Non-RFT pressures
Ok, without wanting to start a new bun-fight, I’m going to ask “that” question
What is the recommended tyre pressure for non-RFT on my E89 35i? The RF pressures seem way too high so I was thinking around F34 R36. This is on Uniroyal Rainsport 3. Does that seem about right?

Yes, you can go higher on the rear if you carry a boot full of stuff

The only thing I keep in the boot is the roof

tyre presure is load dependant as your not altering the loading just changing the tyre use the guide on your door pillar

Id say bang on perfection with those numbers whether 18inch or 19inch , may vary a little depending on tyre brand / kind of driving you mainly do & also Re Se , Mpsort or aftermarket springs but i would expect F34 R36 to satisfy 99% of Z owners 99% of the time .Lazza wrote: ↑Sat Nov 17, 2018 2:20 pm Ok, without wanting to start a new bun-fight, I’m going to ask “that” question

Thanks Mr Wilks. A good place to start then. I’m happy to tweak them to find my own personal sweet spot, I just wanted a good starting point
While this is true, run-flats have different characteristics and requirements from standard tyres. No car the size of a Z4 should need over 40psi in non RFs!

BMW disagree with you. Read the label on your B pillar and you'll see.

F34 is a couple of pounds too low, but R36 is more than 7 out!
Don't believe me? Then ask Michelin: https://www.michelin.co.uk/tyres/car-ty ... 40-18-88-W

I might be being thick but if you follow the link it says FRONT 36.26 (36.26)PSI and REAR 39.16 (43.51)PSI. So is it 39 or 43?Busterboo wrote: ↑Wed Nov 28, 2018 3:34 amF34 is a couple of pounds too low, but R36 is more than 7 out!

If you click on the arrows, you'll see Michelin's figures are unladen and laden. They're the same front and higher rear, of course.
Unladen or not, however, they're significantly higher than recommendations in this thread.
The bottom line is that most people drive round on tyres that are too soft.

The cross/arrows don’t work on an iPad. Checking on my MacBook it actually says ‘normal use’ which with the limited ability to carry massive amounts of luggage is probably what most people would use. I agree it is higher than some have mentioned on this thread but not as high as that recommended for run flats.

Many people's logic seems to be, 'I've ditched the horrible & hard runflats. Now I can run 'normal' tyres at lower pressures.' And they then often run them too soft - 32 & 34 or 34 & 36 are quite common.
All I'm suggesting is to follow tyre manufacturers' or BMW's guidelines.

so your suggesting running the same pressures on non runflats as runflats.Busterboo wrote: ↑Wed Nov 28, 2018 12:36 pm Many people's logic seems to be, 'I've ditched the horrible & hard runflats.

the info on the door pillar is for runflats, which I assume if you follow bmw guidelines, will also be for runflats, as they are unlikely to offer advise on tyres they don't fit to the car.
