Hi

To anyone running P Zero Neros, are they directional? I need to be able to roatate tyres for maximum life as this is a driving instruction car.

Chris

I think they are assymmetrical i.e they onyl fit to specific side of car.

Errrrrrrr no they are not directional they are assimetrical...........

This means they have an inside and outside edge, they can go anywhere on the car because its how they are fitted to the wheel that counts...downside is they cannot be turned on the wheel

New tyres should go to the rear anyhow and it is not reccomended to turn tyres around...i.e if you want to swap tyres around do front to backs only on the same side because if you swap n/s to o/s the tread will have been used to running in one direction and have worn accordingly..

Hope this helps ..PM me if u want

I second that.

Once switched (rotated) some Dunlop SP's years ago, on a Mk3 Cortina, so they were all spinning the opposite direction to that which they had previously been running. Gripped allright for normal motoring but the road noise level rocketed.

Sounded like all 4 wheel bearings on their way out until I put the wheels back as was.

You live and learn.

eh? never heard that last bit before and it doesnt sound right at all.and hes not talking about putting new tryes on hes talking about switching them round.

I agree dont put nnice new ones on front and leave snotters on the back cos it'll bite yer bum.

but there no harm in putting you front on the back so they all wear out at the same time.

That's right front to back, no problem, but 'rotating' your tyres left to right etc would mean the tyre running backwards to how it had originally worn... which is bad news :thumbdwn:

Hi

I think you can get away with it with some tyres and not with others. I have rotated the Conti Sport Contact II as I dont intend replacing them with the same, so want to wear out all 4 evenly. These are OK reversed, although you do get a little more tyre squeal than before when really pushing it, the car still handles and grips fine. If I am staying with the Neros, I would just wear the fronts out and bring the rears forward, replacing two at a time for the duration of ownership of the car.

What sort of prices are we seeing for the Neros? I have been offered

If that's fitted, I wouldn't imagine you could get them much cheaper!

Yep, fitted balanced and with VAT.

Might try a mate to see if he can beat it. Usually gets me tyres for less than anyone else round here by some margin.

That is a good deal, I paid just under

:P Mate, regardless of new tyres to the rear, just an advisable point on my behalf what i am saying IS if a tyre has been on the nearside for X amount of miles it will have worn to that direction of travel....if you then put it on the offside the direction of travel would have changed and there is a likelyhood of the tread having slightly raised edges resulting in more road noise......comprendeeee:mad:

Hi Phil

The tyre noise in this instance did not increase at all. The Contis dont have much in the way of lug edges anyway, but it could be a problem with some tyres. What is possible is that the tyre carcass will have settled into a particular mode and reversing the tyres direction of rotation may cause a loss of rigidity in the sidewalls as they are working in a different mode. As I sad, I seem to have got away with it on the Contis but it is not something I would normally do.

About putting new tyres on the rear, I thougth it was the other way arround.

The Front tryres do most the braking, adn our cars are designed to oversteer, so the best gripping tyres should be on the front. besides, having a puncture, or a blow out on the front would also be more dangerous IMO.

Michelins idea after lots of testing, all major manufactures have now followed suit " BEST TYRES TO REAR GUYS" More tread on the rear is better because you are not in control of the back end....doesn`t matter what you have on the front,half worn, new, bald you are in control of it with the steering

Pop into my works and i`ll show you the wallchart:P
