Tyre size:
What tyre size do you require?
The exact size of a tyre can be found on its sidewall.
The following chart shows you how to read a tyre size.
1. Overall tire width in mm
2. Ratio of tire height to tire width in%
3. Tire design: ''R'' = radial tires (widely used), ''D'' or ''-'' = diagonal tires (rare)
4. Required rim diameter for this tire in inches
5. Key figure for tire load capacity
6. Key figure for the permissible maximum speed (speed index)
7. Motorcycle tire identification, tires only approved for motorcycles
8. DOT labeling
9. Date of manufacture of the tire (week of production / year of production)
 
/
SPEED INDEX:
The speed index indicates the maximum speed intended for the tyre. Up to this value, the manufacturer guarantees optimum operation with the appropriate tyre pressure. The maximum speed allowed for this vehicle is given in the vehicle owner's manual; this information can be used to select the appropriate speed index for the tyre. The speed index is the last mark on the sidewall of the tyre.

28.08.2023 from Daniel Revez
Good tyres with an excellent ratio wear/grip. I´m very satisfyed after 17.000kms, both front and rear tyres still have rubber to burn (about 3k to 5k km)
30.12.2022 from Paul Haffenden
Very positive Got a lot of people talking for an old bike they found it hard to keep up on windy roads
20.07.2020 from Hector Macdonald
Front tyre tested. Tyre performs well on dry road and dry gravel trails. Performs ok on wet roads under steering and breaking .A lot better in this regards than the K60 I had on the front before. Tyre is not great on wet grass and slides easily and with little warning. The Tourance is hopeless under any form of mud and wet rock. I would consider this tyre a 90 on road 10 Off road tyre.
07.10.2018 from DS
Good tyre although the design is getting a bit old and there are newer models. Good dry and average wet grip. Average performance on gravel & shale. Its not a full off-road tyre. It is possible to fit the tubed version yourself with tyre levers although the sidewalls are very stiff.

Absolutely fantastic, been to a number of muddy motorcycle rallies this year and these tyres have made a huge improvement navigating the muddy fields as well as being great road tyres
29.12.2021 from Dorin Claici
I am very pleased with the stability and comfort of these tyres. Although my main driving is on asphalt I have also taken my bike off road on a number of occasions and I have to say that the tyres have performed very well. My opinion is that these tyres would offer you a comfortable and safe ride on dry and wet tarmac but would also help you on the Off-road adventures. Good 70/30 reliable tyres

14.05.2021 from Phil
I bought the Pirelli Night Dragons in November 2020 to replace the original Harley Davidson American Dunlops, which had zero grip in the wet and were squared off. I live on the Isle of Wight, which has a mix of fast single carriageway roads, urban roads, and windy country lanes. The road surfaces are variable and often wet, muddy or leaf covered. As I'm not a stereotypical HD rider, I need a tyre to allow me to ride throughout the year and not just when it was dry and sunny. My mileage has been restricted due to the Covid lockdown but I have been riding more of late and feel much more confident with the Pirellis, albeit I have to remember I'm riding a behemoth of a bike which still slides over wet manhole covers etc. Overall a good purchase and I would recommend them to anyone seeking to replace their original HD tyres, and who isn't too bothered about not having the "HD" symbol on the sidewall!.

Tiger 1200 Oem tyres , very good all round tyre with lots of confidence in gravel, mixed roads and forest tracks, front tyre is not happy in the mushy wet grass centres of the tracks. Very committed road use shows no issues, running water on roads is no issue and surprisingly you use the whole tyre on the rear whereas on a gsa 1200 you don’t seem to lean as far. In general 8o/20 and 70/30 tyres that actually work off road are rare, most clog up and the front behave like you are on ice, this one is better than the Michelin anakee and Dunlop offerings , a little noise but you wear ear plugs anyway so it’s not an issue. Would buy again and to reconfirm if you really use the bike hard on road you will have no issues against a dedicated road tyre .

29.07.2024 from Mick Skeen
The rear tyre 150/70/17 needed replacing after 3000km. The photo below shows the tread depth compared to a 4mm spoke. Tread depth is about half the spoke, 2mm. This is very poor performance for a supposedly quality tire. I previously had a Shinko rear tyre and completed 8700km two up highway riding. The shinko on the front has completed 9800km and still good. I have gone back to a Shinko.
