The 2016 BMW M235i sits in the sweet spot of BMW's compact performance tradition, blending modern turbocharged power with the balanced proportions and rear-wheel-drive character that enthusiasts look for in a small sport coupe or convertible. Tire fitment matters here because this car uses a staggered 18-inch setup, with 225/40R18 up front and 245/35R18 at the rear. That means the real choice is less about finding one universal size and more about matching the correct front and rear tires, construction, and rim compatibility. Available options center on blackwall radial performance tires from BFGoodrich and Nitto, making this page especially useful for owners replacing worn tires or confirming fitment on an unmodified car.
Which Tire Size Is Right for The 2016 BMW M235i
The 2016 BMW M235i uses two primary tire sizes, both in radial construction on 18-inch wheels. The key first step is confirming whether the tire is for the front or rear position, since this BMW uses a staggered setup rather than the same size at all four corners. Once that is clear, the decision becomes comparing the available performance-oriented tire choices within the correct size.
Fit(s): Base, Base Front, Convertible, and Convertible Front
Construction: Radial|Rim: 18 in
225/40R18 is a modern metric radial size in which 225 identifies the section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 18 is the wheel diameter in inches. On the 2016 BMW M235i, this size is used at the front, where maintaining the correct fitment helps preserve the car's intended staggered balance. Available choices in this size include blackwall radial tires from BFGoodrich and Nitto across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This is the size to evaluate when replacing the front tires or refreshing a matched front axle set.
245/35R18 is also a modern metric radial size, with 245 representing nominal section width in millimeters, 35 indicating a lower-profile sidewall, and 18 identifying the wheel diameter. On the 2016 BMW M235i, this size is used at the rear, where the wider footprint is part of the car's staggered tire arrangement. The available product selection in this size centers on blackwall radial performance fitment, including BFGoodrich g-Force Phenom T/A. Choosing this size means confirming rear-wheel application and making sure the tire matches the car's existing wheel width and overall setup before installation.
Fitment on the 2016 BMW M235i is straightforward once the exact configuration and wheel position are identified. The covered sub-models follow the same staggered pattern, so checking whether the tire is for the front or rear matters more than trim differences.

2016 BMW M235i Base
The 2016 BMW M235i Base uses the same 18-inch radial tire fitment family as the rest of the covered lineup, with the front and rear positions split by size. Tire selection should focus on preserving the intended staggered setup and choosing the right performance-oriented radial in the correct axle position.
The 2016 BMW M235i Base Front uses the 225/40R18 radial size. That makes front tire selection a matter of comparing the available blackwall performance tires in that size while confirming wheel width and keeping the front-to-rear stagger intact.
The 2016 BMW M235i Base Rear uses the 245/35R18 radial size. Rear tire replacement should stay focused on that wider 18-inch fitment so the car retains its proper staggered arrangement and the tire remains compatible with the rear wheel setup.
The 2016 BMW M235i Convertible follows the same staggered 18-inch radial fitment pattern as the coupe. Tire choice still comes down to selecting the correct front or rear size first, then comparing the available tires by series, brand, and wheel-width compatibility.
The 2016 BMW M235i Convertible Front uses the 225/40R18 radial size. That keeps the front fitment decision simple: use the correct 18-inch front tire size and compare the available blackwall performance options that suit the wheel and intended road use.
The 2016 BMW M235i Convertible Rear uses the 245/35R18 radial size. Choosing a rear tire means staying with that dedicated rear fitment and checking that the selected tire matches the wheel width and overall staggered configuration already on the car.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 2016 BMW M235i?
The 2016 BMW M235i uses a staggered tire setup with 225/40R18 at the front and 245/35R18 at the rear. Both are radial tire sizes mounted on 18-inch wheels, so this car does not use one universal tire size at all four corners.
That matters because front and rear tires are not interchangeable just because they share the same rim diameter. Before replacing tires, confirm whether the car is a base or convertible configuration and then verify whether the position is front or rear, especially if the car has seen wheel changes or prior tire substitutions.
What size rim does a 2016 BMW M235i use?
The primary tire fitment for the 2016 BMW M235i uses 18-inch rims. Both 225/40R18 and 245/35R18 are built around an 18-inch wheel diameter, which keeps wheel diameter consistent even though the front and rear tire widths differ.
Wheel diameter is only one part of the fitment picture on this BMW. Front and rear tire products also carry different rim-width compatibility ranges, so it is worth confirming actual wheel width before installation, particularly on a car with aftermarket wheels, previous tire changes, or a setup that may no longer match the original staggered arrangement.
Why does the 2016 BMW M235i have more than one tire size?
The 2016 BMW M235i uses more than one tire size because it is fitted with a staggered setup: a narrower 225/40R18 front tire and a wider 245/35R18 rear tire. This is common on performance-oriented rear-wheel-drive cars that separate front and rear fitment roles.
For the owner, that means tire replacement starts with position, not just model name. The front and rear tires should be matched to the correct axle, and any change in tire brand or series should still respect the staggered sizing, wheel-width requirements, and available clearance so the car's overall balance is not unintentionally altered.
Choosing the Right Tire
What should I consider when choosing a 225/40R18 tire for a 2016 BMW M235i?
A 225/40R18 tire for a 2016 BMW M235i should be chosen as a front-position tire, since that is where this size belongs in the car's staggered setup. The available choices are radial blackwall performance tires, with options from BFGoodrich and Nitto and several distinct tire series in this size.
The most useful comparisons are wheel-width compatibility, load specification, and the overall character of each tire series rather than appearance differences, since the available sidewall treatment is blackwall throughout. Keeping the front size correct also matters if the goal is to preserve the intended relationship between steering response up front and the wider rear fitment.
What brands offer tires for the 2016 BMW M235i?
The available tire brands for the 2016 BMW M235i are BFGoodrich and Nitto. BFGoodrich appears in both fitment sizes, while Nitto is available in the 225/40R18 front size, giving front-tire shoppers a broader range of product comparisons than the rear size currently offers.
Brand choice should still come after confirming the correct axle position and tire size. On this BMW, the front and rear tires serve different roles in the staggered setup, so the better comparison is often within the correct size first, then across tire series, rim-width range, and load specification rather than choosing by brand name alone.
What tire series are available for the 2016 BMW M235i?
The 2016 BMW M235i is served by several tire series in 225/40R18, including BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. In the 245/35R18 rear size, the available series shown is BFGoodrich g-Force Phenom T/A.
That means front-tire replacement offers the widest product comparison, while rear fitment is more focused. For owners replacing all four tires, it is worth deciding whether the goal is a matched series front to rear where possible, or simply selecting the correct size and compatible specifications for each axle within the available product range.
Restoration & Appearance
Does correct tire fitment matter for a 2016 BMW M235i restoration?
Correct tire fitment still matters on a 2016 BMW M235i even though it is a newer enthusiast car rather than a traditional restoration-era vehicle. The car's staggered 225/40R18 front and 245/35R18 rear setup is part of its intended presentation, so keeping those proportions in place helps preserve the look and stance owners expect.
Appearance alone should not drive the decision, though. A restoration-minded owner should also confirm wheel width, tire construction, and whether any previous owner changed the wheels or suspension, because modern performance BMWs can look similar while using different setups. The best visual result usually starts with correct sizing before any brand or series preference.
How does tire construction affect the appearance of a restored 2016 BMW M235i?
On the 2016 BMW M235i, tire construction is straightforward because the primary fitment is radial in both front and rear sizes. That keeps the appearance close to the car's original era and design language, with a low-profile modern performance look rather than the taller sidewalls associated with older collector vehicles.
Visual differences here come less from construction changes and more from maintaining the proper staggered proportions and choosing a tire that suits the 18-inch wheel package. Since the available products use blackwall sidewalls, the main appearance decision is really about preserving the car's intended modern stance instead of chasing a vintage-style presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 BMW M235i?
Yes, modifications can affect tire fitment on a 2016 BMW M235i even when the original tire sizes are known. Aftermarket wheels, suspension changes, spacers, lowering, or alignment changes can all alter how a 225/40R18 front or 245/35R18 rear tire sits relative to fenders, struts, and steering components.
That is why the actual wheel width and overall setup should be checked before ordering replacement tires, especially on a used performance car. A size that belongs on a stock M235i may still need closer clearance review if the car has been modified, or if the current wheels no longer match the dimensions associated with the original fitment.
What should I inspect before driving a 2016 BMW M235i on new tires?
Before driving a 2016 BMW M235i on new tires, inspect tire pressure, wheel condition, valve stems, and the basic seating of each tire on the rim. It also makes sense to confirm that the correct 225/40R18 front and 245/35R18 rear sizes were installed in the proper positions on the car.
A short visual clearance check is worthwhile before normal road use. Turn the front wheels lock to lock and look for any rubbing points, then check the rear for fender or suspension clearance, particularly if the BMW has aftermarket wheels or altered ride height. Early inspection can catch fitment issues before they become tire wear or handling problems.
How often should tires on a 2016 BMW M235i be inspected?
Tires on a 2016 BMW M235i should be inspected regularly rather than only at replacement time. On a performance-oriented car with a staggered setup, frequent checks for pressure loss, uneven wear, cuts, punctures, and sidewall damage are especially important because front and rear tires do different work and will not wear in exactly the same way.
A quick inspection before longer drives is a smart habit, and seasonal checks are useful even on lower-mileage cars. Owners should pay close attention to aging, shoulder wear, and any change in ride feel, since a modern low-profile 18-inch tire can show damage or wear patterns that are easier to miss than on a taller sidewall tire.
