I like the michelin hydro tire with the 90K warranty. However, in the 18" they only make up to P225/55R. Would I get in trouble putting these on. I have a 2004 330RX. Anyone out there know?

its always best to put the recommended size on the vehicle (costco wont put anything but the required size) but your arent far off (OEM is 235 55 18, so you are going a tad bit skinnier and the profile will be a little bit lower too.

worst case it looks stupid

 

I seriously doubt Michelin will honor a 90k warranty for the wrong sized tires on your RX. Notice the load range is inadequate.

Load range 97 1609 lbs. vs. Load range 99 1709 lbs.

So you see this tire is a poor choice and could pose a safety hazard to you and your family. I'd suggest you rethink your tire choice.

 

i agree with the above, lots of people here praise the bridgestone alenza. i plan on these tires once my michelins are toast

 

I have these tires and while they are a nice tire, I certainly wouldn't have to purchase them again. There are other good choices out there also.
