Our partner, bettertyres.co.nz has recently conducted an in depth investigation into the damage caused to Runflats and Ultra Low Profile tyres while being fitted in tyre shops and the findings are blindingly obvious. http://bettertyres.co.nz/?p=599 Make sure your runflat and ultra low profile tyres are fitted with leverless tyre changing technology or you will face the high probability of damage to your alloy rims and tyres.
Conventional, lever based tyre changers were designed for traditional tyres meaning tyres with reasonably soft tyre walls and profiles of 50 and up. But todays tyre retailers are faced with tyre sidewalls that are like concrete and ultra low profiles as low as 25 and also up to 24 inch tyres and rims that are quite huge and very heavy. Lever based tyre changing technology just cannot cope with these challenges. Sure, tyre shops can and do fit runflats etc on conventional machines, but your tyres and rims will almost certainly get damaged. and beware, the damage is on the bead of the tyre and is therefore concealed when the tyre is mounted on the rim.
Leverless tyre changer technology was especially devised to cope with modern tyres; they enable even the most rigid, ultra low profile tyres to be fitted without damage or stress to either the tyre, rim or operator! Going Leverless requires a very big investment, but it is a small price to pay for retailers wanting to give the safest and best possible service to their customers.
