The UltraGrip Performance 3 is one of the best tyres we have seen in the tests and on top of that it's top discipline is snow performance while maintaining great properties on wet, which makes it a great candidate for snowy climates.
The Alpin 6 was introduced back in 2019, but still holds up surprisingly well compared to the current competitors. It's pricey, but Michelin promises it will maintain it's performance during the whole lifespan, which is rarely tested.
The EuroWinter HS02 is one of the few affordable winter tires with good mileage and low rolling resistance. It offers strong driving characteristics, with only slight weaknesses on snow.
225/50 R19 doesn't belong to the most popular dimensions for winter tyres - there are 1 tyre models available, which can be compared to 155/60 R15, 170/60 R17, 160/60 R14. Let's break down the sizing - 50 is height of the tyre, which is calculated as 50% of the tyre width (225mm), which means the sidewall height has 112.5 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 2222.99 mm, which is very similar to 285/35 R20(2222.68 mm), 215/70 R16(2222.36 mm), 205/55 R19(2224.56 mm), 245/35 R21(2214.51 mm), 225/55 R18(2213.88 mm), 275/45 R18(2213.88 mm), 285/40 R19(2232.42 mm). There are multiple speed indexes available for winter tyres in 225/50 R19: H(210km/h), V(240km/h). The same goes for weight indexes: 100.
