29" Tire Recommendation

[oldtown169]

I was thinking about going wider tire 2.25" or larger. Any benefits to a wider or narrower tire?

Probably being used 75% of time on asphalt and the other 25% offroad - crushed stone. (Old railway bed stuff)

Most important to me is to have the best flat protection against glass.

Larger is better in the ebike world (generally). You should get a mixed use tire for your needs. For flat protection against glass, Schwalbe Marathons or use a tire liner like I do. I prefer Tuffy's.

Anybody running these Schwalbe Marathon Plus RLX 700 x 45 C .....

Those get very high reviews in other sizes here and elsewhere. I might try them myself in the future for better flat prevention. 8)

My bike came with 2.25" tires. I'm not sure about the rim size. My back wheel is now a 700c DH19 from CellMan which I still have my 2.25" tire on it. Those Marathons are a 45 which I think are 1.75" wide tire. Correct me if I'm wrong. I'm going to lose a 1/2" tire contact. Should I look for something wider than that ?

Wider does mean more chance of picking up glass, while the narrower will give you more maneueverability and lower rolling resistance. 1.75 is not too skinny for street running. It might help with efficiency a bit too. I just said that wider is better assuming you were riding some crazy fast bike.

How fast are you going?

Yeah that's what I was sorta thinking about going wider and picking up more crap. Average speed around 25 mp/h...

Yeah... don't go with a wider tire. That will just pick up more glass and also make pedaling a chore at that power level.

Those Marathons are really nice (based on numerous reviews from everyone I've talked to) , you'll be happy. Only gripes are usually the price.

Thanks for info guys. I think that tire is now on my short list!

I stopped at the cycle shop a few days ago. They had a 29er Fat bike. running Surly Knard 29 x 3" tires.

Wide tires may touch more crap in the road, but they do so at a lower ground pressure, meaning stuff doesn't penetrate as easily.

I like wide tires because of the soft, sandy shoulder along my commute. I would hate to eat gravel for breakfast from a skinny tire hitting that stuff if I get forced off the pavement or stray from the trail. Of course, flats are bad at any time; but the skinny tires don't prevent them. Rather, they can blow easier and more frequently at the higher pressures they maintain from sudden impact, while carrying the increased weight of the motor and battery. They also get squirrely in cracks and along uneven lateral ridges that I encounter along the side of the road. They pop like a firecracker when they blow, but that excitement fades quickly when you're doing the walk of shame. :lol:

Thanks for all the responses. I ended up getting VEE RUBBER V8 . I also used MR.TUFFY liners!

Is there a source on the statement about wider tires being more prone to flats? Wider tires have lower rolling resistence, but higher drag (aerodynamics).

Clearly, OP decided to go on the extreme side of tire width. What rims are you mounting those tires on?

The selection for tires seems seems hard to narrow down, it's kind of frustrating. I've heard mixed opinions on tuffy liners and liners in general, some people say they cause flats, some say they are essential, some say to use old inner tubes instead.

I'll give my 2cents on what I know, on the rest others can advice you better

Rolling resistance is given by the "softness" of the compound, irregularities and deformation and other less significant things. By this rationale:
*large tires are usually softer and grippier - so more rolling resistance
*they have bumps to grip offroad - so more rolling resistance
*their max PSI is lower than slim tires, they deform more - so more rolling resistance

From my experience wide tires also have more flats, just because slim tires are made of harder compound usually. Not always, wide-ish tires like the Schwalbe Marathon are tough as a 700-23C race tire. That said, offroad fat tires grip better and dampen better than an 80PSI 700-23C, they just go places slim tires can't get to. As far as flats are concerned you should get tough compounds be that slim or wide, but as far as rolling resistance goes nothing can beat a hyper inflated 0.6"-wide race tire.

before you put your new tyre on

get the old tyre, and cut off the inner ring (the bit you stretch over the wheel rim)

do that on both sides

then put that inside your new tyre

I had loads of flats.. a couple every week... fitter my old tyre inside the new one 6 months ago and I've only had 1 flat since then


p.s. when I first fit them, I blow them up, let them down again and blow them up the final time... helps to center everything...
(I do this anyway, not just with my twin tyres)
