Is there an issue with upgrading the stock 15" wheels on a Cross Country to 17"? I'm concerned that there may be an impact on the AWD drivetrain.

On IPD - Try calling them. *If* they were ignoring you, it'd be tough to do so on the phone.
On tire size, if you have a good relationship with your dealer or a friend with an R or a C70, you could always ask them if they'd let you swap the 17s on the car so that you can take it for a test drive.

Yes there are some issues. Let's not talk about how the Volvo engineers carefully tuned the suspension components to match the "stock" tire size...everybody knows that you can't just change one thing--but you already know that.
And let's skip over the bit where almost every tire built leaves the factory in almost any shape *but* round; that the unlikelyhood of having even two tires of the same size and shape, let alone a matched set of four, almost guarentees that your transmission is working overtime trying to match wheelspeed from the moment it left the factory in Belgium (or is it Mexico, now that Ford owns them??)...that is to say...don't worry about your tranny...just be happy the car isn't crabbing sidways down the interstate...something you can only see from behind...and try not to think too much about the pull to the right, no matter how may times you check the tire pressures and alignment...every V70 AWD for the American market does that...they are built for conservatives...the lefties don't own cars.
Let's talk about my issue:
Let's talk about tire load ratings. If you ask Volvo or check a site like Tire Rack they will tell you to go 215/45/17 for a 17" wheel "upgrade". But before you press play, click the "specs" button for your tire and look at the data. Check out the diameter and circumference and "load rating" of your stock tire and see if your 215/45/17 tire choice is the same. No? Well then if it's just a little bit different then your speedo/odo will be just a little bit wronger than it was. No worries. Who really cares to know exactly how fast they are going, or how far, or for how long? The only thing that really matters is, does that woman talking on the cell phone while she does her maskcarra in the cocked rearview of that SUV bearing down on you...does she see that the light is red?
... i digress...
But what about the load rating? For my situation, the load rating for the 215/45/17s was SEVERAL HUNDRED POUNDS LESS !!! than the stock tires. And it was less for every brand of tire made in the 215 size! I bought a wagon because I occasionally load it to capacity, with family, and drive several hundreds of miles in dense traffic at idiotic speeds. Some call this "vacation", but if you have children, you call this "a trip". You can't have a vacation when you have children...but you already know this.
But that's ok, because what I wanted to do was go 225/45/17, which matched the stock tire diameter/circumference almost exactly, *AND* had the same load rating: BUT WOULD IT RUB???? because it was getting pretty wide...(and why doesn't Volvo recommend this size??!!).
you see that's what IPD put on their '98 Cross Country (see: "http://www.ipdusa.com/project_cars_xcr.aspx"), so I emailed them twice asking if the tires fit ok, and they wouldn't say. they just refused to answer...which makes me very suspicious. they aren't talking...must be a lawyer involved somehow...very suspicious indeed.
so I asked around all the Volvo websites I could find, and mostly was ignored, or received a description of a completely different car--you know how sick people who hang around these places can be...most aren't taking their meds, and the rest don't yet know they need them.
some people say "no way--they will rub, fool", and even "the 215/45/17s rub on my 850 wagon" (same car as the V70, but costs less), while others say, "what the hell--who cares if the tires rub a little?" (the horror!)
so...I'm waiting for you to try it. let me know will ya? I have a nice set of 17x7.5" Comet rims sitting new-in-box. I'm just waiting for someone somewhere to tell me it's ok to mount the 225/45/17 tires. My Volvo dealer ain't talkin', and God forbid Volvo America ever did anything to help it's customers...just try asking them a technical question--"....(run away! run away!)...they ain't talkin', and IPD ain't talkin'.
Somebody's gotta come clean on this...
some brave soul, with money to burn (rubber that is) is going to try it.
i think it should be you!
be my hero! and if you live to tell the tale, would you please post it here, for the rest of us?
ps. what ever happened to the guy who bought IPD's XC with the wrong sized tires???
