Staggered Tires and ABS?
 

I'm considering getting some shiny new 15” x 8”-wide wheels and different tires on my 2-door 1996 2WD Blazer. This is a street vehicle. I'm currently running T/A Radial 225/70R15s (27.4” tall) on 7”-wide wheels. They're nice but look a little bit small in the wheel wells. I'll step up to four new factory stock size 235/70R15 tires (28” tall) on wider alloy wheels.

However, I'm wondering if I can get away with temporarily using my two newer current tires on the new front rims and put new 235/70s on the back. (I might lower the back end slightly to level the vehicle.) The 225s are just too fresh and nice to not use up. The diameterdifference--front-to-rear--would be 0.6”. The revolutions-per-mile difference would be 15. (The 225s turn 758 revolutions; the 235s turn743 revolutions.) That's 0.02% difference. Do you think the ABS would notice this? Would I see a trouble code or have some braking issue?

Also, I'm curious about where the ABS controller is on this Blazer. I'm not aware of a separate control module. Is it perhaps incorporated into the ECM on this Blazer?

Thanks,

Rob
