Short answer is nothing. Changing brands is your best bet.

We didn't even have an emergency tire in that area, so sorry you had to leave your baby behind...

Some have put in spare tire kits and some have just thrown a spare in the back but that takes up to much room...

Guess your can of sealant didn't work either....

Hope everything turns out ok....

I converted to 20" front and rear which are easier to fine. Plus I have to spare tire & rim combos at home. I take one on long trips.

Thanks for all the help

I'd like to know what kind of wheel tire combo you went with. If you have pictures that would be great also.
Thanks

I switched to Toyos - they hold the road MUCH better and are available.

There is no cure and only one real solution. Call the BBB at 1-800-955-5100 which is step 3 of the dispute resolution. This can also easily be interpretated as a real safety issue. The rims were specified by GM and there NO alternative applications recommended. There are only two manufactures that offer the fronts and rears as matching sets, also recommended. They are Goodyear and Firestone. Goodyear has no production schedule for the rear tires at all. They have a tentative production date for the front of 4/21 but did not refer to what year. Firestone has fronts but no plans for rears in the near future. This is NOT an acceptable situation and General Motors attitude that this situation is the owners problem is unacceptable. The Better Business Bureau complaint resolutions service agreed and processed my complaint. No spare, run flats not available for the front and no rim with the specified offsets make this tire requirement unique. Protest and spread the word

What size tire and aspect ratio did you use for the Front?

gsp · 03-10-2008, 12:31 PM

all you have to do is run a 255/40/19, many many brands readily available, the same diameter of 27" and cheaper

255/45HR19
Load Index 100 = 1764lbs (800kg) per tire
Speed Rating “H” = 130mph (210kph) 100H SL Treadwear: 260
Traction: A

1764 lbs.
44 psi
12/32"
28 lbs. 8.5-10"
9"
10.2"
8.2"
27"
773

255/40ZR19
Load Index 100 = 1764lbs (800kg) per tire
Speed Rating “Y” = 186mph (300kph) 100Y XL Treadwear: 320
Traction: AA

Did this mess up your ABS by raising the front end up? Chev tech division does not recommend aspect ratio or rim changes.

GM Told me no way because the aspect ratio change will mess with the abs among other things.
Who did you go with, BF Goodrich?

gsp · 03-10-2008, 12:39 PM

wrong!

255/45 is an odd ball,,,,,, 255/40 is the SAME diameter as 255/45,,,, 773 vs 769 rev/mile on this one example

Hate to tell you this but I don't always believe what GM tells me.

Use the search tool on the upper right of your screen and you'll find tons of threads/post on the subject of tire size.

gsp · 03-10-2008, 12:51 PM

the "Chev tech division" is incompetent

hdflstf · 03-10-2008, 12:54 PM

GM is correct about the aspect ratio change (well, sort of). In a generic sense, they are correct. The problem is that in the case of our front tires you can get a 40 series (aspect ratio change from 45 to 40) BUT the overall diameter is the same. So the ABS will think there is a 27 in tall tire up front and will respond accordingly. A change to a different 27 in tall tire will not change this.

I do not wish to get into dynamic response of ABS discussion with you but even a 1" diameter change will not effect ABS to any measurable degree, as long as, the diameter "change" is the same on all four wheels. 0.5" diameter change difference is OK between front and rear

No need to discuss that as it has been beat to death before. I'm just pointing out, regardless of what the math associated with what the tire manufacturer prints on the sidewall of the tire a 27 in tall GY RSA is the same diameter as a 27 in tall (say 40 series Dunlop for instance). Of course, that dead horse has been beaten into submission as well.
