Default Question about front tires

I tried to have a 120/70/19 but it would not open out to the rimn and seal. Just too big for my 2.75 inch wide rime. Who know the largest tire I can fit on a standard width 19 inch harley front wheel. I have had a 100/90/19 and want the widest I can get. Will 110/80/19 fit.

What device or devices were used to expand the sidewalls? I've seen the nutty lowriders around here using some freakishly narrow tires on wide rims on their cars (I mean tread widths half the rim width). While this is a stupid way to achieve a really stupid looking, poor handling ride in my opinion, it's pretty common. I really don't know what devices are available for mounting bike tires, but it seems to me that what you're trying to do shouldn't be that tough.

install the tire, seat the bead on one side, squirt a shot of ether in tire and touch off with a match. standard precautions apply! keep your face, chin whiskers, etc,etc out of harms way, keep your fingers out of the damm thing also.

Ralph, here is the thread where I installed what I believe is the biggest tire you can put on a stock front rim. My rim was the stock 19" cast wheel. Hope it helps, there are pics of the installed tire and you can see how close it came to the fender.

Good luck, Chris

If you have a 2.75 rim you should be able to mount a 120 on it. I have a 2.75/18 rim that I used to have on my bike and 120s fit it no problem, but really a 120 would like a 3" rim.

I'm running the stock 2.15 rim now and I have a Avon 110/90 19 on it that fits fine. It's really big ass. It's as wide as some 120s, and might not fit the stock fender. It makes a Dunlop GT501 100/90 19 look like a little skinny runt.

I think the problem was the 70 height coupled with the extra width. The tire was 5 inches wide and after putting it on it looked wrong and the one side would not roll out to the edge. It stayed tucked under. I ordered a 110/80/19 and that one has to fit. I used to have a avon venom up front in the same size. I hope the 140/70/16 works on my back. The 70 seems to like a wider rim.

R, how many miles did you get out of the Venom on the front? just curious cause i just bought new front/rear set Venom x.

Bad news: had to get a new front wheel bearing rightside was bad, and it won't be here till tuesday. Running the spoke wheel in the meantime.
