Consumer Reports’ blog has just published an update on its ongoing investigation into the run-flat tires equipped on the Toyota Sienna AWD.
Now, at just over 30,000 miles, (30,247 miles to be exact, as shown) we’re impressed with the wear performance of the tires, which are projected to wear out at no less the 54,000 miles—comparable or better than conventional all-season tires.
For those of you just joining us, we purchased a new 2007 Toyota Sienna XLE AWD with the Dunlop SP Sport 4000 Self-Supporting Technology tires (DSST)—run-flat tires. After the road test was completed, we purchased a new set of Dunlop SP Sport 4000 DSST tires for a tread-life evaluation on our Sienna. The evaluation started at the end of March 2007 and now, one year later, the tires still are trucking on.
