Will a 130/90/15 motorcycle tire be ok to put on my all original bike rim

The factory tires said 33 psi. So put 33 psi in all four tires. But if you changed the tires with different tires I would put the psi it says on the tire andthe new tire gives you a different psi than the factory tires I would follow what the tire says check the tire and fill it all up with the same pressure but do t go over the maximum psi you need to be 5 psi below the max.

It may be a tight fit installing back on the bike, but the tire should fit the rim ok.

Call Dynacraft (bike maker) at 1-800-551-0032. My daughter's rear tire was flat and they sent out a new tube for free. She had the bike for only about 4 months. They also sent out a new rear tire as bearing/coaster brake assembly was make noises. The only problem is her original rim was purple and they sent out a silver colored rim as they don't have purple replacement part. I also had to install the tube and tire on the new rim. They only send replacement parts not assemblies.

Can you explain why you think the tires are too big? Do they NOT fit the rims? What condition was this bike in when you bought it? If the brake pads line up with the rims then the wheels are correctly sized for the frame.

the stock vulcan 800a comes with a 80/90-21, the first number is the width in mm, and the second number is the side wall ratio compared to height, the third number is the rim size. ex. the tire is 80mm wide and 90% as tall or 72mm on a 21" rim. So if you are going wider I would measure the distance between the forks in mm and go from there.

You have to remove the entire wheel from the bike. Then change it just like you'd change a front tire... remove oneside of the tire from the rim, pull out bad tube, clean rim, put in new tube, put tire back on rim, inflat tube... good to go. There are 1,000,000 videos on YouTube to show you this process.

The axel has a nut on one end and two bolts or one pinching the shaft on the other. Jack the wheel off the grond unscrew the nut loosen the pinch blots pull out the axel and the wheel falls out Watch wher the spacers go as they have to go back turned the right way. the brake rotor has to be lined up with the caliper to put it back in as you don't push the brake with the wheel off as the pads will have tobe pried open to get the rotor back in. Tring to fix a flat? same as a bicycle except use soapy water don't forget to use water to cheak for leaks then put on the powder on the tube before it all goes back good tire irons come from bike dealers and bike parts suppliers. Screw drivers cause more troble than thier worth. Road going bikes chage the tube patches are Illegal DOT

is it rubbing all the time when you spin the wheel or is it as if the wheel is buckled? or could it be bearings in your wheel. (any side to side movement in it) if not then gotta be tire not seated correctly, you will see this though if you examine it along the rim on both sides, OR the shop put a tire on that was too wide, with either of these tire problems i suggest you go back to the shop that installed it, to re seat it you will have to remove the wheel and deflate tire fully, break the bead seal against the rim. then re-inflate carefully to seal it against the rim, give it a few bounses to help saeting correctly.

Try warming the tire up. Put it in the tub with super hot water it will make it stretch easier. I did this with a twelve inch kids bike it worked sweet.

Tubed tire, right? COULD be a flat spot but my gut tells me the tire isn't mounted correctly. My guess is that if you look at the sidewall of the tire next to the rim on one side or the other, you'll notice that the rubber edge that sits just outside the rim isn't consistent around the entire rim because they didn't seat the bead properly. Typically all you have to do is let some air out and resituate the tire on the rim a little and keep an eye on it as you inflate it. You can overinflate the tire to around 50 to 60 PSI to help it seat correctly on the rim but be sure to reduce the air pressure--you don't want to leave it like that. The other thing it could be if it's doing this at high speeds only is that the wheel is severely out of balance, in which case you would need to take the wheel off the bike and balance it, but my gut still says it's the way the tire was installed on the bike. For those of you looking for the procedure for changing a tire and/or balancing a wheel, this is a pretty good step-by-step guide: http://www.clarity.net/~adam/tire-changing-doc.html
