If you're wanting to save money don't buy new wheels, the improved economy would be microscopic if at all.Originally posted by saint70 View Post -
I still have 17" and i am due to change...so i am.thinking berween 17 and 18"....2014 Passat Wagon, TDI, blue-motion technology, ComfortPower front seats, Adaptive Damping Control, Premium Sound System, Power Tailgate, Sports packComment

The change in fuel economy (better or worse) would depend on the weight and width of the wheel and also the weight, width & tread pattern of the tyre.Originally posted by saint70 View Post
Generally, there is more weight in an 18" combo than a 17" combo & the mass of inertia is moved slightly outwards - both of these will adversely affect fuel economy.
If you spend the coin & buy lightweight 18" rims then you might save a little bit of fuel but not much.carandimage The place where Off-Topic is On-Topic

Generally yes but it depends on the tyre construction & the pressure you are runningOriginally posted by saint70 View PostSo, i assume 18" is less confort as well...am i right? Otherwise, i am going again for 17 pilot sportcarandimage The place where Off-Topic is On-Topic

Check out the price of 18" vs 17" tyres. Even with light weight rims I doubt improved fuel economy would ever recoup the additional cost of the tyres.Former owner of MY12 GTD with DSGComment

I wasn't talking improved fuel economy - simply trying to stay about the same.Originally posted by ParaBul View Post
For improved economy I'd drop back to lightweight 16s with 205 Eco tyres.carandimage The place where Off-Topic is On-Topic

Exactly. What determines consumption is how much mass you are trying to move at what speed and how you accelerate to that speed. The change in wheel size might reduce engine speed, however you will be squirting more fuel into the engine to get it to drive at the same speed or accelerate at the same rate.Originally posted by Ryeman View Post--

A change of wheel diameter will not affect gearing. A change of tyre diameter will.Originally posted by wai View Postcarandimage The place where Off-Topic is On-Topic
