..... But other than that, I don't see much of a problem!
I didn't see my post, so I will post up again. I just had the same dilemma on my wifes CX9. I swapped the 2 rear for 255/50/20 to see how it would look. It really looks about the exact same on the car as the stock 245/50/20. I wanted the 265/50/20 but the price was so much more than the 255 or the 275, or at least that was the case for the Yokohama Prada. I do not have an AWD so I am considering putting 275 on the rear and moving the 255 on the fronts. I may just stick another pair of 255 on and leave it at that. If I do, I don't feel I gained what I was after since again to me it looks the same as stock.
Remember that each brand differs in sizes too. 265mm wide is gonna be different on Nitto vs General...etc.
On my G8, 245 is stock. I went from 245 to 275, noticed a nice difference in width. Recently just went to a 295, and it looks awsome.
Did it affect the car handling and the mileage?
Anyways, it seems I'll go with standard 245/50/R20, but on one of the shops I've visited, the dealer there showed me 2 tires of the standard size of the same size, but one of the was wider than the other, seems i'll opt to buy that one, the wider one, but does anyone knows why it is wider though it has the exact size? think it was either goodyear or bridgestone don't remember myself.
