Earlier today I received an email from a tyresales customer asking if she should install runflat tyres on her Toyota Camray; our customer had heard about runflats and felt that they would save her from the hassle of changing tyres if she ever got a flat tyre. This really is a yeah nah situation.
Sure, fitting runflat tyres to her Toyota Camray would be beneficial if she ever got a puncture, but unfortunately her Camray was never engineered for the fitment of runflats. The Camray’s suspension is not suitably tuned for runflats meaning its suspension could be stressed and unreliable in demanding situations. Of course Runflat tyres are expensive, hard riding and yield lower mileages than conventional tyres; good reasons for avoiding fitting them to vehicles sold new without runflats. Also the lack of a tyre pressure monitoring system means that flat and deflating tyres could go undetected until the tyre concerned is shredded: that is hardly best or safe practice.
Anyone fitting runflat tyres to vehicles sold new with conventional tyres should inform their insurance company about this change from the vehicles original specification. It’s important to remember that no combination of runflat and conventional tyres is wof legal; your vehicle must have either 4 runflats or 4 conventional tyres.
