low roll resistance tyres

[jimbomort]

Well we eventually went with Conti Contact 5's, I had meant to buy Michelins, but turned up only to find hardly anyone in the country had, so was looking like the continentals or nothing. Not bad tyres, pretty smooth and quiet, haven't pushed enough to comment o nthe handling but good enough. Better on fuel? If they are not overly convinced. Indeed our fuel economy on the trip was nothing to Rave about. By MFD 7.8 to Sydney and 7.8 back from Tamworth, but well up into the high 8's on some other sections (albeit doing more 110-120 work and hills), so never got close to high 6's low 7's, which I have done plenty of times in the past. WE were fully loaded including 3 bikes on a bike rack and a roof pod, but sure I have done some trips before like that with substantially better economy. I can comment for certain when I have done some med local trips without all the load, but at this stage would not recommend the conti contact 5's as low roll tyres, but fine otherwise.

Other than that Tig did great on our 4000 kay trip (down to Vic and back) and with stage 1 overtaking is a breeze even fully loaded.

Hmmmm, this might explain why my fuel economy is way over you guys previously. I've got Continental's on mine. But just about to get some new tyres, so interested to hear what tyres you had previously when getting the low fuel economy. Also, how many k's did you get out of your old tyres?

My conti's have been quite durable. Just under 50,000kms out of them and could have got more (at least another 5000-7000 kms I reckon) if I did a wheel alignment earlier (wearing on the inside means I have to change them earlier unfortunately).

Don my previous tyres were Hancocks, I didn't mind them but they were pretty had it wear wise by 40k, so wasn't that impressed with the wear.

Driving style, use of air con and speed make a big difference to fuel economy too. For example I consistently get 10-15% better economy than my Mrs in the same car.

How much over are you?

I must say in the end I wish I'd just said what the hell and gone for the larger diam pirelli scorpions like I originally planned and not worried about doing it officially. Would have been a risk, but I think a low one and better to have done it now, rather than in a few years when I get into the annual roadworthy check.

Anyway sa la vie

I'm pretty consistently getting 10's city driving and 8-9's highway driving but that's sitting on 105-115km/hr on the speedo. I can't say I've ever got as low as the 7's that you and Team V are reporting??

Perhaps it's a tradeoff with tyres on tyre wear versus rolling resistance?

I've got the Continental Cross Contacts.

Tyre pressure, speed and air con are the 3 biggest ones that will affect it.



Make sure your tyres are pumped up 38psi for highway driving should be fine.

Driving at 80km/h in 6th net's the best fuel economy, up to 100 will still be good but anyhting over that starts to drink abit.
Having said that, i got 8l/100km displayed on my trip out to Roma where we were doing arond 110km/h.

Air con will consistently reduce fuel economy by at least 1L/100km if not 2.

Roof rack (cross bars) are also a known fuel economy eater.



Note that i only get 7's on highway trips when no air con is used.
