Hi,
Thinking of getting a set of these too. I have 275 40 20 fitted, will the increased side wall to 45 make any difference to speedometer etc ?

I have General Grabbers AT 275 45 20 fitted. I took my daughters garmin sat nav (as LR satnav doesn't give me the speed) and checked it against the speedo.

Speedo was at 70 and the garmin said 69 but that being said manufacturer speedos normally run on the high side.

you can check the difference here
