It was also serviced at the dealer under the 3-year free maintenance deal then standard at the time of purchase. It's got less than 40 000 mi on the odo (64 000 km). It's got great highway fuel economy--30 to 34 mpgUS (equivalent to 36 to 41 mpgUK and 7.8 to 6.9 L/100km). But this good fuel efficiency comes from low ground clearance and was apparently partly due to the OE tires being of low rolling resistance. The first highway trip I took after I replaced the OE tires I got only 29 mpgUS (35 mpgUK). I have scraped bottom on some rough roads I have gone on. Your XC70 has considerably higher ground clearance than a standard V70 and AWD too. I assume it has the turbocharged 5-cyl rated at about 210 hp. So it will not match the fuel efficiency of a standard V70, but is a more rugged vehicle. In the late 1960s I lived in Fiji for two years, worked for Australians, and got plenty of time in Australian cars of the day. A 21st century Volvo is a far cry from a 1960s vintage Australian or US car.

Replying to: jim314 (Mar 25, 2009 7:22 am) You'd worked in Fiji in the 60's? Wow I was only an infant then! I am from Perth and now live in Sydney after working through Asia & the U.S. for FX in the 1990's and most recently spent 15 months in India. Now you hardly see our type of Volvos in India! My first car when I got my licence was a 1966 HD Holden Wagon if you remember seeing them in Fiji or maybe not. It was a rust bucket, used a litre of engine oil every week but goes well! Oh and it was a 3 speed manual on the steering wheel. The old 3 on the tree! Them were the good old days where the headlight dip switch was on the floor! And none of these high tech computers we now have in our cars.

Replying to: xcv70sydney (Mar 26, 2009 5:01 am) Of course, yours may have larger wheels--16", 17" or 18"--with lower profile and wider tires. What is the size of the tires on the vehicle right now? See the large writing on the sidewall. According to TireRack these are the specified sizes for your car: 15 inch wheels: 205/65-15 (OD at tread 25.5 inch) 16 inch wheels: 215/55-16 (OD at tread 25.3 inch) 17 inch wheels: 215/50-17 (OD at tread 25.5 inch) 18 inch wheels: 225/40-18 (OD at tread 25.1 inch) Even if your car came from the factory with Pirelli tires that doesn't mean those would be the best for the car, and almost certainly wouldn't be the best value. Check out the other brands, especially see the Kumho offerings. My 2004 base model V70 came with 195/65-15 (25.0 inch dia at tread) and I stayed with that size when I replaced the OE tires. Some people mount wider and lower profile tires than specified, but this can lead to rubbing of the tires on the wheel wells and suspension especially as the vehicle ages and the suspension loosens up. For example, suppose you have 15" wheels, then some people might mount 225/60-15 tires, but often this leads to headaches. These are 20 mm wider than the OE, but since they are lower profile 60 series then the diameter at the tread is about the same as the OE 65 series tires. This means that the calibration of the odometer and speedometer doesn't have to be fiddled with to remain accurate. But these tires could rub on suspension components or the wheel wells. Dia in inches of 205/65-15 = (205mm/25.4mm/in)(0.65)(2) + 15 in = 25.5 inch Dia in inches of 225/60-15 = (225/25.4)(0.60)(2) + 15 = 25.6 inch

Replying to: jim314 (Mar 26, 2009 8:25 am) (205/25.4)(0.60)(2) + 16 = 25.7. I wonder what Volvo says is the specified size for 16" wheels on an XC70? IMO there is no point in having low profile tires on an SUV. So SUV should not have tires lower profile than 65 series or at the lowest 60 series. The base tire on the 2007 XC90 is 235/65-17, and replacement tires are a lot cheaper than those on the optional 18" wheels.

Replying to: xcv70sydney (Mar 27, 2009 2:00 am) http://www.volvoforums.org.uk/showthread.php?t=41689 http://www.volvoforums.org.uk/showthread.php?p=271649#post271649 The 215/65-16 tires have an outside diameter of 27.0 inches and may be a little larger than exact spec by about 1.1 %. You'd have to check with Volvo. But this difference may have no problems for you. If it is over spec, the odo and speedo would both read falsely low. A trip where the odo shows 100 mi would actually be 101.1 mi. If your speedo shows 70 mph then you are actual speed would be 70.8 mph.

Replying to: jim314 (Mar 27, 2009 3:56 am) I see that the specified base tyre for the 2009 XC70 is 215/65-16, which is what you have on your 2000. Since you are not the original owner you might just check with a Volvo dealer to see if this size was the OE spec in 2000. A tire which is 27.0 inch diameter at the tread is 5.9% larger than one which is 25.5 inch diameter. If they tell you that the specified tyres in Australia are what you have then you can assume that your speedo/odo are reading right. But if the specified size was different from that, then the previous owner could have had the speedo/odo recalibrated to read correctly with the larger tyres. So you should check the odo over one of those calibrated distances. Be sure to use the trip odo since it measures to the nearest 0.1 mile. The speedo counts the turns of the wheels in a given time and converts this to speed by mult by the circumference, and circumference is pi times diameter at tread. Therefore, if the speedo is calibrated to read true speed with 25.5 in OD tires, but you are using 27.0 in OD tires, then the true speed will be 5.9% higher than the indicated speed. For example, if your speedo reads 70 mph, you are really travelling 74 mph. And if your odometer reading is 100.0 mi for a trip, then you actually went 105.9 mi.
