Time for tires! 05G coupe with stock 19s

[joe603]

I'm at about 16,500 mi. and the stock tires are almost gone. I'll be doing this in the spring. Just a few questions on tire options...

The OEM sizes are:

front 225/40-19rear 245/40-19

TireRack.com has the following optional sizes:

front 245/35-19rear 275/35-19

Is this the widest tire that will safely fit on the rear? I'd like to know what else would fit on the rim.

rear 275/30-19

I'm not a tire expert, so I'm not sure what the optional sizes would look like. I would like a wider rear tire, if possible. Can someone explain what the differences are between the two sets of tires? Thanks!!

front size: 245/35ZR 19rear size: 275/35ZR19(tire rack prices)

Goodyear Eagle F1 GS-D3traction:front 280 AA A ($299)rear 280 AA A ($279)

Michelin Pilot Sport A/Straction:front 400 AA A ($328)rear 400 AA A ($331)

Yokohama ADVAN sporttraction:front 180 AA A ($306)rear 180 AA A ($335)

WOW, you burnt those up quick. I have an '05 as well and 24,900 on the odometer and I am still on my original set of front tires with a ways to go until replacing.

The back both got nails and I had the tire maintenance thing so those were replaced free but the fronts are original.

If you get something different than the Bridgestones let me know how it drives. I might get another brand when it is time to replace as well.

Ya, I'm not sure why they wore out so quickly...I haven't been to a track, and I don't do burnouts. Crappy tires.

Ok, I'm doing some research...I wanted to post this on the G35 board as well...

The OEM size for the G35 with 19's is

F 225/40R 245/40

If you multiply 225 * .4 you get 90...which is the side-wall height, correct?

Now with another tire, say 255/35; multiply and you get 89.25, almost equal to the OEM side-wall height, but 30mm wider...Correct?

So, this new tire should stick out of the rim more than the OEM tire, but be almost identical to the side-wall height, thus not affecting the VDC???

Can the rim handle a tire that is 30mm wider?
