Thread: Tire suggestion

  1. #1

    Tire suggestion

    Currently running stock size tires on

    Bilstein Pro with H&R sport touring (.75" / .25") with 15mm spacers in rear 10mm front.

    Not rubbing much but it is very tight in the back. Looking for tire suggestion for the front and rear without losing too much rubber.

    Stock setup
    255/35 rear
    225/40 front

    Thinking maybe
    245/30 rear
    225/35 front?

    A lot of folks on here will say run a square setup. I am certainly in that camp. I'm on 235 squared.

    Not the widest setup by a long shot. But the car is very neutral, easy to control, and it doesn't break the bank.

    I do 245/35 18 square as do many. Closest to OEM ratio.

    yes, but it could break the rear end loose.

    personally, i'm on the fence about square vs staggered. my thoughts:

    STAGGERED (does that mean off balance? )
    how it came from the factory. awesome steering feel (well, dependent on tire choice), safer. the rears wear faster on our cars so it means you're doing 2x as many rear sets of tires as front sets. and if you're running directional tires, no ability to rotate the tires anywhere else on the car.

    SQUARE (wait, aren't they round?)
    better ultimate front end grip, and tire rotation-ability; if you're running non-directional tires, you can put rotate them anywhere.

    my take on the whole frig
    i'm running a 245/38/18 'square' setup, on 18x8.5" wheels. 3mm spacer in the rear. at first i thought i would try this setup for better tire rotation abilities and increased front end grip - which there definitely is - but now i'm not so sure i want to stay here. when i'm pushing the car - man, that increased front end grip is great! but the other 95% of my driving is done sedately, and i find that the square setup is a bit twitchier feeling - plus 245's up front kind of numb the on-center steering feel. so i might go back to a staggered setup to gain highway some on-center feel and more relaxed highway manners.

    that's a 0.6" different in outside diameter - pretty huge.

    it is and it isn't. let me explain:

    stock:
    225/40/18 = 25.1" OD (front)
    255/35/18 = 25" OD (rear)

    or:
    245/35/18 = 24.8" OD
    235/40/18 = 25.4" OD

    so they're kinda equally close.

    Did you feel that way about my 255's as well when you drove it? My steering feels great to me, which is why I'm curious if you felt something I'm not feeling with my setup.

    yeah, i felt like your on-center feel was more numb than mine, but that could be other factors: tire pressure, tire construction, width (although my 245's are WIDE) steering coupler condition (mine is new), alignment settings... your car felt similar to mine in that as soon as you're past that numbness, you can feel that extra tire digging in.

    here's something interesting:

    on my Style 68s (staggered), on my Touring, i ran 225/45/17 and 245/40/17 tires. the steering feel was awesome - no numbness on-center, and it felt very direct on turn-in, and stable. same car, same setup but with my square winter setup (215/50/17), and while the on-center steering feel was decent (skinny tires), the car didn't feel as stable.

    very weird.

    I'm also in your 235 squared camp...

    I've been happy with it. I'll likely stay squared on my next tire change.
