Treps Vs MTR Kevlars

Hi Guys,

I've been running 37 inch MTR Kevlars for a while now on non-bead locked rims and was pretty stoked with their performance off-road. I would air them down to 18-20 psi off-road.

Recently I bought myself a set of 37 inch Maxxis Trepador sticky's on beadlocked rims. I can obviously air down to a lot lower pressures than before, generally 10-12 psi. There was night and day differences between off-road performance in mud and on rock between the MTR's and the Treps. The Treps were far superior in every way on the bead locked rims. Do the MTR's need to be mounted on beadlocks to come alive or start working properly?

My question is, if I had the MTR's on beadlocks, would there be such a gulf in off-road performance? Obviously the difference would be smaller, but I'm after people's first had experience with the 2 tires in question running bead locked rims.

Reason for this question is, I have 2 sets of MTR's in the shed and I can purchase another set of sticky Treps for a good price, but I'm not sure on which way to go...

Any advice is appreciated...

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

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

You can get the MTR in a comp csticky compound as well, not the same as the everyday tire. That would be a better comparison.

Some build info here:

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

it's not a fair comparison no matter what. 2 totally different compounds.

the MTR-Ks are a great tire (other than weak sidewalls) for wheelin most terrain, but a comp compound is gonna stick tons better.

but to answer part of your question- the mtr-k will work better when the psi is lowered. they work quite well for a DOT tire (kinda like the KM2)

Likewise. To date, have not lost a bead, 8" wide wheel

Big difference in grip from 18 psi to 10

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
