jst wondering this morning because they look slightly flatter this morning after not driving the mini for a few days and she's more comfortable but not god the handling feels iffy
Tyre pressures always go down in cold weather, especially cold mornings. Once late Autumn arrives you'll find the pressures a few PSI down if you've not pumped them up to compensate. Set to about 33 psi all round and see if that helps.
We all seem to like different pressures. I used to run 30/28 or 32/30 on the old 145 section tyres, but I think, and I know it's a personal thing, that 32 all round works better with a 165 section tyre, in both 10" and 12" diameters.
