Tyre choices

[Ads677]

Newbie here, hello everyone.

My Michelin Primacy HP 225/50R17s 98V are almost shot and so I'm looking to replace. These must be about the most expensive tyres in the world, so which alternatives would anyone suggest and as a matter of interest would a different tyre invalidate either warranty or insurance?

Thanks in advance, Ads

Insurance and warranty - no problem, so long as they are the same size, load and speed rating.

I went for Falkens - they do a special tyre in this size for big cars/small MPVs. Can't remember the model, but were £105 each fitted through Black Circles. They're on a par with the originals for noise and grip.

How about MPG any change there ?

[chopper1192]

So far very good, no noticeable change from the originals.

As a note, 3008s seem very sensitive to tyre wear and once the originals approached 3mm they became very slippy, majorly understeery.

Do you mean in the wet only?

Surely tread depth only has a bearing in wet weather - if it never rained we'd all be using slicks...

or does the rubber harden as the tyre wears?

[colin13]

I wonder if the fact they are Low rolling resistance makes any difference ?

You may want to check out ALTENZO SPORT 225/50 ZR 17 tyres which are the correct load rating for Peugeot 3008. These retail for around £70, approximately a third of the cost of the Michelin types. You may get a couple of thousand miles less wear but at a third of the price you cannot complain.

Before having winter tyres fitted, my original tyres were down to 3mm. In both wet and dry conditions, the front tyres would lose grip when pulling away, I had problems with the steering and the front tyres skidding when braking.

When we had half and inch of snow in December last year before having the winter tyres fitted, I could not get up the hill to my house and had to fit snow socks.

OK - but losing grip in the dry had nothing to do with the depth of tread - the ONLY thing that gives grip is the rubber on the road, the grooves are only there to disperse water. If this is so, then it must mean that as the tyre wears, something happens to the rubber (hardens?) which results in lower grip.

Winter tyres are a different thing all together - of course they'll be better in the snow - what would be the point in them otherwise?

As the tyres wear there is less volume of rubber in the tread blocks. Therefore, there is less material to move and flex and the boots have problems maintaing a proper working temperature at which the compound will work effectively. It has nothing to do with the surface are of rubber in contact with the Tarmac.

Any tyre on any car is scrap at 3mm. Bin em at that point.
