tyre wear

[Dickylew]

Run my B-MAX about 4 times now just runnung around the local tarmac carpark, using a mild modified 17t motor so nothing too hot.

For some reason the front tyres have worn very badly and are virtualy as bald as my head.

The car handles ok and slides at the rear slightly when cornering but there is no wear on the rear tyres.

Built standard as kit instructions, could it be the diffs or clutch not adjusted properly?

New to this so could someone help on this and how should the diffs be set loose/tight etc.

Could someone also recomend on what replacement tyres to buy?

Regards.
