big rims, slower speedo readings?

zerocool85 SG

does big rims equate to slower speedometer readings???

by how much difference?

i doubt so dude!!probably you tried faster car..

If you get the wrong tyres, you’ll have wheels with a circumference that varies too much from the original. With every turn of the wheels you’ll travel a greater or smaller distance. Your speedometer will thus be rendered inaccurate.

I think to minimize speed difference to the speedo, try not to go beyond manufacturer’s wheel spec available for your car, ie Mini has wheels in sizes from 15” to 18”.

So that's why TP generally don't catch people who exceed speeds limits by 10%? Wink

Bigger rims can, but u have to use lower profile tyres so that the overall wheel diameter stays around the same, and therefore ur speedo wont vary too much. Recommended you stay within 3% of the stock wheel setup.

the reason why i posted this question was.. i met with some speed problem for the past 2-3days..

i have not been going up to high speeds for a v.long time...

but yesterday and today, decided to give it a go..

from bowen sec sch.. to the right turn to srg gdns.. i only managed to hit 130-140km/h.. but the thing is, the speedo readings did not feel like it was 130-140. it felt more like 150-160km/h.. or maybe im wromg also.. it cld be 130-140.. cuz ive not been above 120 for a v.long time..

but it does seem wrong that the stretch of road allowed me to acclerate to such a low speed..

any advise???

i drive mz6..

Next time don't pull of such high speed "experiments" there cos i frequent that road every weekend.

Its a freaking 50kmh speed limit road there for God's sake.

Wanna do something like that make your way over to LCK past jln bahar.

zerocool85 SG

i live near there.. i know the road conditions... thats why i pull such stunts..

yeah i know its dangerous and stuff.. however it was already 4am and its as dead as lck 40 tiang

if you choose/calculate your upgarded tires/rims, you should be able to match back to your stock quite closely +/- a little.
