33's = increased risk of rolling off bead when aired down & at 30-35 degree + angles?

<snip> As for re seating it, the safest way is to always carry a ratcheting cargo strap, The 3 inch wide 10000 pound rated one, not the little skinny ones(unless thats all ya got, thenuse 2 or 3). You simply wrap it around the outside tread and crank it tight, this will push the sidewalls back to the rim. Make sure the sidewall and rim are clean of dirt and rocks or any other debris. then simply air up. A CO2 bottle is Ideal as it can give a short powerful burst when regulated correctly but if done correctly a compressor can work also.

Well... yeah... there's that way too but it's not near as much fun!

Just another data point...

When I go out rock crawling I air down to 15 psi with my stock rims and 33 Goodyear Wrangler MT/Rs. Have not lost a bead yet.

Prior to the MT/Rs I did lose a bead with the Duelers, but I think I was below 15 psi.

Just as shadow-warrior said, 20psi is the lowest you should go with most radial tires without beadlocks. If you are running bias ply tires, it is a different story. I run my bias ply tires down to 12psi and they just start to flex.

Same here... I experimented with my MT/R's running 8psi, 12, 15, 18, 20, 25, 30, and like 50psi on the same rock crawling trail over and over once.

Did not lose a bead with any of those pressures, though clearly some of those low ones are ridiculous and aren't a good idea.

All about how you drive - if you're thinking about it, you'll probably be OK!

If you want to run lower pressures, the true beadlock is the way to go. I have the Walker Evans beadlocks and have used them for over a year. In some very difficult places I've dropped them down below 8 psi with no problems at all.

On stock rims I run my pro-comp x-terrain at 16 and the pittbulls wich are biais at 13 and you just start to see the flex. Never lost a bead yet.

Ratchet strap is the best for reseating no danger. Other option is ether inside not like on the video, light it up as soon, as the bead is back on, air up as fast as you can. The strap is much safer. Always clean the rims and tire before a bead of grease on the tire bead helps also.

x2 on beadlocks. They are definitely the ideal. I just don't have the cash for 300 plus PER rim. They are pricey.

The LTB's grip pretty well and conform a good bit at 12psi and are no where close to loosing a bead. This is of course due to the difference in the way bias plys are constructed and how thick/strong the sidewalls are.

Thanks to everyone for your input about bead locks, methods to reseat tires, making sure I have a compressor, etc.

Specifically - the question was focused on the fear of rolling a bead if upgrading to 33's and aired down to < 20psi on stock TRD 16" rims when at extreme side angles (not just when crawling or in sand).

Thank you 1911 for this pic!

That's the type of angles I've been looking at more and more frequently (unfortunately) on the inclinometer.

I've had my 34" x 11.5" Toyo's on stock steelies aired down to 15psi at this angle in Moab and had no problems holding the bead at all:

On resetting a bead with fire you BE VERY CAREFUL YOU CAN DO SOME SERIOUS DAMAGE TO YOUR SELF

A powertank/CO2 and ratchet strap is the safest and most effective way to do it on the trail.

Depending on the type of trail I'll run at 25 20 or 15-18 285/75/16 BFG AT's on Toyota wheels.

[DominicG]

I used to air down to 14-15 all the time with my 33's, never had a problem.

Now i air down to 12psi with my 35"s.


Just be careful and you'll be fine
