Hi,

I recently got a defender which came with 235/85 16 tyres mounted on 16x7 steel wheel presumably from a Disco?

Anyway my question is will these larger tyres cause my speedo reading to be out slightly? if not what will?

Cheers, Happy New Year

Alright people CALM DOWN (I am new to forums)!!

I have done some research MYSELF and found my speed to be 70mph with 190/100 16 (original tyre size???) and my new tyres 235/85 16 are 70.83mph.

So when travelling at 70mph I am actually travelling at 70.83mph-1mph over what my speedo actually reads.
 
190/100's fooking hell where did yer get them from? are yer sure they weren't 7.50" 16's

and you coonts need to research yer research FFS. 190/100/16 is (as I said) 7.50/16 crossplys. which were never made in Metric sizes. yer fooking morons.

radials only goto about 85% of the tyre width, so a 285/65 is 65% of 285mm. + the Rim size in this case 16".
