After a bunch of trouble with my V35 sedan:
* When bought, mismatched tyres all round, various states of wear
* Offset all wrong, alignment stuffed: tramlined like a little so-and-so, steered like a barge
I had the staggered Arthur Exchange 18" rims machined (to correct the offset), all new rubber, full balance, alignment and suspension/steering setup done.
Lasted 8 months before I somehow suddenly got a bent rear passenger rim, and on inspection, 3 of the 4 tyres were delaminating.
Time for this setup to go. I'm very out-of-pocket at this stage.
* Bought some used 18" 350Z rims, with 50% RE040 all round.
* Had them balanced and fitted
"Floaty" driving feel, looked like the tyres were "stretched" on the rim (225/45R18)....lasted 4 months before the rubber was worn right down.
Oops, now I need rego. And 4 new tyres. Right now.
* Settled on Nexen N8000 (yes, yes, they're no P-ZEROs) for $135 each shipped (235/40R18).
* Had them fitted by the local guys in my suburb, balanced, and a 4-way "supardupar with laser beams OMG!" alignment done
Done 500km so far, and they're quiet, steer nicely, and I hope my tyre saga is over. Or else I think I'm being divorced! :-(
