Going from 14s to 17s....speedometer off?

[andrew16]

Sup guys,

I'm plannin to put on some 17s on my MR2, but right now i'm running on 14s. My speedometer is already off as it is but will this increase change it drastically?

If it does, how would i adjust it to the correct speed?

Thanks!

wheel size is irrelevant
what size tires are you coming from/going to?

there is a calculator on teamintegra. I can plug the numbers for you if you aren't a member.

Yeh, iirc, it depends on how close the overall diameter is to the oem tire/wheel.
