I bought a new set of these BFG R1 245/40-18 and 285/30-18's to be mounted on the stock 996 rims (8" wide / 18" diameter and 10" wide / 18" diameter).

Mounting is a breeze, but getting the bead seated on these rims is proving to be a real feat. I have used a bunch of different tire lubes (incl. silicone based) and have pressurized as high as 100 psi. The outside bead will not pop all the way around however.

I also put a strap around the perimeter of the tire before pressurizing, as suggested on some forums. Also to no avail.

Any suggestions?

Joost - I have never had any problems with them.

 

Maybe its the ambient temps these days that harden up the rubber by a tad too much. Spoke to someone at BFG today and they recommended taking them inside the house overnight and try again with slightly warmer rubber and lots of lube.

Greg commented that his installer is having trouble getting the bead seated on his from time to time as well.

What rims are you using?

At least he's honest...

 

 

It is obvious they are not partial to the Dutch. I am glad to see that you bought the proper size so all you have to do now is give them to me.

 

There is an old trick to mounting large mud style truck tires when out in the back woods and there is no way to seat the bead. I can't explain because I really don't recommend it and there are some inherent dangers to doing it. Although I am sure if you Googled you could find some how to on it recommended from someone else.

And I will add, I have used this way before when in a pinch and it does work.

 

Here ya go,on Discovery channel no less, but remember, once again, NOT recommended by me.

Yeah, I saw a few of those vids on youtube. I am not planning on going that route. Risky at best when in the sticks, lunacy in my home garage.

If I did that it'd immediately double the value (and reliabilty) of your 951.

 

So you have it done by Discount Tires, or NTB?

 

I have the stock 5 spoke wheels.

 

Discount tire, or any track support operation. Never tried it in my garage, never could figure out where to put a tire mounting machine.

 

Crap, I hate it when the pro's have an edge!

I had my wife take one tire to my local installer this morning to see if they could get the bead seated. Success!

I called the owner trying to get him to spill the beans on his secret sauce. The only thing he eluded to was that he has a special trick and that it took two guys...

I have three more tires that I'll be taking there tomorrow, so plan on watching his guys while at it.

Will revert...

Viking,

The more I look into this, the more I am convinced that the lighter fluid trick is only useful (albeit suicidally dangerous) in those cases where the gap between tire and rim is too big for initial pressure to build.

My problem is that the inside circumference (at the bead) is too small for the rim, and I don't think a kaboom will help in that case.
