Ok so I am a newby with a new 1997 90 station wagon. tyres fitted at the mo are 112/110 N 7.500 R16 on boost alloys. With 235/85 r16 on the spare. I need new tyres on the front, can I have 235/85/16 on the front and keep the 112/110 7.50 on the rear or do I have to change all four. can...

Hi new here and just purchased a Defender 90 tdi county sw 1997. The service history has been lost. Ive tried the obvious things with no luck. Anyone any ideas or maybe someone here works at a main dealership and can help me out for a drink. Thanks Steve
