changing to larger rim

[michaelkomodo]

hi bro n sis, i've change my rim from 13" (tyre 175/70/13) to 15" (tyre 195/55/15).. anyone know how to calculate the speed?

wat i mean is, 110km/h on 13" may not b the same as 110km/h on 15".

thanks

remember to scroll to the A tire size calculator to calculate

what i did to compare 13" (tyre 175/70/13) to 15" (tyre 195/55/15), the result says that when your speedometer read 110kmh, actual speed might read slightly faster at 113.88 kmh

mayb shld try 195-50-15....

JIN is right..

done calc using 195/50/R15 gets a 0.14% variation... meaning for 110kmh travelled you can see
110.154kmh... can't see much actually in the speedo

finally, i shoot on the right spot... thanks bro...

too bad, i'd changed to 195/55/15 before asking this question... but thanks a lot on ur replies...

wat tires u change..?? just sell it off then get the 50 1 loo... if Neova, i dun mind buy from u... hehehe...

me got from calculations... you got frm experience

no biggie.... just remember to maintain slightly below the speed limit lor

or you can sell it to jin hehe

Wah , why you get 55 series bro ?

been wondering the same thing...:hmmmm:

but for me, if i do have a car that look good wif 15inchers, i'd go for 55 series... guess i like a chunkier look

bro's...i think it wouldnt be so accurate on the calculations...

if ur using 195/55/15 against the new bigger rim of 215/40/17 you will experience slight decrease in pick up but better top speed due to rotational mass of the larger rims..

according to the calculator, 15' is traveling 70mph and 17' will be 73.34(roughly)...wouldnt u guys think that the 15's are easier to spin than a larger wheel?

Lol .. there should more constant variable ..asumming both are lightweight rims

the calculater i've featured is to see how much variance in the speedo when you upsized/downsized the driven rims thats all.. no relationship to the performance in any way....

i've heard that in some country if you upsized ur rim and its produce more than 5% variance in the speedo reading is illegal...

hehe... witout huge power output, even i give it 18" still can't reach 230kph in a stock Myvi loo...

ur car speed reading is the same in any rim size ,only ur rpm wil be different when u change gears,pickup wil reduce and many more.try maitaning this size tire in ur 15 inch rim-185/50/15.it wil b lighter.........
