I found a great deal on 4 285/60 R18 tires. A friend at my gym runs the same size tires and I must admit that size looks way more impressive than my 245's. however he warned me that the bigger tires might be a bit more of a strain on the suspension, but that was just a hunch he had. So, besides making a slight trim to the wheel well cladding, have any of you regretted opting for he larger tires? Any major (non-cosmetic) drawbacks? Thanks
