good evening!
I have a mitsubishi evo 1 and have 215/45/17 tyres on front and 205/40/17 on rear.
Does anyone know if this will cause any problems to my 4wheel drive transfer box as i have been told its possible ?
Any info would be appreciated!!

 

find a website that can calculate the difference in tire sizes. A general rule is if a tire doesnt change your speedometer reading than it would be fine, but you dont want the front and back tires rotating at different speeds, that will kill your transfer case in no time. To be safe id stick with same size tires all the way around.
