    Summer tires 27.5x4.5

    New rider, 1st post.

    Picked up a Farley 5, fun bike, rode it all fall and winter. The 27.5 x 4.5 Gnarwhals worked great on frozen old pasture, woodlot bushwhacking, snowmobile track, a lot of steep climbs. I love the big rollover and the aggressive tread.

    My summer riding mix will be more dirt single track with some gravel and pavement. With summer tires I could save the tread on the Gnarwhals and maybe get faster lighter tire. I have the 80mm mulefuts, don't want a 2nd set of rims at this time. My LBS would do the swap he has the 4.5" 120 tpi Barbagazi and 3.8" 60 tpi Hodags in stock. What do you guys think, worth it to change or just grind it out on the Gnarwhals? How do tires hold up to being remounted several times tubeless?

    Donít buy new tires until your old ones are wore out real good.

    I have hodag's on one bike and maxxis FBF's on the other. FBF's work well in the summer months.

    Barbe's for sure, for many reasons.

    Quality tires can be mounted/used/unmounted/remounted many, many, many times, no problem.

    For what you describe, Barbegazi or Hodag for sure, depending if you want to keep the full 4.5 volume, or want something narrower and a bit faster. The Hodag will drop your BB some though, so consider that. I think saving the Gnarwhals for winter is a good idea, and these tires can be mounted/unmounted many, many times as mentioned without damage.

    If you want to splurge for new wheels at some point, go for some 29+ with something like a WTB Ranger.

    If you're using 80mm rims, I would go with the Barbegazis. I would think that all of the 3.8 tires would leave too much rim exposed.

    FYI, I do use 4.5 Gnarwhals for snow but not dirt. Too much grip and rolling resistance...and they're studded.

    I've actually got 3 sets of Bontrager 27.5"x4.5's for my Farley 7
    (They were on sale 20% off last year, plus I had a bunch of LBS coupons to use up)

    Studded Gnarwhals for Winter Snow/Ice, Non Studded set for Springtime Mud traction
    and a pair of Barbegazi's for faster dry Summer conditions and occasional pavement use.



    Stock Mulefut 80mm wheels and have not gone tubeless yet, still shopping for a Carbon wheel set.

    When I got my Farley it came with the Hodags on 80mm Jackalopes and knew the Barbs were coming out soon. Got the Barbs on as soon as I got them. I ride nothing but FL Panhandle Beaches.

    Heres a shot of the Hodags.



    And Barbs.

    Thanks for all the replies. I went with the 4.5 Barbagazi. Aired them up hard 20/18 psi and did a 12 mile pavement ride. They seemed to roll well for a big tire, I'll see how I like them with lower pressure on dirt when it dries up a bit more. At the least I dropped a LB or more, got a quieter tire, and will be keeping the Gnars sharp for next year.

    One more question for future reference. What's considered optimum rim width for 3.8-4 x 27.5 tires?

    Many around here are using 27.5 x 3.8 on a 50mm(external) width rim for non-snow usage.

    50 to 70mm, depending on how and where they'll be ridden.
