First time tire change w/ questions
Good evening all,
I am in the process of doing my first ever tire change on my first bike and I am finding the whole process somewhat complicated in certain areas and a breeze in others.
I own a 2014 klx 250s and so far have managed to pop both stock Dunlop’s off of the stock rims, I pinched the front tube when removing and I blame that on my lack of experience. I ordered a pair of shinko 705s as I ride mostly street and have a few questions regarding this before I go ahead with the change.
1. I purchased rear 120/80-18 and front 90/90-21, the front is a tubeless tire and I am clueless as to how this will run with a tube inside, is this anymore dangerous than running a tube type tire? Any disadvantages/advantages of this type of setup?
2. Finding inner tubes in the right side/understanding and converting tube sizes took a lot of research before I felt right ordering. I went for some Michelin ultra heavy duty sized 100/100-18 rear and 90/90-21 in the front. Can anybody tell me if these sizes are correct for my tube setup and if so will the UHD tube type lead to any issues going inside a tubeless tire up front? (Friction/heat issues?)
It’s a newbie question but it’s something I want to get right my first time And most importantly feel safe on the road.
I appreciate any input in advance
EDIT/ just read the sticky, apologies for posting in the wrong thread

Tubeless will work fine. It has an inner membrane that will hold air without a tube. The tire companies say to consider the speed rating one range lower because of tire heat at the higher range, but that won't be any issue with a KLX250 or a 650 for that matter, I have both and never a problem. I also learned what I say from a Bridgestone seminar when I worked at a Honda dealership, so it isn't just internet rumor.
You can run those tubes too. Tubes usually fit a range, like 4.00-4.50 or 100-120 mm. So you are good there too. Be careful putting the tire on. I put a slightly aired up tube (to fit it in the tire) but very little air. start at the stem and work to the top. Use two or three tire tools and be careful when near the end, try to make sure the bead stays in the low center area to get the most room to lever the tire on. I use dish soap/water mix on the tire bead inside and outside the bead. Best I can tell you... others may have other information to help.
