    I tried the search and wasn't successful finding any existing threads on the latest version of the PR4 Trails. I have the PR3 Trails on my 2012 GSA and have been very satisfied with the on road performance. I have about 7,500 miles with a lot of two up almost exclusively road and several trips packed fairly full. The rear is getting fairly worn and flat in the center. There's still some tread good tread but I wouldn't ride off on a long trip on it. The front has lots of tread left but I like to swap tires in pairs.

    So, to get to my questions. Has anyone installed the PR4 Trails yet? I saw a review that says different center/harder compound for better mileage.

    Thanks for that link. I guess I just search this area of the site. Tires ordered yesterday morning and being delivered today. That kind of turnaround still amazes me.

    I may use the Kaurit Moto tire changer I got on the group buy here to do the first tire swap on my GSA. I had one of the adapters turned down and bought a Parnes balancer. If all goes well I'll post it somewhere. I may have to drag out the HF tire rig just for the bead breaker.

    If anyone has used the Kaurit on a BMW wheel and has any advice I sure like to hear them now.

    These tires went on easy for me. These tires don't have a balance mark so don't bother looking for one. The only problem was the front was still compressed enough from shipping and the beads didn't want to make contact with the rim. A ratcheting webbing strap around the circumference took care of that. This was my fifth or sixth time changing the tires and it gets easier each time. Time for from breaking the beads(hf breaker) to both tires off and the new ones spooned on was 10 - 15 minutes. The first time I did it on the GS it took me a long time. Check out the videos on YouTube and this site for tips. Definitely use a lube of some sort. I really prefer plain old dish soap with water in a spray bottle. Helps not just in changining them, I liberally spray the bead area when setting the tire beads with my little compressor. I just use tire irons.

    I wanted to post a follow up. I installed the PR4 Trails and had a friend to assist. We used the HF to break the bead on the old PR3 Trails.

    I had the Kaurito outfit to install the new all set up. 4 hours later after using a combination of the
    HF,
    Kaurito with
    Marc Parnes balancer center adapter,
    NoMar bar,
    Mojo bar,
    and three spoons. various strips of old inner tube and lots of lube the tires were mounted.

    It was my first experience with a BMW wheel. The rim protectors I had bought were too thin to go over the edge of the GSA wire spoke wheel.

    Total time about 5 hours. I'm doing this wrong. I'll admit some time was due to trying not to scratch the wheels and we succeeded there. I don't want to mentally total how much $$$ I've spent on tire changing tools. I went into this thinking I'd make a short video of the easy peasy tire change. I'll continue to change the small tires for the training bikes in the fleet but an hour drive to the BMW dealer and some cash and go sit in a Starbucks till they're done sounds tempting. I really wanted to have this one go smoothly.

    A short ride is planned today and a longer rider tomorrow. In the 50 miles I've ridden so far I like the PR4 Trails. I got just under 8,000 miles from the previous PR3 Trail rear. The front had substantially more life left but I always change in pairs.

    Is there a tire changing fail threat this belongs in?

    My first time was just as tough. But I only had tire irons then. Now I have a bead breaker that works well. The rim protectors I bought didn't work either. I use scrap pieces of really thick leather now.

    Put all that "stuff" on Craigslist, buy three good irons and do tires in twenty minutes..

    Wrap a small handful of airsoft pellets in cling wrap, drop in tire before mounting and you can dump the balancer also.

    I had the Trail 3's and replaced them with the 4's.
    They seem to me to be a better handling tire.
    I'm a very happy camper. YMMV

    Put a PR4 GT on the rear of the LS yesterday...only just scrubbed it with 50 miles but it feels good.

    It replaced the OEM Conti Attack 2 which was done at 8,500 miles.

    Just waiting for M to get their chit together and release the Trails as i will need a front in a couple of months.

    That looks like a 100% street tire. Are the PR4 "Trail" a pure street tire? What do they look like?

    The pilot road 3's and 4's are indeed a street tyre. The 'Trail' refers to the sizing, no difference in the tread. Fairly big difference in the design of the 3's and 4's as well. They have gone for a wider 'hard' compound in the centre in the 4's to appease the gods of mileage; mistake IMHO; I will take wet weather grip over mileage every time. Tyres are way cheaper than a spill:)

    Yeah the only trail part of the PR4s is the word on the sidewall... its just sizing...that said they look like any other 90/10 tire to me.

    I think the trail rear tires has a softer center section than the other versions?

    I had a look at them, but it seems the front isn't available in the correct size for the GS LC. 110R19 is available but no 120R19

    yeah , the word "trail" seems like kinda a joke when you look at that tyre.

    I wouldn't describe the anakee 3 as a trail neither. But those type of tyres are ideal for my kind of road use.

    Is that an offer to test the time it takes to throw a new TKC80 on a local bike?

    As a side note do you have a tire groover? I'm toying with the idea of grooving the K60 you mounted for me 7500 miles ago.

    Here's a photo of the rear PR4 Trail. I was very impressed with the PR3 Trails. Rain, dry, 2-up. I've got about 200 miles on the PR4Ts and like them. New tires always feel good under me. I ride some gravel roads occasionally but nothing requiring digging in for traction. I'll take the trade off for superb asphalt grip for my kind of riding.

    Right...seems that some lucky people in Europe have got the LS sizes but here state side its no dice.

    They were supposed to be released in FEB i've heard that late APR to mid MAY for the trails.

    Just finished the 37 mile commute to work...its a nice tire...don't think i'll need the soft here in AZ.

    But it will be interesting to see if the soft is a 4,000 mile v 8,000 compound.
