Default Will my wheels fit my Cayman 2007

Hello, I bought a set of used oem wheels, front 19x8 and rear 19x11.
I am planning on buying 305-30 ZR19 rear and 265-30 ZR19 front.
I have 7mm spacer in front and 25mm in back
Can anyone tell me if those tires will fit my 2007 Cayman???
Thanks in advance

What's the offset on the wheels? A 265 tire on 8" is not ideal.

Preferred tire size in the front is either 235 or 245. I don't think 265 will work unless you have a fender flares or wide-body.

Thanks for you replies, I am not sure what the offset measurement is, I will measure it and post it tonights?
I made a mistake, the width of the front will be 245.
I will also verify if I can reduce the width of the rear based on my wheels...

For the rear wheel, If my measurements are right, the offset is 2.75 inches.
If we take into account the 1 inch spacer then the actual offset would be 1.75 Inch???
For the front, the offset is 1.75 I have a .275 spacer in front if need be.

Thanks

lobster claws from the 997 Carrera. I use them for tracking with my Turbo. Doubt they would fit on my '09 Cayman S.

Front is not problem, 8 works. Wider as well.
Rear you may run in to strut or fender.

The offset should be marked by the valve stem. You should see something like 11_67 or 11_51. No need to measure backspacing to figure it out.

11 57

The 8" front will be okay with a 7mm spacer.

Are you sure it reads "11 57" and not "11 51"? Factory widebody 997 cars came with a 51 offset.

If it indeed reads 51 you're looking for a 13-14 mm rear spacer so the effective offset is around 38 or 37. You could probably run a 15 mm spacer but will likely rub on the fender under load running a 305 tire (depending on tire brand/model). Much better off running a 295/30 tire.

Sorry, it's 11-67

You're gonna need a ~30mm spacer in the rear to clear the struts on the inside. Test fit with 25 mm and see if the inside of the wheel hits the strut. Temporarily stack the 25 mm and 7 mm and confirm if it clears.
