Most part worn tyres are sourced from Germany I beleive, due to the law being that tyres have to be changed on the same axle together (iirc)... I also beleive that the 5mm minimum is UK spec for selling part worn tyres...
Personally, I would much rather use a brand name part worn over a budget ditch finder...
Even though they may have been stored next to a radiator and are rock hard with absolutely no grip?
Yep!
Personally I would rather choose not to do something I cant afford than to cut corners (especially with regards to safety). Others may think differently.
So what your saying is, if you can't afford top quality tyres, you don't by any? Which for some means don't go to work or pay the mortgage either, if the cars not available, as it has no tyres on it...?
Always buy the best quality tyre for available budget, obviously. Others with less healthy waletts will think differantly for sure.
IME an old tyre will loose performance evenly between wet and dry grip.
Budget tyres can work deceptively well in the dry and be bloody dangerous in even mildly damp conditions. The difference in performance between wet and dry conditions is startling IMO.
Although others may have different experiences clearly.
Times are hard currently, as we all know. Part worns have their place, like it or not. Not to mention the complete waste if they're not used.
