You essentially went from a 31 inch tire to almost a 32.5 inch tire which will make it seem like you have a higher gear ratio. I can't tell you how much of a difference it makes, but it will lower your rpms which may be making your truck trans shift more when encountering slight grades or hills.

Your more expensive option would be to install different gears, but that would definitely be more pof a pain and much more expensive than tires. You could turn off the overdrive function if you have that option also.

The dealer can do that, or if you have a good suspension shop, they can likely either do the gears, or recommend someone that does.
