new tire time -TT250
Looks like I'm going to need some new tires for next season, these OEM ones appear to be worn down enough after 5k miles. My riding is about 80-90% road, 10-20% dirt, so I'm hoping to find something a little more street oriented but just enough to keep me up on some gravel roads here and there. I just don't know enough about the tire codes, tubes, etc, to make an educated decision, so this is more about learning something rather than straight up "what tire should I get?"
Specs say front/rear is 3.00 x 21 and 4.60 x 18. I contacted Dunlop about a specific tire and they said it'd be 90/90-21 and 120/90-18, respectively. Are these just two different ways of saying the same tire size? I see the same numbers listed on CSC for their Shinko E804/E805 tires, so I assume that's correct. What's the deal with tubes (in my best Seinfeld impression)? Can you use tubeless tires on a rim that originally used tubes? Are the tubes measured for the rim, or for the tire? (meaning, can I use my old tubes in whatever new tire I decide on?) |

I put Shinko 705s on my hawk...if I remember correctly.
yes, it's just a different way of defining tire size. yes, you can use a tubeless tire, but you must run a tube in it due to having spokes. Tubes are more often measured by the 3.00 or 4.60, but do google searches and there's plenty of choices. As for replacing them, I'd suggest it, but it's not absolutely necessary. |

So if I were to use it tubeless, do you mean to just throw the un-inflated tube inside the wheel as protection for the inside of the spokes? Sorry for the ignorance on my part, I've done some research and feel like I'm going in circles.
And am I officially looking for tires that fit these specs? 4.60 x 18 aka 120/90-18 3.00 x 21 aka 90/90-21 The Shinko 705's look like more of what I'm aiming for as opposed to the 804/805's, which seem a bit beefier of a tread. Looks like revzilla has my front, but not my rear, if my above statement is correct? https://www.revzilla.com/motorcycle/...&sku_id=594634 |

with spokes in the rim, a tubeless tire is not an option. you must run a tube. manufacturers sell "tubeless" tires. I've never truly understood the difference.
either way, you need to run tubes in any tire you mount. |

Tube rated tires have smoother interior walls to reduce friction with the tube. You can still run tubes in tubeless tires. I have for many many years and thousands of miles.

Been going through sizes to see what's available, and I came up with this. Not asking if these are recommended (unless they're vehemently not), I'm only asking if I'm looking at the sizes correctly. I had trouble finding the Shinko 705's for the front, which led me to the 700's.
If I bought these, given my specs, they'd work right? And I wouldn't need to get different tubes or anything? I just don't want to end up getting something and finding out the hard way that I messed up the aspect ratio or something and got the wrong ones. https://www.rockymountainatvmc.com/t...orcycle-tire-p https://www.rockymountainatvmc.com/t...orcycle-tire-p |

I have those same tires on my Hawk. I love them. My riding is similar to yours. Mostly paved and some dirt and gravel roads and dual track. The only thing they struggle with is thick mud and deep sand, like most dual sport tires.

700's ordered!
Does anyone know of a good video on the process to replace the tires on a bike like this? I have new tubes I got from CSC, so figured it'd be better to replace those as well and keep the old ones as spares. The problem is I've never done this before, and don't want to waste anyone's time here on step-by-step instructions, as it seems to be something most people here have done many times. I just need to know what materials I need to not screw it up, as I don't have a stand of any kind, so I'm not sure how difficult it will be for me. The other option is to ask my car mechanic, whom often has sweet KTM's laying around his garage, if he could do it super quick and let me watch. |

Yotube has a ton of great videos that show you how to do it. The process is simple, but can be frustrating for first timers. A good set of tire spoons (rounded edges and smooth) are worth their weight, and having at least 3 of them is a must imho. If you aren't comfortable with it then I definitely suggest having your friend help/show you if he is willing.

Sounds like 3 is key, from what I've seen. Yes exactly that, looks simple, but potentially super frustrating. Hah one guy's comment was "he did it in 10 minutes, it took me 2hrs and I almost punched my friend in the face." Maybe I might find a friend with experience, as I REALLY want to get this process down properly in case I need to do it on the fly.
Are rim locks mostly for dirt bikes? I see them in many of these videos but don't remember seeing them on mine. I also hear about using a dedicated lube, but have heard of a little dish soap in water in a spray bottle, any pros/cons to those? And what's this I hear about using powder? |

Like megadan said, it's mostly for motorcycles that are going to be used mostly off road and will be used with low psi. For these motorcycles is not needed, but if you want to have rim locks, you will need to change the rims, for ones that take rim locks. Don't forget to use rim strips. |
