replacement tires, run-flats vs non-run-flats

May 09, 2008 3 Replies

My 2006 GS300 is equipped with run-flat tires. Once you have a flat, the manual suggests replacing all four tires. I am approaching



40,000 without a flat, lucky me, but I don't think I'll be as lucky much longer. I plan to change my tires very soon, but would like to switch to regular radials, not run flats. Anyone had any experience switching from run-flats to non-run-flat radials?

PS: I do not want to change rims to accommodate non-run-flats.


everything I've heard says to stay away from the run flats __________________________________________ Never argue with an idiot. They'll drag you down to their level and beat you with experience.

You may be able to find run-flat support for regular pneumatic tires. I think it was in UK news. Run flat tires allows the manufacturer to remove the spare tire, therefore saving some weight (increase MPG by a fraction). It also helps maintain some directional control when you have a higher speed blowout.

The Federal Motor Vehicle Safety Standard may require manufacturer to provide a pneumatic spare, but does the own need to drive around with a spare? Will a tire shop install a non-spec tire? etc etc
