Michelin Tire Pressure — Correct Pressure for Michelin Bike Tires
Michelin Power Cup road race runs 60–80 PSI tubeless or 85–105 PSI tubed. Power Road in 700×28c runs 80–115 PSI tubed. Power Gravel 700×35c runs 30–50 PSI tubeless — the 43 PSI sidewall minimum applies to tubed use only. Force XC MTB runs 22–30 PSI tubeless. Force AM all-mountain runs 20–27 PSI tubeless. Wild Enduro runs 18–25 PSI front, 20–27 PSI rear tubeless. Michelin's free online bicycle tire pressure calculator at michelinman.com/bicycle generates a personalised recommendation by wheel size and rider weight.
Michelin Bicycle Tire Line — Racing, Competition, and Country
Three product tiers with different casing constructions and pressure profiles across road, gravel, and MTB
Michelin's bicycle tire range is organised around three performance tiers: Racing Line (lightest, highest TPI, performance-first), Competition Line (balanced weight and durability), and Country Line (commuter and value tires). These tiers share the same core design but differ in casing density, sidewall rubber thickness, and puncture-protection layer placement.
Racing Line
Racing Line tires use Michelin's highest TPI carcass available in bicycle tires. The sidewall is lighter and more supple, which allows the casing to conform to the road surface at lower pressures. Power Cup Competition and Power Race TLR fall in this tier. On tubeless-compatible Racing Line tires, you can safely run 8–12 PSI below the printed minimum because the tubeless air volume and the supple casing combine to prevent pinch flats without a tube.
Competition Line
Competition Line covers the majority of Michelin bicycle tires: Power Road, Power Endurance, Force XC Competition, Force AM Competition, and Wild Enduro Competition. Standard TPI construction with a tougher outer casing compound. Pressure ranges on Competition tires are slightly narrower at the low end than Racing Line equivalents.
GUM-X MTB Compound
Michelin's GUM-X compound appears on Force AM and Wild Enduro MTB tires. GUM-X is a softer, stickier rubber formulation designed for wet rock and root grip. Like ADDIX or MaxxGrip on competing brands, GUM-X does not alter the recommended pressure range — it changes the grip characteristics at any given pressure. Do not run lower pressure specifically because a tire uses GUM-X; follow the casing width and rider weight guidance instead.
Michelin Road Tire Pressure
Power Cup, Power Race, and Power Road — high pressure road tires, tubed or tubeless
| Model | Width | Setup | Min PSI | Max PSI | Notes |
|---|---|---|---|---|---|
| Power Cup Competition | 700×25c | Tubed | 87 | 120 | Road race |
| Power Cup Competition | 700×25c | Tubeless | 65 | 90 | TLR |
| Power Cup Competition | 700×28c | Tubed | 80 | 110 | Road race |
| Power Cup Competition | 700×28c | Tubeless | 60 | 85 | TLR |
| Power Race | 700×25c | Tubed | 90 | 125 | Track / race |
| Power Race | 700×28c | Tubed | 83 | 115 | Road race |
| Power Road TLR | 700×28c | Tubeless | 65 | 90 | Road training |
| Power Road TLR | 700×32c | Tubeless | 55 | 80 | Road / light gravel |
| Power Endurance | 700×28c | Tubed | 80 | 110 | Training / endurance |
| Power Endurance | 700×32c | Tubed | 70 | 100 | Training |
Michelin provides width-specific pressure tables in the product packaging. The figures above are from current production runs — older tires may carry slightly different ratings. Hookless rim users must cap pressure at 72.5 PSI (5.0 bar) regardless of sidewall print on any Michelin road tire mounted on a hookless rim.
Michelin Gravel Tire Pressure — Power Gravel and Power All Road
Power Gravel — the sidewall minimum is for tubed use only; tubeless users ride lower
| Model | Width | Setup | Riding PSI | Notes |
|---|---|---|---|---|
| Power Gravel | 700×35c | Tubeless | 30–50 | Sidewall min 43 PSI (tubed only) |
| Power Gravel | 700×40c | Tubeless | 26–46 | Mixed gravel |
| Power Gravel | 700×45c | Tubeless | 24–42 | Adventure gravel |
| Power Gravel | 650b×47c | Tubeless | 22–40 | Bikepacking |
| Power All Road | 700×40c | Tubeless | 28–48 | All-road / gravel |
| Power All Road | 700×45c | Tubeless | 25–44 | Rough gravel |
| Power All Road | 650b×47c | Tubeless | 22–40 | Bikepacking |
The most common mistake with Power Gravel is honouring the 43 PSI sidewall minimum when riding tubeless. The sidewall figure is a tubed structural limit — without a tube, the sealant-filled air volume eliminates pinch flat risk and the casing can operate safely at 25–30 PSI. Experienced gravel riders routinely run Power Gravel at 28–35 PSI tubeless and find it transforms the tire's ride quality and grip on variable surfaces.
Michelin MTB Tire Pressure — Force and Wild Series
Force XC, Force AM, Wild AM2, and Wild Enduro — each model is designed for a specific pressure window
| Model | Width | Casing | Discipline | Tubed PSI | Tubeless PSI |
|---|---|---|---|---|---|
| Force XC | 29×2.1 | Competition | XC | 30–50 | 22–30 |
| Force XC | 29×2.25 | Competition | XC / trail | 28–48 | 20–30 |
| Force XC | 27.5×2.25 | Competition | XC | 28–48 | 20–30 |
| Force AM | 29×2.35 | Competition | All-mountain | 26–45 | 20–28 |
| Force AM | 27.5×2.35 | Competition | All-mountain | 26–45 | 20–27 |
| Force AM | 27.5×2.6 | Competition | All-mountain | 24–42 | 18–26 |
| Wild AM2 | 29×2.4 | Competition | All-mountain | 24–42 | 18–26 |
| Wild AM2 | 27.5×2.6 | Competition | All-mountain | 22–40 | 17–25 |
| Wild Enduro Front | 27.5×2.4 | Competition | Enduro / DH | 22–38 | 16–24 |
| Wild Enduro Rear | 27.5×2.4 | Competition | Enduro / DH | 24–40 | 18–26 |
| Wild RockR | 27.5×2.5 | Competition | Enduro | 22–38 | 17–25 |
Michelin designs front and rear MTB tires separately. Wild Enduro Front uses a taller, more open tread pattern optimised for steering traction at lower pressures. Wild Enduro Rear uses a denser tread for braking traction and wear resistance. Run the front 2–3 PSI lower than the rear to maximise front-end grip without sacrificing rear support.
How to Use the Michelin Bicycle Tire Pressure Calculator
Michelin's free calculator generates a personalised PSI based on tire size, rider weight, and tube setup
Michelin provides an official online bicycle tire pressure calculator at michelinman.com/bicycle. The tool asks for:
- Tire width in mm — found on the tire sidewall (e.g., 35 for 700×35c)
- Rider weight in kg or lbs — body weight only, not including bike weight
- Setup — tubed or tubeless
- Rim type — standard hooked or hookless
The calculator outputs a specific PSI recommendation for both front and rear. Michelin's tool reflects the same physics as professional fitters use: wider tires run lower pressure, heavier riders run higher pressure, tubeless setups run lower than equivalent tubed.
For riders who want a simplified rule without the calculator: take the printed sidewall minimum, subtract 15% for tubeless, then add 2 PSI for every 10 kg of body weight above 65 kg. This formula produces results within 2–3 PSI of the Michelin calculator output for most combinations.
Rider Weight Adjustment for Michelin MTB Tires
Michelin's midpoint PSI figures assume a 75 kg rider — adjust proportionally for your weight
| Rider Weight | Force XC 29×2.1 | Force AM 29×2.35 | Wild Enduro 27.5×2.4 |
|---|---|---|---|
| Under 60 kg | 20–24 PSI | 17–21 PSI | 15–20 PSI |
| 60–70 kg | 22–26 PSI | 19–23 PSI | 17–22 PSI |
| 70–80 kg | 24–28 PSI | 21–25 PSI | 19–24 PSI |
| 80–90 kg | 26–30 PSI | 23–27 PSI | 21–26 PSI |
| Over 90 kg | 28–32 PSI | 25–29 PSI | 23–28 PSI |
These figures are tubeless. For tubed, add 8–10 PSI across the board. Terrain matters as much as weight: in loose soil, wet roots, or slippery rock, use the lower end of the range for your weight class. On hardpack or dry summer trails, use the upper end for roll speed and support.
Frequently Asked Questions
What PSI for Michelin Power Gravel in 700×40c?
Michelin Power Gravel 700×40c runs 26–46 PSI tubeless for most gravel conditions. The printed sidewall minimum of 43 PSI applies to tubed operation only — tubeless riders safely run 28–38 PSI depending on terrain and rider weight. A 70 kg rider on mixed gravel typically runs 30–35 PSI tubeless. On full loose gravel, 26–30 PSI maximises grip.
What PSI for Michelin Force XC MTB tire?
Michelin Force XC in 29×2.1 runs 22–30 PSI tubeless. A 70–75 kg rider on typical XC terrain starts at 24–26 PSI and adjusts by surface: 22–24 PSI on loose or wet terrain, 26–30 PSI on hardpack or clay. Tubed, add 8–10 PSI to these figures. The Force XC was designed as a tubeless-first tire — running it with a tube negates most of its performance characteristics.
What PSI for Michelin Wild Enduro tires?
Michelin Wild Enduro Front runs 16–24 PSI tubeless and Wild Enduro Rear runs 18–26 PSI tubeless. Most riders set the front 2–3 PSI below the rear. A 75 kg enduro rider typically uses 18–20 PSI front and 22–24 PSI rear on typical enduro terrain. Increase rear to 25–26 PSI for high-speed hardpack runs.
Does Michelin's bicycle tire calculator work for all tire sizes?
Yes. Michelin's calculator at michelinman.com/bicycle covers all Michelin bicycle tires including road (700c), gravel (700c and 650b), and MTB (27.5 and 29 inch). The tool generates front and rear recommendations separately. It does not cover non-Michelin tires — for those, use the BikePSI calculator and apply the width and weight adjustments.
What does the sidewall minimum PSI on Michelin tires mean?
The sidewall minimum is a structural safety threshold for tubed operation. Below this pressure with a tube, the casing cannot support the load and pinch flats or casing damage become likely. For tubeless riders, the minimum does not apply in the same way because there is no tube to pinch. Tubeless operation can safely begin 10–15 PSI below the printed minimum. Always use sealant when running below the sidewall minimum tubeless.
What is GUM-X compound and does it change tire pressure?
GUM-X is Michelin's grip-optimised rubber compound used on Force AM and Wild Enduro tires. It is softer and stickier than the standard compound, improving traction on wet rock, roots, and technical terrain. GUM-X does not change the recommended pressure range — a Force AM GUM-X and a Force AM Competition carry the same PSI guidance. Compound choice affects grip at a given pressure; width, casing, and rider weight determine what that pressure is.
Can I run Michelin road tires on hookless rims?
Yes, if the tire is ETRTO TLR-rated. All current Michelin Power Road TLR, Power Cup Competition TLR, and Power All Road tires are hookless-compatible within the ETRTO 72.5 PSI / 5.0 bar maximum. Check the Michelin product page to confirm TLR certification before mounting on hookless rims — older models may not be rated for hookless use.
