Winter tires LRR?
I see a lot of MPG competitions where people use some really obscure brand of winter tires (competitions are held in warm months). I havn't been able to find anything on the internet about winter tires offering low rolling resistance, but is anyone familiar with any comparisons between winter tires and tires rated for low rolling resistance?
|
Look on Tirerack.com, they will sort by size. Then pick extreme winter and then Eco Focus for green tires.
|
Nokian advertises many of their winter tires to be LRR, and my experience has been that even Hakkapelitta 4's, which aren't formally rated as LRR (too old a design?) are within spitting distance of the best all seasons available for my car. They're also incredibly good snow tires.
|
So does that mean winter tires do, or do not have a better LRR than the standard advertised LRR tires that are all season/summer tires. I live in texas and it never snows or ices, so i really am just looking for something with the lowest possible LRR.
|
Nokian makes excellent winter tires and they claim most are LLR. My experience is they are. I noticed no improvement in mileage when I changed from Nokian WR's (all weather LLR tire) to my Bridgstone Ecopia's ( well rated LLR tire). My Hakkapellita R's are better than than the Michelin's before them in snow and ice. They give a little worse mileage, but that is mostly because they are oversize and much heavier IMO.
That said, don't even think about putting winter tires on in a hot climate. there is no benefit at all and they won't last. Find a well rated all season or summer tire. |
Yeah, winter tires use a rubber compound which is too soft in warm weather, you'll eat the tires off in a few thousand miles.

Just A Car Guy: The magic triangle of tire technology Based on this, look for tire with silica/silane in the rubber compound. In Texas I'd be worried about hydroplaning. https://1.bp.blogspot.com/-ajBoFzZRQ...79703420_o.jpg http://justacarguy.blogspot.com/2017/08/prop-and-skeg-marks-on-top-of-van-only.html |
That's a great picture of the van! I usually hit stumps with my prop not mini vans.

What the image doesn't explain is that tires with simple substitution of silica/silane for carbon black are WORSE for treadwear and the rubber compound has to be readjusted to get that treadwear back - AND most importantly - that tires with excellent wear properties are NOT going to be good for RR. PLUS the term *LRR* is a relative term. It means *better for RR compared to tires with the same grip and wear properties*. A LRR tire can have worse RR than a conventional tire because the tread compound can be reformulated to emphasize any of those particular properties (at the expense of the others!) |

Pretty much EVERY tire uses silica nowadays. It's old technology. The question is, how can you tell what the RR level is compared to the tire's grip and treadwear? Unfortunately, you can't. Grip and treadwear are delineated by the UTQG rating - required for all P type tires (except for winter tires!), but RR is more complex and doesn't lend itself to simple testing/labeling. It varies by tire size - even for tires built exactly the same. HOWEVER, RR varies more between make/models than it does for size, further complicating the issue. This means that trying to gain an improved RR by changing tire size yields small changes, where changing make/model yield larger changes. A proposal to change the UTQG rating system to include RR has stalled. I don't know what the current proposal is (it was announced, but not published!), but a previous proposal ran afoul of the problem is tire size and how to label. |

It looks like no one's discussed winter tires here in 2 years. Has anything changed?
I have steep hills, lots of snow and ice. R2 or G3 for the Camry? Both have equal LRR properties? Any new options, or are nokian still the best LRR Winter tires? Any other tires on the attached cr winter tire list, LRR & worth considering? |
I just put Cooper Evolution tires on the '04 Forester and Goodyear Viva 3 on the front of the '07 Accord just in time for the ice storm.
|
Nokian Hakka R3s are excellent. They are "ultra" low rolling resistance; while the eNtyre are just low rolling resistance.
|
Alright, where can I get the lowest price? Wanted to get them today, if I get a great deal. Did I miss the Black Friday specials?
|
I've ordered lots from simpletire but sometimes simpletire and others sell them cheaper on ebay. Ordered a pair from walmart.com ended up coming from simpletire.
|
P215/55R17
Looks like best price goes to Simpletire.com $158.38 + tax free shipping R3 Wrg4 $121.47 + tax free shipping Looks like today is the last day to get the Black Friday deal, ends wed 10am. |
I got the R3 today, looking forward to higher fuel efficiency!!
Consumer Reports says wet braking is poor, handling, hydoplaning, dry braking is not good. Can anyone share their R3 experience with these properties? |
Unfortunately, sears refunded, said they weren't able to get it in. Guess I'm stuck with OHTSU all seasons this winter. Fortunately, not much snow this year.

Thanks, bud. What I wouldn't do to get 118 mpg, is it possible in a non hybrid 2014 Camry se?
What is the most fuel efficient all seasons tire? |
If you need a "real" all season tire - and by that I mean actual snow and ice in the winter - then I like the Nokian WR. They are currently WR G4: https://www.nokiantires.com/tires/pa...weather-tires/
Nokian call them an all-weather tire. These are roughly similar to the eNtyre for rolling resistance. |

Anything is possible. I'd suggest half from drivetrain and half from aerodynamics. A good benchmark for aerodynamics would be Aerocivic For the drivetrain I'd see if there is room for a 20hp E-assist altermotor. |
I would settle for 117 MPG, but I have low standards.

Everything else I know is in that thread, but you could compare the performance of the hybrid and non-hybrid versions of the E-assisted vehicles. Honda's IMA system may be similar. |
I was searching for some information on a good set of Allseason tires that will handle the harsh winters in Wisconsin. That search led me to this thread. What are some additional or NEW options got winter or all season tires that you all have used ?
I noticed the Nokian WRG4s seem to do well all year. However reviews seem to show a complaint on how they wear and "howling" after 10k. With needing a new set of tires ideally a good set of all-seasons would be the most cost effective, but I'm open to all ideas. |

So that's where I'm starting to lean towards Allseason due to funding and availability of items. |

My Notchback Types III and Superbeetles all had 4x100, sorry to hear there are none in your scrapyard any more. |

I'll call the same yards and request the rims by number again and see if I can come.up with a set . http://www.thedirectory.org/cities/W |
Actually located a set I'll be picking up tomorrow after again going to the Ole faithfull craigslist and finding what I couldn't previously.
https://sheboygan.craigslist.org/wto...544036479.html The seller said he'd take $80 so I'll be snagging them tomorrow. He confirmed they are 4x100, and im thinking depending on the condition I might try and sell the tires for something like $40 for the set to recoupe some of my cash . |

Aside from spacers I belive they and the mounting of my winter tires were a waste of money. |

Back to the drawing board. |

I've never used spacers, are they safe to use? May seem dumb but I've worked on my own cars for some time and haven't used any and don't know anyone at the moment who does .
I located the set I'd need based on 4x100 and the part number I was told by the local parts store. Dorman 711-915 4 Lug Wheel Spacers https://a.co/d/72UGVJ5 |
