Some of your pros/cons aren't really that meaningful...1. Tires. You can put whatever tires you want on any of the cars. You do not have to stick with the OEM tires. There are better and less expensive tires available. As long as you stick with a comparable tire (size and load index), you'll be fine.2. 0-60 times. Unless you're going to take the car to the dragstrip or are constantly racing for pink slips, all three vehicles will have comparable acceleration times (within .5 seconds) to not make a difference with normal, everyday driving.3. MPG. Since the Altima requires premium unleaded, your fuel costs will be higher than the other two cars, even if it still got better gas mileage. Also, gas mileage very much depends on your driving style. According to EPA estimates, the Accord has a better gas mileage rating (19/29) than either the Camry (19/28) or Altima (19/26). Regardless, all three are close enough that it shouldn't be a factor.I would recommend test driving all three (if you haven't done so already) and see which one you like better. Each has its own strengths and weaknesses and each person has different priorities and preferences. As an example, my mother owns a Camry. She test drove all three and liked the ride of the Camry better than the other two. Meanwhile, my sister has an Altima, which she liked better (felt it was sportier than the other two). I, on the other hand, bought an Accord. I liked the styling of the Accord better (both interior and exterior) than either the Camry or Altima.In addition, from an overall reliability standpoint, the rankings (for these three) have historically been:1. Toyota2. Honda3. NissanThe current Camry has had quite a few problems, which (to me) meant that the (2007) Accord was the more reliable of the three cars. I think the 2008 Accords are too new to determine if the reliability is better, worse or the same as previous Accords.
