Just as an FYI i'll let the group know that yes, you can use "grossly swollen" tires under a near RS ride height WB.

I recently acquired a set of 996 TT wheels (in SY!) shod with NT01s (Thanks Chris W !).
Rear tires = 315 - 30 X 18
Front tires = 245 - 40 X 18

I was primarily interested in the wheels, but could not resist seeing if the tires would fit without rubber-to-sheetmetal contact.

I did some testing on Saturday and an AX on Sunday with no fitment issues.
I'm not saying these sizes of tires is a good idea................
just letting you know what's possible.

My car has -2 degrees camber front and rear.
Ride height = RS +10mm
Fenders are NOT rolled

Rear tires work with no issues, i think i'd feel a bit more comfortable if fronts were 245 - 35 instead of 245 - 40.

Cheers

No comments about the lovely color combo.................. please.
Even for track wheels, SY and Iris Blue is barely tolerable.

 

I actually like it

 

I'm running 996TT Hollows with the 295 rears on my C4S . Although the look is much better IMHO, I don't feel the ride or handling are better.

Any wider and you'll need to tub the rear!

+1... I dont know why, but I like it

315 on a wide body is not surprising, 285-295 fits my narrow body easy.

 

Just throw some Sonoco graphics on there and you are good to go. I nice alternative to all of the "Gulf" cars running around....

 

Make sure the rolling diameters in the front and rear are within 4%, otherwise your AWD system won't like it.

 

What AWD system?


I believe this car has been transformed into a c"2"s.

 

You are correct sir. cgfen is 2wd now.



Almost Craig....just 900hp shy...

 

I'm running 295/235 with no issues.
Good to know I can throw some 305's back there!

What's up with the painter tape? Cone marks come off easy, or you just don't hit'em!

 

I'm running 205's and 255's -- no rubbing at all.

 

Wow....now that has got to be one planted car!
...pssst, btw, don't tell anyone, but I think it looks kinda cool for a track car. Dunno why, but the yellow works

What tire are you running 315? I'd like to look up what the tread / section widths are. I've been thinking of running Kumho's 305 or Hoosier's 315 next season. Hooser 315 A6 have a section width of 12.5" and Kumho V710 have a section width of 11.8" on their 305s... now when you look at the Michellin PSC for a 295 your at 12.1"

I think remember reading WB folks running 295s for the pilot sport cups which would hypothetically mean I could run the 315 A6 and have no issues. Plus I'm betting whatever 315 you have is probably wider than the A6 315

The OP is running Nitto NT01. Louis - What tires are you using?
