Gerrymclean Posted February 10, 2023 Share Posted February 10, 2023 Hi All, I have a 2003 3 litre alphard with and I have rad articles which say you much change all the tyres at the same time otherwise it affects the computer system that controls the all wheel drive system.Any thoughts,? Thanks Quote Link to comment Share on other sites More sharing options...
dugii Posted March 20, 2023 Share Posted March 20, 2023 I would be more worried about the transferbox. AWD systems will eat tyres equaly, if you only change one pair you can create a difference in rotation speed between the axels which will have to be compensated by the transfercase this can lead to premature faults etc. As a rule of thumb you should have all 4 tyres changed at the same time, and they should all be the same size etc. Quote Link to comment Share on other sites More sharing options...
Gerrymclean Posted April 2, 2023 Author Share Posted April 2, 2023 Hi I have two perfectly good tyres (1200 miles) and need to change the other 2. Do I throw the good tyres away? Quote Link to comment Share on other sites More sharing options...

Why would you ? Give them away to a 2wd Alphie owner. Keep them in the Community. Perhaps you should declare their size and place them in the For Sale section.
