Tip & How-To about Cars & Trucks

When all else fails to inflate a tire

Once in a while you will have a tire that will not seat on the rim because the rim is too wide. Even with an expander or other methods of introducing air to the tire. it just will not seat.

NOTE
The following method may be hazardous and probably not OSHA approved but sometimes it is the only way, believe me. Please use caution when using this method as injury could happen. Please wear safety glasses. And have a fire extinguisher close by.

With the tire and rim on a tire machine fully seat the lower bead the best that you can. Spray a 2-3 second squirt of starting fluid into the cavity of the tire. Take a can of carburetor cleaner and using the red spray nozzle in one hand, or have someone help, and with a lighter in the other hand start to spray the carburetor cleaner into the tire cavity and as you do so, ignite the spray.

DO NOT STAND CLOSE TO THE TIRE.

The ensuing expansion of the carburetor cleaner and starting fluid should expand causing the tire to be seated and sealed.

My 2004 GMC Yukon came with 265 70/16. I put on 245 75/16. Was this ok to do, or am I gonna have problems?

you could have problems as the tire may not be wide enough for the rim resulting in tire failure during cornering
the side wall may be sitting too straight up even out at the rim
best talk with a tire shop as they know the best size tire for the rim or the specified tires for the vehicle will be on the decal on the door or door pillar
the 265 dimension is the rim width ( problem area)
the 75 dimension is the distance of the rim edge from the road ( not a real problem but can affect speedo accuracy)

remove the hub from the back wheel

Several ways will work. The wheel shrinks in real cold weather, which we are now having. If you use a large sledge hammer to hit the inside of the tire or wheel, it will usually get it off. Be careful not to dent your wheel rim where it seals the tire. Hit it inside of the rim. Or you can use a large piece of wood, or ball bat to hit the outside of the tire, this will sometimes work. If neither of these methods work, then try to heat the wheel with a torch. But be careful and stay away from where the tire seals with the rim. Apply the heat to the wheel close to the hub. This should expand the wheel and release it from the hub.

figure out why my car is wearing the outside of my tires . ihave to put new ones every 6 months

Too much toe in adjustment. The tires are pointed toward the center, I use an expandable retractable tent pole, with normal weight on the tires I check as high as possible without obstruction against the rim evenly front and back same distance from the ground and try to get as close to zero as possible. When there is the same amount of resistance without the length of the pole being changed when held against the rim on one side and brushed across the rim on the other end of the pole first checking the front of the front rim from side to side then the back of the front rim side to side you should see a great improvement in tire life if you have to lean one way or the other slight toe in is better than toe out. I try for zero running radial tires. Keep the pole level and straight as possible.
This should be done with the tires pointed as close to straight line forward as possible while the entire weight of the vehicle rests on the tires. I like to sight down the sidewall of the tire from the front of the vehicle looking toward the rear axle to determine if the tires are pointing straight. I measure adjustment against the rim to avoid differences in tire lettering. There are more ways to do this measuring but this is the only way to do it one manned that I know of without an alignment rack. The rim should be very true running when spinning on the spindle but even a bent rim can cause this method to be inaccurate. If a bent rim is all you have then you must just pick one spot on the rims and then rotate it to the front measure then to the rear then measure.

my 2001 grand cherokee rims are 17" what is the exact size, and what other rim would fit.

Hello, Thank you for trusting FixYa.com to help get you going! The rims on your Cherokee, (and any other vehicle) are measured based on the tire that is designed to fit it. Technically the rims is just shy of 17". They measurement is taken at the base of the lip at the tire seat, ( the place on the rim that the tire seals against.) There are many outlets with rims for sale from custom to OEM, available in almost every city in America. Depending on the look or function that you are seeking, prices range greatly. Good luck, and if you have additional information, questions, or comments please return, and I will respond quickly to your concerns. Thanks again for trusting FixYa.com, have a great day!.
