AT's or Muds on 17"s plus

Anybody have any suggestions on AT's or Muds on 17" Rims? I'm currently running Goodyear Wrangler 225/55 R17.

Also anybody know of a metal replacement rear wiper arm for 2000 freelanders? i've bust 2 of the crappy plastic ones in a year, they have both bust at the connection between the arm and the spindle.

Any help will be greatly recieved.

Ive got 225/55r17's on mine and I am yet to find any AT/MT to fit.

Apparently Colway did ones to fit but went bust last year.

Im having to bid on a set of 16's on Ebay, as tyre choice is then an option as plenty of makes do AT's to fit.

Can't really see running off road on lower profile tyres is going to be that successful. Better to a get some 15" hubs with some decent off road tyres and swap to suit.

The wiper arm is a classic, especially if the blade has frozen to the weather seal and then you reverse with the front wipers on. Lovely option an auto read wiper....
