19" Tire Size help
Alright looking for a little info as im entirely new to the porsche game and from other threads i have picked up that you can mess up the Differential with to much of a difference in overall diameter from front to rear wheels...
I recently purchases a set of wheels
19x8.5 + 40
19x12 + 65
what size of tires would you guys recommend..
Thanks in advance..
Cheers

I'm assuming you have a Carrera 4 or 4S since you're worried about AWD tire size matching. If your car is not all wheel drive, you have nothing to worry about.
For tire sizes, you have several options.
I have 19x9.5 and 19x12s on my car and I run 235/35s and 295/30s.
235/35 and 315/25 is also an option.
As is 245/35 and 295/30. Howeve, I would not run this combo on your wheels because the front tires will have a slightly "ballooned" sidewall, while the rears will have a slight stretch to them.

Depends on your road conditions and if you're riding stock or modified suspension. With 8.5 fronts, stock suspension, good to moderate roads, IMO, 245/35/19 fronts, 305/30/19 rears on the 19 X 12's. YMMV. GL.

I also have 19s on my C4. The fronts are 235x35x19s and the rears are 285x30x19. I tried to get 305s on the rear but they just wouldn't fit. Now that I have the car lowered with coilovers, I might try again or maybe go to 18s with a wider rear tire

You don't want to put 275's on the back of a turbo. Check down on the 996 Turbo forum and see what some of those guys are running. I looked into 19's a while back and there were just too many variables to contend with. Also, if your roads are bad, 19's aren't going to improve your situation.
I'm going to 996 GT2 sizing when it's time for new tires. Much wider and slightly taller so it should give me the look I want. The taller sidewal should help a bit with the potholes.
Good luck.

The viscous coupling on these cars is not fragile, it can handle a lot of abuse. A few % difference in tire diamter won't hurt anything.

My issue is that BMW spec'd a 235/45-19 for the front of my wife's x3. Tire choices in that size are shyte. The oem difference front to rear is .3" (1.15%). I want to step up to a 245/45 front (2.3% delta). Think it will work? Appreciate your opinions.
