Filling the wheel well requires a drop it would seem. I was looking into 18,19,20+ inch wheels. Without balling up your speedo and computer inputs it looks like the same OD is the way to go. I did find a Bridgestone in a 255-45-18. Slightly larger OD (looks better) slightly wider (good thing)...Not off far enough in diameter to cause problems and hose up the already stiff ride. It looks like the wider the tire, the lower the profile. The 265-275-30-20 would ride like an old truck, there is no sidewall !
I was looking at a set of HRE or Asanti wheels. 19x8.5 and 19x9.5. Wearing 245/40/19 and 275/35/19 SP2. Just waiting for WAF.
I am also hoping someone comes out with a suspension kit that lowers the car just a bit (1/2-3/4 in front and 1-1.5 in back). I have seen (sat in) Mallett's CTS-V with the 19s and his suspension (which lowers it 1/2" and 1.25") and it looks awesome.
Using 275/40 - 18 in the rear gives you a tire that is nearly an inch wider but has the same sidewall and rpm's per mile. So the ride won't be harsher and the speedometer will read the same. I would like to find some wheels that will fit the car and those tires. Any suggestions would be appreciated.
If you get rid of the run flats, you have the spare, jack & stuff problem. What are you going to do about that? The incert for the spare in the trunk will not accept a tire either. I would like to go to a different tire but there are a lot of obsticles to overcome!

I've been driving for over 20 years and I put between 40,000 and 60,000 miles annually on 3 cars. To date I have NEVER had a flat while driving down the road. I've had slow leaks from picking up a nail or screw in the tread, but never an all out flat while driving down the road. Not saying you shouldn't worry about it, just saying it's never happened to me.
Don't we have "Roadside Assistance" with our year of OnStar anyway. Why have a spare? I've driven my last 4 vehicles over 170k miles each and the only flat I ever got was from a big piece of ice I hit on our wonderful Michigan highways and it took out the tire and the rim and a lug so a spare wouldn't have helped anyway (but roadside assistance did).
The plastic insert in the trunk will come out (did it). The hardest part would be finding a spare. I feel the same as "CVP33", many cars, no flats. I figure with onstar and a cell phone I can take care of that problem. Regardless, I want some type of chrome or forged wheel and a bigger tire for the back. Wish I could find out who makes the 18" 1-peice forged wheel for Mallet.
