have any of you guys run the 40" mtr's in deep snow, im looking for a tire that will really air down nice and float on the deep soft stuff, im contemplating 44" fun countries as a dedicated snow tire, i'll just have to block down my bump stops and cut the fenders a bit more, and i'll run a 38-40" tirein the summer. if the big mtr's work really good in the snow i could get by with one set of tires for everything. i want something that works better in snow than the 37-1450 toyos, 39.5 iroks, or 38-15.50 gumbos (most peoples top 3 deep snow tires) lets hear it, pics would be awesome too. thanks -DT

I like my 37 mtr's, 40's would only be better. I doubt they'd work better in the snow than the Iroks though.

From what I've seen, the toyo's aren't that great in the snow. They have really stiff sidewalls and need to be aired down to nearly zero to get the sidewalls to bulge and tire to float in the powder. Maybe the problem is just that they need to be treated more like a bias than a radial as far as airing down goes? Once I finally convinced the rigs running those tires in our group to air down way more they did ok.

Depends upon the snow. How deep are you talking?
If it is more than 2 or 3 feet deep, it would be better to stay completely on top with 10-14 inch wide wheels and wide/tall tires aired down to near zero psi. The tread design is less important if you are staying on top. A super aggressive tire like the Irok would be the way to go in normal snow. I wish I had my rig on 40 MTRs up and running as I have 3 feet of snow at my house RIGHT NOW!

mtrs or iroks are your best choice. Definitely don't go with the toyos for snow. I ran mine this weekend for their first run in the snow and they sucked. I aired down to 3lbs to get them to bulge out a little more. slow and go did it with them, but as soon as you wanted to romp on it, they'd just want to dig, where the mtrs and iroks were able to keep the pace up and stay on top. I ran mtrs before and I thought they were awesome in the snow, but I also have seen many people running iroks in the snow and those tires get it just as well.

Went from 37" mtr's to 39.5 bias Iroks.
Thought the mtr's where the shit, but then came the Irok. New king for sure. Also wheel with guys that run the 36/37 irok bias, outstanding. I think the Mtr's are just too small/narrow to compete. Plus the cool wrinkle wall look I get from the Iroks.

Gumbos are the best snow tire in my opinion right now. I have a set of 42 Iroks im waiting to try out though. Ive run a set a 35 mtrs before and was very impresed. Toyos are great in the snow. Get them siped and run them around town for a day or so at about 6 psi to break the side walls in and they will perform great for you.

Blue mt runner is right the gumbos are hard to beat just cause they are agressive and very soft. the 40" mtr will do better than a 35" or 37" mtr but the 39.5 Irok is your best bet trust me or 42" Iroks the mtrs are still 12.5 wide right. If the were wider they would do better but get Iroks and atleast 12" wide rims and stauns run them 0-2 psi and they are the ticket. Iroks.

hey Guys I was wondering why know one mentioned or uses 39.5 super swamper Boggers in the snow ? or 39.5 super swamper TSL,s in the snow

Is the Irocks that more superior over the boggers or TSL tires in the snow ?

The way the bogger tread is made basiclly like a shovel limits it's ability in the snow. The tsl is the 3 stage lug design with very rounded corners and hard compound even the radials. The iroks have a 3 stage lug design but with many sharp corners and different shape lugs than the tsl. I have ran with people that had 36 and 38" tsl radials in the snow and my 35" bfg km outran them imbarissingly bad.

I have both the 40" MTR's and the 39.50 IROKs. I use the MTR's for street and light trail driving and the IROKs for the tough stuff and snow and they are by far better than the MTR's in the snow, rocks, sand, and mud. I loved my MTR's but the IROK's are the new king on the block.

I'd go with the FC's IMO there is no other comparable tire available for it's ability to float on top of snow and ability to keep from digging.

as for the boggers; deep snow, and we're talking like 6' of snow requires you to float on top. ALthough it's true that snowmobiles may displace enough snow in some situations to propell them, very few vehicles have the hp/weight ratio to do that. In that case you want the lowest possible ground pressure and that is usually found with sand tires. Tires that dig suck in snow.

Hey Guys Thanks for all the feedback on the Swampers, I currently run 39.5" TSL's on beadlocks airdown to 5lbs on my CJ and have been doing pretty well in the snow up to 3' deep, after 3' or so its pretty hard to keep my 60s diffs above the snow and Im just purely plowing along with my V-8 forward momentum's. But it seems everyone agrees and swears by the IROCKs now as the only way to go. But I seen also that when the snow melts in spring and the same trails where everyone is riding ontop of the snow, now has to get down and dirt in melting snow & runoff mud my TSL kick ass and I seen the IROCKs lugup and spin in the mud. And another thing I seen TSLs seem to last longer, and not round off and tear lugs off as much.

mtr's suck when the rocks are wet/muddy, never really used them wheelin on snow...tsl sx's were my tire of choice for floating on 4-5 foot deep snow covered roads, but you had to crawl...they didnt have iroks back then...i have a set of h1 wheels to put a serious wheeling tires on soon, mtr's and black steel wheels for mild wheeling-camping/ daily driver duty currently...im looking for 39.5 tsl's, iroks wear out too rapidly
