Higher profile tyres would help.

Thinking that! standard 14inch rim,s has anyone used 15in with plenty of steer clearance!

My 1994 courier came standard with 15" rims, you could possibly get 16" from a six stud four wheel drive. You really only need to enlarge the rears.

Look here for size comparisons, you should be able to get up to 3 or 4 % increase:
