Dear Motor Talker, a question about the right tyre choice: my Jeep Grand Cherokkee 4.0 ZJ currently has quite low BF Goodrich All Terrain tyres 225/70R16 on it. Other series tyres for my car are probably 215/75R15 100S or 225/75R15 102S. Now my problem: we are in Mongolia with the car and are standing in front of a longer ride, which is why we would like to raise new tyres again. But the above-mentioned large ones are not so easy to get (or so far even ni Only winter tyres in 225/70R16 could be found, but this is because we want to buy summer or all-weather tyres, of course, no option. Says, apart from the question of deviations on the tacho, o.a. something against tyres of the size 225/75R16 (103S) or 235/75R15. Unfortunately, I know too poorly about the topic, in order to answer this question myself, did not become familiar in the forums and expert advice here on the spot is not so clear. e more. Thanks already, Stefan
