19" wheels tyres size and offset

[Campbell Westland]

Morning everyone,

Looking to buy a set of 19" oem alloys which have 255/40/19 tyres on them. Looking at door card on the car it states 255/45/19! Will these still work and not mess up speedo and such like. Also will they fit with ET43?

cheers

Your new tyres will be smaller than the originals, so yes they will alter the speedometer readings.

Hi Cliff the car currently has 235 55 18 on it, I was more curious as to if the tyres at that size would be OK after seeing 255/45/19 was on the door card
