abs not working service stabilitrak after new tires

[camaroboy1985]

hi i have bought new tires for my camaro ss 2010 and after that i got service stabilitrak service lights on and everything is off on the dash, abs brakes kicking when i start the car and braking after a few minutes everythings goes off on the dash how can i fix this problem please help?

i have bought 255-35-20 tires front and 275-45-20 tires rear, if i buy 255-40-20 tires should this be work?

It could likely be something to do with your TPMS. Though this is usually more of a problem with people who've installed new wheels as opposed to just the tires. What I'm thinking is that when your new tires were installed the wheels weren't put back on the exact same hub they came off. So, stabilitrac is getting mixed up readings and hence your car is having a panic attack. Take'r in for a TPMS relearn.

Either bring your fronts to 40 or your rears to 40 and you'll be good to go. They go off if there's that much of difference in tires

I think the manual tells how to reset the tire sensors. I don't remember how I did it when I put the BFGs on after the Perellis. I had the RS tires/wheels and replaced with the Factory tires/wheels. They didn't need any reseting I think you drive around the block and they are good to go. Isn't there a menu item that asks you if you want to reset the tire sensors? Can't you call OnStar?

yes. These cars are smart and you cannot have a big difference in circumference in the tires from front to back.

letting you know. The first number is the length side to side the second is the percentage from side to side from the ground to the wheel. Meaning you have the rear 45% of 275 while the front 35% of 255. The stock tires have 45% in the front for 255 and 40% in the rear for 275. If you have 45% in the rear got 275 you muggy need 50% in the front.

Take a look here for some good info on tire sizes for your camaro:

Like others have said, the overall height of the tire must be close between the front and back, there's no way around that.

Did you decide on those sizes or did the tire shop recommend what they gave you? If they told you that combo would work then I would get them to take the tires back and swap them for the proper sizes.

Stabilitrak is piggybacked on top of ABS, and both systems use the ABS wheel sensors. There is a little tolerance here, to accommodate things like tire wear and minor variations in tire size (there are, after all, several OE tire sizes to choose from). But too big of a difference between front and rear tire revolutions per km will throw the errors you're seeing. (Basically, the ABS and ST will think that the big tire end of the car is already sliding because the revs don't match or that the small tire end is closer to suddenly locking up when you're slowing because it's dropping rpms per km faster).

Elsewhere, I've heard 3% difference as being something virtually all ABS systems will tolerate. How much more any specific system is good for is just a guess for anybody who didn't actually work on its development.
