Sorry to be posting here, I would jsut like to get some more eyes, some of you may not read the Seville\Eldorado forum. I have a 96 Eldorado.
I just picked up some 18"x7.5" wheels and I need to buy some tires this morning. A lot of guys have been helping me decide and I really appreciate it.
Discounttire.com says that I can go with a 245/45/18 or a 235/50/18. The only difference is that the 45/18 is going to have a difference from the original diameter of .23% (60mph will be 59.8) and the 50/18 is going to be 2.32% (60 mph will be 58.6).
I am leaning toward the 50/18 based on ride quality, price, and selection. I would just like to know if I am going to take a huge performance hit with the 2.32% and will my mileage really die if I am getting about 22-23 mpg on my 16s?
