Why a gravel tyre?

On loose gravel a narrow road tyre slides around and bounces off every stone. A gravel tyre is typically 35 to 50 mm wide, runs lower pressure and moulds itself to the surface. That gives more grip, more control and much more comfort, especially on long rides.

The tread makes the difference. A tyre with a closed centre strip and small knobs rolls fast on tarmac and hardpack. A tyre with open blocks and larger shoulder knobs bites better in sand, mud and loose corners, but hums on tarmac and rolls slower. What you choose depends on the mix of paved and unpaved in your rides.

Almost all gravel tyres are designed to run tubeless. With sealant and a pressure of roughly 1.5 to 2.5 bar (depending on width, your weight and the terrain), you get grip and comfort, and thorn punctures often seal themselves. Heavier tyres with reinforced sidewalls resist sharp stones better, but cost weight.

If a wider tyre fits your frame, it is often the best upgrade for a gravel bike. Measure the clearance at the chainstays and the fork before you choose.

Gravel tyre width and pressure

Starting values for tubeless at a rider weight of about 75 kg. Adjust for weight, rim width and surface.

Width	Suits	Pressure (approx.)	Rolling speed	Grip and comfort
35 to 38 mm	Mostly paved, hardpack	2.3 to 3 bar	Fast	Decent
40 to 42 mm	All-round gravel	1.8 to 2.5 bar	Good	Good
45 to 47 mm	Technical gravel, bikepacking	1.5 to 2.2 bar	Average	Very good
50 mm and wider	Rough terrain, heavy loads	1.2 to 2 bar	Slower	Maximum

Check how much room your frame has first. Beyond its maximum width the tyre will rub on the frame or fork.

Choose it if

You prefer a simple setup with an inner tube.
You are comparing the same tyre from another seller.
You ride gravel, forest tracks and farm roads as well as tarmac.
You want more comfort and grip than your road tyres give.

Choose something else if

For sealant and lower pressures, choose a tubeless tyre.
You ride almost only on tarmac: a road tyre is lighter and faster.
You tackle technical climbs and descents over roots and rocks: an MTB tyre grips more.

How to choose and use gravel tyres

Measure your clearance
Check the maximum your frame and fork allow. A tyre’s real width often differs from its label, so leave at least 4 mm of clearance.
Pick the tread
Lots of tarmac and hardpack suits a fast-rolling tread. For sand and mud, choose open knobs.
Fit and seat tubeless
Fit the tyre on a tubeless-ready rim, add sealant and inflate hard until the beads pop into place. A compressor or tubeless booster helps with a stubborn tyre.
Start with low pressure
Ride a first loop and drop 0.1 to 0.2 bar at a time until it feels comfortable without bottoming out on the rim.
Adjust for the surface
On loose ground you can run lower; on hard, sharp stone go slightly higher to protect the rim.

Good to know

Compare size and variant with the first Override page before choosing.
Check your rim width.
Sealant dries out after a few months. Check it and top it up regularly.
Too low a pressure causes rim strikes and can make the tyre burp off the rim in corners.
Check that rim and tyre are truly tubeless-ready and follow the same standard.
An aggressive tread adds rolling resistance on tarmac. You may swap tyres by season.
