you can't balance tyres, but sure get the wheel balance checked do you still have your Ka? if you manage to diagnose your vehicle and need parts we have two branches in Ireland: i could set up discount for you for collection - Unit 8, Adelaide Business Park, Falcon Rd, Belfast BT12 6RD - 9 Prince Regent Road, Castlereagh, Belfast BT5 6QR if you can't get to these places, alternatively i could courier you the parts from Aberdeen if you are deciding to get someone to remove your wheels and check the balance of them, consider the current tread depth. will they required changed in a few month or do they have plenty of beef left? if they are not healthy look at getting new tyres. you would be paying to get your wheels removed, tyres fitted and wheels balanced. So you could cut out paying extra diagnosing time trying to find the cause of the problem, by eliminating the cause of the problem. unfortunately we aren't a stockist of tyres so I couldn't help you there. however go to local business rather than national fast fit centre. ?remember these places have targets to meet and operate upon an irrational level of repairs due to time constraints if you go in with a suspension knock or a symptom that requires investigation, they will not spend time identifying the problem, they will replace entire suspension components at one area and charge the customer accordingly.
