Well you got your concepts a little mixed up there my friend ..
Youre right , the dtsi is taller geared and there is drop in acceleration but there is a corresponding increase in top speed. And this produces LESS strain on the engine theoritically .. But the tire wear depends more on usage pattern rather than on such a small difference in gearing.
And I got my chain and sprocket kit replaced recently ( yes it wore out prematurely too ). So what Im planning to do , go for SIRAC rear which makes the bike taller geared and change to the fi's rear sprocket to cancel out some of the taller gearing when i have the money ( student , so funds are only through pocket money. Besides , ive saved up for joels FFE
).
But if one is changing the rear tire to sirac purely for touring purposes , i would suggest that you stick to the stock sprocket. you wont feel the acceleration drop on the highway. That way , the slightly taller gearing will give you better speeds at a lesser rpm and reduce the strain on the engine on a long trip. Hence , in theory, a marginal increase in FE as well ..
