OMGHi2U Who has used the Green Diamond Icelander tires?

Yep, far from winter, but I'm planning to get some new winter tires within the next few weeks.

I've been a long time Nokian user and have been running their WR tires for some time.

My goal with these tires is similar to my Nokian use.
-winter driving, snow, ice, cleared and paved roads
-doubles as my rally-x tire, must handle dirt well and lateral loads
-triples as my ice racing tire, must handle ice/snow well

The Nokian WR is a nice tire. I wouldn't mind trying the WR G2, new Hakkapeliitta R, or new G2 SUV, but I'm looking for more ice traction as this is something that is quite lacking with the all-season compound WRs. I could just go with an ice tire, but I want something usable/durable for rally-x, and nice to drive on when the roads are clean and dry. The Green Diamond tires peaked my interest for these criteria. As well, they too are design as an all-season tire, doubling as a competent paved road cruiser. The sidewalls are supposed to be firm, coming from H and V rated carcasses, and the tread pattern, spacing, and depth is decent enough for dirt use. Except for the added weight of the tires, they seem like a decent fit for the job(s). The only real negative I've heard so far is road noise. Apparently, they howl a little bit, so I've seen mentioned.

What I'm looking from any of you folks who have actually run these is more specific information as well as overall impressions of the tire. If you've used other brands/models, feel free to compare and contrast between the tires.

bump. I know a few of you guys have run them. (nhluhr, express_wagon, brandon, etc...)

There are small bits of info on them from folks, but most are brief and several years old.

Rich, the owner of distributing based here in colorado is a really good friend of my mom's lol they play in some of the same bands. i would say the tires are pretty good, ive seen him drive his defender over like 20 foot snow piles after they plow major parking parks. im going to give them a try because i can get them super cheap once my current snow tires wear out.

Alright, good job on calling me out.

Been couple full seasons with them...can't say I have experience with it on rallyX grounds + ice racing. Though I would like to try this upcoming season (Ice racing that is).

Dry = Drives like any typical non-performance A/S...not sporty nor sloppy in the handling department. Don't expect RE-01R like grip.

Wet = Drives perfectly fine when not pushed, but I have had squirmy moments when I make a sharp turn a bit faster than one should. I had Michelin PA2s also and they were superior in this department.

Snow = They do what they are meant to do. Confident and safe. Boston roads are plowed most of the time, so never extended traveling in the nastiest of conditions.

Ice = Advertised as a phenomenal ice tire, which they are perfectly adequate when driven with caution...don't expect the hands of god. Drive like an idiot on ice, you'll crash and much deserving so.

Wear = I only have maybe 12k miles on the GDs and they have been wearing like iron. It'll take at least another 4+ season with my kind of easy winter driving.

Overall = $125 shipped a pop, 205/55/16, it's on the higher end of the price spectrum size-wise. The real strong point seems to be the longer treadwear. No real downsides except they aren't phenomenal in the wet. Tires are recycled so it'll satisfy the hippies.

What other winter tires have you run that you could compare them to? Or is this your first step up from a 4 season to 3 season + winter pairs?

That's good to hear on the wear.

Could you explain the wet in more detail. For example, wet road, a little standing water, a lot of standing water, how does the tire fair? Does the tire hydroplane at all or run through standing water like a champ? On wet road, does the tire feel skittish, slippery, uneasy? Or does it feel grabby, well mannered, sticky? I've come to find the compound to be a big factor in wet road behavior. The tread pattern controls deep water evacuation, but it can not make up for a poor compound that doesn't like to grab the road. I'm curious your take on the Icelanders in this manner.

How well mannered is the tire at and around the grip limit? Is the tire well behaved during grip<->slip transitions? Is it predictable or does it seem to more randomly kick out on you? How does it feel up to and over the grip limit? Does it tell you its reaching the grip limit or is it more abrupt and instant? Is the tire easy to work with around the girp limit?

One concern I have is with the use of carcasses of other tires. They don't really have control over the entire tire design and can't really control the behavior of the tire. Mixing and matching carcasses also makes for more random behavior, like ride, flex, contact patch control, etc. It will all vary depending on the carcass they happen to use that day. This kind of makes the questionable for sport use, despite them using H and V rated tire carcasses.

although I have not tried them I tend to steer clear of retreads as I have seen to many problems in the past ... and you are considering using them in extremely harsh conditions and stresses when racing ... just doesn't sound like a good idea to me. stay with the Nokians

True. I haven't really heard about any specific issues with the Green Diamonds though for tread issues. However, I have heard about balance problems and the need of a lot of weights on some of the tires. This bugs me some...along with their overall weight. However, I do like the carbide idea and ice traction and the good wear.
