Does anyone know what Toyota USA has to say about these tires?

Jeff-

Add to that, the uncertainty of where to get Dunlop SP10s...

These tires also came as OEM equipment on my '02 Prius (Canadian). Checking North American web-sites for Dunlop, and tire distributors, I cannot find any references to the SP10. It's as if they don't exist -- except for Toyota. Does this mean that exact replacements can be purchased only through your Toyota dealer? Anyone?

I hope this info is correct. I seem to remember that Dunlop distribution in Canada was taken over by Goodyear. The SP 10's are made in Japan. The easiest way to get replacements may be your Toyota dealer.

sp10

If you want to get the Dunlop SP10, you can get them at tirerack.com for about $46 each. They are a much stronger tire than the crappy Bridgestones, and they are speed rated up over 160 mph. Mine are great. The bridgstones I had wore out after only 18 K, and I am a very careful driver!

Dixie Toyota replaced the two "Worn" Bridgestone at 44Km (less than 30K miles) and charged $116 apiece incl tax. They wouldn't listen to anything else, so if this other tire is used by them, I would be vert curious! Ican't recommend the original Potenzas!

Just as an update to this earlier post, I have been using the SP10 for over 2,000 miles. They are much quieter than the original Bridgestones, they have better grip, and my mpg has actually gone up slightly to 44 from 43. I run them at 44/42 psi front/back.

The specs listed above say that the tires have a speed rating of S, which is 112mph.
