GM has now agreed to replace the Goodyear RSA'* on my 2003 SSEi because they cannot get the tires balanced (12,000km/7000 miles). I have had this issue before with Goodyear as they seem to have trouble making a "round" tire - I have two tires "out of round" which have now been replaced three different times.

In any case, the good news is that for very nominal costs, I can now upgrade all four tires to the new Michelin Pilot Sport A/*. From my read of all the tire sites and customer reviews, this sounds like an outstanding tire for this car.

Does anyone have these tires on their Bonneville?

I just replaced mine this week, they started to seperate after 50,000 miles. I had bad luck with the goodyears too only no compensation. My new tires are Federal ss595, good price I hope they last....

The Pilot Sport A/* are awesome. Took .3 sec. off of my 0-60. :P
If you can get them for "nominal" costs do it. I had to spend over a grand for that privilege.
I'm still trying to find the cornering limits without breaking anything. Did I mention I was VERY happy with my purchase? I researched and researched, read ~400 reviews. No better all season out there IMO. I looked and looked.

I have Michelins...not sure what type, but I love them! Took the vibration out of the car with those and the Hunter balance. The good years were awful. Had two belts let go on them, same thing on my 99 GTP too...love the Michelins tho (even if they were about $800)!

Haywood - thanks for the endorsement of the Pilots. The dealer had to special order them from Vancouver so I won't get them on until next Wed. Your comments are consistent with all of the other reviews I read on the various tire sites.

As these are apparently "directional tires" - are they still supposed to be rotated? My desire is once I get them on and balanced, I would just rather wear them out where they are and not chance any further issues...

I will report further when I get them on...

You should still rotate but only front to back not side to side for directional tires.

Kooky, I'll be in Edmonton Tuesday. Just a layover on my way up to Norman Wells, Northwest Territories. Nonetheless, You've got to rotate those beasties. If you use that lovely torque on occasion and don't rotate them, well... you'll have bald fronts and newish rears. Ditto on the rotation method. (No left to right, just front to back). Ugh, forgot to mention, the A/*'* come with a 6 year "uniformity" warranty. Sure it'* pro-rated, all tires warranties are, but this seems to be the biggest problem with modern tires (out of round and other nasties).
I look forward to hearing if you like them.

Sorry for the off topic here but why would you be going to Norman Wells? Gotta be -20 this time of year?

Gotta install one of our lovely prototype stirling gensets. And I read it was going to be 10f.

My dealer installed the new Michelin Pilots this week - what a difference and for the first time, a smooth ride! I will never have Goodyear'* on my car ever again!

Haywood - what amount of tire pressure are you carrying - when the dealer put them on they had 38 pounds - I dropped them to 32 but would probably like to go to 30?

Thanks
