Hi i need some advice and help if possible.I own a vw transporter 2.5tdi t30 174ps lwb.I have recently bought a set of genuine vw touareg siena alloys.They are 120 x 5 fitment for my van as they were on a touareg 2.5tdi..The tyres are 275/45/19 with pirelli p-zero extra load 108y.Will the tyres rub on full lock or if i went over say a speed bump.Would 255/45/19 tyres rub if i changed to them.Do i need spacers and are these alloys strong enough for my van even with extra load tyres on.Any help i would be very grateful. cheers johnny.
