I'm using 15' 195 55 tires for my Lancer and would like to change to profile 50 for my next tire change,I noe that it's not the correct profile and speed and millege readings would be affected.
But I would like to know when I switch from profile 55 to profile 50.Would the speed readings be over stated as in indicating I'm travelling at 100km/hr when I'm actually doing 110km/hr?
Oso will the millege counter under or over report the actual distance travelled?
Last is would the discrepancy be a lot from original readings?
