-It would help you told us what model ice, and EV the 225/60r17 will be used on. Also, will the vehicles be loaded (i.e. a light truck usually carrying a load in the back, or an EV that regularly has a full passenger load, etc.). Knowing what model and loading is important in selecting a tire that fit those demands, and also helps in selecting an air pressure.
Example: decades ago, when I first had my S-10 Blazer conversion EV, I enjoyed driving it so much that I wanted/needed to reduce the huge losses from my EV being a wasteful/inefficient/heavy/wind-pushing small-SUV (I needed the larger size vehicle for my person larger sized body, but wanted less losses, so I could have more fun, EVgrins, etc.). LRR tires was one of the options I could throw money at to reduce my losses. At the time everyone on the evdl said to contact a friendly Goodyear rep (Bill Egan, now retired) [ http://www.thefreelibrary.com/Americans+Wasting+More+Than+$2+Billion+at+the+Gas+Pumps%3B+Goodyear...-a0114573977 ], and have him give me his recommendations (he was known for helping the EV racers in that way). My point in mentioning him was not that you should contact them, but that he stressed that the amount of weight on the tires was important. He let me understand that some people do not do the math or detail-digging to know what tire is really right for their needs. Once he knew what my vehicle type was, he asked me to weigh my EV at each tire (he was an engineer, so he wanted good data before he gave his recommendation. You may not need to do this, but I will elaborate anyway). I found that I could get a weight reading of each tire by sweet talking my local dump/recycler into letting me use their scales (during less busy times). With each tire weight reading, I called Bill back and he told me which Goodyear tire to buy (that model is now no longer sold), and how much tire pressure to put in. It turned out, since the majority of my pack weight was in the back, I had 44psi in the rear, and 40psi in front. -It is easy enough to do a web search using low rolling resistance tires comparison Some of the items that came up are: http://www.afdc.energy.gov/conserve/fuel_economy_tires_light.html http://www.tirerack.com/tires/tests/TireTestServlet?tireMake=Michelin&tireModel=Energy+Saver+A%2FS&tirePageLocQty= http://tires.tirerack.com/tires/Rolling%20Resistance%20Comparison http://www.arb.ca.gov/cc/hdghg/tires.php http://www.epa.gov/smartway/technology/tires.htm - It would be nice if there was a one-stop shopping list of which-witch-is which, as soon as a list comes out, it is out-of-date. So, a web search will have to do (using the terms 225/60r17 lrr ) http://www.tirerack.com/tires/tires.jsp?tireMake=Michelin&tireModel=Energy+LX4&partnum=26TR7LX4W http://www.tirerack.com/tires/tires.jsp?tireMake=Bridgestone&tireModel=Ecopia+EP422&partnum=26HR7EP422 http://www.tirerack.com/tires/tires.jsp?tireMake=Yokohama&tireModel=AVID+Ascend+(H-+or+V-Speed+Rated)&partnum=26HR7ASC http://www.tirerack.com/tires/tires.jsp?tireMake=Kumho&tireModel=Solus+KL21&partnum=26HR7KL21 http://www.sears.com/goodyear-weatherhandler-fuel-max-p225-60r17-98t-bw-all/p-09588471000P - I found the range improvement as from 5 to 8% better using lrr tires. Was it worth the cost, for me it was. http://www.thedailygreen.com/living-green/blogs/cars-transportation/low-rolling-resistance-tires-461009 http://www.thedailygreen.com/living-green/blogs/cars-transportation/low-rolling-resistance-tires-461009 http://www.bridgestonetire.com/fuel-calculator On the other side of the coin, when I found I was no longer going to push my envelope and be the road-warrior I was in the past, I slapped some low-cost budget tires on my EV. Wow!, my losses went up, I was seeing 5% less range even though I pumped the tire up 10% past its rating (you have to be careful in doing that on cheap tires). So, lrr tires will increase your range, and EVgrin time, and it can also help increase your ice' mpg. -You can shop around for the lowest price, but I would want to know what model tire fits my needs first, then get the best bang-for-your-$ http://www.google.com/search?hl=en&tbm=shop&q=225%2F60r17+Rolling+Resistance&oq=225%2F60r17+Rolling+Resistance&gs_l=products-cc.12...3748.20439.0.21950.3.1.0.2.2.0.266.266.2-1.1.0...0.0...1ac.1.qBfotjjA9_Y#q=225/60r17+Rolling+Resistance&hl=en&tbs=vw:l,p_ord:p&tbm=shop&ei=gCvsUfT9K4m8iwLP6oCwDw&ved=0CD0Quw0oAQ&bav=on.2,or.r_qf.&bvm=bv.49478099,d.cGE&fp=8b1f79e83d2a6539&biw=1024&bih=616 Since tire brands come and go, searching at the evdl archives as which lrr brand to choose may not work out, as lrr tires are a moving target. You need to know which lrr tires are best, today. I ask others more knowledgeable on this to give corrections/comments. {brucedp.150m.com} - On Sun, Jul 21, 2013, at 10:15 AM, Lloyd Wayne Reece wrote: - I am in need of a set of tires for my ice but the same would apply for > my EV in the near future. - How can I get the information on LRR for the different manufacturer? - Is their a single source where this can be had and does low rolling > resistance mean that they will have a much lower milage rating and if so - do they really save any money or energy?? > - I am looking for 225/60 R 17.
