Hi @Mike.. Judging by some of the comments in the thread I bet you wish you never raised the topic in the first place!! Unfortunately the subject of mods within @Carnity is a contentionous one to say the least . That’s why I decided to keep my car as close to stock condition as possible.😉
Anyway, to your question, I had exactly the same issue last weekend with my Toyota land cruiser. Last week I took the plunge and changed my stock 18in rims and 285/60/r18 AT tyres to 285/70/r17 wheels / AT tyres. The new set up results in about a 1” dia increase . I didn’t experience rubbing on the road, but during last weekend’s drives, I did notice that when in deflated condition and when turning as the suspension was extended, I got some slight rubbing on the mud flaps. As @Gaurav says, it’s probably something one can live with, but I don’t like hearing dodgy sounds when driving in the desert so decided to get it corrected this week. In my case, and I am not sure if it can be done for Pajeros, my garage performed a body mount chop. Clearance between tyre and mud flap is now significantly bigger and fingers crossed I won’t have any issues this weekend when I give it a test in the dunes.
As said, I am not sure if the same mod is applicable to Pajeros, but I am sure if you visit a competent garage you will get sound and constructive advice on how to correct the issue.
In the meantime I hope you enjoy your new setup. For me it was definitely worth the investment. My LC cruised up the tall dunes in badayer last weekend when previously it had found it a struggle.
