Seeking Origin/Manufacturer of 19” Wheels (see pictures)

Does anyone have any background on these wheels?  I can't find on the web. Rather large at 19" and have Allen keyed lug bolts that I want to replace and can't find either.  With so little sidewall I'd like to locate a couple replacements.  Any information greatly appreciated.

Rear tires wear

I have a 1999 Porsche Carrera cabriolet and my question is that I cannot put more then 10,000 KM on a set of rear tires. Is there a problem with my car or my driving (I do not track or race with the car). I have tried Bridgestone, Yokohama (265/35/18R) without any success I still have to change the tires around 8,000 or 9,000 KM which is not a lot. I try to purchase tires with the hardest gums but no positive results. Does somebody have the same problem, if there is a problem or is this a normal situation? There is no problem with the front tires, normal wear and tear.

Temporary spare tire replacement

I need to replace my 105/95 R17 90M temporary spare tire and am having a hard time finding an exact match. Does anyone know of other sizes that I can use on that rim and still fit in the trunk. I solved my own problem by researching and comparing dimensions. The Continental CST17 in 125/80 R 17 99M fits perfectly. The cover is snug.

Any aluminum-based anti-seize lubricant can be used on wheel bolts?

Good Day Comrades,

The owner's manual in my 2003 911 (996) asks for a light coat of Optimoly TA (aluminum paste) to be applied to the wheel bolts before fitting.

The Optimoly TA / Castrol Optimol Paste TA is quite a difficult find (no Porsche or BMW dealer had them), and quite pricey when quoted ($80 for a 4oz tube or so).

Is Permatex Aluminum Anti-Seize Lubricant #80078, Wurth AL1100 Aluminum Paste Anti-Seize, or Loctite Aluminum Anti-Seize Compound LB8008 (Part#5114) an appropriate substitute?

Why is my rear tire smaller Diameter than my Front ( ? )

Bill, John Ellis from GGR San Carlos checking in again.  I will send some images to the address to better demonstrate my challenge/ question.  Here is what's up.  I used to have a 2001 Carrera with 19" Lowenhart 3 piece wheels, Rear tire size is 285-30-19 ( 25.7" diameter ).  I have no clue what the offset is as I can't find much info on these nice wheels as Lowenhart is out of business. Regardless, I really like the appearence, fit and performance of these wheels ( my tires are the Conti DWS fitment ). A liitte inside rub on the fronts, but nothing extreme or damaging.

Wheel compatability

Looking to upgrade 18 inch wheels on 2002 c2 to 2004 gt3 rims. Is this a good idea?

Rear vs Front Tire Size

How big can I go on my rear tires without causing traction problems on the front. Today I have 275 / 35 / ZR18 on back Michelin Pilot Super Sports and 225/40/ZR18 Falken on front. Bummed the new rear tires wore out fast 18 months compared to front used over 3 years. I'm told that big on back can create front oversteer. So what should I do to optimize balance, treadwear and traction yet still have fun taking fast hard turns freeway or racetrack?
