IMPORTANT: 10x18 forged rear must use the specific longer wheel bolts supplied with the 380 cars onwards.
At the introduction of Cup 380 a bespoke rear wheel was produced with a decreased offset to ensure that the increased width rear tyres do not contact the rear suspension/subframe. The rear wheel bolts are increased in overall length to 57mm(part number A138G6012F) to ensure full thread engagement. see Sub-sections GK.4 & GK.5 for further information.

A 'GCC Spare' wheel (Part Number: A138G0065F) also exists for Gulf State cars^[1] - for legislative reasons these cars are supplied with a spare wheel (which can be fitted to the front and rear), jack, tool kit, torque wrench, first aid kit, fire extinguisher. The wheel however has to be stored inside the cabin, meaning it isn't a practical solution to a flat tyre.

Wheel Dimensions

Details provided by Simon Bichara^[2].

Type	Standard	Cast alloy, 5 spoke-split in pairs, silver or black, 5-bolt fixing with diamond cut machine finish on the 5 radial spokes
Size	Front	7.5J x 17 H2 ET 26.3
Size	Rear	9.5J x 18 H2 ET35
Inset	Front	+ 26.0 mm
Inset	Rear	+ 35.0 mm
PCD	Front	5x110.0 ± 0.1 mm
PCD	Rear	5x114.3 ± 0.1 mm
Wheel bolts	Thread	M12 x 1.5 x 26 mm
	Torque	105 Nm
	Seat	60° taper
Centre spigot hole diameter front		65 mm
Centre spigot hole diameter rear		68 mm
Radial run-out at bead seat		0.3 mm max.
Laterial run-out at bead seat		0.3 mm max.

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.

Wheel Bolts

Wheel bolts should be tightened to 105 Nm.

Tyres

As standard the tyres on the Exige S are the following sizes:
Front: 205/45 R17 88Y, 32 psi (2.2 bar)
Rear: 265/35 R18 97Y (Corsa)/93Y (Trofeo), 38 psi (2.6 bar)

OE Fitment

As standard the Exige S comes equipped with Pirelli P Zero Corsa summer tyres.

Track focused Pirelli P Zero Trofeo tyres are also available from Lotus, combining 2 distinct tread patterns. The inner area, together with the longitudinal grooves, responds to the critical issues of wet surfaces and aquaplaning, while the outer area with pattern derived from rally asphalt applications, ensures the required rigidity to cope with the stresses during cornering, typical of racetrack driving.

For winter tyres Lotus specify Pirelli SottoZero Serie II tyres, SottoZero 210 Serie II 205/45 R17 88V M+S (33.5 psi) for the fronts, SottoZero 240 Serie II 235/40 R18 95V M+S (36 psi) for the rears. Although the rear tyres can fit the standard 9.5J x 18" rear wheels, Lotus also supply 8J x 18" rear wheels.

Alternatives

Avon Motorsport ZZR tyres are available to fit the Exige S and are used for the Exige V6 Cup and Exige V6 Cup R for the Lotus Cup UK and Europe series. The fronts are a fraction wider at 215/40 R17, resulting in a slight decrease in rolling radius for the front tyre as there is a 1.95% decrease in diameter due to the lower side profile.

Conti Wintersport TS 830P tyres are also available to fit the Exige S as an alternative winter tyre^[3].
205/45/17 Conti WinterContact TS 830P 205/45 R17 88V XL
265/35/18 Conti WinterContact TS 830P 265/35 R18 97V XL
