Well guys apparently nobody in the northern side of this continent has NITTO INVO tires 315/25/R19. Everybody is out of stock and the backorder could be for 2 months. If anybody knows well to find it, please let me know.

 

Switch to Toyo's or make the switch to the 245/35/19 and 305/30/19 combo

I made the switch from 315 to 305, I prefer the 305, the added sidewall makes a huge difference in the 30.

Best of luck!

 

Thanks for the info...my biggest problem is that my wheels are 19X12 and a 305 will be too stretched...if I go with 325/30 it will rub with the inner plastic. The other thing is that I only need the rear ones because the front tires are barely new.... if I have not choice I think I may had to buy all four from other brand. This will be for the X50 which is stock in all aspects.

 

They won't be stretched. Porsche OEM wheels and tires on the 997.1 GT3 are 19x12 with N spec 305/30/19 tires. If the factory does it so can you......
The 305/30/19s won't match up with your fronts if you're AWD however....

 

I have 235/35/19 in the fronts and I'm running awd would the 305 works?

 

It would not...
