just to understand you correctly, you are comparing a DOT mud terrain tire to a sticky competition compound tire?

 

Yes..

 

You can't compare the 2.

 

can't compare the two....on a side note your air down pressure was not near enough on the MTR's on standard rims....I air my 37" MTR's down to 10-12 without bead locks with no issues

 

Wow 10-12 psi without beadlocks, that's ambitious...

I thought it was a fair question given the fact that MTR's have been very competitive in King of Hammers events and a jeep one our tuff truck competition this year running the MTR's.

I guess I wanted to know if the MTR's require low pressures for them to start working properly?

Thanks for everyone's input... It's been very helpful...

 

I messed around with the air pressure on the MTR's for a little at EJS in Moab this year...at 14-15 I wasn't seeing much bulge and even though the traction was good I felt it could be better. Dropped down to 12 then 10 for the rest of the week and they performed awesome!

 

Good stuff mate... Is your jk a 2 door or a 4 door? And are you running 37's? Thanks

 

Like stated above I would play with your pressure. On a 35 MTR the difference between 15 and 10 is quite a bit. I now run between 10 and 11 on non-beadlocked wheels,

never lost a bead or burped air

 

Thanks to all you guys for your advice.

I'll try lower pressures offroad on the MTR's and see how that go's.

I'm officially a Trepaholic tho... I ended up buying that second set of Treps last night, and I'm glad I did because they look pretty much brand new. Plus they have been grooved through the centre, so they've got heaps of tread remaining.

 

I have run 37" MTR/Ks at single digit pressures on a 8.5" wide non-beadlock wheel. No problems. I think they do need a lower pressure than some other tires.

I'm running the new Falken MTs now and 12psi on them feels like 8psi on the MTR/Ks.

You can see how soft the rear tire is at 12psi.

Thanks mate. I'll try that on the weekend. I'm taking the wife and the 3 little ones for drive out in the bush on the weekend, so I'll see how the mtr's perform on 10psi... I'll report back with my findings/opinions.

 

Nothing that hasn't already been said, but drop that PSI to 10 - 12 and you'll have a different tire on your hand altogether. Never had any problems airing down that low on non-beadlocked wheels here either.

same as others have said. i run the 37 mtr's at 8 psi usually with no issue. i used to run them on the stock alloys, and now i have them on some slightly wider steelies. its helpful to just not have a super wide wheel to keep it from burping
