Right folks,
I've currently got 275/35/20 Y(102)
But I'm looking at a set of 285 wide as my alloys are 10J which are .5 wider than stock and I'm hoping 285 will be less stretched and provide more kerb protection
My only worry is the reduced load index
The 285/30 are 21.5mm smaller in diameter and 67.6mm smaller in circumference than my current setup, faster accelerating too
Where if I stick to a 35 profile with 285/35 tyres the differences jump to 7mm larger in diameter and 22mm larger in circumference but the 35 profile offers a heavier Y(104) rating
Do I stick to 275/35 with 850kg rating each, move to 285/30 but drop to a 775kg rating but have a wider tyre and smaller rolling radius or step up to 285/35 with a 900kg rating and larger rolling radius
Hoping @RubberLover might be able to offer some assistance
It's a big heavy brute of a car weighing in excess of 2 tonne, with a bias to the front given its an Audi, a big heavy V10 sitting infront of the front wheels adding to load on the front axle
Thanks for any help
