Tyre Pressures?

Post by Yorick »

Gonna try and get back into cycling. I enjoyed off road, but the constant wind puts me off.

So gonna start riding to and along the sea front.

What tyre pressures should I go for?

And harder or softer when I start going off road?

Ohh look an antique filing cabinetπŸ˜‚πŸ˜‚πŸ˜‚πŸ˜‚

If its gravel or Road work I'd try 28-30 psi FR & R and go from there (stealth edit, might want to go with Weeksy's settings if your a big lad). It'll be a little bit pingy off stuff but should be fairly snake bit resistant if you bounce up a kerb.

Answered your own point about going that low with tubes there - I wouldn't think about it as the risk of pinch flats will be very high.

Interesting. I dusted off my mountain bike I bought to help with my knee rehab to take the boy to town for a coffee and made me think I should ride a bit more for the exercise. For you lot it's a cheap rubbish MTB, a Voodoo Bantu I think. But to be honest I hate cycling and happy with heavy as it'll make me work more.

Anyhoo. I needed to put air in the tyres and the sidewall on the tyre said 40-65psi so I did an even 50. I presume that's ok? I'll be doing no jumps etc. Just bumbling about.

I was assuming you're riding on spiky harsh and 'fluid' volcanic rock.

The terrain over your island the rocks are grippy as far as individual items go but also because a lot of small stones, i'd want a it lower pressures than him who's going to the shop on a road.

Yes. But I enquired about riding on roads. Maybe misunderstandings.

Because his ask for it - and the manufacturers will know how stiff the sidewall is and he's putting it to a much lighter use.

Yours is because most of us have ridden Contis or similar 2.3 wide tyres both with and without tubes (with - many, many, many years ago) and know what works on both road and trail - and 35 is a very happy medium.

In that case, TBH it makes no difference really, 35, 45, 55, the only difference will be one is slightly harsher than the other, you'll save maybe 10s getting to the pub having them harder, but you'll feel every kerb more.

I think you mentioned sea front so that could have been challenging off-road.
When I commuted I tried different wheels and my favourite were balloon tyres (pretty much what you have) at 60psi, much more comfy than narrow tyres and very imprtantly for me less likely to puncture than lower pressures. When I tried lower pressures I found it a bit bouncy for the road.

There's an app for that. :)

In fact there's lots of them. I just installed this one and the recommendation for me and my bike is pretty much what I use and am happy with. ("Me and my bike" because the heavier you and your bike are, the more air you need in the tyres.)

App is a bit of a problem if you have different tyre sizes front and rear (as I do), or even a "mullet".

I don't think that's a problem, just run it twice, once for the front wheel, once for the back wheel. The recommended pressure isn't going to change because you put a bigger or smaller wheel or tyre on the other end of the bike.

And a "mullet"? What's that? (Well, I know it's a hair style that has, sadly, gone out of fashion, but what is it in the cycle context?)

Pressure is also dependent on usage (see above).

Mullet is where people run a 29" front with a 27.5" rear. Increased rolling and stability on the front, but quicker turning for the back... is the theory
