Yesterday, (28 Oct 2022) i got new tyres from Rob's Tyres (pretty good deal, I think) on recommendation and facilitation from Antony and Tinus, respectively (Thanks btw
). They are Maxxis Razr AT811 265/70r16. Funnily, they were exactly the same height as the old worn down BFs. 265/75r16s would have been 25% more expensive, which was too painful for me at the moment. On the first trip back to Joburg they seemed smoother and quieter than the BFs 
, but sadly the wobble was not gone 
. I will see how they do in rain. The speedometer and the RPM readings (100km/h @2150 RPMs) were exactly the same as with the old tyres. Well, not surprising because thet are the same height. However, the GPS reading (i use WAZE) was 90 km/h (with Maxxis) instead of 95 km/h (with BFs) when the speedometer showed 100km/h. And now the funny bit
, the tyre size recommended by Nissan (label in the door) is 235/80r16, which is the (almost exactly) the same size as the 265/70r16. So, i would expect that the speedometer is calibrated to this size. Hence, be closer to the (true) GPS reading. In fact, i expected that with a larger tyre (compared to the recommended/calibrated one) the speedometer would "underread" (100 km/h when really going 105 km/h). Am i totally off here or are the errors of margin so large that this makes sense in some way?
