ok here's the prob. i used to have 215/60/16 tires all the way around. and now my driver side rear tires blew up. i need a replacement. so i'm thinking about putting 255/50/16 on the back and leave the 215/60/16 in the front. will this work? the guy in the tire shop says that it can mess up the ABS? i need answer quickly so that i can order them today...thanks a lot guys

 

Why would you have 215/60/16s???? Stock is 235/55/16 or 245/50/16, take your pic. I'm unsure about the ABS deal, but it's a possibility, but I know it will affect your speedo. Tire salesman don't know much, trust me I work with them everyday.....

 

Not sure about how ABS would be affected. I get an ABS Inop on the dyno and usually after a long burnout.....

That being said, 215/60 is not the right size for your car. No camaro ever came with a sad little size like that... 235's or 245's were stock on 16" 245/50-16 is the ideal size on 16" wheels.

Good luck,

Michael

 

yeah i know, but the dealer that i bought it from was to cheap to replace it to its normal size. so nobody knows how it would affect the abs???

TTT for me

 

Unsure...

 

TTT

 

it shouldnt affect it, i blew out my front tire and havent had the money to get another yet, right now im running 275/40/17's in the back and 245/50-16's up front, it hasnt had any affect on my abs.

 

dont your rear tires spins more than the right?? if it's really ok, then i'll order them tomorrow....btw does the car handles funny???

 

There is no difference in outside diameter between a 275/40-17 and a 245/50-16, so there is no way it could affect anything, other than the subtle difference in handling.

The skinny 215/60-16's are 26.16" diameter, about 1/2" larger in diameter than the stock tires. 245/50-16's are 25.66" diameter. This should not affect ABS. I run a huge variety of tires on the front and back of my car, between street and track tire setups, and there is no problem with the ABS.

If you think about it, ABS is not activated by simple differences in wheel speeds.... its activated when one of the wheels appears to be stopping, and the others are still turning. Its only when the signal from the wheel sensor starts to approach "0" that the EBCM is going to do something to stop the impending lockup, not when one wheel is turning about 2% faster than another wheel.

 

On the topic of ABS, I have an ABS problem. Everytime I drive the car just about (4 out of 5 times), when I first drive, when I get down to 5mph when braking, the ABS kicks in HARD, even though I'm not skidding..... it "releases" the drivers-front brake, and no matter how hard I push I can't stop the car til the ABS is good and ready....

After 3 or 4 occurrences, the car goes into ABS INOP and at that point braking works just fine.... its definitely the ABS.

What do you think, sensor on the left-front hub??

Thanks,

Michael

 

Definitely a sensor problem. I had a similar problem with my Strange 12-bolt, until I got the rear sensor adjusted correctly. Everything worked fine until about 10' before the car was supposed to come to a stop... then the ABS would pulse the brakes, and I'd end up taking about 5' extra to stop the car. It was a problem with the rear sensor, which Strange supplies with the ABS option, and isn't the same as stock. After I moved the sensor a little closer to the reluctor wheel, the problem went away.

 

so if i put 255/50/16 in the back, it wont affect the ABS?? thanks man

 

didn't read this thread, but I am 100% sure it wont effect the ABS as I stated in the lounge


"I ride around with 245/45 up front and 255/50 in the rear. no ABS problems.

I've driven around with 245/45's up front and mickey thompsons in the rear.

People here have 17's up front and 18's in the rear.

[edit]

if anything it would effect the ASR or any other traction/stability program. However I cant see it doing that (mainly because I dont have a problem and I do it!) and the fact that ASR senses to see if the rear wheels are moving FASTER than the front- ie a spin condition.
with 255/50s in the rear, the RPM of the front will be slightly GREATER than the rear.

ABS works when you are above 20mph and it sees that you go from 40 to zero (it tires lock up) or something like that. "

 

i have 17 front 18s rear, no probs,

you just have to stay within about 15-20%, and the abs will be OK.
and thats a pretty big margin

No, the ABS system has no clue what size tires you are using. It reads the wheel speed and adjusts accordingly. You could run whatever size you want. The computer has no clue what size tires are on the car, and it doesn't care. All it wants to know about is, is the wheel speed at or near 0 mph.
