Wheel/tire Sizes Need Help

[Whitetigerboi83]

Ok i have 205/65r15 on my stock steel rims .. i bought the 15's from white[attachmentid=9917]
now since they are 16's and i cant put my 15s on them i'm looking to get wheels right size as to not mess up my speedo and milage.. i'm dumbfounded on how tirerack trys to explain (or most tire sites) the aspect ratio ect ect.. so if anyone can help better explain this it would help but from what i could tell if i were to go with 205/60r16 that would be aprox the same size compaired to the 20565r15 i have now full tire dimeter correct? i'm so confuddled... . but any way i was looking at goodyear assurance tripple tread but i may not spend quite that much since i just put 350 dollars worth of tires on the stock rims.. .. but on the other hand i never know if i do get to put the rims on in the next few months i want to be able to spend to get the breaks upgraded and all that jazz....

thanks

edit: ok rethink this i want a smaller looking tire but not to much to f up my spedo and milage... so i still need help deciphering tire codes even if i have to get someone to reset the speed/tach to the new wheels or would it really matter?
