Best looking wheels on a 996 Turbo
#991
Wouldn't that make the rear taller than the front? I thought that was a no-no...
#992
SO many variables and I'm confused. Maybe a better, more straight-forward question for all of you more in the know than me...
What 19" tire and rim combo would you suggest?
19x8.5 & 19x11?
Tire sizes?
Thanks for the help here.

Thanks...but doesn't that make the front shorter than the rear? I thought that was a no-no with AWD?

Very few people have an understanding of how the rather simple 996TT AWD system works. The ONLY way the system can transfer even an ounce of torque to the front wheels is if the rear wheels are rotating faster than the fronts. If it's the other way around then the front wheels are simply providing driveline drag into the gearbox through the viscous coupler...

This looks like a good match.

The front tires must be taller (less revs per mile) than the rears, or the AWD system can't transfer torque from the rear wheels to the fronts. Correct?

Using the same logic, obviously if your fronts wheels were a little smaller than the rears, then drive line drag would increase as the speed of the vehicle increased. Obviously is is the exact opposite of what you want.

Thanks pwdrhound, totally makes sense.
So, in the end, it's irrelevant when someone quotes the ''it's within 3% tolerance'' and everything's going to be great.
If the front tires *are* shorter, the AWD system isn't going to work as designed and the car will basically act as a RWD car. And there's the potential that the drag created by the shorter front tires may cause issues/damage to the viscous coupling. But best case, the AWD isn't going to work properly.

Well that sucks. There is no PSS setup that will work where the fronts are taller than the rear's unless you do the 225/40/19 and 295/30/19's and then it's 797/799.
Would you guys prefer less front end grip (225 vs 245) and AWD, or RWD with more front end grip (245)?
Which is the lesser of two evils?

Well, this is interesting...I went with the following Yokohama AD08R tire combo on my current 18" setup. I figured I'd be completely fine going with stock tire sizes of 225/40/18 and 295/30/18.
Tire Rack however, shows my front and rears to be the exact same height...with identical rev's per mile. Any issues/problems with this??

Stock vs. 19" OD:
225/40/18 25.1
295/30/18 25.0
225/35/19 25.2
235/35/19 25.5
245/35/19 25.8*
295/30/19 26.0*
305/30/19 26.2
305/25/19 25.0 NLA (No longer available)
315/25/19 25.2
Many will chose to go with Blue option most of the time since they are electing to enter into a 8.5" front and the 225/35/19 would be a bit of a stretch even-though it would be a good match with the 315/25/19.
Most also are veering away from the 315/25/19 since there is a lack of choices available at this time, years ago Michelin PS2, Continental, Toyo T1R, Nitto Invo and Falken 452 were all pretty available but we are down to Nitto Invo and who knows how long that would last. The 305/25/19 was a great fit but those have not been manufactured for a very long time and even if you find old stock they are sure to be out of date.
IMO, the 245/35/19 and the 295/30/19 is the optimum sizing for the C4, C4S and Turbo models that run 19x8.5 and 19x11 set-ups.
But do your own homework to satisfy your needs...
