Overview
The Bridgestone Turanza EL450 RFT is a premium summer touring tire designed for drivers who value security, comfort, and the added peace of mind delivered by run-flat technology. Targeted at owners of mid-size sedans, sporty coupes, and crossovers—often as original equipment on models like the Lexus ES, Infiniti Q50, and select BMW 5 Series—the EL450 RFT delivers reliable dry and wet performance for everyday driving and highway touring. Its primary focus is safety, with the ability to continue driving after a puncture, making it a favored choice for those who travel long distances or simply wish to avoid roadside tire changes. The Turanza EL450 RFT is strictly a summer tire: it should not be used in snow or freezing temperatures.

Performance: Dry
On dry pavement, the Turanza EL450 RFT impresses with stable handling and a well-balanced ride. The asymmetric tread design provides predictable cornering and solid straight-line stability, especially at highway speeds. Braking distances are competitive for the segment, and steering response is crisp enough for confident lane changes and merging. While not a performance tire, it delivers reassuring grip for everyday driving, with a slightly firmer feel due to the reinforced run-flat sidewalls. Enthusiast drivers may notice a hint of reduced feedback compared to conventional summer tires, but for most drivers the ride strikes a practical balance between responsiveness and comfort.
Performance: Wet
In wet conditions, the Turanza EL450 RFT maintains its composure. The circumferential grooves and advanced silica-enhanced compound work together to channel water away and resist hydroplaning. Wet braking is secure and controlled, and cornering grip remains dependable even in moderate summer downpours. The tire’s run-flat construction means it is slightly heavier than non-run-flat alternatives, but it does not compromise safety or everyday usability in the rain. Drivers should, however, exercise caution as with any summer tire—traction will not match that of an all-season or dedicated wet-weather tire in standing water or heavy storms.
Performance: Snow & Ice
N/A – The Bridgestone Turanza EL450 RFT is a pure summer tire. It is not suitable for driving in snow, slush, or icy conditions. Use dedicated winter or all-season tires if you require cold-weather capability.
Comfort & Noise
Despite its run-flat construction, the EL450 RFT delivers a reasonably comfortable ride for a summer touring tire. Bridgestone’s NanoPro-Tech compound and optimized tread design help absorb minor road imperfections, although some additional firmness is present compared to standard tires. Noise levels are moderate: on smooth asphalt, the tire is quiet and unobtrusive, but coarse surfaces can produce a subtle hum, typical for run-flat models. Road impact harshness is slightly more pronounced, but for drivers prioritizing run-flat security, the trade-off is acceptable. Cabin comfort remains strong, especially on well-maintained roads.
Durability & Economy
Durability is a strong suit for the Turanza EL450 RFT. The tire’s treadwear is consistent, aided by a robust construction and advanced silica compound. The UTQG (Uniform Tire Quality Grading) rating for the most common sizes is typically in the 300–400 treadwear range, with AA or A traction and A temperature grades. This positions the tire as a solid choice for drivers seeking long service intervals on summer roads. Rolling resistance is moderate—slightly higher than non-run-flat tires due to the reinforced sidewalls, but not excessive. Fuel economy is minimally impacted, and the tire is engineered to withstand potholes and sharp impacts better than many conventional touring tires. Regular rotation and proper inflation are important to maximize lifespan.
Sizes & Alternatives
The Bridgestone Turanza EL450 RFT is available in a range of 17″ to 19″ sizes, making it a common OE fitment and replacement option for premium sedans and crossovers. Popular sizes include:
- 225/50 R17 94V

Verdict
The Bridgestone Turanza EL450 RFT stands out as a dependable summer run-flat touring tire, offering everyday drivers and fleet managers added confidence without sacrificing core safety or comfort. Its dry and wet performance is well-suited to typical US summer conditions, and wear characteristics make it a smart long-term investment for those prioritizing peace of mind over maximum road feel or outright performance. The firmer ride and higher price tag are common trade-offs for run-flat technology, but for drivers who appreciate the ability to drive to safety after a puncture—and for those whose vehicles require OE run-flat replacements—the Turanza EL450 RFT is a worthy choice. Be aware of its summer-only limitation: if you drive in regions with cold winters, a seasonal tire swap is essential. Overall, this tire is best suited for those seeking a blend of safety, comfort, and reliability during the warmer months, particularly on premium sedans and crossovers where run-flat capability is either required or strongly preferred.
I see the Turanza EL450 RFT is not meant for snow or freezing temperatures. If I live in an area with occasional mild winters, do I need to swap these out each year, or can they handle a bit of cold as long as it’s not snowing?
The Turanza EL450 RFT is designed for warm weather, and its performance drops noticeably in cold conditions, even if there’s no snow. If your winter temperatures occasionally dip near freezing, it’s safer to switch to all-season or winter tires during those months to maintain grip and safety. Using summer tires in cold weather can lead to reduced traction and longer stopping distances.
Are there significant differences in road noise levels between the 17-inch and 18-inch sizes of the EL450 RFT mentioned here?
The road noise levels between the 17-inch (225/50 R17) and 18-inch (245/45 R18) EL450 RFT tires are quite similar overall. However, the 18-inch size may produce a slightly firmer ride and marginally more road noise due to lower sidewall height, but most drivers will find the difference minimal in everyday use.
How long does the NanoPro-Tech compound typically last before the grip noticeably decreases compared to other Bridgestone tires?
The NanoPro-Tech compound in the Turanza EL450 RFT is designed for longevity and consistent grip, often maintaining good performance for around 25,000 to 35,000 miles under normal driving. This is fairly comparable to other Bridgestone touring run-flats, though ultra-high-performance compounds may show grip loss a bit sooner. Proper tire care and rotation will help maximize its lifespan.
You mention these are strictly summer tires. What’s your experience driving them in unexpected cold snaps, like early fall mornings when temperatures drop close to freezing?
When temperatures drop close to freezing, the Turanza EL450 RFTs tend to feel stiffer and less grippy, especially during the first miles until they warm up a bit. They’re still safe for careful driving in dry cold, but traction on cold, damp, or frosty roads is noticeably reduced. I’d recommend extra caution and avoiding use in actual snow or icy conditions.
I see these are strictly summer tires and not meant for snow or freezing temps. Is there any risk of sidewall damage if I get caught in a sudden cold snap while still running the EL450 RFTs?
While the EL450 RFTs are built for summer use and aren’t optimized for snow or freezing temperatures, a brief cold snap should not directly cause sidewall damage. However, the rubber can become less flexible and more prone to cracking or impact damage if temperatures stay low. For safety and longevity, try to avoid driving on them in cold conditions whenever possible.
If I mostly drive long distances on highways, does this tire handle extended heat and higher speeds reliably, or should I be concerned about faster tread wear?
The Turanza EL450 RFT is built for highway use and designed to handle heat and higher speeds reliably, thanks to its summer touring compound. While frequent high-speed, long-distance driving can increase tread wear compared to city driving, this tire is engineered to maintain durability and performance under those conditions. Just be sure to monitor tread depth and maintain proper inflation for optimal longevity.
