60TPI vs 120TPI tires? pros cons?

Cyclocross and Gravelbiking (Recreational) This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like :The Dirty Kanza".

60TPI vs 120TPI tires? pros cons?

I really could use some opinions from you guys and gals. Fixin to buy me some gravel tires. 60s supposedly last longer the 120s better ride. I would love to hear from other gravel grinders

What you said is right with regards to durability. On top of this, 60s will be a bit heavier than 120s. Also, rigidity is different, where the 60s will also have a stiffer casing, which may make installing the tires on the rims a bit harder.

All the 120tpi tires I've used(or 330tpi due to marketing) have lasted a long time. They have been durable and reliable.
In terms of durability, its not like 60tpi is a basketball and 120tpi is a balloon ready to pop.

120tpi are lighter, ride better, and are faster while still being plenty durable(in general)
The one downside is they cost more.

Don't compare across brands though they can use different casing materials. Some 60tpi casings(tubeless ready) ride better than 120tpi casings if set up tubeless compared to with butyl tubes

Mine are listed as 60tpi, but with a "light and supple" casing. Set up tubeless.

Generalizing: 120 is lighter and more supple and more expensive. 60 has a thicker cord is harder to cut than the thinner 120 cord. The 60tpi is sometimes used on tires with extra puncture protection.

Isn't the TPI spec relatively meaningless? I've heard some manufacturers will make a tire with two 60 tpi layers and call it a 120 tpi tire.

Usually it is meaningful. Continental loves to say they have 330TPI, when it is really 3x110tpi. Basically you have to divide any TPI number conti has by 3. They label their 60TPI tires as 180TPI. Everyone else seems to do it legitimately .

TPI is meaningless in 2019. This article and the comments are a good primer why: https://janheine.wordpress.com/2015/...e-performance/

The issue gets compounded even worse now that there are tires designed to bridge tubed/tubeless use as well as different manufacturers making difference tire construction choices with respect to using tubeless fluid.

For example, the Panaracer GK slicks in 650bx48 are a terrible tire. Stiff, uncomfortable and slow despite having thin tread and 120 TPI . The TPI number is from two layers of 60 TPI , counted twice.

WTB Horizon is a great tire. Supple, comfortable and rolls fast even though it has extremely thick center tread - TPI is 60. The TPI number is from two layers of 60 TPI , counted once.

Applying TPI like it used to be back in the 70s and 80s and the Horizon is going to be a much worse tire, on paper. The reality is completely opposite, Horizon is a great tire and that specific size of the GK slick is not. TPI also has almost nothing to do with cut or puncture resistance, both are much more concerned with tire durometer and pressure than TPI. I think I probably purchased tires based on TPI in the past but I can't remember the last time I did so, it's not a good way to choose a tire. Taking weight and TPI together is better than nothing but honestly there's no good way to pick a tire without being able to hold it in your hand - even then things can be different when you ride it.

Other examples:

Pancenti Pari-Moto has the same TPI as Compass Babyshoe Pass - 120 TPI, but it is significantly more supple and significantly less durable because the sidewall is ~1/2 the thickness of the Compass and the tread is ~1/3 the thickness.

MTB tire; the Kenda Slant Six tube-only SCT model has the same TPI as the tubless SCT model - however the tubeless model has a sidewall that's almost twice as thick and is a significantly stiffer, slower and less comfortable tire with less traction.

Like others have said, tpi theoretically can make a difference when all else is equal... but all else is often not equal.

I think TPI used to be a better indicator of suppleness and quality than it is now. I donít know why that is.

interesting comments, but there are many tires that are offered in both 60 and 120 configurations. In that case, all other things are equal, and it is a valid comparison. The 60TPI tires are often sold and a more heavy duty or flat resistant tire though (with a different construction).

Idunno - 120 makes me think the tires are more supple, so it must be so! ;-)
