1999 996 with 295/30/18

[JoeA]

Has anyone put this size 295/30/18 on their 1999 C2?

Do they look right, the TSB says they are approced but holy cow, they look a little wide.

Note that it also says on (page 3) that the approved wheel offset is 63 mm (not 65 mm) AND "Footnote 3. The wing seam and if necessary the rear spoiler must be reworked on vehicles up to and including M.Y. 2001. See note on page 8."

If i have wheels with an offset of 65 is that going to be an issue?

I do not have a spoiler, wing seam?

Most likely 65 mm will be a problem or they would have spec'ed it differently.

In this case their "rear spoiler" means "rear bumper" to you and me. What they say is that it will need to be reworked or rubbing/tire damage may result. Seems like a lot of trouble for 10 mm (less than 1/2 inch) more tire tread width. A 285 is 11.6 inches wide - so a 295 is 12.0 inches wide.

Unless you have the 63ET wheels why would you want to run the 295 rubber? For the 65ET run the 285 or 265 rubber.

they came on the Wheel, I wonder if I could get the rubber swapped out to the smaller size and be ok.

Isn't the lower ET mean that the wheel will stick out more and be more likely to rub? So a 65ET is the better bet here with 295's as opposed to the 63? Assuming the rub concern is on the inside of the wheel and not the outside....

I am having my wheel flanges machined down 5-7mm as we speak for $35 a wheel. So if you are worried about the outside rubbing, that could be your low cost option to get them to fit. If it's the inside, buy a small spacer like the one Porsche puts on certain models.

265's not a problem on the turbo look2 rim?

[PorschePRH]

I have 265's on my 10 inch rim and it looks small on the rim, but in an ok way. If it was an 11 inch rim, I can not believe that it would work...

[LVDell]

Won't fit on an 11" rim. Max size is a 10.5" rim for that 265.

LVDELL,

Would 285's solve my problem?

Or would i be in the same shape regardless?

[LVDell]

285's on 11" or 10"???

[LVDell]

Forgot to mention that I run 285-30 on my 10" rims......both my Sport Designs and my Carrera Lightweights. The GT3 has the 11" rim and runs the 295 rubber (just uses a 63ET versus the 65ET).

285's on the same Turbo look 2 rear rim 11".

[LVDell]

Ok, now I am confused. The T2 rims are 10" not 11". What is you question?

Lesson learned, stuck them on, sticks out an inch, looks rediculous. Anyone need a brand new set of Turbo 2's?

I will be looking to fix this, this week. Loren was right at the tire it is 12inch wide apply that to that on the car, it will function fine, no clearance issues at all, its the overall look that lets you down.

Any pics?
