Punture Proof a 29er Commuter Mountain Bike

Hey Guys,
I have the Aldi Mountain bike that i use for commuting about 10k's, still with stock tube's and tires. Had a few punctures that I've patched up but whats the best way to be as puncture proof as possible?
Any advice appreciated.


  • Go Tubeless

  • Tyres make a huge difference. For onroad I used to use Schwalbe Marathons IIRC but I haven't ridden for a few years now. They had very good puncture resistance and grip. A mate put me on to them as he does thousands of km per year commuting.

    • Good to know. I got a puncture on my Aldi 29er last week. My other bike, a roadie have Continental puncture protection tyres.

  • Shwalbe Marathon Plus tyres, been using them for years on different bikes and never had a puncture with them

  • A self-sealing inner tube can be a cheap way to help.

  • Puncture Proof is a myth, you an still get a gash which defeats all the below :

    1) Kevlar lined tyre.
    2) Get a Tyre Liner
    3) Puncture resistant tube - they are thicker than regular.
    4) inject tube with the goo which will self heal 'some' punctures.

  • Tubeless.

    Although slipping a tyre liner in is cheap and easy. I’ve run tyre liners in my commuter bike for ages and have only had a couple of pinch flats since despite getting regular punctures before hand.

  • Thanks for the reply's guys. I like the idea of tubeless, but i might put that on hold until i get a bike or rims that are tubeless ready.
    Schwalbe Marathon Plus seems like the go, maybe with a tyre liner also.
    Whats the deal with tyre sizes? My current are 29 x 2.25 (57-622), bikebug has Schwalbe Marathon Plus in 700 x 35 and 700 x 40. Would these be too thin for my bike?

    • They'd probably be OK. Being a MTB your current tyres are probably much wider than the rim. 2.25 should be around 56mm so coming down to even a 35 means it'll be narrower by around 10mm each side of the rim. If you think that may be too narrow go with the 40 instead. Remember you'll be running higher pressure than an offroad MTB tyre combined with the smoother tread and narrower tyre you'll find the bike rolls and pedals easier and faster as a bonus.

  • Also, can i get confirmation that a size 700 tyre can be referred to as 700c, and can also be referred to as 29 inch, AND has an inner diameter of 622 (only compatible with a 622 rim)

    • Yeah same thing diameter wise. 29 is relatively new to MTB. I'm guessing the reason they didn't just call it 700c is that MTBs have always used inches.

  • Just an update/round up. 28" also = 29" apparently. I found it unnecessarily confusing to learn about tyre sizes.
    Ended up going with Schwalbe Marathon Plus 28 x 1.75, going well so far. Thinner tyre gives noticeably less rolling resistance with a sacrifice of grip/stability.
