[QUOTE="t2ribena, post: 350559, member: 3847"] maybe the tyre you bought is not the correct size to stay within the 3% rule when going 1 size up...larger diameter mean larger circumference thus affecting the fixed speedo meter... based on your observation your speedo is under-reading and this means ur wheel/tyre overall diameter/circumference larger than the original wheel it designed for...check the thread width and series...normally if u get the same width, the series should be lower then for bigger rims...
