TMPS is like a two sided sword, it's great that I know a tire is running low on pressure but it sucks to know I got a nail in it.
Has anyone tried to patch a run flat tire? From my research, run-flats have a stiffen side wall that maintains vehicle stability in low pressure situations. If that's the case, I see no reason why I cant just put a butt plug into so long as the side walls aren't compromised. Can anyone comment?
Secondly regarding replacing a single tire on AWD SUV's - I understand it to be a bad idea. I want to know what depth difference between tyres before I know for sure I need to swap all four. New tyres I'm guessing have 11/32 of tread? My SUV has 8k on the clock, I'm guessing it's down 2/32? If that's the case would you guys recommend changing all four?
Thanks in advance.
