Since the 997 GT3s have 19x12 rears, what's your thoughts on running 315/25/19? The 997TTs have 19x11 and they can run 305/30/19 (same as stock 3s), so if 305s can fit on 11" widths, I don't see why we can't run 315s on 12". BTW, they have the 315s in PS2s.

 

it's not the width but the rolling diameter. the stock PS2 305/30-19's overall diameter is 26.3''. the PS2 315/25-19's overall diameter is 25.2''.

 

How about 315/30/19?...rolling dia is 26.4". Basically, I want the tires to be wider. So what other sizes are others running (F & R)? Thanks! Anyone running wider fronts to match the wider rears?

 

is that a new size?

 

Hmm...yep, 315/30/19 is not available. Only 315/25/19.

 

Why do you want wider rears?

 

Agreed. There have been posts here before on OD differences. The 997 is not the 996 - there has to be a taller back tire on the new ones.

 

315/30 19 isn't a size anybody makes a tire in. At least not a tire we carry....
