First off, I'm a tyre technician/mechanic apprentice with a large garage in Wellingtn NZ. The past few days we have had torrential rain that has created surface flooding on the roads. Not a big deal if you are sensible and keep a safe following distance.
But people with bald tyres and low tread depth are endangering peoples lives in this sort of weather. In the wet, travelling at 100kph, the ideal following distance is 4 seconds in order to stop safely if the guy ahead of you stops suddenly. With bald tyres, you are effectivley increasing that distance to 10 seconds.
I know I'm probably flogging a dead horse here, but at work we have all been hit with a problem. A guy came in for a Warrent of Fitness last week. Failed on 2 front tyres. We offered to fit him two tyres, but he wanted to shop around. Fair enough. We let him go. Yesterday, he was involved in a nose to tail. In hospital with two broken legs, broken arm, fractured rib and a strained back. Kinda opens your eyes a little and makes you realise what you are actually in this job for.
So, instead of being a moaning little boy, just make sure that your tyres are in good condition, pumped up to 30psi (its what we keep most tyres at in NZ, not sure about UK and US), and get a wheel alignment every 6 months or 10000km so you are not getting uneven tyre wear and suspension issues.
I'll get off the box now. Ahhhh, thats where I left my hat and coat....
