The 2010 BMW 135i sits in the compact performance tradition that made the 1 Series especially appealing to drivers who wanted BMW handling in a smaller, more eager package. Whether in coupe or convertible form, this car blends modern turbocharged performance with a chassis that responds noticeably to tire choice. Tire fitment centers on radial construction, with a standard 205/50R17 setup and an 18-inch sport-package staggered arrangement using 215/40R18 front and 245/35R18 rear sizes. That means the key decision is not just brand, but also whether the car has the base wheel setup or the larger staggered sport-package combination before choosing a tire.
Which Tire Size Is Right for The 2010 BMW 135i
Three primary tire sizes apply to the 2010 BMW 135i, and the right one depends first on the exact wheel setup. The standard configuration uses 205/50R17, while the 18-inch sport-package fitment uses a staggered arrangement with 215/40R18 in front and 245/35R18 in the rear. Confirming both the sub-model and rim diameter is the first step before comparing brands, sidewall styles, or tire series.
205/50R17 is a metric radial size in which 205 identifies the nominal section width in millimeters, 50 is the aspect ratio, R denotes radial construction, and 17 is the wheel diameter in inches. On the 2010 BMW 135i, this size serves the standard 17-inch setup and keeps the fitment decision straightforward when the car has the non-sport wheel package. Available choices include blackwall performance-oriented options from BFGoodrich and Vredestein, along with an American Classic Radial wide whitewall for a more distinctive appearance. This size is the right place to start when the car wears 17-inch wheels and a square fitment front to rear.
Fit(s): Convertible w/Sport Pkg. Front and Coupe Front
Construction: Radial|Rim: 18 in
215/40R18 is a metric radial size with a 215-millimeter nominal section width, a 40-series profile, radial construction, and an 18-inch rim diameter. On the 2010 BMW 135i, this is the front tire size for the staggered sport-package setup, so it should be evaluated as part of a matched front-and-rear combination rather than as a stand-alone all-around fitment. The available product in this size is a blackwall BFGoodrich g-Force Sport Comp 2, which gives the front axle a clear performance-focused option. This size should be chosen only after confirming that the car actually uses the 18-inch front sport-package wheel arrangement.
Fit(s): Convertible w/Sport Pkg. Rear and Coupe Rear
Construction: Radial|Rim: 18 in
245/35R18 is a metric radial size where 245 is the nominal section width in millimeters, 35 is the aspect ratio, R indicates radial construction, and 18 is the rim diameter in inches. On the 2010 BMW 135i, this size belongs at the rear of the staggered 18-inch sport-package setup, pairing with 215/40R18 fronts rather than replacing them. In this fitment, the available choice is a blackwall BFGoodrich g-Force Phenom T/A, giving the rear axle a modern performance tire in the correct size format. This size matters most when maintaining the intended front-to-rear fitment balance of the sport-package configuration.
Sub-model fitment on the 2010 BMW 135i is not one-size-fits-all, because the standard wheel package and the sport-package staggered setup use different tire sizes. Checking the exact coupe, convertible, and front-or-rear sport-package position matters before choosing a tire.

2010 BMW 135i Convertible
The 2010 BMW 135i Convertible uses the standard 205/50R17 radial fitment rather than the 18-inch staggered sport-package setup. Tire selection here is mainly about choosing among available brands and sidewall styles while confirming that the car still wears its 17-inch wheels.
The 2010 BMW 135i Convertible with Sport Package uses 215/40R18 at the front as part of a staggered radial arrangement. Front tire replacement should be matched to the rear sport-package setup and checked against the actual 18-inch wheel dimensions on the car.
The 2010 BMW 135i Convertible with Sport Package uses 245/35R18 at the rear, paired with a different front size. Rear tire selection should preserve the staggered layout and is best approached by confirming both the rear wheel width and the matching front fitment.
The 2010 BMW 135i Coupe uses the standard 205/50R17 radial tire size in its non-sport configuration. That keeps the choice centered on tire character and appearance rather than front-to-rear stagger, provided the coupe still has its 17-inch wheel setup.
The 2010 BMW 135i Coupe front sport-package position uses 215/40R18 as the front tire size. Choosing this fitment means verifying that the coupe has the staggered 18-inch arrangement so the front tire remains properly matched to the rear size.
The 2010 BMW 135i Coupe rear sport-package position uses 245/35R18 in a staggered radial setup. Rear tire selection should account for the car's matching front size and wheel package so the overall fitment stays consistent with the intended 18-inch layout.
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.
Best 2010 BMW 135i Tires for Sale
Available 2010 BMW 135i tires focus on radial fitments in 17-inch and 18-inch sizes, with BFGoodrich appearing across all three sizes. Depending on the setup, buyers can compare blackwall performance-oriented series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Sprint Plus, and an American Classic Radial wide whitewall option in 205/50R17.
Common 2010 BMW 135i tire questions usually come down to identifying the correct wheel setup first, then choosing the right radial tire by size, brand, sidewall style, and intended use. The details below cover standard versus staggered fitment, product selection, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 2010 BMW 135i?
The 2010 BMW 135i uses three primary tire sizes across its different configurations: 205/50R17, 215/40R18, and 245/35R18. The standard coupe and convertible use 205/50R17, while the 18-inch sport-package setup uses a staggered combination with 215/40R18 in front and 245/35R18 in the rear.
The practical first step is confirming whether the car has the standard 17-inch wheels or the sport-package 18-inch staggered setup. A 135i that has been changed to aftermarket wheels may no longer follow the original fitment, so checking the actual front and rear tire sizes on the car helps prevent ordering the right size for the wrong wheel package.
What size rim does a 2010 BMW 135i use?
A 2010 BMW 135i uses either a 17-inch or 18-inch rim, depending on configuration. The 205/50R17 fitment uses a 17-inch wheel, while the sport-package arrangement uses 18-inch wheels with 215/40R18 at the front and 245/35R18 at the rear.
Wheel diameter is the most important thing to verify before choosing a tire, especially on a car that could have been upgraded or changed over time. Front and rear wheels should also be checked separately on staggered 18-inch cars, because using the correct diameter alone does not confirm the correct front-to-rear size relationship.
Why does the 2010 BMW 135i have more than one tire size?
The 2010 BMW 135i has more than one tire size because different versions use different wheel setups. Standard coupe and convertible models use 205/50R17, while sport-package cars use a staggered arrangement with a narrower 215/40R18 front tire and a wider 245/35R18 rear tire.
That means tire choice is tied to the car's exact configuration, not just the model name. Looking at the wheel diameter, checking whether the car has the sport package, and confirming front versus rear sizing on staggered cars will narrow the fitment quickly and avoid mixing a square setup with a staggered one.
Choosing the Right Tire
What should I consider when choosing a 205/50R17 tire for a 2010 BMW 135i?
For a 2010 BMW 135i using 205/50R17, the main considerations are correct size, radial construction, wheel compatibility, and the type of tire character you want. Available choices include BFGoodrich performance-oriented g-Force series, Vredestein Sprint Plus, and an American Classic Radial with a wide whitewall sidewall treatment.
Selection becomes more meaningful once the car's actual use is clear. A blackwall performance-style tire suits a more modern look, while the wide whitewall creates a custom appearance that changes the car's presentation noticeably. Rim-width compatibility, load figures where shown, and the condition of the existing 17-inch wheels are all worth checking before making the final choice.
What sidewall styles are available for 2010 BMW 135i tires?
Sidewall choices for the 2010 BMW 135i include blackwall and wide whitewall, depending on tire size and product. Blackwall options appear across the available 17-inch and 18-inch fitments, while the wide whitewall treatment appears in the 205/50R17 American Classic Radial.
That makes sidewall style an appearance decision as much as a fitment one. A blackwall keeps the car closer to a contemporary performance presentation, while a wide whitewall gives a much more customized look. Before choosing on appearance alone, it still helps to confirm the correct wheel diameter and the specific size required by the car's standard or staggered setup.
What brands offer tires for the 2010 BMW 135i?
Tires for the 2010 BMW 135i are available from BFGoodrich, American Classic, and Vredestein. BFGoodrich covers all three primary sizes, while American Classic and Vredestein appear in the 205/50R17 fitment for the standard 17-inch configuration.
Brand choice should be considered alongside size, series, and sidewall treatment rather than in isolation. On a standard 17-inch 135i, there is broader variety to compare, while the 18-inch sport-package sizes are more narrowly focused. Matching the tire to the car's wheel setup and intended appearance usually matters more than chasing a brand name by itself.
Restoration & Appearance
Which tire should I choose for a period-style 2010 BMW 135i?
A period-style 2010 BMW 135i tire choice usually starts with keeping the original fitment format for the car's wheel package. That means 205/50R17 for standard coupe and convertible models, or the 215/40R18 front and 245/35R18 rear staggered setup for sport-package cars, all in radial construction.
Appearance then depends on how faithful or how personalized the finished car needs to be. Blackwall tires maintain a more contemporary OEM-era look, while the available 205/50R17 wide whitewall creates a custom visual statement. Owners pursuing exact originality should compare the car's current setup with BMW-specific reference material before settling on a sidewall treatment.
Which sidewall style suits a period-style 2010 BMW 135i?
For a period-style 2010 BMW 135i, blackwall is the more natural visual fit because it aligns with the car's modern performance-era character. A wide whitewall is available in 205/50R17, but it creates a custom look rather than simply echoing the understated appearance most buyers expect from a 2010 German sport coupe or convertible.
The right choice depends on the direction of the car. A standard-wheel 135i built around a clean OEM-style presentation usually points toward blackwall tires, while a custom project may benefit from the whitewall's contrast. Since sidewall style changes the look more than the fitment, wheel diameter and the car's correct size should still be confirmed first.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 BMW 135i?
Yes, modifications can affect tire fitment on a 2010 BMW 135i even when the size looks close to stock. Aftermarket wheels, altered offsets, suspension lowering, spring changes, or body modifications can all change the clearance relationship around 205/50R17, 215/40R18, or 245/35R18 tires.
A modified 135i should be checked at all four corners before replacing tires by original application alone. Front-to-strut clearance, rear fender clearance, and steering movement are especially important on staggered 18-inch setups. Matching the correct size to the wheel diameter is only the beginning when the car no longer sits on its original wheel and suspension combination.
What should I inspect before driving a 2010 BMW 135i on new tires?
Before driving a 2010 BMW 135i on new tires, inspect the wheels for damage, confirm the correct front and rear sizes, and make sure the tires are seated and inflated properly. It also helps to look over the suspension and alignment condition, since worn components can affect how a fresh set of tires behaves.
A quick road-use check should include clearance at full steering lock, visible fender clearance, and a recheck for air loss after the first miles. Staggered 18-inch cars deserve extra attention because front and rear sizes differ. Even with the correct tire size, a bent wheel or poor alignment can shorten tire life quickly.
How often should tires on a 2010 BMW 135i be inspected?
Tires on a 2010 BMW 135i should be inspected regularly, not just when tread appears low. Monthly pressure checks, visual inspection for cuts, cracking, bulges, and uneven wear, and a closer look before longer drives are all sensible habits, especially on a performance-oriented car that can be sensitive to tire condition.
Cars that are driven infrequently still need attention because age, storage conditions, and slow air loss matter as much as mileage. A 135i with staggered 18-inch tires should also be checked by axle position, since front and rear wear patterns may differ. Catching issues early helps preserve ride quality, handling balance, and wheel protection.
