Thread: Not your standard tyre question

I've got 265/70/16 on my Disco and according to the gps on my phone the speedo is correct.

I got 265/75 I think or maybe it 70 but anyway my speedo is mostly correct it not till your up the 100km+ mark that it starts to go out it seems not sure if someone has previously modified it in some way or not but around town no preblem with an out speedo

I tryed em it corected the speedo but the odo was way out and I mean wayyyyyyyyyyyy out

I think you are correct there with odometer being way out as the other week was using a book to follow a track and odometer measurements between my vehicle and book varied on average about 100meters per km if not more

I started looking for fuel leaks it was that bad then the penny dropped and I checked the odo against the GPS useing aussie explorer not going to but super accurate but soon worked out what was going on. No big deal in the scheme of things but I'm anal about when my gear gets serviced and it was just too vague so went back to standard tyres I will go up a size again just not that large.

265/70 will give you approx.101kph with indicated 100, 265/75 will show approx. 102/103 kph with indicated 100.
Cost difference 245-265 is also bugger all.

Thanks all

I reckon I'll go with whatever I can get that's value for money.
If the cost differential is negligible, I'll shop around.
I'll definately go 265 for my next muddies, but I'll shop around for 245/255/265 for my AT's and just shop on price.

My Disco is fitted with factory alloys.
It has 265/75 16's fitted.

when my speedo shows 100kph. MY GPS shows 110kph as does my nanocom.

Speedo shows 50kph, gps shows about 55.

Seems to be around 10% low on the speedo.
