My wheels came about a week ago and I have yet to get some tires because I can't make a choice. My wheels are 20x9.5, Tire Rack and HRE both reccomend I use a 265/30/20. The only problem is there isn't a very large selection of that size tire. So my question is, would there be a problem if I went with a 275 series tire? Is there a noticeable difference between the two sizes?
