How do you change lawn mower tires?




-doozer-


My tires are worn badly so I plan to order new ones. How do I get my new ones on the rim? What's the best technique?
Yes it's a riding mower, sorry. I 'm just trying to figure out how to get the actual tire on the rim the correct way.



Answer
Speaking from experience, you can do it yourself, but it's really not worth the aggravation.

Call around to tire dealers that do truck/industrial tires - you'll probably be looking for "turf saver" tires, most are made by Carlisle Tire. They'll be able to order them easily and then take in your rims/tire and they'll put them on for you for a small charge. Also consider having the put an "anti-flat" like Slime in the tire.

The reason I don't suggest doing it yourself is that the small diameter tractor tires are very hard to stretch over the rim. Of course you could do it, but you'll need an assortment of prybars and big screwdrivers to stretch the tire over the rim. The technique is just to push the rear bead on and then pry the front bead over the rim. Usually just a brute force maneuver. Also use lots of dishsoap as a lubricant. Then you'll need to seat the bead of the tire. If the tire is very loose on the rim, this is best done by wrapping a rope or tie down around the tread and tightening it until the bead contacts the rim and makes a seal. You should also replace the valve stem while the tire is off. Better safe than sorry. After all that you still need to get rid of the old tires. They usually can't be put out with the regular house trash.

The tire company I use charges me $6 to mount the tire and $1 to recycle the old one. I need to go to the tire place anyway to pick up the tires, so for $7 more, I save myself an extra hour or so of work, well worth it to me.

How do I remove/tighten my lawn mower tires?

I have a Murray 20" plain old push mower. 2 of the wheels have gotten quite loose and make it very difficult to push as they go on a slant now. I thought I could just tighten the nut but nothing happen. I can't see under the mower to well but it appears to be a normal nut (may be wrong) but when I clamp it and tighten the bolt it doesn't actually tighten. I did notice that the bolt doesn't slide like one would expect if the nut was loose.
Any Help??



Answer
The bolts that hold the wheels on a push mower are shoulder bolts. They have a sort of smooth shaft area from just under the head to the threaded portion, which acts as an axle for the wheel to turn on. You can't tighten these wheels, as the shoulder of the bolt will already be in contact with the frame of the mower deck. What's most likely happened is that the inside of the wheel itself, which is probably plastic, has simply wallered the hole out to a size that allows it to flip flop from side to side or just run sideways. You need to get to either a good hardware or a mower repair facility and buy some new wheels to install. Then you'll be back to mowing straight.
