larger tires on stock rims
Hey guys, my 05 is due for new rubber. I'd like to put on wider tires on my stock 19s. Has anyone done this before? Any pics of the results?
The stock sizes are:
225/40-19 front
245/40-19 rear
I'd like to put on
245/35-19 front
275/35-19 rear
What do you guys think? I don't want to hurt performance, but I don't like the skinny look of the stock setup...

I have stock 18's (2004)
245-40-18 front
255-45-18 rear
BFGOODRICH KDW2's
With 255 the rear starts to buldge on the bottom. I would still go for 255 for the staggered setup but maybe try going a little lower profile. Maybe try 245-35 and 255-40. Ask your local tire tech and see what he says.
BTW with my new setup the car handles WAY better. KDW2's have the best treadware/performance/price out of the other tires in my range.

Thanks for all the good replies! I've been on the fence with this one for a while now. I asked a tire tech the largest tire that could fit on the rear 8.5" rim...according to him, 275/35 would work. I'm just not sure if it's a good idea. (don't want to hurt handling, I want more grip!)
This is a cool website that allows you to play around with different sizes. Thought I'd share to the group....

These Coupes already have issues with the rear tires wearing prematurely on the middle treads with the stock tires. I would be careful going any wider as you will be changing the footprint of the tread and possibly start making it concave causing the middle tread wear. Don't necessarily believe the specs for your rim width. It's always safer to go with a rim width at the top of the recommended sizes. Too wide a tire on too narrow a rim will cause the tread to bulge outwards.

I just installed 245/35/19 Front and 255/40/19 rear. It looks great, and I can launch better with less slippage. Anything wider in the rear is not a good idea.
This tire size calculator rules all. Check it out...you'll see that 255/40/19 rear is the closest to stock height that you can get.

And if you want the best possible prices for Toyo tires, I'd recommend TireDeals4Less (site sponsor). I couldn't believe how inexpensive they were compared to other vendors.
