Thanks u all so much, vr2 and dab
Today i go survey tyre shop and ask advice for rim. I asking why two of these same inch rim, but different prices so much. He said one is import rim, one is local rim. Different is material to produce these rim. Import rim got mix with alloy material, weight less than local rim. So if take import rim, car will improve FC cause car weight has reduce and more steady when driving on highway.. Is all of that true? sifu?
Some more, he suggest, if take 16" rim, take 195/50 with tyres. That's will improve FC as well, is that good?
Hope can learn more from u all sifu, thanks
im not good at rims.
these days putting 16 inch is expensive, tire is nearly the price of 17inch.
but 16 inch with 205/45 is the best fit and the corner is really sharp and 205 grips good for this car, im afraid putting 50 series might be a bit of issue because its a bit taller, frankly im not sure about clearance and if any scraping or rubbing might happened.
45 series rides a bit harsh. but sharp control
mine is 50series with 15inchers. it compensate some ride comfort from my stiffer spring. cornering not bad though.
to be on the safe side i use t from other brand car standard 15 inch rims at the same hole size (pcd 100) and shod wit 195/50. 50 series is sharp at corner but you will experience a sharper turn with 45
but if u go for after market light weight, light weight rims although made in taiwan or korea or local the wheel will be embossed with the word 'light weight' and the rim itself 1000rm plus.
if you have wider tire of course its heavier, to compensate,,use lighter wheel. and if you are talking FC then i would say +- only marginal effect due to the wheel.
but if you are using taller tire it might give a slight batter FC in a long distant highyway . but FC might suffer a bit in stop and go town drive since the gearing ratio is taller now due to diameter of the tire increased . and initial push for the car is heavier and also might effect acceleration. - theoretically.
