If lesser than 400, check tire degradation yearly or every 10k km. It depends on road conditions and how you drive. More aggressive acceleration and braking will surely shorten the life of your tires. The stock Bridgestone HL 400 on my FXT had a 300 thread wear rating and I had them replaced at 39k km.

For those with 200 or less thread wear rating, they would be good for just 20k km. They are very grippy tires though but they wouldn’t last 2 years. I tried the Kumho KU36 XS before with a thread wear rating of 180, they were almost gone by 20k km.

Thanks for this. Learn something new everyday. I typically base tyre condition on the thread wear indicator but, I make it a point not to push it to it’s limit especially if I foresee it nearing replacement approaching the wet season or abnormal wear even with some thread depth left. You can actually sell those tyres to rethreaders as the side walls will probably still be acceptable.
