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.

14.07.2025 from Phil Duckles
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’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

Pretty good, no grip issue's

26.09.2021 from Adrian watkinson
A good all round tyre, bearing in mind it’s fitted to a low powered bike 65hp. Used enthusiastically mainly on tight twisty tarmaced single lane roads with a lot of braking, cornering and acceleration. Front almost worn out after 5k miles rear lasted 2.5k miles. The tyre looks good on this type of bike and works ok off road on reasonably hard dry tracks, not great on mud though. I prefer these tyres to metzeller Torrance tyres and will/have bought again.
28.09.2014 from ian mcclure
great tyre for money.not tried in heavy rain.got these on front and rear,transformed turn in from original tyres,michelin anakees.
16.04.2013 from Lootch67
Front not stable at speed due to very narrow profile. Good miles:cost ratio tyre.
05.09.2009 from Danny Sherman
Great tyre, wear rate a little could be better, or should I knock off the throttle a bit more ?

04.03.2019 from Tomaz
Very good milege 16k km regional roads, country trails soft offroad, very good for dualsport, noisy when cornering. Grip is good, when it goes does not slip all the way. The front tyre could have a little more braking power on pawed road and back tyre could have softer compound on sides.
28.09.2015 from steveR
This tyre last better than a TKC80 and in anything other than mud, are as good gripwise, at least on the rear! Wear suffers, even on a lightweight, with a laden bike in hotter conditions I found.
25.02.2015 from Chris Gilbert
This tyre has given me lots of confidence on and off road. There is ample grip on the rough and gives a smooth safe feel on the road.

Tyres seem good so far with no sign of ware. Slight road noise over my last tyres but nothing serious. A good compromise between off and on road. Very competitive price.

the tyre has been above expectation on the road, grip levels fine, of road when wet and muddy it has struggle compared to a full knobbly but on gravel trails it has been good.
