radial tires

Post by wvst » Sat Jan 24, 2009 2:00 pm

Can somebody help? Do you need to install the runflat with the radial tire or can you safely mount the radial tire to the radial rim without it?

you need either a beadlock, or a runflat to safely run the tire

You don't have to have the runflat but you really need at least a beadlock to keep the tire bead firmly seated to the wheel (12 bolt wheels). Without a runflat or beadlock it is almost impossible to inflate the tire (it can be done but a real pain). It is also much easier to knock the bead loose if you hit a curb or big rock and cause a flat. If you use an aftermarket wheel that has the bead lock as part of the wheel lip then nothing else is needed. Just a note, without the runflat to hold a flat tire off the ground a few inches you can't get the jack under the lower a-frame to jack the vehicle.

A beadlock is a large rubber ring that is inserted inside the tire like a runflat except it does not have the extra rubber that looks like a small tire. It just looks like a slice of large sewer pipe...in fact some guys make them from large PVC pipe.

The tire can be inflated without a beadlock with lighter fluid. lol. Alex posted his video of that a while back. Neat.

Make sure you have the correct o-rings. There are 3 different ones..
.
the runflat need to be in the tire before it is mounted on the rim.
The 37" radial tire usually has a 1-piece rubber runflat in it.

wvst,

There are several types of runflat.
a magnesium one for the 8 bolt rims, an early two piece (inner and outer) rubber runflat and a later rubber one piece runflat.

Sounds like you have a later style one.

You can run the radial tires without a runflat or bead lock. I know, because I had my tire mounted that way for 4 years. That's the way they came with the vehicle when I bought it so I assume it was fine that way. (I didn't know better). I drove a good 10,000 miles this way and at least a 1,000 of it off road. Never had a problem. That said, I would recommend that you do put at least a bead lock in. I have corrected mine with runflats.

I will say that, as lkgindy has pointed out, they can be very difficult to inflate. I've seen two methodsused. One is using lighter fluid as Action mentioned. The other is an air blaster. I've seen these mostly at tire shops that do truck tires. It look like a 1/3 size scuba tank with foot long nozzle on it. They charge it up with high pressure, stick the nozzle in the tire, pull the lever, the BOOM, instant inflation. In most cases though it takes a couple of tires, especially if they are new.
