Valve Caps; Punctured Tyres; Replacement Tyres; Changing A Wheel And Tyre Assembly - Caterham SEVEN Owner's Handbook Manual

NOTE: Due to the minimal weight of the Caterham
it is more prone to aquaplaning in wet conditions. It
is for this reason that we recommend tyres are
changed at 2.5mm even though the legal minimum
is 1.6mm.
If tyre wear is uneven (on one side of the tyre only),
or becomes abnormally excessive, the suspension
geometry should be checked.

Valve caps

Keep the valve caps screwed down firmly. They
prevent dirt from entering the valve.

Punctured tyres

Your car is fitted with tubeless tyres, which will
normally lose pressure very slowly if penetrated by
a sharp object, provided it remains in the tyre. If
you are aware of this occurring, reduce speed
immediately and drive with caution until the spare
wheel or replacement
Remember, punctured or damaged tyres must be
permanently repaired or replaced, AS SOON AS
POSSIBLE!
NOTE: All cars are supplied with tyre fix repair
spray to repair a small puncture on the tyre surface
temporarily. Please follow the instruction on the
repair spray can.
Caterham recommend that you replace the tyre
rather than repair. A tyre repair may not withstand
the performance demands you place upon it.

Replacement tyres

Wheel rims and tyres are matched to suit the
handling characteristics of the car. Changing the
specification of a wheel or a tyre, can adversely
affect the car's handling and ultimately your own
safety in emergency road situations.
To be safe, ONLY fit replacement tyres that are
identical to the original specification shown in
'Technical data' section of this book.

Changing a wheel and tyre assembly

Tools required


Jack & handle

Wheel nut spanner
Before you start, ensure that the vehicle is on firm
level ground. Always apply the handbrake and put

Turning the jack screw by hand, raise the jack until
the centre of the jack platform fits snugly up to the
jacking point. Do not raise the car.

Removing and refitting the wheel and tyre
assembly
Before raising the vehicle, use the wheel brace to
slacken the wheel nuts ½ a turn anti-clockwise.
Ensure the jack is placed as far inboard as possible
when jacking the front of vehicle on lower
wishbone.
Attach the jack handle to the jack and turn
clockwise until the tyre is just clear of the ground.
WARNING!
 Do not allow the jack to tilt on its base.
Remove all the wheel nuts and the wheel. (Do not
place the wheel face down on the ground as this
may cause scratching to the surface of the wheel).
Replace the wheel and wheel nuts (tapered end
towards the wheel) and tighten the nuts until the
wheel is seated firmly against the hub.
