I know nothing about tires and had a few questions. I want to save some money and put some used "car or trailer tires" on the front of my AC B. I know stock is 4.00 x 15. What are sizes I can look for in used tires to fit this rim? Bottom line--what will fit? I'm guessing the 15 inches rim diameter is all I can use, but the width aspect is going to vary. I also need to know if I can use a tube in a radial tire. Lastly, what size tube do choose?

just my thoughts.. yes, you can put tubes into radials, 'they' even sell 'radial tubes'( bet they ain't cheap..) you may be better with 'trailer' tires NOT radial car tires. Typically trailer tires are 'old school' design , having a tougher,stiffer sidewall. LT ( Light Truck) tires would be a good choice. Radials have a 'fatter' footprint and would be 'mushy' when turning. The BIG issue I have is steering ! A 3 rib 'tractor' tire is designed to give you STEERING, kinda important. ANY car or trailer tire won't bite into the ground for you,so you'll float and slide when making turns They are great on the pavement for parades though.. Now I do have car tires on my D-14 with loader,it came that way, loaded it's OK, unloaded it does steeer 'real easy'( aka slides a bit..) If you're using the B for farming, I'd rather see you go with 3 rib tires. Cheap, 'offshore' 3 ribs will be far better than any 'car' tire. Now knowing how popular the B is here, I'm sure 'words of wisdom' will soon be posted...

Thank you. That makes very good sense about turning and biting into the ground with the 3 rib. I never considered that. How about for mowing? Would it be better with a trailer tire? Also, I still need to know how wide I can go to on that little rim. ------------- 1940 B "Lucy" 1941 B w/ Woods L59 "Flavia" 1942 B w/ finish mower "Dick" 1941 C w/ 3-point "Maggie" 1947 C SFW w/ L306 "Trixie" 1972 314H |

if you mow, then a 'car' tire is more like a 'turf' tire.won't bite into the ground and leave 1 or 3 grooves. I KNOW my snowblowing rider will NOT steer on snow even with 400# on the front due to the 'turf' tires. at least mowing dry, warm grass you'll be able to steer...

Steve, I've been looking at the same thing for my C and now my CA. I never got a response on here about it, but I'm thinking 1.95x15s. I figured some of the guys that HAVE road tires on theirs already would chime in and say what size they are but no one ever did. I hope you have better luck than I did. The only thing I will be using the CA for is cutting grass and I want LT tires on the front as I don't like digging up the grass with the 3-rib. Good luck!! ------------- "Allis-Express" 19??

Bring your old tires and rims to one of those used tire places. They will get you going. ------------- AC 6080 (8030,7060,200,175,D-17HC, 6040,160,6140 all gone) Farmall 1066 & 656 Hi-Clear (for sale), White 2-62 High Clearance, JD 4255 Hi Clear. |

You can get a 5.00x15 implement tire. That gives you the float of a car tire with some edge in the grooves to help with steering. It would also look better that a car tire. AaronSEIA |

| I have run car tires on my C even for mowing they suck. A temp spare from an s10 blazer bolts right on rim and all. I broke a rim ( it was welded. When I got the tractor) when to the local Junk yard he gave me two temp spares and I used them for about a month. I was very happy when my new rim showed up and I had time to mount the old tire. You'll cut up more lawn mowing with a car tire than you ever would with a proper three rib. I also use Ag tires on the back they never spin and let you slide down the ditch like turf tires do. |

I used a B for years to mow about 3 acres of grass and never had issues with the 3 ribs cut up the yard. From your post is sounds as your main goal is to save money. I know that tires do cost good money but you must also remember that they will last well over 20 years cutting grass. I installed new 3 rips on my CA in 1998 and used it for every part of my farming duties and they are still in good condition. ------------- Thanks & God Bless Dennis |

Because radial tires flex more than bias ply tires, radial tubes are built stronger to survive the extra flexing. That is surely more of a concern on the road at 70 mph than in the yard and field at 5 mph. Back before sometime in the 50s if I recall the date correctly, tire sizes were the rim width and rim diameter. The tire was wider than the rim. The industry changed to the width designation being the widest width of the tire, wider than the rim. Then with radial tires the maximum width is metric with a factor of height to width ratio and fractional inches rim diameter. A place on line like Miller Tire should have translation tables. And tire manufacturers have tire handbooks that can be read on line or downloaded with the details and real dimensions and rims that fit all their tires. Gerald J. |

I put the car spare tires, donut tires on the fron of a farmall A with a 5' mower under it. They steered better than the tri rib, and didn't tear up the turf. I just bought the cheap tubes at TSC. They were not for radials, but I figured I wouldn't be driving down the road at 55 so they would probably be okay! They were great. oh, and they were a perfect fit for the rims. ------------- D14, D17, 5020, 612H, CASE 446 |

Thanks for the comments guys. I'll look for some donuts. Usually those are expensive though. ------------- 1940 B "Lucy" 1941 B w/ Woods L59 "Flavia" 1942 B w/ finish mower "Dick" 1941 C w/ 3-point "Maggie" 1947 C SFW w/ L306 "Trixie" 1972 314H |

If you are trying to cut costs use the junkyard donut spares but you will be a lot happier finding some not so expensive tri ribs. ------------- Just an old country boy saved by the grace of God. |

I just checked with my old tire supplier, 400x15 3 rib tires should cost you around $45.00 each + tube. That price would be mounted on the rim - you keep the old tires. |

Two brand new ribbed tires with tubes mounted on my AC 720 for less than $100.00 Cdn, using them on frozen ground to blow snow and they work great. |

I try to convert my all my fronts to tubeless. My David Brown (16 inch fronts) rolls on two tires I picked up from the dump. They were too worn out to run on a pickup but still fine for my tractor. Holding air is the main thing!.Converting to tubeless is not hard to do if your rim hoop is decent and the inner sealing flanges and the valve hole in the rim band are good and resonably smooth. Deep rust pits are a problem, but they don't have to be perfect, especially if you have a nice thick coat of fresh paint on the rim. My 54 chevy pickup was tube tires when new but has long since been running on tubeless tires. ---------- I helped my father in law put tempaspare donuts on his Farmall. We got them cheap at a local junkyard. Five $ per, as I remember. Almost nobody wants them so they don't see them as valuable. They are narrow and have a VERY stiff sidewall, though, and can be tough to get onto the rim. And they have very low profile. This would also be a good place to say MAKE SURE that the rim diameter size and the tire size match before trying to mount a tire and air it up. Close is not good here -- and a 16.5 is most definately not the same as a 16. Mismatched tires and rims have exploded under pressure and hurt people badly. ------------- Chris in NE Florida |

| get just what truckerfarmer said you will not regret it. my garden tractor has tri ribs and it does not chew up the grass when i mow, and it will turn in the garden good now or blowing snow, be fore it would not turn good at all just push and chew up the turf . all of mine has tri ribs from the littlest to the biggest |

5 inch wide tires are 125 mm wide...... a 175 mm tire is 7 inches wide.......... any auto tire is going to look "wide" compared to the 4 or 5 inch rib tire..... If you go metric, try to stay under 185 mm wide....... and an 80 series tire would look much better ( and taller) than a 65 or 70 series tire... all 15 inch rims. ............. 165 x 80 x 15 would be good. ------------- Like them all, but love the "B"s. |

Care for them front tractor tires can last 30 plus years. I'm 41 and willing to bet the fronts on my D17 are older than I am. I'm cheap also but learned mt lesson on pinching pennies on tractor tires. ------------- 8030 and 8050MFWD, 7580, 3 6080's, 160, 7060, 175, heirloom D17, Deere 8760 |

| WF tires seem to last a lot longer than NF tires. Perhaps because the turning radius is engineered into a WF, but impossible to do with a NF. |
