Hello,
Need your help with suggestions for a good front tire for my DTSwiss E1900 spline 27,5 with an internal wide 25mm in a mondraker dune r 2016. I’m only 70kg weight. I’m currently running with high rollers2 2.3 front and back but want to change the front to a wider tire without changing the rim . Any tips?
I intend to use it in a kind of enduro - aggressive trail here in lisbon region were it doesn’t rain often. We do have hardpack trails and rocky terrain

A lot of people dig the 2.4 DHR2 as a front tire, if you don't want to go all the way to a 2.5 DHF (which does run a bit small and should work well with 25mm ID rim still...).
Among tires that have slightly smaller profiles that should work with your rim, I really like the Michelin Wild Enduro front, especially in rocky terrain. It gives a lot of confidence on off-camber rocks and in heavy rock gardens. It's quite a tough casing and demands to be ridden hard though, it's less compliant and comfortable than a typical Maxxis at lower speeds. Goodyear's MTF is also a good choice for this kind of terrain.
Totally agreed with dhr2 maxx grip front and dhr2 rear as a great tire setup. As an off the wall suggestion, the conti's might be a good choice too. I have kryptotol rears front/rear on a 30mm iw wheelset for my trail bike... they run super square on 30mm iw. They might round out a bit on a narrower rim and perform nicely.
The dhf 2.5 were one of my options but they are only available in the WT , that I’m afraid it won’t work in my 25mm ID rim , or even an assegai 2.5 . I heard some saying that works, some don’t.
thanks for your insight
An Assegai 2.5 will work just fine on your narrow rims. It'll end up with a rounder profile which is good as a front wheel setup. The Maxxis Assegai is the best cornering tyre I've tried on hardpack dry trails.
The 2.3 Specialized Butcher has been surprisingly good option as a front tire. They aren’t quite in the league of an Assegai in terms of grip, but are easy to get along with. They have a rather square profile on 30mm rims, so one could assume, with a rounder profile on a narrower rim, they’d work pretty well.
I really, truly don't think the WT thing matters on a 25 or 30mm rim. It's a tire. If you start getting into really weird rim sizes like 19mm or 40mm you're going to start seeing some weird tire shapes but I think on a 25mm rim I wouldn't sweat it. I have a 30mm front and 25mm rear, not on purpose, just because I broke a rear wheel and 25mm is what I had on hand to replace it. It's fine. Don't stress it. Pick the tire you want. In a related story, I would never buy a Vittoria MTB tire in a million years.
You can listen to random people say stuff or look up video of what a 25mm rim and a 2.4, 2.5 wt is capable of. Try googling dt Swiss ex471, Maxxis, Bruni, Gwin,Hart, Brosnan to start with.
The Vittoria does have good reviews ….
I’m in this exact scenario, have just switched my tires from 2.3 HR2’s to 2.3 Specialized Butcher T9s which are definitely wider. These are on 25mm rims - not sure I’d want to go massively wider.
It does makes sense a square shape tire in a narrower rim, gets a regular profile…
other question is the gap between the center and side lugs , it will be more open ?! Doesn’t change the grip? Shouldn’t it be better to use a tire with intermediate lugs ? Like DHF vs Assegai ?
Using a 2.5 or 2.4 WT maxxis on a 25mm ID rim absolutely isn’t great. Your sideknobs are at a truly suboptimal open angle, and will(in my experience) start shearing off completely before the center knobs show any wear at all if you are the kind of rider that enjoys turning on hardpack.
Rims wider than 25mm and tires wider than 2.3 don’t really play well together if you are sensitive to casing deformation, knob spacing, etc.
That’s more or less what I’m afraid of …some people say it’s ok some not… I’m looking for experiences in cases similar to mine, and tires that would work fine for my region .
Schwalbe says in their charts,that it’s ok for their 2.4 tires to sit on a 25mm ID rim… so I was thinking about a MM supertrail soft or maybe the a Vittoria Mazza 2.4 that haves some good reviews
I have the opposite take. I've found that wider rims just destroy side knobs - and Maxxis seem to get undercut faster than most. I ran 3CTerra and 3CGrip DHR, DHF and Assegai on 32mm rims. Happier now on rims in the 27-30mm range.
OP, WT is just marketing blah blah blah to be ignored. LOTS of fast riders run them on 25mm rims.
You will get a rounder profile running a 2.5in tyre on a 25mm internal diameter rim. The sidewall will have less support so you will need to a) run higher pressure to avoid squirm or b) run thicker casing tyre. Mountainbike tyres in general are way too square. As we are now running longer bikes and bigger wheels we tend to lean our bikes, in cornering, way more than before. Having a rounder profile helps keep you on the side knobs rather than washing out on the sidewall. Look at any MX bike tyre and you'll see they have an extra set of knobs lower down the sidewall than mtb tyres.
