    Lowers pressures have more grip and compliance but will squirm more and are more likely to puncture from impacts. Higher pressures are more resistant to pinch flats but have a smaller contact patch and may feel harsh.

      I weigh a about 55kg and I run 22psi in the front and 25psi in the rear with 27.5 wheels and 2.3 inch in width, both with tubes. I know that this is a soft tire pressure but I am very lightweight, therefore I can afford to do this.

    Aggressive tyre pattern with higher pressure (for better roll) vs not so aggressive tyre (for better roll) with lower pressure.
    The struggle is real. Personally prefer quite high pressure for better roll, the difference in feel when accelarating is huge.
    Amazing looking trail though!

    @Marc28031984 5 лет назад

    I used to run high tire pressures (3 bar) but now I’m trying to get pretty low.
    Or, lets say, depends on where I’m riding.
    City, to get to work (high pressure, lower rolling resistance) or on the weekend, riding some trails and going down a hill with a good amount of little jumps (around 70cm)
    I once ran for climbing a pretty steep and long hill here in my local area, around 1.3 in the back and 0.9 in the front...and it felt good.
    I have to say, that I’m riding in the extreme zone, since I got 2.35 tires on my narrow 19mm rim.But it’s a light and very stiff one from Mavic.
    Crossmax XL.
    But around 10 years old...
    Now I’m building a completely new 27,5“+ bike with the almost other extreme.
    40mm rim, 2.8 and 3“ tires cause it’s going to be a enduro hardtail and I searched something more capable going downhill...cause my TrailCountry bike😅😂 isn’t feeling very stable going downhill fast.

    I really like riding with (very) low tire pressure, especially on the front (17.5psi). On the rear I ride a bit more, but still with low pressure, because I don't want to buy a new rim after every ride (22.5psi). But I also only weight about 60 kilograms, haven't got any trails with really big rocks where I live and ride tubeless.

    How much do you weigh when you ride? I’m 90kg or 14 stone in mine, run 28-30 in the back, 24-26 front. Locally it’s typical UK forest trails no rock and rides are up to forty miles. Do you think low pressure makes much difference to longer rides? Will give a lower pressure a try next weekend.

    • @rupedog
      @rupedog 5 лет назад +2

      That's about what I ride at 92kg...but so many other variables. If ur riding rooty, rocky stuff, try a bit lower. But if smooth trails and fireroad, stick with it. Tarmac/road sections will be slower with lower. But offroad (proper, not fire road/tow paths) will be faster, as tyre deforms round chatter plus more grip.

  • @andybrockbank3027

    I'm no racer and don't get the speeds by any means. I ran too much pressure on the front yesterday and spent the last 24 hours in a hospital bed with broken ribs. Back to a lower pressure when the ribs are healed. I'd rather wreck a tyre than wreck my body.

    Question here: There's a pressure limit on my 29x2.1 tires which says that the pressure should be between 40 PSI (Minimum) and 65 PSI (Maximum).. so what happens if I use them under their recommended pressures? 40 PSI is really rock solid which I dont really like.. I'm using Continental racekings for my other bike with 26-28 PSI which has no recommendation for min. pressure while it says 65 for max.. My new mtb's tires... Can't hold it.. PS: They are not tubeless.
    Edit: And also I really want to see what you can do with folding bikes with 20'! It would be fun to push them to the limits! and we can see that how long they can hold..

  • @meastabrooks1
    @meastabrooks1 5 лет назад +1

    Here’s the bottom line if you’re not an xc MTB racer: Run a 30-32mm inner wheel, with a medium to soft compound tire and at least 28psi in the rear and 24 up front. I’ve personally seen to many fails from chasing the “low” pressure for traction and breaking a sidewall or a wheel. Tire-roll also sucks when you’re running low tire pressure. Okay....so who am I to judge? 4 Colorado podiums in Enduro out of 4 races in my 40+ class. But, I ride with Pro’s and I’m always looking at how they do it, from suspension to tires and their pressures. Guess what....my buddy that weighs 158-162, he’s running 30psi minimum with cushcore in the rear and more fork pressure than I! He’s a top ten rider in the BME series. We’re all looking for that edge....so, minimize tire roll and buy a legit tire. Happy riding🌅

      FoVision well for starters, when I hit a big drop and the tire expands out it rubs on the inner part of my chain stays and it has rubbed the pain off. Other wise I love the big tires and also I want to try different tires and most of them aren’t in 2.6.

      @@tievox_gsr sounds like a clearance issue...might be worth reaching out to Norco considering that's what the bike was specced with. You may want to consider a DHF and DHRII combo in 2.6. WTB also makes some beefy tires and are known for being their true width. Maxxis tend to actually run a bit smaller But you can totally go 2.5 without issue on your bike if you'd like. Schwalbe has a few 2.6 as well.

    At 4:44 you mention that you're using a Trail King 2.3" in the back, however there is no such size for the Trail King, only 2.2", 2.4" and 2.6" are available for this tire (and 2.8" as well now it seems). Maybe you confused this with the Mountain King 3, which indeed is available in 2.3".

    • @frankthetankricard
      @frankthetankricard 5 лет назад

      It's a Trail King all right, you can see the print on the sidewall at 7:13, so he could be mistaken about the 2.3 size. Another possible scenario is that they have sizes/compounds that have yet to hit the market, they're sponsored by Continental after all.

    • @sp00n
      @sp00n 5 лет назад

      Yeah it's certainly a Trail King, I didn't mean that he confused his tire with a Mountain King, just the size. I also briefly thought about a new prototype tire, but I think it's pretty unlikely that Conti will offer another variant of the Trail King that sits between the already existing 2.2 and 2.4 size. All of their other tires are available in 0.2" increments (or more).

    • @willbennett7107

      Maybe but I always used to run them slightly harder than on my full sus because the rear tire has got to put up with more stress due to no suspension
      However if you run them lower the bike will feel more compliant but you will risk getting a flat easier

  • @frankthetankricard
    @frankthetankricard 5 лет назад

    I don't know how anyone can ride pressures as low as people generally claim. If I go as low as 30 psi I already feel uncomfortable because it's barely supporting my 175 lbs body weight. Around 32 the rubber can still deform just enough to have plenty of grip in the corners but going lower it feels unstable like I'm rolling through jelly. I'm on a hardtail so I'd be destroying my rims on roots and rocks. Then again, I've been watching the video closely to see how the tires deform under Neil to have a reference around 20 psi his tires looked like mine at 32. I don't know what makes such a huge difference. Air volume in theory could do that, the same principle as running tokens in a fork. But I have smaller 26" wheels to begin with and similar width 2.4 tires. Rim design alone couldn't possibly account for such a difference.

    Would love to have a table or formula of how rider and bike weight affects the ideal pressure... I know it just another variable, but it is a big thing that is obviously a factor... the same track, the same conditions, the same skill / speed level, but a 50kg rider compared to a 100 kg rider is going to be a lot of difference in impact forces on jumps and tyre distortion on sharp edges etc...

Perhaps tyre manufacturers have such research and someone knows about it and can provide a link... Your suggestion works for the same bit of trail... but what is a minimum setting, do rocks need more than smooth loam (and such...)

    • @flemming_j_
      @flemming_j_ 5 лет назад +1

      David King I highly doubt they have that research, lets take any brand out there, first they have to give a base Pressure based on EVERY single tire they have, under the same base, for example a 28mm rim, on dry rock, with an aggressive riding style, tubeless, no insert. But you might be conservative, Pressure changes, and your rim is 30mm, Pressure changes again. And by the Way, you ride Loam, not rock, again, Pressure changes. Only your own experience Can tell you the difference that fits you and a given condition. I usually tell people always tubeless, and start at 30 psi at go from there.
