NO, It's not just you.
Back in the day, Conti made a great Motercycle tire.It's claim to fame was that the tire "wore" like iron.Oh sure, There was a noticable lack of traction with them, but what the hell - They wear like iron.Basically, what that means is, we 'll have a tougher time shredding our rubber with these harder composition tires.

Yes I too notice the hard highway sound.Very reminicence of the "old" snow tires.I'll just wear these out this season and replace them in the Spring along with wheel mods.

Life is so boring and predictable with regard to this topic.

Ive got 9000 miles on my self sealer Conti's and I haven't noticed and increased road noise. But over the past 1000 miles I have noticed a significant increase in tire squeal when making turns into driveways, or driving on/off freeway on-ramps. I am not driving any harder, but the squeal has really gotten loud.

Joey, Don't worry about it,like I said CONTI'S had ( and still do in my opinion) a reputation for wearing like iron but having an inherent lack of traction. The noise you hear is simply due to the composition rubber " hardening" and becoming basically smooth without becoming bald. Let's just call it an inherent design flaw for those of us who might have expected more from D/C.
I remember back in '87 when buying a new car (Merc.),as I started to sign the agrement I put the pen down and said " wait a minute, what tires does it have on it.They had Firestones which at that time wore out fast.I had noticed several others with " Tiger Paws" on the same model.After checking them, I said that the tires were a deal breaker, but if they simply switched them we were good to go. Next day I drove away with what I wanted. Boy how times have changed ! Talk about having a captive audience.

JUNK is an undersyatement. As I stated earlier, at best, Conti's were basically designed as a Motercycle tire !! :fing26:

Took mine off for the winter

I took my 18" conti run flats off and replaced them with 20" F1 super car goodyears. Talk about a grip difference, and no road noise

(Of course I'll have to replace them every 15K miles or so, but what the hell

Ill run the conti's in the winter (I'm in NY and this is my daily driver)

Conti Seal Road noise

I hear that too even at very low speed. I really, really hate it. I sure hope that it is the tire not DC suspension design quality.

That is why i have been thinking to buy new tires (not yet though), but would them be 18" or 20" + new wheels ?!
With this car (300C) i would really like quiet tires, good at dry and wet surface. But all other like hard cornering abilites are not so necessary.

Conti Update

We just got a look @ the new (2006) Caddy DTS That we will be using for our Livery Service ( to the tune of 20 each month that we turn over @ 32,000 miles. They also are coming standard with the Conti Self Sealers !!

So it's not just D/C but GM at least as well.Oh well, I figure that they know something we don't know,; or were they given an offer they couldn't refuse?? :fing26: :eek:uch: :fing26:

Probably under the table to some guy in purchasing. But enough said about the suppliers of the Auto industry.

I just replaced my tires this past Tuesday with 235/60/18 Michelins. In two words I am "Very Pleased"!!! I got them from Discount Tire and they even pro rated the Continentals out at 100% and that amount was applied toward the new Michelins. That made me even happier. :)

Mine are getting replaced in 4 days, I hope it solves the steering kick I get on bumps.
It probably will solve your" steering kick" problem. Hard composition rubber tends to bounce causing steerage to wander to the line of least resistance.

Today I got so pissed with the noise of my Conti's I drove into Town Fair Tire and ordered a set of 20" wheels with Toyo's. First idea was to put them on the AWD asluminum rims, but they mouted a tire on a chrome wheel, and it was no question. The look is spectacular.

Pictures to follow soon.

Gang,

I've had to made two trips to the dealer to have my computer reset for this size tire. (there is no setting in our ECM to cover this size) After a little research the dealers Tech and I discovered that the SRT-8 rear tire and this tire is the almost the same size. When you go out to the Interstate and time the car between mile posts, it comes out correctly. The rear size for the SRT-8 is 255/45/20 and that's the size you will want to set your ECM to.

I too, recently noticed the extra tire noise from the self-seal Conti's. It is irrating thet such a nice piece of engineering comes with such poor tires! Also the winter traction, if you call it that, was very poor. I don't even have 5,000 miles on the tires and can't wait until they wear out, which according to others won't be too long! I am a Michelin fan but all Micheliens aren't created equal. Other than BF Goodrich, what other 18" tires (tire models) including Michelin do people have installed?

I have posted if a couple of recent tire threads I put on the Goodyear ComforTread 225/60-18, very pleased with the ride, lack of jolts over bumps, noise level, handling etc. They are said to have great rain and snow traction and got outstanding reviews in the Tire Rack survey (TR does not list our size), I got mine from a GY retailer for $137. You are right about Michelin, some are good some are not and all are expensive.

I purchased mine at 8,200 miles at the end of February, and the Conti-Seal tires seemed fine then but at 14,000 I noticed a vibration in the front end at 68-73 mph.
I was told by the dealership at 15,000 miles that they needed to be replaced!
Continental will drop the price to $102.70 but they still won't be under warranty as
they revert back to OE.
I'm not sure what other tires would work on a 300C and they say to stay with 225/60r18....
Any suggestions?
