Not happy with Tire Combo
I'm currently running 275/35-18's front & rear. I'm not satisfied with the way the car handles. Can't quiet put my finger on it. Just doesn't feel right. Tires are Kumho's with less than 500 miles on them. Plus looking at the car, its appearance makes the front tires look wider than the rear.
Kumho doesn't make an 18"bigger than a 275, so I was thinking of going with 265's on the front. Anyone running this combo and how is it working for you?

I could be wrong (and I usually am, just ask my wife or my boss), but I was always led to believe that the front tires/wheels are supposed to be smaller (overall diameter) than the rear due to potential issues with ABS and TC.
This stagger can be accomplished a couple of ways - by installing dissimilar size wheels or in the case that you want to run the same size wheel - changing the size of the tire. This is the way the car comes from the factory. The front OEM size of 245-45x17 is approximately 25.7" and the rear is a 275-40x18 is 26.8" overall diameter.
By running the same size front and rear - the wheel sensors are seeing both sets of wheels spinning at the same speed, and it is expecting to see the fronts spinning slightly faster than the rears.
Your 275-35x18 is 25.7" overall diameter (like the OEM front).
Now I don't know if this is the handling issue that you are aluding to (I doubt it). I'm simply saying that you are setting yourself up for a potential issue by running the same size tires front and back.
You don't say what width or type of wheel that you are running. Are they the same width all around? Is the wheel the appropriate width for the tire size that you are running? Is the wheel hubcentric? Are the tires inflated to the proper pressures? Are the tires directional - and if so, are they mounted so that they are rotating in the right direction? Do you have an alignment issue? You would know that by the way the tire is indicating wear. Do you have a balancing issue? Do you have a wheel that is out of round? Were the tires and wheels balanced on a road force balancer - so you would know if you have a runout issue?
There's a lot to the science of changing out wheels and tires beyond cost and what looks cool.....I'm not saying that I know it all or anything for that matter. I'm just trying to point out what might be bringing on your dissatisfaction in the handling. Good luck.

What Kumho's you got?
I had 275 Exsta Supra 712's on my Camaro and it totally destroyed how it drove.
Tracked horribly, felt unbalanced, and severely increased the amount of steering wheel force to turn. Any slight groove made it pull like mad.
Removed Kumho's and it went away.
