The tyres are quite new, but worn differently according to the
Advanced AA check I had done. The tread depths ( I presume the
miniumum found) ranged from 4-8mm. I got one depth for each tyre.
Two tyres are Star-Millenium (?) and I think two are Bridgestone. They
all are 215/45/ZR17.
One question, how do I know the alloys fitted are the same width as
the tyres fitted to them? I have the double 5 spoke alloy types
presumably fitted when the car was bought new.
I recently bought a tyre gauge from Halfords (a hand held digital one
you just press into the valve). All tyres were 30 or 31 psi. The gauge
says its readings are accurate to +/-1 psi.
I haven't looked at how they are wearing. I suppose I'll just wait
until my first service as owner and see what they say in general about
the steering/alignment/wear/tyres etc. Then try and correlate that to
what I was told when I bought it and when the AA Check was done.
The car has done 90-110mph on motorways for extended periods of time
now and steering feels OK.
I think that at lights you could be right and that it is hopefully
just uneven tarmac. Sometimes though I do get a distinct pull on the
steering wheel just before the car stops, so it doesn't move the car
dangerously but the steering wheel angle alters by a good 20 degrees.
It's as if the brake on one side has stopped that wheel dead and the
other is still turning so you'd get 'pull' to the stopped side
wouldn't you?
I'll try the 32psi for a few weeks anyway and keep you posted on the
outcomes of any future service. It's just bugging me that I don't know
any definite answers or if indeed there are any definite problems.
Robert.
