Tyre sizes

[PinkFloyd]

Haven't changed a bike tyre in years so not too sure about sizes..... the Forza comes with 26" x 1.95 tyres. I am going to be replacing them with the Schwalbe Marathon Plus but the sizes are:

700 x 25
700 x 28
700 x 32
700 x 35
700 x 40

Eh? what size should I get to replace the 26" x 1.95 ? Can I fit a few different sizes or is there just on size you can fit?

Thanks.

700 is 28", not 26" so you need to look at the right range of tyres. The Schwalbe Marathon tyres come in 26" sizes as well, take a look at their web site here: Schwalbe UK

PS: I suspect a 26 x 1.75 would be OK.

 

[PinkFloyd]

Thanks Jeremy..... so I assume 700 is 700 millimetres? 700 / 25 = 28 so I am looking for a 650 correct? so.... 650 x 50 is the tyre I need? or a 26" x 2

Here you are Pink Floyd, at the following is the lowest price around for them, normal retail £26.99, here £17.99. In the dropdown options its 26" x 1.75" for the Forza:

AllTerrainCycles

No-one ever beats their price on these.

Thank you Flecc, I will give those a go. What do you think of these guys? Continental Cycle Tyres UK

 

[PinkFloyd]

These would be better for speed but not wide enough Continental Cycle Tyres UK

Make sure you get 26" mtb size these are different to the 650 size.

Comtinental tyres are good, and they now make an equivalent to the Marathon Plus, though I don't know which model it is.

The Marathon Plus is unique in having a thick inner puncture resistant layer which can force sharp things back out:

These are quite fast and very little different from the mainstream Continental models. Very much easier rolling than the standard cheap Kenda tyres. The difference in rolling resistance of top end tyres is quite small.

Cheers Flecc, I'm going to order a pair tonight I've been reading reports that they're a bit of a bugger to fit is this right? I've got a couple of pretty meaty crowbar type things which I managed to put a new car tyre on with so hopefully they will do the job.

I assume these tyres will also improve the range of the battery as they will offer less impedance and roll a lot easier than the stock tyres? Fascinating stuff when you think of it with each component in the chain feeding off the other.... one weak link and no matter how good the rest of the components are the performance will suffer..... I'd think tyres are probably the most important as they are in contact with the road so definitely not an area to go budget on, only the best will do here whatever the cost.

What about tyre pressures, have you experimented with these? Ezee recommend 40psi for the stock tyres.... is it the old standard of less for comfort, more for speed, or have things changed over the years? Sorry about all the questions but I find this all fascinating and half the fun in owning a vehicle is getting to know it and maintaining it.... heh, on my forum I'm used to giving the answers, I'm like a kid in a sweet shop here actually geting to ask questions.... awesome

On fitting I found they were no different to other tyres. I fitted mine with bare hands and not with any difficulty. As you have suspension you can afford to go to the upper end of the tyre pressure range - it should say on the side of the tyre. I expect 60-70 would be ok and you will find that the rolling resistance is pretty low with this sort of pressure and the new tyres. If you find this uncomfortable then you can reduce the pressures. Best of luck.

 

[flecc]

As Hal says, they are no more difficult to fit than any other tyre, just a little stiffer to pinch into the centre of the rim.

The pressure range is marked on the tyre wall, minimum and maximum, and I think it will be about 55lbs to 80 lbs for that size.

With suspension forks you can aim at the higher end for pressure to get the lowest rolling resistance. As you say, with bikes every part of the chain is important for the highest efficiency to maximise the power both you and the motor can get onto the road.

I'm looking for some new tyres for my Sprint 7. Would the Marathon Plus
26x1.75 tyres be a good choice?

 

[flecc]

Yes, they are exactly right for the Sprint, about the same size of the originals but easier rolling and better handling on corners. Buying recommendation as earlier in the thread for the best price.
