E39 tyre advice

[LaSource]

Hi, my M5 currently has PS2 fronts and PS3 rears. However the rear PS3s need replacing, the fronts are fine. The car only gets used for mundane road journeys - nothing extravagent in terms of performance driving.

Usually I would advocate all same tyres all round but a misunderstanding at a previous garage led to current mix match. I also find the PS3 'not a good looking tyre' (I know - silly point but they look like tractor wheels with the tread high on the sides)

I could just replace the rear with a new set of PS3s. I believe they may not be available in right sizes for the front anyway.

Alternatively, I could take the opportunity to replace all four with the same brand.

What are the current recommended tyres for this car?
My tyre place has suggested the following models:
- PS3 as stated
- Dunlop SP01
- Eagle F1

Thanks.

Excellent - thanks for that. I had not realise that Super sports were available in E39 M5 sizes.
A full set ordered for the weekend...they were actually slightly cheaper than PS3s...!
