    Big tyre on rigid?

    Been looking at some posts about running a big tyre on a rigid set up at low psi and i am considering getting one, i had some maxxis high rollers DH tyres once and can remember how heavy they were

    I was wondering if you guys notice the big tyre slowing you down at all due to the extra weight and width.

    Try to find some wide tires with a supple casing. Don't just use DH tires. Wider tires roll faster but only if they can deflect and absorb the bumps.

    In a word, no.

    There are some conditions that just don't merit a really big tire, but usually those are the same ones where the big tire won't hurt you either.
    26"
    The WTB Mutanoraptor 2.4 is a nice front tire for riding rigid. Big casing, rolls fast, hooks up fairly well in most conditions, and isn't too heavy @ <600g. It's my favorite all time 26" tire.

    29"
    I've raced with both a Kenda Nevegal 2.2, and a Maxxis Ardent 2.4. I liked the Nevegal better although it's about 150g heavier; I never could dial in the Ardent's pressure well enough.
    I have been running an Ardent 2.25 up front lately. With it I have been able to find that sweet spot between huge rubber mallet and rim strikes. It's lighter and rolls faster than the Nevegal.
    In drier conditions I've been quite happy with a Conti Race King 2.2. It is my Summer race tire (barring hurricanes, tornadoes, tropical storms and the like). It's casing gives it more of a "vertical" volume, making it great for rigid. It rolls super fast, but still hooks up okay in all but the worst slop.

    Started with a 2.1 Maxxis Aspen. Not too bad and only 535 (weighed) grams for a 29er tire. Had to run about 20 psi or I banged my rim ALL the time. Have since switched to a Schwalbe Racing Ralph 2.4 and am loving it 17.5 - 18 psi and takes alot of the hits for me. At 635 grams it is much better for my rigid riding. The photo is of the Aspen. I ride in north central Florida, so we have alot of roots. 1"- 3" high, all over the trails.

    Thanks so far.

    I live in the UK and where i live and ride there are lots of roots from small to large, it also gets very damp and muddy in places in the winter which is nearly upon is so would the WTB Mutanoraptor be able to cope in slippy conditions?

    My current tire is a 2.1 maxxis ignitor but i cannot run much lower than 30psi without risking pinch flats

    Tubeless is your friend when running rigid and looking for low tire pressures

    UK woods / mud / roots rigid rider here..

    26", I like Rubber Queen 2.2, maybe a Race King out back when it's drier. On the 29" it's Race King or Ardent UST 2.2 at the back and an Ardent EXO (works fine tubeless) 2.4" up front - until the Rubber Queen black chili UST 2.2" is available.

    I'm tubeless on P35's on the 29er - wide rims made a massive difference, I don't notice the extra weight much but I do notice the tyre's supported a lot better at lower pressure. Comfier and grippier - win-win..

    Use bigger inner tire if you want to run in low psi.

    Bigger tire is not always slowing you down, it all depends on the thread.

    Last time I use ardent 2.40 and it's amazingly has low rolling resistance, also this tire is tall means the diameter is big. Honestly this tire feels like 700x23c and I use it on road but for off-road I don't have confidence since the wall to tall tends to slip a lot on rocks.

    I go from 24x15 to 22x13 because of this tire very light for me. I haven't try the 2.25 but since I aim for the diameter to get more GPI so I'll stay with 2.40.

    I just switched over to a 2.4 Racing Ralph from a 2.2 Conti race King, the Ra Ra is much more comfortable!!! Better handling too

    You should check out the fat tire forums here. Those guys run crazy huge tires with ~ 10 psi.

    Especially of interest to you will be the FAQ thread. There is some in depth discussion about tire pressure/size/rolling resistance/speed with actual lab analysis.

    I first started using it as a Winter tire. It's pretty good in just about everything.

    now thats something you dont see every day.

    noy much difference in price between the WTB Mutanoraptor and the 2.4 racing ralph will probably try one of these.

    I have only built the bike this summer and the wheels are not tubeless compatible unless i use one of them kits.

    I use a three inch Gazzaloddi with the surly instigator fork and run my tyre at about 10 psi.Good fun and very good in the snow.

    That bike is all kinds of WIN cept for the brakes. I think you need bigger brake pads.

    I recently put on big fat 2.3 WTB on my rigid FC and it's made the bike more comfortable on rough trails.

    Is there anywhere to get Racing Ralphs for a reasonable price?
    I'm not trying to spend $90 for one tire...

    I started rigid on my 26er IF singlespeed with a 1x1 fork. Began using a Serfas DH style tire, then I moved to the IRC TrailBear tires, then to the GEAX blade which is huge and light and rolls and grips well but I don't think it is made anymore. There is a possibility that the Trailbear is available in a 2.5, might be called the Freedomcross now.

    Then I moved to a 29er rigid and started with a Rampage up front, then i moved to a WTB Stout, (thicker casing and stiffer sidewalls) then to a WTB Dissent (DH Casing and weight, less air volume but huge amounts of rubber on the ground) and finally this:

    <a href="https://www.flickr.com/photos/davidandmelinda/6140686532/" title="IMG_4977sm by Melinda and David, on Flickr"><img src="https://farm7.static.flickr.com/6169/6140686532_d0db85e498_b.jpg" width="1024" height="683" alt="IMG_4977sm"></a>

    I like to experiment with tires. The best performing rigid for me in the 26er was the GEAX tire bar none. Huge supple thin casing and ample knobs. Run tubeless I could go around 22-24psi, the traction was fantastic and the set up was nice and light. For the 29er the best feeling combo is the rampage but the traction was a little limited on the skittery stuff I ride in the desert southwest. The fat front is amazing in the other realm supple, compliant and tractiony but not light be any stretch of the imagination...but the traction action is insane, especially on skittery loose over rock.

    The common thread here though is the wider rim. For my 26er I used Rhynolites and for the 29er I started on skinny salsa rims, them moved to wider WTB Laserdisc Trails, then graduated to Sun MTX29er rims, now I have the Large Marge up front.

    The wider rim flattens out the casing making it more able to handle the lower pressures without folding in corners and give you more air volume in your tire so you can drop down overall air pressure. A fat tire on a skinny rim is a recipe for poor handling and bouncy feeling ride.

    Very happy with the 2.4 ardent on the front and 2.4 purgatory on the rear. 20psi. Going to experiment with lower psi on the front. That with carbon carnegies and I don't miss my old marzocchi a bit.

    2,4" Racing Ralphs front and rear. Works well but you have to hurry because 2012 there seems to be no 2,4" RR.

    Tubeless and wide rims help quite a bit, as stated earlier.

    I've been running 2.35 Bontrager FR-3's with great success on my 29er. I generally run them around 20 psi.

    Heh, Rockcrusher I think we're drinking the same kool-aid! I got pretty much the same setup on my Performance XCL. Stout in the back and a Larry in the front. Climbing rock gardens in the rain is a blast!

    Before this setup I was running a Weirwolf 2.55 in the front with a Stout in the back.

    I remember this beast from the Tour de Fat this year.

    I run a Ardent 2.4 front/ WWLT 2.55(2.3) rear tubeless on flows. Can run as low as 20psi and does take care of some of the bumps but it's no 80mm+ of suspension.

    I am currently awaiting the release of the new WWLT which I will then go front rear on, the Ardent is a nice tire but I have other plans for that tire (WINTER PROJECT).

    I don't have an image right now, but I'm big on the Kenda Karma 2.25. Rolls nice and bites in most terrain. Pretty light too.

    Rockcrusher, did you run ghetto tubeless on the Rhyno Lites?

    Looking at tubeless options for v-brake SS (ie, mavic xm819) and wishing they were wider... and hmmm have some RL's already that I could comission for the job, but heard they are a PITA for tubeless...

    I got the stans rubber strips and they were perfect. They mounted up easy with a floor pump and never burped. The easiest conversion I have ever done.

    Be careful with those Racing Ralphs.. I thought I was taking it easy on them (no rock gardens) but i just noticed a split forming on the sidewall.. the threads busted rather easily. I run with tubes and keep about 25psi in them.

    Well i ended up with a maxxis ardent 2.25 fitted it and went for a ride today and you can feel the extra cushioning even though i am currently running a reba up front.

    The best thing was the grip, in the UK the woods are now all slimey in places and the ardent didnt put a foot wrong it went where i pointed it and i could feel the high roller on the back sliding about trying to follow.

    Good choice. I finally was able to get the pressure dialed in on the Ardent 2.4".
