Dear all

i am knew to the forum as I am just buying my first lambo gallardo ( to be delivered in June 2008 ).
Is there any problem upgrading the rear tyres of the gallardo spider 2008 from 295/30/19 Y Pirelli PZero on 11x19 rims ( original equipment) to the 305/30/19 Y Pirelli PZero on the same rims.
The difference in diameter,circumference is only 0.9%, well below the maximum 2.5% maximum recommended change.
However, the official dealership refuses to do it?
Any problems anticipated with factory warranty?
Any problems anticipated with handling, traccion control,ESP....?
Thanks

What's the purpose of doing this, pray tell ?

Pirelli PZero corsas come with lateral wall reinforcement.
This would improve handling under heavy cornering by reducing tyre deformation.
The slightly wider tyres would also give a better looking rear aspect for the car ( in my opinion ).
Standard Pirelli PZero tyres in G are well known for their poor performance and to prove the point; G Superleggera comes with Pirelli Corsas and according to review articles this is helping the handling of the car even more than the slighly reviewed rear suspension stting in the car.
