I just bought a 2005 V70R with 7000 miles. After a long weekend trip, I noticed two things I thought I'd inquire about to see if they are common. One, the Pirelli Rosos seem especially loud at almost all speeds. I've had other cars with 40 & 45 series tires that were nowhere near this loud. Is this common to the car or the tires? They are at 32 lbs all around and show even wear. <p>Also, in either Comfort and Sport mode, the car really jumps out of line when you hit an bump in the road, like a big expansion joint, a crack in the pavement, etc. Mostly if just one side of the car hits something. Reminds me of an old solid-axle car. <p>

Re: new V70R owner has two questions - tire noise and suspension (JHB)

Congrats, Welcome to Swedespeed and, in every sense of the phrase, Welcome to R ownership.<p>In short, the PZeros are partly to blame for both the noise and the hop you're experiencing. They wear extremely quickly (as do all ultra high performance - summer only tires). If you replace them with a better set of tires (e.g., Michelin Pilot Sport PS2s, Goodyear Eagle F1s, etc.) the noise will probably go away.<p>The hop you're referring to is also a notorious side effect of the 4C system (and probably the PZeros). If you research "4C" you'll find a plethora of information on the benefits and complaints many have about the system. The best solution to the hop is a set of TME springs (or Evolve if you want a lower stance) and a rear sway bar. The new springs and rear bar combination allow the 4C to do what it was designed to do.<p>-Eric

Re: new V70R owner has two questions - tire noise and suspension (JHB)

The P2 chassis (which includes your V70R) seems to bring out the worst in tire noise. It really is road surface dependent and when on the right surface you will ask yourself, why was I concerned about tire noise. Unfortunately the other extreme is true on other surfaces where you can not hear yourself think! <p> I do think the OEM tires are quieter toward the end of their life, (10K to 25K depending on driving style), and they definitely handle better at the end of their life, except in the wet of course.<p>There are few tire selections available for the V70R if you want to maintain the door sticker-ed GVW. It requires a 97 rated tire. Many have gone with a lesser rated tire on their V70R. Depends on your comfort level, typical cargo and passenger loads, etc.<p>As stated the P2 chassis, with, or without 4C, (all Rs have it) do have rear suspension side hop issues. Tires help but are not a cure all.<p>Any change in the suspension components, such as springs, sway bars etc. provide the dealer a "get out of warranty free card". Check some of the threads on this board and you will see that it is a card that is readily played, and failed components on the 4C system are costly. Most do feel that the change in components improves upon 4C at an overall cost of around $2K, and loss of warranty. Ground clearance is already an issue on a loaded V70R so you may want to consider it as well before changing any springs that impact ground clearance. (They all do to some extent). None of the suspension changes help reduce the large turning radius.

Re: new V70R owner has two questions - tire noise and suspension (rogersampson)

Look at mine in my signature, ("WEBPAGE" below)<br>This is with TME springs 1/2"+ drop, MUCH better handling along with a rear sway bar and Michelin PS ALL seasons (18's).<br>Check with your dealer, some are mod friendly and some are not. It varies from dealer to dealer with NO uniform policy from Volvo <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/frown.gif" BORDER="0">

Re: new V70R owner has two questions - tire noise and suspension (JHB)

What took you all so long to reply? Good feedback - thanks. These forums are very helpful. <p>The hop I can deal with now that I know is common. The tire noise is very fatiguing, however. I may talk to Tire Rack. <p>I will talk to the dealer about the bushings when I'm in next. I had the iPod adapter installed and there was some alternator noise that they are solving (I see it is not uncommon if you have Sirius and Nav too). FYI, regrounding everything seems to have helped. <p>Other than that, an interesting and fun car. <p>

Re: new V70R owner has two questions - tire noise and suspension (sk11vengeance)

No offense, but as bad as they can be (unpaved and tertiary roads aside, too), people in the south don't know 'horrible roads'. NC may get cold but, try living with asphalt that goes through 3 months of 90-100F degree weather and 3 months of 0-20F degree weather. Any idea what those shifts in temperature coupled with tens of feet of ice and snow, salt, and heavy snow removal equipment can do to an asphalt road? Asphalt and sharp equipment that scrape endlessly at its surface don't get along very well. Add heavy traffic (trucks) to the mix and all of a sudden you're tramelling from Cherry Hill, NJ to Bangor, ME dodging pot holes the size of 'dubs all the way.<p>-Eric

Re: new V70R owner has two questions - tire noise and suspension (Sue Esponte)

Great description. That's exactly how I feel. I've got one section of road here about 10 miles long that I can use advanced on. By next year it'll be sport, with lots of pothole dodging, and in 2 years it'll be comfort or a bent rim.<p>JHB - welcome to the forum!<p>My sidehop got a lot better when I put 17" Blizzacks on in the winter. The GY Eagle F1's that I run in the summer are better than the stock pirelli's, but not perfect.

I'm generally pleased with the performance (although haven't tried them in cold weather yet) and you can't beat the price, but the road noise I'm experiencing with them is considerably worse than what I got with the OEM Pirellis near the end of their tread life. It's so loud, in fact, that I'm wondering if it's something more than tires, although previous posts seem to indicate tire noise is yet another little quirk of (especially) the V70Rs.

Re: new V70R owner has two questions - tire noise and suspension (Lead Foot 60)

I'm not justifying the exhorbitant prices of some tires, but generally speaking...you get what you pay for. Falkens, Kumhos, Hankooks, etc. all seem to be goodt tires "for the price" but that "for the price" qualifier seems to be included in every review I've found on them.<p>-Eric

Re: new V70R owner has two questions - tire noise and suspension (Sue Esponte)

The Goodyear F1 D3-G3 got the Consumer Reports "Best Buy" rating for high performance summer tires. No personal experience with them but I love my Pilot Sport All Seasons for year-round use up here in the Pathetic Northwet.<p>They are fairly quiet, have a good treadwear rating and are exceptional in wet and light snow. I'm at 5/32'nds on them and they have been good reliable tires and I'll probably get another set. They are loud on concrete but quieter than the Pirellis on concrete and asphalt.

Re: new V70R owner has two questions - tire noise and suspension (StaggRLee)

Discount Tires has the best pricing, and F1s are great. I now have 2,500 miles on them.<br> <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> <br><A HREF="http://forums.swedespeed.com/zerothread?id=55428" TARGET="_blank">http://forums.swedespeed.com/zerothread?id=55428</A>

Re: new V70R owner has two questions - tire noise and suspension (TexasV70R)

I've heard great things about the F1s. I'm torn whether I want to give them a try over the PS2s or even the Yoko Advans when I replace these awful PZeros.<p>-Eric

Re: new V70R owner has two questions - tire noise and suspension (Sue Esponte)

My Pirelli's were extremely loud when I bought the car with 12k miles on it. At that point, the fronts were nearly gone which made for a horrible ride as well. Im sportin a set of Khumo Escta's and love em. As far as the side hop, I'd say the quick and best fix is a set of springs <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0">
