just looking for some quick maths..

running 30' on a 97 seirra..

if i drove 1km on the dash, how far have i actually driven, taking into account the larger tyres.. does anyone know exactly how far out it is?


cheers guys

Assuming the dash is 100% correct for stock 26" tires and your tires actually measure 30" then;

30/26 = 1.15 thus 15% oversized. Therefore 1km on the dash = 1.15 actual km
