I had slicers on my car most of the summer, with Kumho 732 Touring Plus tires (brand new) on them. I noticed that when I first put them on the car would squeel quite a bit if you floored it off the line, but after awhile they no longer did (about 5,000 miles). I just put the stock wheels back on with brand new BF Goodrich tires, they don't squeel at all (never have with stock wheels) - but I was surprised, for some reason the car seemed to really get up alot faster. I never noticed if the 16x6's were spinning at all and they seemed to grip the road fine, but the stock 16x6.5' wheels seem to stick like glue and the car seems to get to 70 a lot faster now.
I also noticed that the BF Goodrich (which are twice the price of the Kumho's) are a lot louder than the Kumhos, I would assume this is because they are a bigger tire and have more rubber touching the ground than the Kumhos. The ride is also a lot rougher, bumps are far more noticeable and the car seems to move up and down with the surface of the road.
Could it be the quality of the tires that make the difference in performance or is it the size of the tire that could be causing this difference - or a little of both?
