TYRES !!

[dgrewar]

Afternoon All

Considering 4 new tyres.
Good pass on recent MOT. One advisory was back tyres showing wear and shredding.
Best tyres for my '89 944 2.7?
Same fronts as rears?

Advice, as always, greatly appreciated!

Front and rears should be same brand and model, although often staggered if that's what you mean? Best is subjective but for your 2.7 I would go for the Falken 452, its a grippy, progressive tyre thats very good in the dry and not bad in the wet. One of the best value tyres out there IMO.

Or if you want the Porsche recommended tyre for your car then here.

Dont fit the Porsche N rated Pierllis, theyre awful!

 

[Copperman05]

I know the P6000's are pretty [:'(] but the P Zero's too?

[944 man]

I presumed that only the P6000s were available in 15"? If the car has non-standard wheels then theres no reason that I can think of to worry about N ratings. Most cars with 911 or Boxster wheels are terribly incorrectly tyred, N2 or not...

+1 on the Falken 452

What is it with peoples fascination for Porsche N rating on 25 year old vehicles!!

Why worry about it, its the size, load and speed rating you need for the wheels and car you have thats all - whatever else is up to the individual.

Porsche`s N ratings are recommendations and only that or you`d all be fitting the original tyres if they were in manufacture (not) or scrapping the car.

And it is debatable if "N" tryes have any bearing on our conventional cars. My understanding is N tyres came about because the standard version didn't perform well on the 911. To get around this they produced the N tyres. How they differed I don't know but were better on the 911. My supposition is the fronts were a softer compound because the (old) 911 doesn't have the same weight loading front to back as a conventional car.

What ever. I rate Falkens as well and a much better/cheaper option than Conti's.

 

[andy watson]

Had Conti's on my 18"s and now P6000's on my 16"s no problem for me!

So to sum up......

18" wheels on a 944...a real no no!

P6000 tyres...a real no no!

Nothing like bucking the trend [][]

I believe Porsche introduced the N rating thing when they noticed some tyres did not have enough of stiff sidewalls to compensate for the relative pendulum effect due the engine's location. Some may argue that 924/944 should not suffer from this issue to the same extent as a vintage 911, but considering the high polar moment of inertia typical of our cars the rear end can become a bit lively even in unexpected conditions.

It may less be critical these days as most performance cars run (very) low profile tyres but that is not the case when most of us are still running 15" or 16" tyres. The higher the tyre profile, the quicker the issue may arise.

Porsche recommend N tyres specific to each of the classic models including the 944 as per the link, which I assume negates the only for 911's assumption?

... or which may confirm they may be as important on 944s as on 911s? []

What happens when you go to 17" wheels, stiffer ARB`s and springing, 968 castor mounts and modern rubber and tyre sidewall design?

I have no idea, go by the recommendations for the 968 if that's a more accurate comparison?

Porsche issued a note in 1993 :

What I meant was, when you change any one component from standard it negates the issue.........................doesnt it?

I just re-read this, the recommendations for the 944 and other older models as per the link was published in 2011 and includes modern rubber that is available now.
