The front tyres on the CRV are likely to need done soon but the wife had to have a rear pumped up today to get home from work.
We will see if it remains inflated but I suspect the rubbish rural roads have taken their toll and it will be a puncture.
I have only had 2 4x4s, one had proper hard core Kumho knobblies on it, the CRV has 4 Bridgestone Duellers.
I have no idea how long these things last miles wise or whether another tyre would be cheaper or more economical etc etc.
We do not use it off road although we did drive out of some pretty squishy mud week before last
