What tired do you have?

 

I have the exact same issues. My 03 str has toyo proxes FZ4's on it and it makes a high pich sound and a ZZZZZZZZZZZZZ as i'm going down the road and a howling at about 1700 rpm. I thought ( and still do)think it is wheel bearings but I took it in and of course theres nothing wrong so i'm going to try electronic balancing. I also tried playing with the air perssure. We'll see what happens. Maybe we just have noisy tires!
let us know what you find rdshirt1

 

Which S type do you have?

I have the R and it's very noisey on highway at 50mph+ I assumed its the tires and part of owning an R but if you have a regular S type you should have less noice.

 

My 1993 XJ40 is very noisy, or at least more so than I would have expected from this level of car. I got it two weeks ago, and my first impression was the same as yours. Louder than any of our other domestic cars, including, a 1989 Buick, 1991 Cherokee, and a 2006 Mustang...

 

My 90 and 95 XJ6's were very quite but my 03 str is very noisy. I had the tires electronically balanced and no difference as far as vibration goes. I get all kinds of different sounds.

 

We'll since we all have different tires and we still have the same noise I'm going to guess it's not the tires but simply a noisy drive train. I don't think it's going to go away!

 

I also was very uncomfortable with my 2003 S-Type road noise. When I bought the car (used) the dealer had just put on new tires - Falken ZIEX ZE-512. Since they were new, I continued to use them, but I was told during a recent service that they were cupping - possibly increasing the noise. So, I went to my neighborhood Walmart Store and ordered four Goodyear Assurance ComforTred ($127.16 each) I was amazed at the difference in the noise level these tires make. My S-Type now rides and drives smooth and QUIET - the way I think it should be. Anyone interested can take a look at these tires at:

Be sure you look at ComforTred - not TripleTred - the ComforTred have 10 rating in both ride comfort and quiet ride. Believe me - there IS a BIG difference in the noise level. I now have a luxury ride, as well as a sport ride. That is what I was looking for. BTW, I also found this worked on my 2000 Lincoln LS. It had Michelin's which were much to noisy. It is now nice and quiet with the GoodYear ComforTread. I recommend them to any of you who are wanting a quieter Jag.

 

Hey, Thanks for the info!

 

Sorry for double post.

 

You're welcome. I am not a Goodyear employee - lol. I just wanted a good smooth quiet ride and looked around quite a bit for a tire which I hoped would meet my criteria. WalMart has these tires at their online site with FREE shipment to a local store, or your local store can order them. Most local WalMarts do not stock them. Their price is lower than the Goodyear Dealer here. Some of my friends think I'm a little crazy for wanting a quiet ride so bad I would switch tires, but why have a Jag if you can't enjoy it the way you think you should.

 

the goodyears are a good idea. i use to work forgoodyear and can say i would put them on a jag if i had one. the european brands like michelin and continental seem to use harder rubber compounds for that sporty feel. if you want to go for a quiter ride, goodyears or maybe bfgoodrich would be the way to go.

 

If you don't drive a jag, what r u doing here than?

 

oh i drive jags, 5 days out of the week. im a jaguar tech. i have complaints about road noise alot.

 

What do you find to be the cause of road noise most of the time, is it mostly the tires or are there other causes?

 

nti06 - glad you're in here -especially since your a Jaguar tech. Your input will carry weight with me, since you have experience with more Jaguars than most people in here. Thanks for your input.

 

I'd be real cautious about having ol' NTi06 here...seems to have good info..but likes to slam our babies as well...

 

I guess I am too new to know all the quirks of the forum - thanks for the heads-up.Maybe we just need tolook atinfoand advice given and make our decision whether toaccept it, no matter who the source is. Anyway, glad the forum is here and people participate. Appreciate your point, racerx82.
