Tubeless bias on stock rim
I have been reading about running tubeless tires and haven't found exactly what I need. Most posts are about running radials that way. I have new load range C bias 6.50 x 16 hiway tread from National tire on the front. Last night out for dinner with the wife came out to the woodie (not exactly finished) and found the second front tire flat in 200 miles of driving. The tires are marked 'tubeless, but I ran tubes. The tires have heavy ribbing on the inside and this seems to chafe the tubes. I have read many posts about running tubless but not usually bias ply. Should I just lose the tubes? Rivets not a problem? and do I need a special valve stem, or just garden variety? I'm getting tired of my tire irons....Thanks in advance.

Re: Tubeless bias on stock rim
IMO pull out the tubes ,seal around the rivets with good silicone and use the correct valve stem.Done this several times(with radials) with no problems.I don't imagine that bias tubless would give you problems.

Re: Tubeless bias on stock rim
I found out many years ago that you can't run tubes in tubeless tires, the tubes will fail every time, usually where the tube intersects with rim.. If you do use tubes in a tubeless tire the tubes must be for tubeless tires.
As a precaution it might be a good idea to seal around the rivets on older wheels if tubeless tires are used. There are stems available that will seal to the rim with rubber gaskets and a locking nut. It is also not a good idea to use radial tires, mixed with bias ply on a steering axle. Radial tires on the drive axle with bias ply on the steering axle is OK.

Re: Tubeless bias on stock rim
Just curious. Why shouldn't you use radials on the steering axle?

Re: Tubeless bias on stock rim
That's funny, 'cuz my '40, my '65 Vette, my Chevy pick-up and Momma's Tahoe all have RADIAL tires on a steering axle...........NO problems so far! Where do you come-up with this ridiculous stuff? DD

Re: Tubeless bias on stock rim
If you have a mix of bias and radials, the only acceptable combination is bias on the front and radials on the back.
That's where they get that stuff from, it just gets misinterpreted sometimes. GB, I have switched my 58 GMC to tubeless. They are radials though. Mart |

Also, I've heard tell of folks having some serious accidents by mixing bias and radial tires on the same vehicle

Re: Tubeless bias on stock rim
Looks like a few of us were writing around 11:37. Both of my employees are playing hookey today so I smeared some silicone on the rivets, found an old brass tubeless tire stem with a nut on it to expand the rubber plug. Excellent device and the reason I have a specific drawer for saving everything. Tire has been holding 32 lbs for an hour and a half. Now I gotta pull that other thin Korean tube from the drivers side front and find another expando valve stem. Hoping napa has them. Thanks all for the quick help. GB

Re: Tubeless bias on stock rim
There is a standard rubber type valve stem that fits, I just call it a "fat" valve stem and tyre guys know which one I mean.
I just looked on UK ebay and the proper number for the type is TR415. I don't know if that number is used in the USA. Mart. |

Re: Tubeless bias on stock rim
On my '47 I'm running Coker Classic tubeless bias ply on 15 inch merc rims.
Regarding mixing of Bias and Radial tires in any arrangement, never would do that .... i.e. what kind do you use for the spare tire ? two spare tires ? Get a flat and what do you do ? Unless you explain the situation to him, what does the guy in the shop do ? |
