MX5 1.8
had my 15s on and been on the motorway at high speeds, it feels rumbly and shakey every few seconds, has this got anything to do with the wheels or is this normal? it only happens at high speeds, and is the speedo correct? ive managed to get near 117 on a 1.2!?! i was struggling to get to 110 on my 17s! any suggestions people?
thanks joe
