CTR Tyre Pressure Calculator — Professional MTB Tyre Setup & Tyre Finder Tool

Stop guessing your tyre pressure. Get the exact number for your weight, tyre, rim and terrain.

The only MTB tyre tool that calculates pressure AND finds your perfect tyre.

 

Every rider knows tyre pressure matters. Too high and you’re bouncing off every rock. Too low and you’re burping sealant in corners. The right pressure changes with your weight, your tyre, your rim width, your inserts, your terrain and even the weather. The CTR Tyre Pressure Calculator works all of this out for you — instantly.

 

TWO TOOLS IN ONE

 

Mode 1 — Calculate pressure for your current tyres

Select your brand and model from our database of 10 brands and 50+ models. We show you the manufacturer’s recommended PSI range alongside our calculated starting pressure — so you can see exactly where our formula sits against the brand’s own spec. Then fine tune from there.

 

Mode 2 — Find your perfect tyre AND pressure

Don’t know what tyre to run? Tell us your riding style, terrain, priorities and max tyre width your bike can fit. The finder scores every tyre in our database against your inputs and ranks the best options — with front and rear recommendations paired specifically for your setup.

 

WHAT GOES INTO THE CALCULATION

 

Every variable that affects your tyre pressure is accounted for:

 

• Rider weight including gear, pack and water

• Tyre brand, model and width

• Inner rim width — from 20mm XC race to 39mm plus bikes

• Tubeless, tubed butyl or tubed latex setup

• Tyre insert — 9 types including CushCore XC, Trail and Pro, Panzer, Vittoria Air-Liner, Rimpact, Tannus and more

• Tyre casing — from XC single ply through to DH dual ply

• Riding discipline — XC racing through to downhill

• Terrain conditions — hardpack, loose, rocky, loamy, wet and mud

• Speed vs grip priority slider

• eMTB flag — automatically adds 3 PSI for the extra weight and motor torque

FRONT AND REAR SPECIFIC PAIRING

 

Where brands make dedicated front and rear tyres, the finder recommends them as a pair — Minion DHF front with DHR II rear, Newton MTF front with Newton MTR rear, Butcher front with Eliminator rear. It then explains why the pairing works for your riding style.

 

After seeing your recommendations you can tap any brand to filter results to that brand only — useful if you have a preferred brand or your local shop only stocks certain tyres.

 

MANUFACTURER PSI VERIFICATION

 

When you select a specific model in pressure mode, the tool shows the manufacturer’s own recommended pressure range alongside our calculated PSI. This gives you full confidence in the number — you can see exactly how our formula compares to the brand’s spec.
