With 10” A008’s, for street use, is there any reason to run a higher tire pressure than the recommended 28F/26R?

I'd start at 28 front and 30 rear, if you feel it's not right drop to 26/28

No, in a word.

 

Higher pressure should reduce the rolling resistance a little, but keep an eye out for uneven tyre wear.

If I remember rightly from our old Michelin tyre pressure chart, the mini specials and early 80's mini sprites that were factory fitted with 165/70/10's were 2 psi lower all round than a 145/10, so 26 front, 24 rear.
This is what I run.

I would never run higher at the rear.

 

for every day driving 28/26 is fine.

oops, so 30psi (cold) all round on 10" Yoko AO32R (soft) is too much?

Generally 30 psi is about right imo, if you find it's too hard you can reduce as needed, also keep an eye on tyre wear.

All my minis are set differently

My 998(165/60/12 tyres)is on 26 all round due to very tired suspension components (it's getting restored soon)

My estate (145/10 Falken tyres) is set at 28 front and 30 rear

The 1275 Saloon(165/60/12 tyres) is at 28 and 30, if I need to I will drop the pressures to suit

It feels fine, I adjusted the dampers a bit softer too (8 way), I know it sounds stupid but they always look flat-ish ie bulge at the bottom... compared to wifes car (E220) that are solid @34psi. 30 measured with accurate dial cold will do for now then on mine!

I use 30 psi all round with A008's. It works well for me.

30 psi is what my friend runs on his A008 tyres, try it and go from there, if it's too hard, drop to 28 psi

Interesting- my Haynes manual quotes 1.7 bar, front and rear for the 165/70 x 10. Guess it comes down to handling and ride comfort.
