Wheels; Wheel Bolts; Wheel Alignment & Tire Balance - Lotus ELISE 2007 Owner's Handbook Manual

Wheels

Ensure that only original equipment, or Lotus approved wheel
and tire combinations are fitted. After the car has been used on
track, or in competition conditions, the wheels should be removed
and thoroughly inspected for damage.
WARNING:
After striking a pothole or kerb, the wheels should be
removed and the wheel and tire thoroughly inspected for
damage. Renew the wheel and/or tire if necessary. Safety
considerations should always be paramount and new parts
fitted in any cases of doubt.

Wheel Bolts

The wheel bolts used on the Elise/Exige are of a special
design to suit the small diameter fixing tunnels in the wheel
centres. The bolts have a 10 spline socket head, for which a
special extension tool is supplied with the car. A 17mm a/f deep
socket and 1/2 inch square drive wrench should be applied to
the extension tool, with a tightening torque of 77 lbf.ft (105 Nm)
required.
To protect against wheel theft, one of the four bolts securing
each wheel may be key coded, requiring a correspondingly coded
socket wrench and 1/2 inch square drive extension. Rotate the
coded socket until full engagement with the bolt head is ensured
and take care to maintain the extension tool perpendicular to the
wheel face before applying release torque.
NOTICE: It is not recommended to use hammer action air tools
on the coded bolts - use only manual tools.
Both the standard extension and (if applicable) coded socket
tools are stowed in the car tool kit, and should remain with the
car at all times to ensure that servicing may be performed. The
key code included in the tool kit should be recorded and kept
safely with the car documents, in case a replacement socket tool
needs to be ordered.
Wheel Alignment and Tire Balance
The wheels on your car were aligned and balanced carefully
during the manufacture of your car to give you the longest tire
life and best overall performance.
