Bigger tires in rear make turning worse?

    I was told today that if i got 315 on the back of my hellcat that it would hurt the performance when it comes to turning because i wont be able to turn at faster speeds. I dont know if this is true because the 2014 z/28 has 305 on all 4

    This makes no sense. Why would it not be able to turn with bigger tires?

    theres some thoughts about staggered tire sizes front to back and its affect on handling. maybe that's what he's talking about?

    Yeah i think so because i was talking about staying 275 up front and having 315 in the back and he told me i shouldnt go more than 295 because it would affect the handling of the car

    The Hellcat has a lot of weight on the front end compared to the back. If you run 275/315 tires on the car and corner at the limit without changing other suspension components to rebalance the handling it will understeer pretty heavily. If we're only talking about handling on the street at reasonable speeds I doubt it will be an issue for you. At an autocross it would be.

    Do you run your car on the track? AutoX or road course?

    Ok cool, just wondering since you were upgrading your suspension.

    OK, but if you want to run 275/315 tires and have near neutral handling at the limit you'll need to stiffen up the rear roll stiffness and/or lessen the front roll stiffness. Do you have a plan to do that?

    I put bigger tires on the back of mine and I couldnt turn at all.. had to drive straight all the time. crazy!!

    but really, the 70 TA challengers and AAR Cudas came with staggered wheels from the factory so they could race like that SCCA. If there was a problem then I doubt theyd want to do that on a race car.

    None of those will change your front to rear roll stiffness balance unless you go with a smaller or hollow front bar or have custom springs done for the KWs.
