What tire is best for me?

As a general rule of thumb, we recommend using the widest tire you can fit with safe clearances. Not sure how wide you can go? Check out our blog post on measuring clearances on your bike.

For paved roads and gravel, our ‘all-road’ tread tires are the best choice. For muddy conditions, cyclocross and snow, check out our dual-purpose knobby tires. They are also a great choice for riders who prefer a more aggressive tread on loose surfaces.

Which casing is best for me?

Rene Herse tires are available with four different casings for different riding styles and conditions:

• Standard: The supple casing that has made our tires famous: comfortable and fast, yet it’s also strong to withstand considerable abuse. Available on all models (except 26″ x 1.25″ Elk Pass).
• Extralight: Ultimate in speed. Ultimate in comfort. Ultimate in light weight. An extremely fine and supple casing that you’ll otherwise find only on hand-made tubulars. Available on all models.
• Endurance: The same extra-fine threads of our Extralight casing, but pushed closer together for a denser weave, and with an additional protection layer on the sidewalls and under the tread. Excellent resistance against punctures and abrasion, while keeping most of the speed and comfort that has made our tires famous. Click here for the tires that are available with the Endurance casing.
• Endurance Plus: Thicker threads for even more strength and resistance against cuts and abrasions, plus an even stronger protection layer on the sidewalls and under the tread. A tire for durability above all that still will surprise you with its speed. Click here for the tires that are available with the Endurance Plus casing.

Rim width?

With supple Rene Herse tires, it doesn’t matter how wide the rim is, as long as it’s no wider than the tire (outside width). If the rim is too wide, the tire can blow off, because it doesn’t properly engage with the hook on the rim’s sidewall. Rene Herse tires up to 44 mm wide can be run on rims as narrow as 20 mm. For wider Rene Herse tires, we recommend a minimum rim width of 23 mm.

You may have heard that matched rim and tire widths make the tire sidewalls more vertical, so they bear more of the bike and rider’s weight. This works with stiff sidewalls and allows running a lower tire pressure, but also decreases shock absorption and comfort.

With supple tires, almost the entire weight is supported by the air pressure of the tires. Whether the sidewalls are vertical or bulge makes very little difference. The most extreme case is a tubular tire, which touches the rim only in a very narrow spot, yet offers great handling and comfort.

Minimum Pressure?

The minimum pressure of your tire depends on your weight, so we don’t list a minimum pressure for Rene Herse tires. More information about minimum pressure is available here.

Tubeless or tubes?

Many Rene Herse tires are tubeless-compatible. This means they can be set up tubeless (with a sealant) or used with tubes.

Tubeless setup reduces the risk of pinch flats, which can be useful when riding at high speeds across rough terrain. Fortunately, the wider tires found on most bikes today have made pinch flats less of a problem than in the past. Disadvantages of tubeless mounting are higher rolling resistance due to the liquid sealant inside the tire, more difficult setup, and closer rim tolerances required to prevent blow-offs.

If you are concerned about punctures, you can use sealant inside your inner tube. (The tubes we sell have removable valve cores.)

Hookless rims?

The hook on most rims helps hold the bead in place, making it more difficult for the tire to blow off the rim. Without a hook, the tire/rim fit must be very good to ensure that the tire cannot blow off. High-quality carbon rims are hookless, but also control the diameter of the bead seat very closely.

We have worked with Enve and Zipp to test the fit and safety of our tires on these companies’ carbon rims.These rims are fine to use with all Rene Herse tires, even tubeless. Other high-quality rims should work as well. Make sure the tire has a slightly tight fit on the rim.

Hard to mount

Push the tire bead into the ‘well’ in the center of the rim all around the tire, and make sure it’s not caught on the ‘shelf’ near the edge of the tire. The tire bead does not stretch much, so it needs to be in ’well’ to give you enough slack to lift it over the rim sidewall. Also check out our tire instructions above.

Tubeless tire blew off

When a tire blows off the rim, it’s usually because the rim is slightly undersize. Even if the rim worked with your previous tires, supple tires require tighter rim tolerances than tires with stiff sidewalls. In most cases, the problem can be solved by building up the rim bed with extra rim tape. Some mechanics use thicker Gorilla Tape to build up the rim bed. The tire should have a slightly tight fit on the rim.

If huge bursts of air from a compressor are required to seat the tire, air is escaping between tire and rim bed – a clear sign that the rim is undersize. Don’t mount the tire like this: Build up the rim bed with extra tape to reduce the risk of the tire blowing off the rim.

Leaking through sidewalls (tubeless)

We have found that Panaracer Smart Seal greatly reduces the risk of tires leaking through their sidewalls. Other sealants often don’t have enough solids to seal the thin and supple sidewalls of Rene Herse tires. Shake the sealant vigorously for 60 seconds to distribute the solids before you put it into the tire. If you follow these instructions, and bubbles still appear on the sidewalls, contact our customer service at the link below.
