Hi Folks,

We were discussing this on an FB group for Huracan owners about tire replacements etc.

So usually you would try to match the front and rear circumferences to match as close as possible or somehow measure actual rolling diameter.

So based on simple circumference for OEM front 245/30/20 and rear 305/30/20 it comes to:

Front: 81"
Rear: 85.4"

Around 5% difference. That seems excessive?
Why not use a different front aspect ratio or larger front width?

If this is fine or if the AWD can somehow manage this difference, when replacing with aftermarket wheels, should we match the 5% difference. Even dynamic AWD systems usually want similar circumferences.

Thoughts?
