I travel on a dual carriage way most days (its my way to work and into the local town centre) and I noticed a 'slight' wobble on the steering wheel.
I had just had two new tyres fitted to the front of the car and originally thought it must be the balancing that was off. I know that Vec C's are fussy about balancing.
Check the tyres over first before going back to the garage and couldn't see anything obvious. Thought I may as well check the rear tyres while I was at it.
I found this......
Tyre had 'bulged' in 4 seperate places!
Went back to the tyre place and the first thing the guy said was "Erm, think you may need a new tyre on that!"
