The Turanza EL400 RFT is Bridgestone's Standard Touring All-Season self-supporting run-flat replacement tire developed for Toyota Sienna* minivans originally equipped with run-flat tires. The Turanza EL400 RFT is designed to combine temporary extended mobility for a distance of at least 50 miles at up to 50 mph even after a puncture has allowed complete air pressure loss with dry, wet and wintertime traction, even in light snow.
The Turanza EL400 RFT tires feature an all-season rubber compound molded into a symmetric tread design with straight circumferential grooves to balance dry and wet road traction with noise comfort and hydroplaning resistance. The tire's internal structure includes twin steel belts reinforced by spirally wrapped nylon to blend high-speed durability with uniform ride quality. The structure of the Turanza EL400 RFT features Bridgestone Side Support Run-Flat technology-reinforced sidewalls specifically tuned to temporarily support the vehicle after a puncture causes complete loss of air pressure.
*The P225/60RF17 99T-sized Turanza EL400 RFT developed for Toyota Sienna minivans originally equipped with run-flat tires feature Bridgestone's 3rd generation run-flat tire (3G RFT) technology.
EU Tyre Label and Efficiency Classes
The European Union has introduced the EU Tyre Label by Regulation (No. 1222/2009) identically and bindingly for all EU member states. It applies to passenger car tyres, light commercial vehicle tyres and heavy commercial vehicle tyres produced after 01.07.2012.
Three different areas are tested: rolling resistance, wet grip and the rolling noise the tyre makes on the road.
The following are not affected by the EU Tyre Label: retreaded tyres, professional off-road tyres, racing tyres, tyres with additional devices to improve traction such as spiked tyres, T-type emergency tyres, special tyres for fitting to vehicles first registered before 1 October 1990, tyres with a maximum authorised speed of 80 km/h, tyres for rims with a nominal diameter of 254 mm or less or 635 mm or more.
With this regulation, the European Union is pursuing the goal of promoting economic and ecological efficiency in road traffic as well as increasing road safety on the one hand, and on the other hand, granting consumers more product transparency and at the same time serving as an active decision-making aid.
Already during the incorporation, experts criticise the fact that the EU Tyre Label unfortunately only shows a few product characteristics. Apart from rolling resistance, wet grip and rolling noise, which are the main focus of EU tyre labelling, tyres have much more important and safety-relevant product characteristics, such as aquaplaning properties, driving stability, service life, braking properties on dry and wet roads, behaviour in wintry conditions, etc.
Tyre manufacturers point out that test results from various institutions and journals remain an important information medium for the end consumer. These tests usually focus on further safety-relevant product characteristics besides the EU standard qualifications for tyre labelling, which are always important for the final customer.
* List prices, when available, provide a net basis for calculating sales prices between tyre manufacturers and their distributors. In no event are they selling prices that are paid or customarily paid.
**Prices include VAT and delivery within mainland UK (excl. Scottish Highlands).
