    I've got 4 (surprisingly) Maxxis 205/45ZR17 84W tyres on my mini. The missus is out in it and thinks she needs to pump up the tyres. What should the PSI be for them??

    Can't go wrong around the 34-38 psi mark. I always run around these levels.

    If you're pumpin them up to that pressure, which IMO is a tad high (I run my non-runflats at about 32psi) keep an eye on how the tread wears You may find it wearing more in the centre

    no lots of wearing on the edges still To be honest I normally run 34psig not too big a difference, only put them up another 2-3 when running fully loaded.

    In one thread, you slate people for driving quick, now you're telling him he doesn't drive around corners quick enough?! Bizarre!

    Aside from anything else, lower tyre pressures will provide more grip. If you think he's not going round corners quick enough, and he has 32psi in his fronts, explain why the race mini's go out with 25 or so in their front tyres, and corner like they do?

    On non-run flats, i'd stick with 30-32 ish, the runflats require a slightly higher pressure to fill out the centre of the tyre and stop the shoulders wearing so much, as the sidewalls are much stiffer.

    38psi seems very high to me though, for a road car, that you want to grip. Must be interesting in the wet. Try loosing a few pounds out them and see what you think, they will be more compliant, the ride will be nicer too, and they will provide a bit more grip.

    Our mini with it's horrible horrible run-flat 17's hovers around the 34 mark, i refuse to put them any higher, and even at that, they feel too high. If we keep it long enough, the run flats are going and i'm putting bridgestones or something decent on it.
