My left rear tire seems to have a slow leak. I hope it is related to the valve and is easily fixed. If not, what is the current thinking on patches vs. plugs. I don’t like plugs much based on one recent experience when the plugged tire blew dramatically at 45 mph. If the tire can’t be fixed, what is the breaking point between changing one tire and changing all four? I believe it is related to tread depth. Below what level must all four be changed. I have F1 A/S on my V70R. Thanks.<p>Tom<br>

Re: I looks like a slow tire leak - options? (jstro)

i'm a total noob, but i was under the impression that since the AWD is really FWD until it senses wheel slip, you could get away with replacing them in pairs. don't yell at me too much! <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/frown.gif" BORDER="0">

Re: I looks like a slow tire leak - options? (vickisue97b)

Back in early 2004 I replaced a couple of the Pirelli's since I didn't rotate them within 8,000 miles and destroyed the fronts on the Autobahn. I changed all 4 around 20,000 miles. I never had a problem, but I learned to rotate the tires. My driving has changed a little since those days. Tires last a little longer now. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/tongue.gif" BORDER="0">

I went through this recently. I had a puncture (serration) that would only leak a few psi overnight, so fix-a-flat never got to fill it. Because hardly anyone will patch anymore, I had a local shop pull the tire off and I patched it myself and had them re-install the tire. It worked.<br>Else, replace all 4 as you want to keep treads similar, although you have a little more lenience with our AWD system since its variable and not symmetric.

Re: (phuz)

I got three 17" Michelin PS2's that I am not sure what I will do with. Similar problem, I got a bubble on the side of one. I got maybe 6K miles on them. What do you do with the 3 tires?

I have never had a problem with a plugged tire, but there is that chance that is can blow out. Also, once a tire is plugged, it loses its speed rating.

But everyone remember the Pirelli's are crap! And the set I picked up practically brand new with 18" rims for under $800 after repair and repaint are just about worthless as well. Anyone got anymore worthless tires out there? <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/tongue.gif" BORDER="0">

Remember that when replacing less than all four, stick with the same brand/model of tire.

on these new models with the haldex awd you can replace a single tire. <br>the tire must be the same make, model, and size as the others, <br>but the tread depth does not have to be exactly the same... <p>that's the nice thing about the haldex <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> <p>trying to match the pairs is always a good idea <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0"> <p>

if you don't mind using "crap" tires, like the kind used on Ferraris and Lamborghinis (crap cars), you can often find Perrilli P-Zero Rossos in the classifieds on this site for next to nothing.<p>

Check your valve by either dropping a little spittle on it to see if it bubbles. If it does then tighten the valve. If that doesn't work then a can of tire sealant.<br>done.<p>Done.
