Note that the inset figure is the displacement of the wheelrim centreline relative to the wheel/hub mounting face. A positive inset indicates that the wheelrim centreline lies inboard of the wheel mounting face, whereas a negative inset means the wheelrim centreline is outboard of the mounting face.
The wheel bolts used are of a special design to suit the small diameter fixing tunnels in the wheel centres. The bolts have an M12 x1.5 thread, 60° conical seat, and a 10 spline socket head for which a special extension tool is supplied with the car.
A 17 mm a/f deep socket and 1/2 inch square drive torque wrench should be applied to the extension tool, with a tightening torque of 105 Nm required.
To protect against wheel theft, one of the five bolts securing each wheel is key coded, and requires a correspondingly coded adaptor tool. Fit the adaptor tool onto a 1/2 inch square drive extension, and rotate the adaptor until until full engagement into the bolt head is assured before applying torque. Note that an alignment mark is provided on the coded bolt head and adaptor tool to aid refitting. The spline drive extension and the coded adaptor tool are stowed in the vehicle tool pouch, and should remain with the car at all times to allow servicing or repairs to be performed.
The Part No. for the wheel bolts is A132G6002F.
The Evora is supplied as standard with Pirelli P-Zero tyres. The fronts are 225/40 ZR18, the rears are 255/35 ZR19. Pressures as listed in the owners manual are front 33psi, rear 36 psi. This is increased to 40psi and 43psi if the car is heavily loaded. Pirelli produce different compounds for different manufacturers - for the Evora MO compound tyres are used on the front and MO1 for the rear.
If you opt for the larger diameter Design wheels then tyre sizes are increased to 235/35 R19 for the fronts and 275/30 R20 for the rears, with Pirelli P-Zero Corsa's becoming the standard fitment.
Winter tyres are also available from Lotus in the form of the Yokohama W. Drive V902 'LTS'. These are 215/40 R18 on the front, 245/35 R19 on the rear and use the same pressures as the standard Pirellis.
Yokohama Advan Sport AD08's are also available to fit the Evora. Yokohama's were used during the cars development before switching to Pirelli P-Zeros for production.
As of 2013 the Lotus Cup UK and Europe series, which feature the Evora GTS, GTN and GT4 race cars, make use of the Avon Motorsport ZZR road legal tyres in conjunction with the 18" Rimstock wheels supplied by Lotus Racing.
