Unusual car tyre wear issue.

[Bonefish Blues]

Find a motor engineer to do a report to present to Suzuki if they don't listen get trading standards involved.
If no luck get him to devise a solution which you can sell to other owners!🤣🤣

It'll be within tolerances, and money will be wasted to no good result IMHO - hell, engines using 1ltr of oil in 1000 miles are within tolerances these days!
