Front tires 14"

i think the reason is that there is alot more 15" wheels out there :( as a sidenote you may not have the same problem as i have but with aluminumwheels in the front and my stock diskbrakes i cant put glued balance wheigths on the inside of my frontwheels since they will hit the brakecallipers.
i have always run radials in the front but i cant give you that advice since i have had some pretty crazy things happening on the road when running radials in the front and diagonals in the rear it can get very ugly very very quick. if you just whant something tall and skinny you may want to look at what was on old volvos stock, they have tall and skinny front tires
