Tyres. approved by Porsche??
I was talking with someone today about tyres for my 944, and this guy, also a 944 owner advised me to get tyres with letter codes N0, or N1 or N2 or N3.
He said that every company makes some model tyres as per Porsches' specification. Can anyone outhere shed more light on this subject? Thanks

As long as you get a name brand tire with the appropriate speed rating, you're fine. I wouldn't recommend anything less than an "H" rated tire though.

The sidewall construction of n-rated tires is slightly different than the regular stuff each manufacturer puts out. These cars just feel more stable at high speed with n-rated tires, but you shouldn't mix/match the n-ratings. n0 was the first rating, very good in the dry. n1 tires got better tread wear, n2 was improved for wet weather, and n3 I'm sure was improved some more but I forget how. My n0 tires were scary in the rain and lasted like 8k miles. I haven't bought n-rated tires since.

PorscheG96, thanks for shedding some light on this subject, and I sure can understand why you no longer bought N rated tyres. I guess Pirelli P7000 with a R speed rating will do me just fine.
Thanks again

 I've got a set of H rated Bridgestone Potenza RE 950s on my 924S right now and they've been great for all-season driving. True the tires aren't rated for above 130 mph (H=130, V=149) but I'm never going to be going any faster than 85 or so if I'm in Michigan. Would a V-rated tire be better in the summer? Sure. But I doubt that there are very many V-rated tires that could have handled the snow we got in Pittsburgh last week. It's a trade-off. An H rated tire will perform just fine for on-road driving. Unless you're very agressive a V rated tire isn't a necessity. Aaron

Well, I tyre that holds up well in a hot and humid climate. I tyre that will not get a flat spot if it sits for a couple of weeks at a time.
Pirelli P7000 are available at a good price from the main tyre dealer, and they were manufatured last year. I may be getting a set of these, as soon as I get the water pump, timing belts done.

Also, when you have a car that the manufacture says not to go under a certain speed rating, you will lose some of the handling characterists and you will increase braking distance. The speed rating isn't just about how fast you can go without the tire exploding. Thats a typical misconception. I know exactly what a Porsche feels like with the incorrect speed rated tires. I unfortantly don't practice what I preach. I don't have the money for tires and I don't plan on keeping the car long so I don't want to waste the money. Again, if money is an issue, then you may as well go with an H-rated tire. But if you have the extra doe I wouldn't cut corners.  Coupe, what size are you looking for? |

Honestly, the H rated RE950s feel a lot better than the tires that were on the car. I understand that the "speed rating" is also related to sidewall strength and not just to heat capabilities. I also realise that a lower-rated tire will flex more under breaking and cornering, and that handling will be sub-optimal. Still, the car is leaps and bounds above the capabilities of my last car, and I doubt that I'll ever excede the capabilities of the tires I have on the car. Aaron
