Tyre Advice

Hi All, hoping someone can advise.

I am the owner of a 2004 4200 GT. Car has Pirelli P Zero Assimetric on the rear that are ready for changing.

I really want to stick with Pirelli as recommended fit by maserati.

Question is this: Will it make any difference fitting P zero Rosso's as opposed to the Assimetric tyre? Has anyone any experience of running the non-assimetric pirelli tyre?

Only ask as I can get a good deal on the Rosso's but not the Assimetrics?

thanks

I run the Rosso's in 19 inch for the GS.
I find with the way I drive I go through 2 sets of rears for each set of fronts, so don't worry too much about the choice as you'll be replacing it soon enough.
I can vouch that new rubber, whatever the type sticks much better than older harder tyres.
I used to get chirping and squirming under hard acceleration with the old Goodyear F1's my car came with. New tyres just gripped and slingshot the car forward.
Only those who've run the assimetric, vs normal will be able to answer your question in terms of handling advantages.
I think you'd have to be going pretty hard round corners to gain the advantage.

Don't know anything about either but I'd read up on different manufacturers tyres, Italian car manufacturer recommends Italian tyre manufacturers products sounds more like a cosy arrangement than anything to do with the actual performance of the tyres

I hate Pirellis. They only work if it's 70deg or above and dry. Otherwise, they are plain useless, as the F1 boys are finding out this year. My Ghibli has them on 21s and I was disappointed recently to learn that they still had 4mm of tread on the rears. I really wanted an excuse to change them.

Try Goodyear, Conti or Vredestein, all are better in our weather.

I too am a serial Pirelli hater, they have a sweet spot and outside of that they just don't work, IMO.

I'm a big fan of Goodyear Eagle F1s, the original ones were great if a tad noisy but the new AS2 are so much better, I have them on the Spyder and my Alfa GT

The main benefits of running the asymmetric tyre is improved outer edge grip for cornering, better water displacement in wet conditions and in theory should last a little longer than the normal pattern tyre. I'd recommend the asymmetric, in my opinion worth the extra especially if you use the car in wet weather.
I run Goodyear Eagle F1 asymmetric tyres and for me they are the best all round tyre I've had. Very good in the wet and give excellent feedback.

Hope this helps.

I changed my rears after the Italy trip. The Pirelli's had split all the way around the inner shoulder which was pretty scary to discover. The split couldn't be seen until the pressure had been let out.

I have gone for Michelin pilot super sport, seem pretty good to me - no splits so far...

Running vredestein ultrac vortis on the GS and very impressed so far. Giugiaro designed too, just like the car.

Have used Pirelli PZero Assymet, PZero Rosso and Mich Pilot SSports, all are excellent tyres with track use and fast road in all weathers, including snow (they are all **** on Masers in snow)..!! I tried Falcons and found them lacking when really needed..!!
As they are the only thing keeping the beast on the road, I don't skimp on my tyres..!!

I have not tried the pirellis on this car, but never liked them in the past. Have tried vredesteins, and Falkens, and now on Goodyear Eagle F1's. The Falkens have soft sidewalls which makes the car ride potholes and drains better but are poorer grip than all the others on track or serious driving, although they are very predictable and this can be reassuring. Eagles are harder and better grip than the Falkens or Vred's All of these three in my book noisy on the road. Toyo are notoriously soft tyres so good grip in dry and in serious driving but dont last long, not really rated for wet or snow, used to run Toyo's on my two TVR's and with them being so light it was a perfect fit. Falkens were extremely good in the wet by the way, i reckon better than the Vred's or Eagle, could be a tread pattern thing and they all change so may be nothing. Tyres are a very personal thing, and depends to some extent on your driving style, and whether you give you car the herbs often, and indeed whether road noise and comfort figure in your thinking? also if you plan to drive in the winter then all season or winter tyres are a good plan?

Davy, to get the winters for the AC/4200 wheels, one set has to be 5mm narrower (sure it was the fronts) but inperceptible difference, they are then a standard BMW fit and readily available... Transform the winter driving experience completely.
