[Closed] Bpw tyre pressure

Try twelvety psi

soft. Not a lot of pointy bits etc..

I always add a few psi to my rear tyre when riding at BPW, as some trails are quite rocky and pinch flats can happen quite easily.

*raises eyebrow at weeksy, wonders if sarcasm*

Too many variables dude. Which trails are you planning on running? Start with your normal pressures on the another flowier trails. But as you work up there are definitely some that will require an extra but if air if you're going down them with any vigour.
As with anywhere, what works for some definitely does not work for everyone.

Will mainly be reds but with names like rim dinger I was thinking of 25 psi as it is prob dusty there at the moment ?

*raises eyebrow at weeksy, wonders if sarcasm*

No, IMO BPW is quite tame in that context compared to other more old school centers as they're well worn. So while they're rocks, they're not sticky out pointy slate/flint etc, they're more 'worn' and IMO you can get away with a bit more.

25 seems about right to me.

*squeezes tyre*

Yep, about that pressure.

I wondered what Weeksy was on about, go too low pressure down some of the runs and you are asking for trouble. But I don't consider 25psi to be low pressure so we are looking at this from a very different perspective

This thread is great. No idea how heavy, fast/slow, aggressive, clumsy or whatever he is. Nor has he said what sort of bike and tyres are on the go, but yeah, 25

23

Depends what tyres you are running, if the sidewalls are pish, then more. If I'm on an uplift, I'll check the dh casing tyres on, then its 20f/25r depending on trail conditions, dry a bit highier, wet a bit lower.

I ran circa 25psi in my schwalbe magic mary and hans dampf supergravity tyres (so pretty stiff carcass) on Monday. Seemed good.

Really depends on speed, weight, tyres etc. The surface is pretty hardpack and a few trails (rim dinger, deep navigation) are just turbo-rocky.

Running full sus with Hans damf front and nobby nic rear

Way too many variables. Take a pump and see how you get on. I add a bit of air to my forks and shock FWIW

My point is that if you ran your tyres 'soft' (whatever that is) then unwittingly threw the bike into Deep Navigation or the like, you'd likely be coming out the other end with a remodeled wheel and tyre combo.
If you did the same on some of the faster blues you'd likely be pulling tyres off the rim.
You don't just put more pressure in to avoid cuts.

Most of the other advice above is good IMHO. Stick a few more psi in than normal(unless normal is bike parks and rocky gulleys), see how you get on after a few runs, and then adjust accordingly.

Edit: in fact, this is precisely what happens if you clumsily throw yourself into some of the rougher trails at BPW without adding a bit more pressure to your tyres.

As the rocks aren't actually sharp, DH casings are not so important as at, say Antur Stiniog. But there are a few spots where you might be landing on quite pointy rocks so a few more psi than you would use in your local woods would be a good idea.

I always add a few psi as where I live its just mud and roots, no rocks , so can get away with pretty low pressures. BPW whilst it doesn't have many pointy rocks, tends to be higher speed than my everyday riding, so more forces going into the rims.

Ironically, Rim Dinger has now been remodelled and is pretty smooth.

Ill generally bump the rear from 27 to 30PSI for a BPW visit. Tend to leave the front at around 20, but may change that after hearing some lovely front rim dings last visit! So yes, will add around 2-3 PSI to my tyres when visiting.

What about fork and shock pressure? And the big one: Peer pressure?! they all need adjustments 😆

G-outs in berms are the main issue there, wanging it down the smoother tracks. A few times I've felt like I was rolling the tyre off the rim. 😳

Therefore, 24.8 psi

Squeeze them a bit, pull a face, then give them another squeeze. Then go and have fun.

At antur everything is sharp, the place is made out of knives. At BPW the trails aren't sharp but there's plenty of bits like rim dinger that are fast and clobbery. Different sort of risk.

I broke my rear carbon rim there, through clumsiness rather than low psi while chasing a big bike but higher pressures would probably have saved it. I like my tyres pretty soft but maybe you don't. Who knows?

42. It's the answer to everything*

* I've never been to BPW

5psi more than usual. Has no drawbacks and might save you missing a couple of runs whilst you change a tubeless tyre

I depends completely on what trails you ride there, your tyres, if you run inserts, weight etc etc. If you are running the blues all day I wouldn’t worry too much albeit they can be fast so with a tyre like a Nobby on the back you can roll it and burp if running too low on the berms. If you want to attack some of the bigger trails they can be rocky and if you are clumsy on line choice it can be hard on wheels. Like NW I broke a carbon rim there (and seriously flatted and alloy one) but I am clumsy, heavier and hard on kit so my riding isn’t sympathetic. Lots of pinch flats too, my buddy ruined a fresh fitted tyre on first run once, same lad ruined another the next time we went. It’s not overly harsh, but I personally don’t get comments around it not being Hard on tyres etc. That’s almost as subjective as your post OP. Me personally I would want something a little sturdier than a Nobby Nic on the back, but that’s just me I guess

FFS!

If you're a typical STW member and pootling down the blues on your gravel bike/bikepacking bike/short travel FS then you'll get away with your normal pressures.

If you're actually riding the harder reds and blacks (bear in mind that the two red blend trails are harder than some of the blacks) then add a few PSI to tyres and shocks. I don't generally go much higher than usual, as, apart from a few trails like Deep Navigation and Zuts Alors, it's not full of rock gardens.

How could you possibly imagine that someone asking what tyre pressure to run is a “typical STW member”?? 😂

If you need to ask what tyre pressure, I suspect two things;
1 Troll
2 you shouldn't be going there

It would be a pretty poor attempt at trolling, and I don't see why asking about tyre pressures would mean that the trails would be too taxing for you, if that's what you're implying.
