Low Rolling Resistant Tires?

Low Rolling Resistant Tires?

Low Rolling Resistant Tires?

(OP)
What are some models of low rolling resistant tires that provide good handling, good all weather traction and low road noise for a family car?

RE: Low Rolling Resistant Tires?

Low rolling resistance fits well with low noise, but the other factors will be trade offs. I  have no current info on models, but the harder the rubber, the stiffer the tread is braced, the narrower the tyre, the lighter the tyre, the straighter the tread groves and the higher the tyre pressure, the less the drag.

For  acceleration, the smaller the diameter the less fuel used, but for constant speed, the higher the dia the better.

RE: Low Rolling Resistant Tires?

The Prius Technical yahoo group have some recommendations. You could ask the manufacturers directly, your potential buy is probably enough to get them interested.

RE: Low Rolling Resistant Tires?

Look for tires containing silica.  These will have the best rolling resistance vs traction & cornering performance. In my view, your best option for fuel economy is still air pressure.  The days of 30 psi or less are going away.  Some ride comfort issues, though...

RE: Low Rolling Resistant Tires?

Check the automotive magazines that do test comparisons.  Also, I like this site below with user reviews.  Start with either 'Tire Surveys' by general categories (e.g., High Performance All Season):
http://www.tirerack.com/tires/surveyresults/index.jsp
or 'Tire Reviews' (can start by vehicle model & year): http://www.tirerack.com/tires/reviews/MenuServlet?search=surveyComments

You can sort results by different factors (dry cornering, wet stopping, low noise) & by clicking on an individuaal tire, can get its specs.  From the High Performance All Season group, since I don't drive in ice or snow (& there  was a local shop having a Dunlop sale), 2 years ago I bought Dunlop SP Sport A2 Plus with UTQG 460 AA A & max. inflation pressure 44 psi (higher pressure lowers internal tire friction, good for fuel economy & tire life).
