I agree - exactly thesame problem on mine - speedo reading 10% high. I am thinking of fitting 225/75r16 AT2's on my XT. Has anyone else fitted this size?bugone said:I will fit bigger diamater tyres when I need to replace them.
The speedo is way out on the standard sized tyres. 70 on the dash was reading as 64 on my gps, so slightly larger diamater tyres would make the seedo MORE accurate.
