Hi guys,

So I'm normally a safe and sensible driver but today I found myself in a tricky spot ?? I was coming round a hairpin bend on a VERY steep hill (25-30 degrees perhaps) and I had to stop as the road narrowed and a car came the other way. I tried to go up the hill after that passed but I had 4 passengers and loud music (couldn't hear the tires) and my tires just spun (on dry tarmac) for about 5 seconds and was enough to generate a fairly significant amount of smoke at 3k RPM at which point I cut the throttle and went back down the hill in reverse. I pulled over straight after and the tread depth seemed very slightly less and the tires were very warm but no tears or anything. How much will I have shortened their life by?
