Thanks for your help guys. I was struggling to find something suitable for that size. I'm more fussed about traction to be honest rather then width. Ones I got on now are great off the road but very much useless on road specially in wet.
You will be fine with these tyres, 42mm is very suitable for even an MTB rim. They are semi slick with more aggressive edges that will provide grip if you are ever on loose surface. https://www.planetx.co.uk/i/q/TYCLSUSHT6/clement-strada-ush-tyre-650b
looking at halfords website the carrera vengeance comes with Kenda 27.5 X 2.10. thats a average normal tyre size the one you have posted a link to is a very thin 27.5 x 1.75, and i don't even know if they would fit on the rim because they are so narrow. @umar88 the Carrera Vengeance Mountain Bike you have i would stick with tyres around the 2.0 to 2.2, if your not using it for off road use like i.e (going in the forest,red route,blue route's) then you could get some tyres that are not as aggressive and as so they wont have as much drag, so a semi slick type tyre... if you do look at a more narrow tyre like a 1.8 width then just remember when you go over bumps or up/down pavements it will feel more bumpy this is because the narrow tyre has less air volume and not as much to cushion the bumps. this is why i advised a 2.0 - 2.2 tyre
Umar88, I think these may be suitable, however, they are £24.99 per tyre + P&P. Can anyone else confirm? https://www.planetx.co.uk/i/q/TYPANPASPT650B/panaracer-pasela-pt-folding-tyre—275x175—650bx42c—tan
I've got Carrera vengeance with 27.5" tyres. I want to put thinner road or hybrid sort of tyres. Anyone know of any good price on them. And is it 27.5 same as 650b or something
