Discontinued tires question.

[gthompson999]

Hi all,

My "new" car came with badly worn rears so I need to replace them with an impending track day coming up.

Current tires all around are Dunlop SP SPORT 9090. The fronts have a lot of life left in them.

It looks like this tire is discontinued.

I searched around and it seemed like mixing rear/fronts has mixed opinions.

Any suggestions on?:

1. Change them all.
2. Stay with the same family (Dunlop) but just replace the rears.
3. Put something different on the rear that is the same type of summer/extreme tire. I have Bridgestone Potenzas RE760's on my Audi which I really like but obviously that is a way different application.

Cheers

Gareth
