Replying to: mikejg (Mar 12, 2007 4:41 am) The good news is that I have what appears to be very even tire wear. No difference in depth inside vs outside edges and both rears were the same. However, they are definitely more worn, with shallower tread than the fronts (est. 1/4" for rears, 3/8" for fronts), and my optimism that they would last another 5-7k+ miles may have been premature. When I get a chance in the next few days, I'll take the car to the local dealer - one of the service techs is a "track" guy - and see what he thinks. My guess is new tires will be needed at 15k+/- miles if I don't want to milk them past optimum performance. Obviously, how you drive your car makes a huge difference in tire life. My 12k+ miles have been pretty easy - no track time, a little "enthusiastic" driving, 60% highway miles on fair to good roads.

Replying to: fedlawman (Mar 13, 2007 3:23 pm) How about next week? I went to my Porsche dealer today to have the service manager look at the tires and he now claims the rears are ready to be replaced. Pretty odd that, at 10,711 miles (oil change/service) they "look great with lots of tread life left" and now at 12,415 miles they "should be replaced as soon as possible". Sounds fishy, but unfortunately, I think the current assessment may be correct. I'm going to try getting a qualified second opinion from someone that doesn't sell tires. After giving me the bad news on the rears, he did say the fronts "look good with lots of tread life left".  In any event, while I was waiting for them to put it up on the rack, I checked out two unsold 911 Turbos they have in stock. GT Silver and Slate Grey, both 6-speeds, with $131,000 to $133,000 stickers. We hit 75 degrees here today, so neither of them looked quite as good as my Cab S with the top down, but they are tempting. If anyone is looking to "trade up", check out Rockville Porsche. The salesman said they weren't discounting them as they were "extra" allocations from Porsche, but that's the same thing they said in August 2005 when I was Cab S shopping. A little sidebar with the Sales Manager reminding him that I bought from another dealer 50 miles away at a $10,000+ discount in September 2005 ought to loosen them up a bit.

I have been told by Tire Rack and my Porsche dealer that the OEM Pirelli P-Zero Rosso 19" 295/30 (N rated for Porsche) rear tires for my 911S Cab are completely out of stock and on back order. There is no word from Pirelli as to when they will be available. Replacing just the rear tires with Michelin or another brand is not recommended, unless you replace all four tires. Given that my fronts are only about 50% worn, I don't want to throw them out. Has anyone run into this issue and/or considered replacing the rears with 305/30's (standard on the Carerra S4)? Apparantly they are in stock, albeit in low supply.

Replying to: habitat1 (Mar 13, 2007 5:04 pm) With regard to the 997 Turbo, here are some anecdotal notes. Last week I was stopped at a highway gas station and a gent pulled up in a 993 Turbo. I chatted with him and he told me he had a 997 Turbo but didn't like it and dumped it. Recently I had my Boxster in for service and noticed two used 997 Turbos on the showroom floor. I am not suggesting anything other than my outlook is to be vigilant with all new models. You can take a considerable hit on them. It happened with the 996 Turbo and 996 GT3. |

Replying to: habitat1 (Mar 14, 2007 12:56 pm) Do what you want but I'd have no problem replacing front and rear with different brands. The logic is to keep symmetry on the axle. Plenty of people do what you are considering when switching brands. Front-to-rear is asymmetrical to begin with when you consider the front/rear differences in tire sizes, suspension settings and wheel angles.

Replying to: designman (Mar 14, 2007 4:22 pm) However, my dealer, before finding out the 295/30's were out of stock, quoted me a very good price on the Pirelli's ($360 vs. $440+ at Tire Rack). So I'm going to see what he comes back with on the 305/30's Pirelli's. I have to believe they will fit fine, since they are standard on the C4's and even on the C2's, there is a 5mm "spacer option to push the tires out further in the wheel well. I don't have that option, so I doubt I will have a rubbing problem just going to 10mm wider rear tires. It might actually make my speedometer more accurate, given that it reads 70 when I'm actually only going about 65. Any thoughts on the 305/30's idea? P.S. The Michilins are in the $480 range. A friend has the Michilins on his 911S Coupe, and I'll be darned if I can tell the difference. Supposedly lower road noise, but on a Cab, that's not a major factor.

Replying to: habitat1 (Mar 15, 2007 4:32 am) It seems preferences among owners are split between the Pirellis and Michelins. I've heard that the Michelins last longer. Seems those PZeros melt away quickly in comparison. BTW, I also heard that TireRack won't be getting Pirellis for the 997 or perhaps all P-cars because Porsche allegedly has an exclusive arrangement with Pirelli. I have no idea whether this is rumor or fact. I read it in the blogs. Seems odd.
