Tire chain size cross reference

Recommended Posts

I'm shopping for a set of chains to fit 31x13.5-15 turfs. I see sizes that are close such as 31x15.5-15 or 33x12.5-15. Would anyone have a chart showing what other size might fit the 31x13.5? Thanks Nelson

The 31x15.5-15 should fit nicely The side chains will over lap the sides 1" further on each side and you might have to hook one link shorter on the side chains but they will fill the bill for you. The 33" set would be about 6¼" two long. 31" vs 33" = 2" extra dia x 3.14 = 6.28" longer. The thing to look for is a set that = the Dia of your tire 31" + the width of the tire 13.5" or a little more. The wheel size 15" has little consequence. The height of the tire determines the length of the side chains 31" x pie 3.14 = 97.34" long or 97.5" a 33 " dia set would be 103.62". These lengths will shorten about 6" as the side chains go on the side of the tire not around the outside. The cross chains need to be a 4"-6" wider than the width of the tire These dimensions are all ready figured into the size of the tire chains.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
