I ran my non runflats on runflat pressures for a short while & it was all over the place, wandering on motorways and needed constant steering corrections, let several psi out (courtesy of stupot) and it's a different car

I've got 19's in 225/255 & now run 32f 35r, it's much more stable-I think the higher pressure just left a central band in the middle taking the load

"35r" That seems quite low. How many % off BMW's recommended pressure for your model is it, Rob?

45psi is recommended for the runflats from memory. as I said the car was skating round corners & lighting up the tyres in second out of slow turns

A reduction in your rear tyre pressures of 10 - one zero - TEN - psi seems a lot, Rob.

Good. I'm glad you're happy with the set-up, re-map and all.
