Friends,

I have a 2004 Prius with the Goodyear Integrity tires on the factory wheel and would like to know if anyone's tried 'plus' sizing for custom wheels.
The Integrities lose traction upon a right turn acceleration and my VSC kicks in, momentarily stalling the car.

Since Costco carries the Michelin Hydroedge I am particularly interested if anyone matched perhaps a 16x7 wheel with Michelin or other easily obtainable tires.

If I do stay with the factory wheel/tire size, what tires would you recommend for the Southern California area.



Thank you.

mike

Consumer's Reports did a study on +1 and +2 wheel oversizing. There were some pros, but quite a few cons. Their recommendation is if you insist on doing it, go no further than +1.

I think low profile tires look cool, but the cons have me go against it. I am glad I wasn't forced into the Pirelli setup often packaged 'round here.

My european Prius came with Michelin Pilot Primacy 195/65 R16. Does anyone uses this tyre size? The recommended pressure in John's page applies for these tyres as well?

Spacejazz, your Prius uses 195/55 R16 on 16x6" wheels.

As they are a bit wider, you should lower the pressure 0.1-0.2 bar from those indications. I think it won't be a good idea to exceed 2.6/2.4 or 2.7/2.5....

check the sidewall of the tires for the max. cold inflation pressure. Do not exceed the rating that is on the sidewall of the tires.

(The 2004+ OEM Goodyear Integrity tires in the US have a max. cold inflation pressure of 44psi...)
