could you please provide the make and model of the automobile, as well as its manufacturing year?
