SPANKY LS1

I ordered a wheel/tire setup for my 2006 C6, sizes are below.

F: 19x10 275/30/19 (25.6" dia = 3.3" sidewall)
R: 20x11 325/25/20 (26.4" dia = 3.2" sidewall)

Now, everyone knows how crappy the roads are around here (suburbs of Chicago). The factory runflats (245/40/18s w/ 3.85" sidewall and 285/35/19s w/ 3.95" sidewall) have a reputation for riding terribly and they do not disappoint, the ride is atrocious lol. The car is a "fun only" car, only driven for cruising, shows, etc, not a DD by any means, so the ride does not really concern me too much, but I really really really really don't want to damage a $$$ wheel.

How "hard" is it to drive around on tires with sidewalls this thin? Other than avoiding potholes at any cost and crawling over RR tracks, what other precautions should be taken?

FWIW, the tires are "XL", which, if I understand correctly, stands for Extra Load capacity. The load rating on the fronts is 1565 lbs each, and 1819 lbs each for the rears, compared to 1235 lbs and 1323 lbs for the stock runflats. Will this extra load capacity help in making the wheels "safer"?

Thanks, Shawn

I ordered the same size back wheel...however, the wheel guys are recommending i go with a 305 and are saying the 325s would be a very tight squeeze and would rub with the inside walls

as for the 19/20" setup...i loved it on my c5...love it on the viper....no issues except the ride got a lot better for handling and comfort in the c5 car also looks a million times better

I ordered the CCWs, the offset and BS is perfect for the 325s, he even suggested to only run the PS2s, that some of the others might not fit, so it must be a tight fit.

Here are some CCW 505As, 20x11 with 325/25/20s. As you can see, the rears fit just perfect, not much room for error.

Anyone else?

With a 275/30/20 in the front
and a 335/30/20 in the rear

On my previous car, I had 275/30's on the rears. After replacing the tires a few times, I finally sold them. I drive around new york city, so if the roads in chicago are anything like these, I don't know how well that size tire, or the rim, will hold up. Somewhere like florida, where the roads are smooth and straight, another story. Good luck though

hey, wondering why you didnt go with a 25 series tire in the rear to keep the OD the same or close to stock. the rear of your car looks a little too up in the air and i think it might be because of the 1 inch extra diameter

greentank

I dunno...but I like that look.

In those pics i have the suspension cranked all the way up for shipping puropses


I did not want to go with the 25 profile just too small

Also John at ccw nailed the offset so the setup fits perfect

427Z

cool, so i take it you're going to be lowering it back down

burtonbl103

Yes
Once it is back From Lingenfelter
I am going to return it to stock height and have it aligned

What size tires do you run? Got any more pics?

Thanks, Shawn

Have you driven the car any with the new wheels and tires? Won't that cause problems with the ABS/TC system?

Aren't the VSS expecting the front and rear wheels to be turning at certain speed "ratios" in relation to one another (not so much the same, just at the same percentage ratio, front to rear).

For example, the stock tires are 25.7" (F) and 26.9" (R) diameter. The fronts rotate 808 revolutions per mile, the rears rotate 775 revolutions per mile. The rears rotate at a 96% rate when compared to the fronts.

Your new tires are 25.6" (F) and 28" (R) diameters. The fronts rotate 814 revolutions per mile, the rears rotate 744 revolutions per mile. The rears rotate at a 91% rate when compared to the fronts.

For every mile that you drive and the VSS relies on data to determine weather Active Handling/Traction Control/ABS is necessary at any given time, your tires are rotating much differently than the ECM thinks is "normal". Is there enough "flexibility" so that the ECM figures out what is going on without causing problems?

Doing the Z06 rear fender conv. on my C6, would you go 20x12, 12.5, or 13" for the rears?

How heavy are these combos. Lokks good but I would hate to add anything that actually hurts performance.
