Exploring the Smallest and Biggest Tire Sizes for the 2018 BMW M4
When it comes to the 2018 BMW M4, tire selection plays a pivotal role in performance, handling, and overall driving experience. While the stock sizes provide a solid foundation, many owners are curious about the smallest and largest tire options available. Additionally, feedback from forums and owner experiences can guide you toward the best tires for your M4. Let’s dive into the details.
Stock Tire Sizes Recap
Before we explore the extremes, let’s quickly recap the stock tire sizes for reference:
- M4 Coupe: Front 255/40 R18, Rear 275/40 R18
- M4 Convertible: Front 255/40 R18, Rear 275/40 R18
- M4 GTS: Front 265/35 R19, Rear 285/30 R20
Smallest Tire Sizes
For those looking to downsize, the smallest tire options typically come from aftermarket brands or specific performance tire lines. Owners have reported using:
- Front: 245/40 R18
- Rear: 265/40 R18
These sizes are slightly narrower than the stock options. While they can provide a softer ride and lower rolling resistance, they may compromise cornering stability and grip, especially during aggressive driving. Owners on forums have noted improvements in ride comfort but warned of reduced performance on the track.
Largest Tire Sizes
On the flip side, if you want to maximize grip and improve handling, larger tire sizes can be beneficial. Many M4 enthusiasts have found success with:
- Front: 275/35 R19
- Rear: 295/30 R20
These sizes offer a wider contact patch, which translates to better traction and cornering capabilities. However, fitting larger tires may require modifications to the wheel wells or suspension adjustments to avoid rubbing. Owners have shared mixed reviews, with some praising the enhanced performance while others caution about the potential for increased road noise and a stiffer ride.
Best Tires Based on Owner Feedback
Choosing the right tire goes beyond size; tread design and rubber compound matter too. Here are some of the best-rated tires according to owner feedback and forum discussions:
- Michelin Pilot Sport 4S: Widely regarded as one of the best performance tires. Owners rave about its grip in both dry and wet conditions, making it a top choice for spirited driving.
- Continental ExtremeContact Sport: Known for excellent handling and responsiveness. Many owners appreciate its balance between performance and comfort.
- Pirelli P Zero: A favorite among M4 owners for its high-speed stability and cornering performance. It’s often recommended for track days.
- Bridgestone Potenza S-04 Pole Position: Offers a great blend of grip and tread life. Owners have noted that it performs well in both daily driving and aggressive conditions.
Considerations for Choosing Tires
When selecting tires for your M4, keep these factors in mind:
- Driving Style: If you plan on taking your M4 to the track, prioritize tires that excel in grip and handling.
- Weather Conditions: Consider all-season tires if you live in an area with variable weather. Performance tires may not perform well in snow or ice.
- Budget: Performance tires can be pricey, but investing in quality can save you money in the long run through better tread life and performance.
- Fitment: Ensure that the tire size you choose fits your wheels without rubbing. It’s often wise to consult with a tire professional or check forums for fitment experiences.
In the world of the 2018 BMW M4, tire size and selection can significantly impact your driving experience. Whether you opt for the smallest or largest sizes, make sure to consider feedback from fellow owners and your specific driving needs.
