As US Royal makes a very good tire and because you choose to replace Michelins with them, which in your opinion offers a better or more comfortable ride? I'm starting to look at new tires to replace our Michelins & am leaning towards Michelin's Symnetry. Thanks for your reply.

I hade Michelin's Symmetry OEM I replaced them do to the age 5 years. The uniroyal rides like a dream, quiet I was confused on the 38 psi vs ford recommended 32psi no other tire installer recommends this so hence my confusion. Still no light shed on the subject.
 
Have a great day.

I have an odd problem by marsha7

My 2004 CV LX Sport came with Goodyear Eagle LS tires, rode smooth...after 47000 miles, time to replace...
 
Three weeks ago, I bought 4 of the new Goodyear Comfort-Tred Kevlar or Carbon tires, supposed to be Goodyear's best...
 
Did not work for me...smooth as glass 0-40 mph, from 40-65 mph the seat shook like the rear tires were out of balance, and then from 65-80 mph, steering wheel started to shake...
 
Took them back, they rebalanced them (did not see if they were out of balance) and I drove away, same exact problem at the same exact speeds...
 
This morning I exchanged them for Regatta tires, a proven tire that I put on my Sable 3 year ago...drivers seat continues to shake on a smooth road, and the steering wheel shakes above 60 mph...
 
Even with poor tread, the Eagle LS tires ran smooth up to 85 mph, the car ran true, so I do not believe it is wheel alignment, as the car continues to run straight on the hiway...
 
Before I complain to Goodyear about these tires, any thoughts on what this could be???...I hesitate to think 2 sets of defective tires would land on my car, altho I do feel that Murphy and his Law are close friends of mine...

Last fall, I had to replace a Michelin (original equipment) on the front, because of a nail on the edge of the tread near a sidewall, so bought two Bridgestone Turanzas (I refuse to buy Michelin till the French act as if they like us Americans). For years, I used Turanzas on a Mazda Protege and loved them. These new Turanzas, however, had a rhythmic "flap, flap, flap" to them that made me wonder if they had not been balanced properly. Took 'em back and they rebalanced them. No better! Had them rebalanced, at my expense, by the Ford dealership that services my GM. No better! They "flap" worse when cold, and improve as they warm up, but don't completely quit "flapping." Likely a tire composition matter that no rebalancing will solve.
 
At 72,000 miles, I decided to replace the other two Michelins, but with Yokohama Avids (well rated by Consumer Reports). I put the Turanzas on the rear where their "flapping" isn't as noticeable. The Avids are terrific! Quiet, tri-tread pattern for all season handling (not yet run in MI snows, though), and less costly than GoodYear or Michelin.
 
Years, ago, also, we used to balance tires while the rims were mounted on the vehicle. A strobe light measured how they spun while mounted, which took into account any balance problem that resulted from the wheel/tire interaction with the suspension. They don't use that method anymore, but could there be a connection there with yours?
 
Incidentally, I wanted to buy GoodYear, but don't like the looks of the tread pattern on any of their models. I realize "eyeballing" a tread isn't scientific, but since GoodYear's AquaTread, I've been skeptical of those patterns.
 
Good luck solving your dilemma.

Our '94 Town Car has a set of Michelin X tires with 70k on them with a lot of tread left.
 
Our '95 T Bird has a set of Michelin Symetrys with 48K on them with NOT a lot of tread left.
 
Both sets of Michelins have always run smooth and quiet.

I do not own a CV or GM, but have put a set of these tires on my 98 Buick Regal. Yes, they are highly rated and rode smoothly when new. However, they are a disaster for me. I've had them rotated every 5k miles (30k on them total) and will have to get two of them replaced soon as they are vibrating me to death between 45-65. Above 70 it seems to lessen out. I have had them Hunter Road Force balanced and that has not made a difference. No rim troubles, no other suspension problems. Friend told me that some customers are finding that their experiences don't add up to those of what tirerack will tell you

Its not the tires I have a 92 Grand marq with the exact same problem. Bought the car a year ago with 92000 km and replaced the old michelins because of wear and a little shake. New tires did not solve the shake but emphasized it. I had the balancing redone and that solved nothing. I had the drive shaft and front end inspected and nothing was wrong. I realligned the car and nothing changed. I am turning my attention now to the transmission and the uni joint in the rearend in general, because the shaking starts under the seat. I was told that a very expensive Ford designed tranny fluid (maybe the synthetic mentioned in another thread) is used in a lot of the cars to solve "shudders" in the car when changing gears at slow speeds. If that doesn't work I'm at a loss. I wonder if a mod to the handling package suspension might work.

2006 Mercury Grand Marquis Spare Tire by frank06

I bought a 2006 Mercury Grand Marquis LS Ultimate in April 2006. It has the Chrome Wheel option, and Full Size Spare Wheel option which added $695 and $80 respectively to the MSRP. Not only was it a surprise, but also, in my opinion, deceptive marketing, to not include the information that the full size spare would not be on a matching chrome wheel, but also that the spare tire would not match in name and would be a blackwall and not a matching whitewall tire. Also the fact that the factory puts the wheel balancing weights on the outboard side of the wheel instead on the inboard side, especially on a chrome wheel shows a obvious lack of judgement or outright lack of concern for customer satisfaction. One other comment on a lack of reasoning in the marketing area. On the Mercury Grand Marquis, whitewall tires come as standard equipment, but if you order the handling package, they are replaced with blackwall tires instead of the same size and if you had bought the Ford Crown Victoria which does not come with whitewall tires as standard, you would pay $80 for the whitewall tire option. Not only is the customer that wants the handling package paying $695 MSRP for it, but in reality giving back to Mercury the $80 they would charge on their cars to upgrade from blackwall to whitewall tires.
