MTB tyre change to 700C

[jyes1970]

Hi all, Is it possible to change my current wheel 27.5''X2.0 tyre size to 700C

 

[si_c]

depends on the size of tyre you're looking to fit, but the question is why are you looking to do this?

 

[vickster]

Maybe s/he is looking for more road going tyres, to replace knobbly mountain bike ones?
There should be something available in 27.5 size?

Edit: First change the wheels! Then choose tyres to fit new wheels. You can fit new wheels, assuming disc brakes and clearance (vertical). Latter NB: 27.5 plus 2" tyre is similar diameter to '700c' wheel/'road' tyre combo (+20mm) so likely OK.

That's what I was thinking, perhaps I could have phrased it a bit better... I'd not had any coffee at the time of replying, two cups in now

Not quite sure what asking here, take more coffee!
If you're asking if a 700c tire will fit on your current 27.5 wheels, no it won't!
The bead seat diameter of a 27.5/650B wheel is 584mm.
The bead seat diameter of a 700c/29" is 622mm.

 

[I like Skol]

Simple answer = NO.

29" mtb wheels can accept a 700 tyre. 27.5" wheels are too small.

Let's be fair to the OP: read their post (and made the same mistake - have edited my post).

The OP has used their tyre size to describe the wheels they have: but the question is: 'it possible to replace my 27.5 tyred wheel with a 622 rimmed wheel?'

 

[vickster]

Why though? Wouldn’t changing the tyres be easier and cheaper?
From the thread title, presumably it’s an MTB?

 

[Ajax Bay]

Ours not to reason why, . . . ours just to do and . . . answer the question.
Can I fit a new cassette with a larger cog? Why? How about fitting a smaller chainring?

I went the other way from 29” to 27.5” as it allowed me to up my cadence to a more comfortable rate (90-100rpm) for me, I don’t like slow 60-80rpm.

Does the OP mean 650B wheels found on small ladies and large youth bikes perhaps, in which case provided the tyre will fit the internal diameter of the rim then 650b road tyres would work.

 

[vickster]

oh I do hope the OP returns to clarify!

I don't know how people do that 65 is about my max

I always assume it's a prerequisite of the forum to answer a question with several other questions, although in some cases it is necessary!

I went for the 'assumptions' rather than 'questions' route, but I empathise with your prerequisition.
