smaller wheels?

[Ldub]

First things first...

Welcome to the Fam...

thanks guys,
and just to make sure,there shouldn't be an issue with speedometer or messing with the TOD/ABS systems or drivetrain?
i heard going bigger had effects on those things, but going down in size should not be a prob?

Here's how it works...going up OR down in size from stock will have an effect on your speedo/odo...
A tire with a larger overall diameter makes fewer revolutions per mile.

A tire with a smaller overall diameter has to make more revolutions to cover that same distance.

I hope this will help, rather than add to the confusion...

Stock 99 tire : 245/70x16".....29.5 oa diameter
Stock 00/01 tire : 245/60x18".29.57 oa dia.
........................265/70x16"..30.6 oa dia. (common upgraded replacment size, with a little trimming)
........................285/75x16"..32.83 oa dia. (common upgraded size, w/lift & trimming)

All the above info. is for stock rims...an aftermarket rim with a different offset (usually more negative...towards the outside of fender) will throw all the lift/trimming info. completely off.
