The technology we use to create our tires is the secret of our success. While it's our secret recipe, we are happy to explain a few details that come into play when making an ere tire. 

At ere we use 3 types of casings:

  • nylon 60TPI 
  • nylon 20TPI
  • cotton 320TPI  

TPI stands for Treads per square inch.  This determines how tight the weave of the fibres in the casing is. The TPI count of the tire influences the riding behaviour of the tires. The more the TPI count the more supple the tire will be and the more responsive it will behave on the road.  

ere casing layer technology 

Armis 1 is our lightest layer of protection designed to be flexible and light. It offers a strong protective guard against outside penetrations under the tread pattern and enhances the flexibility performance of the overall tire. 

Armis 2 is very similar to Armis 1. The difference is that it has an added “bead to bead” layer in order to it air seal the tire for tubeless use. This is referred to as TLR in our documentation.  

Armis 3 is used for tires that need heavy-duty protection against the elements. It can face heavier impact loads on the sidewall and can withstand rougher user experience conditions such as off-road usage.


ere tire bead 

Some tires are equipped with an Aramid Bead Cord (ABC). This is an ultra-strong and lightweight Kevlar cord that holds the tire in position on the rim following international ETRTO size regulations.  

Some tires are equipped with a Nylon Bead Cord (NBC). This is a strong nylon cord that holds the tire in position on the rim following international ETRTO size regulations.  


ere rubber compound 

We use Ultra Performance Compound (UPC) that is carefully engineered from natural rubber that has been harvested from rubber trees close to our tire factory.

We add just the right degree of additives without compromising the latex rubber to reach the right durometer of 65A


HPC stands for High-Performance Compound. This has been carefully engineered from synthetic rubber, we add just the right degree of durability without compromising performance, comfort and control. It has a slightly more elongated lifetime due to its engineered composition.  

We use a durometer of 65A for a perfect mix of performance, comfort and control.  

This measure maximizes the feedback from the road during a ride and builds confidence in the tread and overall tire. 


ere tubular tires 

In the past, tubular tires were the only method for making performance tires.  

Therefore they are seen as the holy grail in terms of reaching the ultimate tire-wheel performance combination. This is also the reason why many professional riders still swear by this setup. Technology has advanced since then and now we have tubeless and clincher tires that come very close to tubular performance.  

Tubular tires still have advantages in terms of tire pressure and handling, and that offers some riders an extra bit of confidence and confidence is everything when it matters. 


Every road rider knows that when it comes to performance road tires it's all about high grip, low rolling resistance, and high anti-puncture protection.  

And of course, weight and price also play a role. Puncture protection is extra layers added to the tire that shield it against punctures.  

If you remove these layers the tire will be light and will potentially have a low rolling resistance, but the tire will also be easy to puncture. Anyone who knows what it takes to change a tubular tire is not going to be happy with an easy puncture. So the trick is to try and keep up the safeguard of the tire while keeping down the rolling resistance. In addition to this, you also want to create as much grip as possible. We’ll happily accept that extra 65 gram of protection knowing that high-performance tires are expensive and changing a tubular is no joke. However, the performance of a tubular tire is still unmatched, so this is the reason why pros are still riding with tubular tires. 

The ere Genus tubular tire offers the best mix possible - There is no road racing tire with a more aggressive leaning edge grip pattern. Moreover, the rolling resistance is as low as one could expect from a tubular tire, and the puncture protection is as high as an  

all-season tire. 


The best performing road tire in the world 


Even compared to the Vittoria Corsa Speed (previous best overall performance worldwide), the Genus CT excels in the overall score. The ere Genus CT is the best performance road tire in the world today





Sometimes there is an easy way to explain our technology, here's how our 120TPI vulcanised tires work and how the myth of tire flexibility should be explained.
This does not mean 120TPI tires are not different then 320TPI, because they are, but in terms of casing flexibility a 120TPI tire has come a long way since production techniques have evolved. Take look at this video that explains just that.





Ere will adhere to the new 2021 ETRTO sizing rules, and all our new tires and wheel/rim models will follow the below sizing chart to conform with the international ETRTO standards, so check your wheels and tires when you are up to replacing them, it's good the know and understand that the combination of the product your are about to buy is compatible in terms of sizing, the below chart will help you find the correct combination.
