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.

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

29.10.2022 from Lewis
This tyre is a great compromise between a road tyre and a knobbly. I can probably get another 1500km out of mine. It has squared off but still turns over OK. Grip wise you can really push on with it and spin the rear up exiting corners, you really have to push on it to make it happen and when it does its really confidence inspiring and gives great feed back. On the edge of the tyre you can feel it start to come round again you really need push it. I have mine fitted to a 1200 scrambler. And have found it fantastive for its intended use. Great tyre on road and very cabable off road. I&#39;ve been on dry Rocky green lanes and through wet slushy mud with out any real drama. Matched mine with an 80 front and its great. Only downside to my experience was the lead time for delivery from the supplier

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&rsquo;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&rsquo;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 .

Very dissapointed. Tires arrived bumpy. Front tire felt like tractor tire, shipped it back to mitas slovenia, they sent another one (less bumpy) but still bad.
16.04.2023 from Sebastjan
no complaints, the tire is more than great for the money. the handling of the motorcycle is satisfactory both in the wet and in the dry.. the rear tire lasted about 9500 km of quite wild driving in wet and dry conditions.. even on the highway over 200 km/h it is very stable.. the front tire would have lasted a few more km..

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.

This tyre is amazing, it provides dry and wet grip in abundance. It provides a wear consistentancy through the tyres life that drops very little. I also trackday this tyre and its calmness and predictability at the limit is great. I haven&rsquo;t found an all round tyre to match it yet.
13.10.2022 from Paul Church
Banking right over, this tyre gives great confidence. Got the stronger side walled tyre for my heavy 630lb BMW K bike Angel GT is super sticky! Would definitely buy again.
24.08.2022 from Andrew
Good tyre better wear than previous Bridgestone tyre with similar stopping and cornering grip

They are simply a great all round tyre. I ride all year round and on good to reasonable condition roads (you know what I mean) I haven&#39;t been able to make them slip and I ride progressively. Enjoy

21.02.2021 from Chris Charlesworth
Fitted these to my NC750X for a trip to Morocco where I knew I&rsquo;d need something with all Little off road ability (90:10 in favour of road). They replaced some Bridgestone 023s, which had been a big improvement over the standard Dunlop Trailmaxs, so I didn&rsquo;t expect much improvement. I was pleasantly surprised, especially in the wet where grip and feedback is massively improved, giving much more confidence cornering in the wet. I do around 7000 miles a year commuting in all weathers and these are the best tyres I&rsquo;ve used.
09.11.2019 from Martin
From the first time riding with the new tyres the bike was transformed, steering accuracy was fantastic and the tyre performs brilliantly in wet and dry conditions with very short warm up time. The bedding in period was not needed as I found no issues at all.

08.01.2024 from Alaedin Sadeghi
Poorly performing tyres!!! The tyres worn out very quickly within a few months of fitting. At the time of fitting the alignment was checked / adjusted by the appointed fitting workshop. So I am very puzzled as to why the tyre shoulders worn out so quickly. I took the car back to the original fitting workshop and complained. The re-checked alignment and assured me all will be good from now on. It was also checked to investigate if the tyres had correct inflation pressure. Tyre have continued to deteriorate to the extend that in the last MOT inspection, these were picked up as &#39;advisory&#39; by the MOT garage. I will stay away from this tyre vendor in future.
20.01.2021 from bushy
These are great tyres for general use - have also used them on the track at Brands and they performed fine as well. Will get them again nest time :)
20.01.2020 from Teresa Gilder
this is my first motorcycle on the road. I put new tyres on it with a recommendation from my husband. How right he was, these tyres are very good for a new rider like me. I&#39;ve used them on hot dry sunny days and also through a couple of downpours. Never had any bad feedback from them.

Have used the tyres both on road and off road. The tyres are more capable than I am as a rider therefore dealt easily with everything I have put them through with ease.
13.03.2023 from Michael
Tyres were purchased to do some green lane riding. These are very suitable for the purpose and handle as good as road tyres when in the tarmac. Only downside is that you get around 3000 miles out of a rear tyre and it&rsquo;s done!
29.10.2022 from Lewis
This tyre has been great. After initial fitting the steering was a bit strange but after 50-100 miles it felt like a road tyre. Great off road and one of the best knobbly tyres on the road. Done 10500km on the tyre, only have the tkc80 on the front. I have a 70 rocks on the rear. I believe the front will do another rear. Tyre was great but the delivery time from the provider was shocking
