Forgive me , why go to WIM before tyres ?
Do they need to see the bad, unequal wear to assist with the individual set up for your car ?
Planning a trip soon and I need new tyres all round.
Thanks
Because if the set up is off enough it will ware the brand new tyres as well, and they will forever show that wear.
If fitting new suspension either lowered or replacement it's worth leaving the old tyres on for a month if possible to allow the suspension to settle or sag in. Springs spend their life on the shelf and then find they have to hold up 1700kg of omega. They will take a while to settle to their true ride hight. Wim recommend a full geo check every year iirc due to normal sag anyway.
Should add, if lowering it's also worth attempting the correct settings via methods covered in the guides as best you can.
Once it's all settled in, set up and your happy, then fit new tyres knowing the set up won't wear them unevenly and cause issue such as those pictured, which can easily lead to blow out if not spotted.
Obviously in the op's case he willhave to suffer any wear while driving to Wim.
