Will moving from 2.1 to 2.35 tyre reduce pinch flats?

edited June 2009 in MTB buying advice
Have had a lot with my 2.1 Nevegals but think this is prob down to low pressures. Am going to buy more Nevegals (unless these are esp prone to pinch flats?) as they perform fairly well and the choice of other tyres is bewildering. Would the greater volume of air in 2.35s reduce pinch flats? Then again, same psi means same vol of air. The 2.1 Nevegals are quite wide, are the 2.35s the same? I ride hardtail trail/mountain/freeride if that makes a difference.

Cheers

    i've never had pinch flats on nevegals, that i would often get on other tyres, even on relatively low pressures, so try increasing the pressure in your tyres.

    the bit about moving from 2.1 to 2.35 i am not sure it would help unless you then run the wider tyre on higher pressure.

    I run Nevegal 2.1's never had a pinch flat.

    The 2.35's are pretty big (as are the 2.1's) and noticeably draggier than the 2.1's

    try upping your tyre pressure a little

    I've had a few on my 2.1 dtc nevegals, but most of my trails are rocky. I'm contemplating going tubeless.

    Can't comment on Nevegals but 2.1 Nobby Nics pinch flat just for fun whereas the 2.25s are loads better. Light, fast tyres are OK but there's a price to pay.

    Put bigger inner tubes. For 2.35 tires, inside the 2.1.

    Cheers guys. I've been using 2-2.3 tubes, might try some slightly bigger ones.

    Greater volume will help reduce pinch flats, but stronger side walls will reduce them even more.

    Same psi does not mean same volume, if you run a larger tyre with teh same psi in it the air volume will increase within teh tyre as there is a larger volume of tyre to fill in the first place.

    When you say you ride HT trail/AM/Freeride, do you ride round trail centres, off the side of proper mountains or huck your way down them? if you're airing towards hucking why on earth are you riding 2.1" tyres?

    With the same psi, stronger sidewalls will stop the tread part of the tyre compressing to the rim on big hits? Which tyres have strong sidewalls?

    I ride all the above but not hucking huge. As mentioned the Nevegals are pretty wide for 2.1. I'm happy with the grip from the 2.1s, but is there another advantage from wider tyres? Stability on landing, puncture resistance...?

    I've found that Nevegals and Blue Grooves pinch-flat with alarming regularity, especially if I'm hanging it out in the rocky stuff.

    They have very thin sidewalls to keep the weight down, but this can mean that unless you inflate them to a reasonably high pressure, they flex too much. But of course, if the pressure in them is high, you lose grip.

    I find that 40psi is enough to prevent pinch flats, but I lose grip in the loose stuff at that.

    I've gone back to High Rollers.

    Go tubeless and never worry about pinch flats again

    What pressures do you run? You need a pressure guage not tyres

    Cheers for advice guys. I ordered the Nevegals but CRC have missed the post, so am going to try to change order to something from Maxxis.

    The guage will make up for the fact that the tryes have worn out?

    No of course not. I thought the issue was with pinch flats, there is no mention of the tyres being worn.

    You'll pinch flat a 2.35 just the same as a 2.1 if you dont use the correct pressures for your riding style and weight.

    I'm not trying to be flipant I'm just pointing out that it is important to find a pressure that works for you irrespective of the size of tyre.

    pretty much most people i know on trail centers are riding with 2.35" tyres mostly for grip reasons.

    i found the wider tyres generally pinch less but thats usually they have heavier side walls, its a trade of with the type of riding you do.

    Everything i do is rocky and rooty and the wider tyres (2.35 kenda blue grooves) give excellent grip where something like the 2.1 squirms like it doesn't want to touch the ground.
