Weird puncture location

I have used this and haven't had any issues.

I would say you could run 0.1bar less if you really wanted to.

Its a good start point.

I'm 75 kg. I do ride a lot on rocky stuff, so I guess increasing tyre pressure is the solution. I am also riding a hard tail where as previously I was on a dual suss, so the shock probably helped absorb some of the force of the hits. 

 

Good point and probably the reason. I switched to a long-travel HT from a FS trailbike about 3 months ago. Haven't suffered any pinch flats, but did end up with 3 serious dings in my rim. Previous rims on my FS lasted 10yrs (although they were dinged to hell by that time)

 

I've also just fitted the cSixx Foamo Double Decker rim strip to my rear wheel. Considering your situation, I think it might be a good investment. I can honestly say I did not even feel the weight difference. Time will tell how effective it is.

 

Edit: I also run 650b x 2.25 Ardents

Can anyone tell me the difference between the maxxis minion exo and dd? Basically I'm looking for the strongest/most durable tyre. Not really concerned about the weight.

 

The Exo casing is their "normal" casing. The DD version is their "Double Down" casing which is exactly what it sounds like, a dual casing. The DD version is extremely tough, intended for very aggressive riding, and will hold up to lots of abuse, but there is obviously a big weight penalty.

Test your tire pressure guage..... what you THINK is 2 bar may well be significantly less.... or more - as the case may be.

 

My park tool pump guage is out by 0.5 bar at low pressures - seeing as I run pressures as low as 1.4 - this could be a problem if I believed that guage.... fortunately I have another more accurate one.

Can't comment on the above tyres, but will share my specs with you for my usual riding (Tokai / Jonkershoek)

 

Rider weight: 100.0kgs

Bike weight: around 14kgs (Niner RIP 9)

 

Trail Day

Front tyre: Maxxis Ardent LUST 29x2.25" @ 2.0bar

Rear tyre: Maxxis Crossmark LUST 20x2.1" @ 2.3bar

 

Sometimes I let a few pssts of air out of the tyres on hot afternoons, and when I get home the pressures are Front @ 1.7bar and Rear @ 2.0bar, but generally the above works for me as my go-to all round pressure. I'm a cautious rider, but ride abusively when feeling confident and know the trails abit better.

 

For your weight and tyre size & volume I'd stick around similar pressures to what I'm running depending on terrain/ride style etc.

Thanks Yusran

Very cool, thanks

I have also been thinking that. Its an old super cheap floor pump. How accurate do you think the gauges are at petrol stations?

Don't think the gauges at the petrol stations are accurate. I've pumped my car tires to 2 bar at a station. When I tested with my digital gauge later it read 2.5 bar.

 

Also had garage pumps over reading as well

 

Probably best is a digital tire pressure gauge. Can buy one for the thinner valves. Or get one for much cheaper from Midas and buy a valve adapter.

Most people are mentioning snake bites here. Isn't one of the advantages for going tubeless is that there are no snake bite punctures?

Petrol stations I have compared agains have been from pretty close to about .3 out.... better to get a decent guage.

Nope - if you try hard enough you can snakebite the tire....

[porqui]

Tyre pressure issues seem unlikely. I am 110kg, with Onza Canis and Ibex Combo on a Spez Stumpjumper at 1.6 bar at the front and 1.8 bar at the back. 30mm internal width rims. I ride very rocky terrain (Hakahana), I'm not careful in rock gardens and I no issues whatsoever with punctures.

 

Maybe that specific tyre has just degraded at the sidewall or has some sort of manufacturing issue - it does happen from time to time.

 

I would check my pressure gauge for accuracy if I were you.

yes, also confused.

 

is this a tubeless setup?

[solty]

I've used a regular bicycle-tube patch to fix one of these tubeless snakebites before. Hole was right nexto the bead. Patch goes on the inside of the tyre, obviously. Take care to clean all the old sealant from the area.

[ct biker]

yes, also confused.

 

is this a tubeless setup?

yup, tubeless set up. Snakebite punctures seem to make the most sense to me. 

[s14phoenix]

yup, tubeless set up. Snakebite punctures seem to make the most sense to me. 

 

if there is no other foreign object the rim bead has actually punched a hole in the tyre next to the bead. This is some times also through the tyre as well where the said rock has punched through the tread and then through the tyre a second time next to the bead.

 

all possible and in definition still a "snakebite" puncture. I went through a brand new Racing Ralph snakeskin like that - I fitted back the same size old nobby nick SS and have not had a similar problem (The nobby nic casing has more volume and is slightly thicker)
