Conti MPT81 Pressure (and sneak peak at the NEW ones)

All the #'s you need to get the right pressures are right in front of you. Between the sticker on your door jam indicating your rigs F/R weights and what the pressure ratings on the actual tire you choose to use should put you in the "ballpark" of the correct pressures if you do the simple math.

Bringing this back up since i just weighted my truck and stumbled across it

My steering axle is at 8400 lbs, drive axle 9700 lbs
Currently running 70PSI which based on that continental chart would be ~5500 lbs per tire.

Seems like I gotta air down a bit to ~40 front and 55 rear.

@RAM5500 CAMPERTHING How do u like the mpt81s?

Thanks

WOW, that split seems quite extreme..

You run the front at 35 on pavement?
Sorry for the slow reply... I left into the backcountry for a bit!

Yes, 35/90 is what Earthroamer is putting on the official door sill sticker and manual for highway. It used to be ~55 up front I think. I'm not sure what drove the change in guidance.

Has anyone figured out what the "next generation" mpt tire differences are? Referencing the first post.

I'm looking to step into a set of 275/80r20s mpt81s here in a few months.

These should mount to a standard 20" wheel right? I'd like to use 2005+ superduty alloy wheels for both strength, cost, and looks.

The best deal I can find is on eBay from Colony Tire, out of Norfolk Virginia.

Thanks,

Even after talking with several folks directly at Continental and several large truck shops, apparently the only new thing is a little different sidewall graphic design and they had DOT printed on them.

I’ve heard (not confirmed) some of the older ones didn’t have the stamp, but it’s the exact same tire.

Careful buying the cheap ones on eBay, ask for a date code. Some are 6-7 years old. I wouldn’t touch them with a pole.

Only that @java fella buys tires like that 😜

Having raced motorcycles most of my life, rubber changes (hardens) when it sits around for years. Ask anyone that races if they’d run old/new tires.

Dont buy online unless they’re willing to provide a date code.

Great advice! I didn't consider doing that, but these are a different market altogether compared to how I've bought tires before.

I've ran used/old tires before because of budget constraints, and have always found buying new to be the best $/mile when it was all said and done.

My setup weighs right around 7500#, gear laden, so these should last quite a while tread wise if I can get new and keep the pressure right.

When I get them on the rig, I'll post back.

Thanks!

Just got my MPTs mounted to my 1st Attack wheels. Tires via eBay from Colony Tire. They’re current date codes (confirmed in advance) and had great customer service.

Did you balance with dyna beads?

Sorry just saw this. Had traditionally balanced. I need some Highway time to check it out to see. If any wobble I figure I’d go centramtics.
