I've searched, and can't find an answer on this:

Is there any reason not to go with a 245/45-18" tire on an 18"x8" wheel with + 40 or +45mm offset ? Will they fit without any rubbing issues?

I'm considering ASA GT14's or Voxx Orso's. (I'm leaning toward the ASA's.)

Thanks in advance.

On my Acura it has the Acura 19" rims instead of the 17" without any problems.

I am running Firestone Firehawk AS 245/40R19 tires.

Thanks, mdd. I forgot about the stock 19's being 8" wide and 245"s. How noticeable were the effects of the heavier wheel/tire combination on acceleration, braking, and/or fuel mileage with the 4-cyl?

It increased noticeably all around.

Your speed will increase also, the higher the speed the larger the increase..

Gas mileage increased about 2 mpg on highway driving.

I didn’t notice a change in fuel mileage when I switched from 18s to 19s. They are noticeably heavier compared to the 18s though so I’m guessing you’d notice a good difference going from 17s.

I'm only going to step up to 18's. That seems like a good balance between appearance, cost (wheels and tires), and ride quality. The car will see a lot of highway and plain old general use. I don't it to be a corner carver. (I have my Mustang for that.) :)

You should be fine. Here is the chart for stock options. 45 mm offset will make them look even better. Check out tire rack, they got a big selection of aftermarket rims. Make sure to look at a weight of a rim, sometimes they are heavy as hell and will kill performance and mpg.

Thanks for the reply. I don't want to put a lot of money into the wheels, so nothing I'm looking at will be ultra light, but even so, there is quite a difference, you're right. Funny thing is, some that look like they should be lighter than others simply aren't.
