Thanks for the info !

 

Hey man. I recently switched to 305 from 295, from Michelin PS2 to Nitto Invo. First thing, these tires have SO MUCH more grip, and SO MUCH more predictable at the threshhold, I can push them further with MUCH more confidence. I don't track the car with these tires, but I have done a few VERY spirited drives with them, off-ramps, off-camber esses.

Anyway, to answer your original question, I definitely think the extra width has helped grip, especially around turns. Biggest problem now is, I feel that the notorious porsche understeer has been exxagerated with the extra width in the rear. I would recommend also going to a 245 tire in the front to balance the staggered fitment and neutralize some of the extra understeer. Hope this helps!

 

Thanks for the great info. Yes that famous understeer..... I also sometimes feel the car wobelling alot when taking corners at high speeds.

 

Who sells those nitto invo`s - i looked at tirerack but got nothing in search results?

I am shopping for new tires for NB Carrera Sport Wheels: front 235/35/19 and rear 305/30/19. My original thought was to go with the OEM Michelin PS2. But, the price is so much higher (sometime almost double) than other brands that I am reconsidering.

Has anyone tried other tires for the above size? Why such a big price difference? Do PS2 last longer?

Thanks in advance for advice.

 

PS2 are the best. I would not compromise for my primary tires but to burn those PS2 down on auto-x is outright stupid. You can smell your money burning after each run.

 

A different perspective is that for higher performance driving on track or auto-x, the better tire will perform better. And for tamer street driving, perhaps it's not worth using the most expensive tires?

 

I have those tire sizes on my C4. I switched from the OEM PS2's to the Bridgestone RE50A's, and absolutely love them. Amazing grip and I think I saved over $600 vs. the Michelin's. Still more than the Nitto's, but I wanted to stay within Porsche spec, just in case.

 

How's the noise level on those things? I think the PS2's are great, but I keep thinking about trying something else.

 

'Better' on street is not same as better on track. Best bang per buck tire for auto-x as I understand from Nitto line is Nitto NT-01 and it is not something I would put on permanently for street driving.

 

An all season radial has to be formulated w/ a compound that does not require high temps for best performance and has a tread design that will shed water effectively to delay aquaplaning. High performance tires suitable for track use typically have compounds that adhere better w/ increasing temp and may have little or no tread (slicks). Wet pavement performance is often not a strong suit for our Porsche specific tires.

 

Hi Guys (and Girls)

I just bought a 911S Cab and need new tires - got the original Michelin Pilot Sports that are done.

I am thinking about following the recommendation of this thread of going with 305/30s and found Bridgestone Potenza RE-11 "Extreme Performane Tires (http://www.tirerack.com/tires/tires....omCompare1=yes) with pretty good reviews at great prices (Front $184/Rear $320).
They are probably pretty bad in snow, cold weather and rain, but living in Vegas eliminates that problem.

Do you guys have any thoughts/experience with those tires?

Tks a lot
