I have a 2004 G35 Coupe. I am currently running a set of summer tires that I got with the rims from a fellow forum member with no problems at all. I need to replace them (they are shot) with all seasons and I have decided on the Conti DWS.

Since this is my first G, I wanted to be sure I had correct sizes so I did have any issues. I tried to get close to the diameters of the current setup....The sizes look good to me, will they work OK?

I currently have:

Front
Michelin Pilot PS2

245/35ZR19
Load Index 93
Speed Rating “(Y)” = 186+mph (300kph) (93Y) XL
Rim Width 8-9.5"
Sect Width 9.8"
Tread Width NA
Overall Dia 25.8"
Revs Per Mile 807

Rear
265/35ZR19
Load Index 94 = 1477 lbs per tire
Speed Rating “(Y)” = 186+mph (300kph) (93Y) XL
Rim Width 9-10.5"
Sect Width 10.7"
Tread Width 9.7
Overall Dia 26.3"
Revs Per Mile 790

And I am looking to use these sizes:

Speed Rating “Y” = 186mph (300kph) 96Y XL
