255 55 R19 tyres
255 55 R19 is a heavy-duty size, and in our experience it is fitted almost entirely to larger SUVs and 4x4s that need to carry weight without losing composure at motorway speed.
Our fitters see 255/55 R19 tyres regularly on the Land Rover Discovery 4, the Jaguar F-Pace, the Lexus NX and the Jeep Commander, and it sits within our wider 4x4 tyres range. Fitting is included in every price we show.

What the 255/55 R19 tyre size actually means
That string of numbers might look baffling but is, in fact, easy to decode. The first three numbers tell you that the width of the tyre is 255mm. The next pair gives you its aspect ratio, which simply means the height of the sidewall from rim to tread expressed as a percentage of the width. Here, 55% of 255mm equals 140.25mm. The letter describes the tyre's construction which in this case is 'R' for radial. You might also see B for bias belt and D for diagonal. The last two numbers denote the wheel's diameter, 19 inches. The mixture of metric and imperial measures may seem odd but that's the way it's done throughout the industry.
You will also see the same size written as 255 55 19 on invoices and listings, which describes exactly the same tyre. If you are not sure what is on your car, the size is moulded into the sidewall in raised lettering, and our team will read it off for you at any Protyre garage.
What are 255 55 R19 all terrain tyres suited to?
Tyres of this size are robust and belong to the group described as 'all terrain'. Ideal for 4x4s, they are designed for consistent, safe, high performance throughout the year and very suitable for winter driving. Be aware, however, that even the most durable tyres will suffer from tread wear so you should carry out regular checks. Also in a 255/55/R19 tyre pressure is very important, not only for fuel efficiency but for safe handling.
In practice that means larger tread blocks and a stronger casing than a standard road tyre, which is what lets a heavy vehicle deal with wet grass, gravel and a rutted farm track without the tread cutting up. The trade-off is a little more road noise, and it is the most common thing customers ask us about after a first set. Our qualified fitters will set your pressures to the plate figure for your vehicle rather than a generic number, which matters more on a tall 55-profile sidewall than most drivers expect.
255/55/19 tyres for every budget
An all-terrain tyre such as the 255/55/R19 needn't break the bank. Our range includes highly-regarded names such as Pirelli as well as well-made budget options from the likes of Falken and Bridgestone.

Book a free tyre check and our team will measure your remaining tread against the UK legal minimum of 1.6mm across the central three quarters of the tread, and tell you honestly how long you have left. If you want to compare wet grip, fuel economy and noise before you commit, tyre label information explains what each rating means, and our help and advice section covers day to day care. You can find your nearest garage or browse all tyre sizes if you are buying for a second vehicle.
Frequently asked questions
Because this is an SUV and 4x4 size, most of what we hold in it is built for year-round road use with some rough-surface capability. The bulk of the range is 255 55 R19 summer tyres, which use a harder compound that stays smooth and fuel-efficient and gives its best grip once temperatures settle above roughly 5 to 7 degrees. Sitting alongside those are 255 55 R19 all season tyres, a middle-ground option that keeps working through colder, wetter spells without needing a swap twice a year. Dedicated winter and run flat versions of this size are stock-dependent, so ask your local garage what is currently available rather than assuming.
Yes. Every all terrain tyre we sell is a road-legal, E-marked product built to the same standards as a road pattern, and it has to meet the same 1.6mm minimum tread depth. The distinction that matters is between all terrain and mud terrain: all terrain patterns are designed to spend most of their life on tarmac, which is why they are the sensible default for a 4x4 that does the school run five days a week and a green lane at the weekend.
Enter your registration or postcode in the search block above and we will show you what is in stock and which local garages can fit it, with dates you can book there and then. Many sizes can be fitted the same day. If you would rather talk it through first, particularly if you are choosing between an all terrain and a road pattern, call in and one of our fitters will walk you through the options for your vehicle.
