A sticker with the code number is supplied with the vehicle for safe keeping by the vehicle owner. This
code will enable dealers to order a replacement coded extension tool if necessary. It is the responsibility of the
dealer to verify the legitimacy of any customer request for a coded tool. Typical security code; FEOR17025
GH.3 - TYRES
Elise 111R prior '06 M.Y.: Lotus engineers worked with the tyre manufacturer Bridgestone, to produce a version
of the 'Potenza RE040' tyre specifically for the Lotus Elise 'Mk.2' including Elise 111R, to optimise performance
on both road and track. This tyre is identified by the construction code element of the DOT code moulded on
one of the tyre sidewalls, and it is most important that ONLY this version is fitted if the correct handling char-
acteristics are to be maintained.

At the introduction of the 111R, the speed
rating of the tyres was uprated from 'V' to 'W',
without any physical change to the construc-
tion. For legal reasons, only tyres marked with
a 'W' rating should be used on the 111R.
Wear indicators are moulded into the bot-
tom of the tread grooves at intervals around
the tyre, indicated by small pointers on the
outer tread blocks.
The tyres should be replaced before being worn to this minimum legal tread depth. Note that the 'Potenza'
tread pattern is directional, so that the tyre must be fitted onto the wheel with regard to which side of the car the
wheel is to be fitted. A direction of rotation arrow is included in the tyre sidewall markings.

Exige & Elise Option: These models are
fitted with Yokohama A048 tyres, which have
been developed jointly by Lotus and Yokohama
to suit the requirements of the performance
driver, with special emphasis on track use.
Compared with the standard tyre, the
front tyre width is increased and the profile
reduced from 175/55 to 195/50. The tyre
tread design is directional, such that each
wheel/tyre assembly is dedicated to a single
vehicle corner. The Lotus specific construction
is identified by the letters 'LTS' moulded on the
tyre sidewall. Ensure that any replacement
tyre is so marked.
On Elise models, in order to maintain sufficient vehicle stability with these track based tyres, Lotus approves
of A048s only in conjunction with sports suspension. The tyres should not be fitted on standard specification
wheels, or with standard suspension.
