We have just completed 10,000km through rough tracks in an around Central Australia towing a 1500kg camper trailer. We had plenty of full up and down travel of the suspension and I can confirm what Gordon (GOE) now states on his web site, that the tyres just contact the chassis behind the front wheels when going backwards only and that the rear tyres just contact a seam in the wheel arch. I didn't know about the latter till I got back and there has been some rubbing on the plastic liner in the rear, which now has a hole at the offending location. No damage to anything else or the tyres so the rubbing is very minor and much less than what I get on my GQ Patrol with 33's.
Raising or lowering of the suspension has no effect on the rubbing of the tyres and in fact the front rubs with the wheels nearly straight while reversing on a flat bitumen road. The only way you know is because of the noise of the tread rubbing past the chassis extension immediately behind the front wheels. This is the location that was worrying the tyre fitters also. When in forwards gears, there is a significant gap at this point and no rubbing at all in any sort of extreme conditions, of which my car has been in plenty.
The bigger tyres mean that my speedo, which was optimistic, is now exact at all speeds. However, the odo, which was exact with factory tyres, is now reading lower than it should due to the larger radius tyres.
