chromes last forever if you take care of it and keep it polished and waxed. And no, your speedometer will not be wrong, Unless you git big ass tires. And generally the tire weighs more than the rim, so the 1 inch bigger will not add weight, it would be less if anything. 2nd, the design of the rim is most likely lighter than the supra wheels. To measure your wheels height, you take the tires size, 205/50 for example. the 50 means its 50% of the width in height. so the tires are 102.5 mm tall. Which is about 4 (25.4mm/inch). So the total height is 4+4+17(25"). The stock tires/wheels are 25.6" tall mathematically. The most accurate way is to just measure them, And apply the percentage as your speedo error. For the given example, it would be 3%. So at 50 actual speed, your speedo would read 51.5. Not much of a difference, which is why most people dont worry about it.
