I have 255/85 r16 maxxis bighorns on my defender 110 with standard alloy 16x7 +33 from memory, rims. They did not rub at the front but did touch and rub the back spring mount after I fitted dislocation cones/longer travel shocks. I then fitted some spacers from a U.k supplier that moved the wheels out 30mm and problem was solved. Before you say it yes I know not 100% legal but they are approved in both u.k and Germany and are a lot cheaper than a new set of wheels. The bighorns i have are now at 35k's and are getting fairly noisy at higway speeds and will need to be replaced in about 10-15k's. One had a strange wobble at 75-85kph but is better now its been rotated to the rear?
The bighorns replaced cooper st's when i first got the defender and are in another world for both grip and ride they are so much better. Most people I have spoken to who have had bfg's and bighorns would take the BFG's again but the cost sometimes means they go the bighorn as they both perform very similarly on and off road just the BFG mt is quieter, actually i think one of roothy's mags did a comparison of the maxxis,bfg, cooper and several other mt/at brands and it came second overall.
