The previous owner of my Mitsubishi L200 4x2 Single cab changed the wheels from the original 14" pressed steel wheels

It seems to me that i'm driving faster than the displayed speed. Does anyone have a simple way of telling me how far out, if at all, i might be?

Thanks

buy or borrow a road angel speed camera detector to display your speed

Or if you have a smart phone there are a number of apps linked to the GPS built into the phone which will display speed.
Or a great free navigation app is HERE maps developed by Nokia originally you down load just the maps you need so no streaming charges. I use it a lot when I travel in Ireland in hire cars on business.It displays speed which is the point of this......

You only need use it for awhile, then add a note to identify where 30/60/70 actually are on your speedo
(or as tractors) work out from rev counter and gear you are in,
how fast you are travelling

Another option maybe, find a place on the dash to mount a Scangauge or similar, apart from giving a speed readout there's other features, it can read/clear some fault codes too,.....all assuming that the vehicle has an OBD2 port in the first place.

Mathematically, the new tyres should be only about 1.3% bigger, but a GPS speedo on your phone should confirm it.

Thanks for all the suggestions, i will checking to see if i actually have a OBD2 port?

Whoops. That should read 10.3%.

somewhere lowdown on dashboard maybe below steering wheel or glove box

If it's a 2005 vehicle, it should have one. You may have to remove a piece of plastic/trim to see it first but it should be within reach of the drivers seat, I believe that were one of the rules.
