E60 M5 Tyres - Alternative to standard sizes

[AbbasSTI]

I need 4 new tyres for the standard wheels on a MY05 E60 M5. At the same time I'll be getting the alloys refurbed and powder coated.
Looking at tyre options, in standard sizes, tyres I know and like don't seem to be available.

Standard sizes being:
Front: 255/40/19 so 255÷40 = 102mm
Rear: 285/35/19 so 285÷35 = 99.75mm

I'm thinking (due to availability of tyres):
Front: 255/35/19 so 255÷35 = 89.25mm
Rear: 295/30/19 so 285÷35 =88.5mm

In the sizes I'm thinking I could get some Vredestein Ultrac Sessantas. I've had these on a different car and they were all round awesome IMO. I have AD08's on my Subaru which are also an option, and better in the dry, by the Verde's better for all year round.

This is the first time I'll be changing the tyres on the M5 and I don't want to ruin the ride.

What do people think? Stick with standard sizes? If so what brand? Or go with the Verde's.

I would stick with standard sizes.

I'll second this. They work great on my M6.

Other than ride comfort, why would you stick to standards?

Decision made, I'll go with the Super Sports from Oponeo.

Thanks for the advice,

More often than not I'd say the manufacturers, especially ones that know a thing or two about making brilliant performance cars, optimise tyre sizes for a given car quite well, no?

I wasn't arguing or being difficult I was just interested as to why the majority of answers pointed him down the line of standard sizes.

At the time of launch, BMW would have wanted to cater to the vast majority of potential clients and anyone considering the purchase of an M5, would more than likely have preferred a greater depth of tyre wall to give additional comfort.
