We cannot overemphasise the importance of keeping the tyres well pumped up: soft tyres lead to a lot more pedalling effort (which takes much of the fun out of riding), wear out quickly and puncture more easily, and have an adverse effect on handling.
Recommended tyre pressures:
Front: 75 to 90 PSI, 100 PSI max.
Rear: 85 to 100 PSI, 100 PSI max.
Front: 60 to 75 PSI, 115 PSI max.
Rear: 70 to 85 PSI, 115 PSI max.
Front: 90 to 105 PSI, 115 PSI max.
Rear: 100 to 115 PSI, 115 PSI max.
Record (used on the C Type) (*)
Front: 50 to 70 PSI, 75 PSI max.
Rear: 60 to 70 PSI, 75 PSI max.
(*) Brompton no longer makes the C Type and no longer fits Raleigh Record tyres to any of its bikes
