I think I remember a wood stove in the dining room (most likely where the Harley tank was until ordered out of the house by the Domestic Goddess).

Watch out that you don't heat soften the tire to the point it cannot stand the mounting air pressure you put on it .....

Heat it up empty then air it gently to 50 pounds or less to see if it will pop over the bead for you.

Airing it first to 50 and then heating it will make MORE than 50 lbs of air pressure AND heat soften the rubber some ..... mebbe a bad combination, that .......





MM,

I just bought 500 each 150 grain perfectly normal .308 hunting bullets that fit your Swiss K31 rifle, I'll bring you some when I see you next.   Heck, I will even powder coat them with hexagonal boron nitride when I do all of mine.

  ...... then you can go load you up some perfectly normal 150 grain K31 rounds that won't kick so durn much ......
     

Buy a smaller inner tube  

(that tire is a hundred bucks invested -- and it is not a sunk cost yet as a $10 tube makes it a viable project again)

   or if you bought it local and can swap it for a wider/taller tire, hey go for it.

You can push aerodynamically efficient 150 grain jacketed slugs to 2,650 fps using book standard K31 loading data.

Or you could shoot what I sent you, 165 grain MatchKings at about the same fps.

The MatchKing bullets penetrate 6-7" then it makes an expanding cone of destruction out the far side of the deer as it tumbles and comes apart completely.

Messy, but good .....   you will be able to track them and they won't run far.   Do hit them behind the shoulders in the lungs as hitting a near shoulder would waste both of the shoulder hams.  

For the life of me I don't understand people not using enough bullet to do the job and having to break a shoulder just to anchor the animal and keep it from running off alive.   Hey, there isn't that much edible meat on a small deer anyway.



And hey, that IS the nicest deer impact picture ..... go search "sierra matchking hunting pics" if you want to see the ugly ones .....

I like guns that kick some,  but not as much as Lancer does,  but more than you do.

I am going to make some 7mm heavy slug rounds at a very MODERATE velocity since I played all the heavy recoil games I care to play with that rather light rifle.

Ditto with the big '06 rifle, I will do me some more moderate fps 150 grain rounds looking for some stellar accuracy out of the gun, not searching out maximum wompingasskickingitus as I have done some of those already.

What you already have in the K31 will kill a deer plenty dead, MatchKing or the 170 grain cast slugs.   Since you like to shoot from a raised stand at very moderate distances, you don't really need the long range ballistics either.


============================


Are you saying you can't swap out your skinny tire at where you bought it, or are you going to just going to go buy another one?

Did you get the bead to seat?   If so, leave it for a day to stretch the bead zone good, then deflate it to zero (take the valve out) a half a dozen times and let the tube contract and expand to work itself around to conform to the smaller space.  

Tubes are elastic in both directions, you know -- the walls can compress a bit or stretch a bit to line up with the space they are in.

Airing it down to zero and leaving it a while, then airing it back up just until the valve stem has very very light push back (take the nut almost off so you can move the stem in and out freely) is the trick, that is if the bead itself will stay mounted on the rim while you do that.

Properly designed and fitted to the throat, cast lead bullets do not lead like you are used to seeing in revolvers.

30-30 Winchester was "the lightning fast" magnum jacketed round when it first came out with its light 170 grain bullet -- people gushed about how it killed like lightening.   Black bear, elk, moose --- it could kill anything in North America.   Five instant repeating shots, too.   A smokeless wonder round with jacketed expanding bullets that worked at any distance you could shoot it accurately.

Now it and the 7.62x39 are in the same ball park, considered puny rounds by the shooting press.

Fact is, both will kill a deer or a black bear just as well as they did originally.   7.62x39 can be loaded with heavier expanding bullets for hunting, too.   You just lose powder space while doing so.

I use Gas-Checks on my cast rifle bullets and my own concoction bullet lube   , been doing well with it for years.  Long as speeds stay below 2200 fps , things are better than jackets , 2200-2400 is "iffiy" , and above that is TOTALLY out of the question.  Lubed , lead bullets with gas checks "Slide" out the barrel "Slick-as-a-button"  
My plain base pistol cast bullets get Alox lube and stay below 1200fps.  Think 22Mag 1950fps no gas check / powder lube.

I can't take that 65 series tire back , but thats OK I've already replaced one of the hay rake tire and the other one need replacing now. (Dry Rot)  
I put the tire , tube , rim together in the house last night .  Its pouring rain now but when it lets up some I'll go to the shop and add some compressed air to the mix , might even add some tire lube if the inner tube hold air.       If  it holds air I'll bring it back to the house and set it by the wood stove for a while and hope for the best.
If it don't hold air ...   ...    could turn-into a trip to Lynchburg Choppers to see what my buddy Pat has in stock.

All that snow is just a bit North and West of us now , but the day ain't over YET.  

I'm curious why you chose a 145/65-15. That tire is nearly 1.4" shorter than stock (or 2.5" shorter than a 140/90-15).
