What are the quietist Tyres for an Ocatvia RS

You are correct on all counts.
If the figures i posted had come from any other wheel aligner I'd have said they were a load of tripe. From this guy though, he'd be near the money. Geebuz, you should have seen what he used to set-up W124 Mercedes with. I learnt so much from him & became so good at wheel alignments that I was head-hunted into aircraft maintenance by one of my clients (who reckoned I was the only person between mascot & Gosford that could do his alignments properly - he had tried a dozen "specialists"). This guy is an excellent driver - one of the few that I can relax enough to have a sleep instead of crapping my pants. We used to race together & his feel for what the car was doing & how the chassis was reacting was several levels above me (bastard!).

I can understand what he is doing with his big toe-in figures but it would all centre around tyre wear & how the car drives. I don't think he's done many Octavias & I'm guessing his assumption is there isn't any adjustability in the camber (is there? Front doesn't look good). There might not be adjustment bolts but there may be some areas of slop in the suspension to undo bolts, move a component & tighten again. My Gen2 Liberty had about half a degree movement available in the rear suspension bolts despite having "no adjustment".

From your figures (I think I have this right), front camber is -0.6deg +-0.5 which would be much better if you tended to run a lot of straight roads. if you were running the wheels relatively upright like this, then toe-in would be far less severe. i have no idea how to convert degrees of toe to mm.

your rear camber (I think) is -1.75deg +-0.5 and if the adjustment is there, I'd be going as upright as possible for the reasons you stated. Again, get the wheel upright & the toe can be wound back a bit.

It really depends how you drive - if your like me & trundle up/down the M5 most days then you have to be conservative. If you are lucky enough to have to do the twisties fairly often then you can afford to run a bit more -ve camber.

And there was me thinking that tyres were round rubber things more or less in the corners of a vehicle that rotated for several tens of thousands of km then wore out and were replaced.
