The Turanza 6 is quite a new addition to Bridgestone’s lineup, being introduced in 2023. Featuring the new ENLITEN technology, it should be lighter and have positive effect on fuel efficiency. In the tests, the efficiency is confirmed alongside with higher mileage. That being said, it somehow lacks the performance of other premium tyres, so we would recommend it only when the price is lower.
245/55 R19 doesn't belong to the most popular dimensions for summer tyres - there are 3 tyre models available, which can be compared to 155/60 R15, 170/60 R17, 160/60 R14. Let's break down the sizing - 55 is height of the tyre, which is calculated as 55% of the tyre width (245mm), which means the sidewall height has 134.75 mm. The wheel diameter is R19, which means it fits to a 19 inch/482.6mm diameter wheel. The total circumference of the tyre is 2362.79 mm, which is very similar to 265/70 R15(2362.48 mm), 245/60 R18(2359.96 mm), 245/50 R20(2365.62 mm), 275/40 R21(2366.88 mm), 245/65 R17(2357.14 mm), 245/70 R16(2354.31 mm), 275/45 R20(2373.47 mm). There are multiple speed indexes available for summer tyres in 245/55 R19: H(210km/h), S(180km/h), V(240km/h), W(270km/h). The same goes for weight indexes: 103, 107.
