Default Fitment of 20 inch rims.

I realise that the subject of fitting 20 inch rims to Gallardos has almost been done to death on this forum, and I have read most of the the threads.

However ,I am just looking for confirmation on a couple of points.

My 2006 Gallardo is currently fitted with 19 inch silver coloured Callisto rims.

I am in contact with the previous owner of the car.

He had a set of 20 inch rims made in the USA and shipped over here to the UK. They are colour coded to the car with a thin custom stripe near the outer edge of the rim which matches the yellow of the brake calipers.

I have attached a photo. Can anyone identify the make/model of the rim ?

REALLY smart, and I would like to buy them.

As I interpret the situation , fitting 20 inch rims presents no problems provided ----------

1. The profile of the 20 inch tyres is reduced so that the outer circumference of the tyre is identical to that of the 19 inch rims. This being the case there would be no adverse effect on the 4 wheel drive system or speedomoter.

2. The offset for both 20 and 19 inch rims are the same.

Are there any other points I should consider ?

Do those who have gone this route find that there has been any appreciable reduction in ride quality ?

use a tire calculator to make sure. A 245/30-20 is a tad too large for the front and may burn the diff up. A 235/30-20 is a more ideal size. It will only be .6% larger than factory, you want to stay under 1% difference.

Ray@Renown.

Thank you.

My local tyre supplier has in fact quoted as you have for the front tyres i.e. 235/30/20.

For the rears he has quoted 305/25/20.

Does that sound about right for the rears ?

It depends on how wide that rear wheel is. Do you know?

No I don't know the width of the rear wheel. I'll have to find out and get back to you.

Thank you for your help.
