Help me decide on what tires
Ok so im fixing to need new tires for the racestars that are on the Trans AM. It has 275/60r15 on the rears and a 25.7 tall front tire. Needless to say it throws the abs inop, tcs, and brake lights because of the size difference. However when it does that I feel like I have almost no brake pedal at all.

I like the 28 in tall tire on the back but since we cannot run a 28 on the front from what I have seen I'm leaning to a 275/50 just so I do not the tire size difference issue. Normally it wouldn't bother me but my mother sometimes jumps in the car and I do not want to take any chance with the brakes being so weird (the ta stays back home while I am at college). Thoughts? And any pictures of a 275/50

Also is the brake thing normal or should I investigate. When we swapped motors we pulled the k member and I took it to a shop to have them purge the abs system of air.

275/50 QT Hoosier. Just put them on 15x12's and they measure only 25" diameter. Too low profile for best traction but I had them for another car never used em so i'll use them up.

I had same problem with braking after putting drag wheels on my Hoss. I pulled the 40 amp abs fuse problem solved . No more death pull to the right under hard braking. When I put the stock wheels and tires back on abs fuse will go back in. Back to normal abs function
