Maybe a dumb question...maybe not!!!

Bought 5 new LR 16" wheels with Michelin rubber on them for my '03 disco. Currently have the 18" wheels on my Rover.

Soo, if I change the tires from 18" to 16" will the speedo still be calibrated properly or do I have to tell the computer that the wheel size is different???

Or, will I be stopped for speeding every 4 weeks???

As long as the overall tire diameter is the same, you're speedo will be fine.
What tire size are you running on the 16's? I assume you had 255/55R18's before.

If they are different tire sizes, you can use a handy tire calculator to see what your difference in mph is.. I usually use this one from a miata website [its the first one that pops up in google]

255/55/18's on the old rims and 255/65/16's on the new.

Using that calculator it actually looks like the cancel each other out, so your speedometer should register the right speed at all times

I dunno about you guys, but I'm not worried about breakin' many speed limits in my '96..

lol... 8 years driving my camaro = no tickets, 1.5 years driving the rover = 3 tickets, and who know's how many times I've been pulled over in it. What's up with that?

Yeah I got a speeding ticket with my rover within the first month of having it! Cop tried to pin like 60 in a 40 on me.. I asked to see his radar and it was only marked at 50.. he's like "oh well, when i first shot you i got 60, but i locked at 50" .... [asshole judge, but he still let it go at 50]
