Bart,
The consequences are increased fuel consumption/ slower speed. Your engine will be screaming its head off and the vehicle will not be travelling at the speed you speedo shows. My Troopie came with 10R15s (31 inch), with testing along side my Wifes car and a
GPS the Troopies speedo was on average out by 10%, being not in my favour (as I said above). I replaced the 10R15s with some BFGs 33 x 12.5 inch, this rectified the situation.
Test it for yourself, take readings (speedo/engine revs) running on the 7.50R16 and then do the same on the 30/9.50R15. To do this on the bitumen you only need to change the rear wheels - DONT ENGAGE 4WD whilst the vehicle is configured like this.
The Troopies wallow a bit like a buffalo, but then you rethink you driving habits and drive accordingly. It took me about 3 months to become comfortable with mine, now its second nature.
