I‘ve been looking online and I‘ve found front tires that say they‘re the same size as my rear and rear tires that say they‘re the same size as my front. As long as the size is the same (100/90/19) would I be fine putting a tire labeled rear on the front?
Unless you have a specific problem you're trying to correct you should NEVER add oil treatment. Fresh oil has just the right amount of additives in it. And if you change it on time, you'll never need additional additives. Plus, if you got a teflon or ZDDP additive, it will do more harm than good. Stay away from additives.
particular, the bike producer ships a definite tyre with the bike, yet they do no longer make the tyre themselves; this is often between the large names. as long as you get the surprising length and velocity score, this is in basic terms a count of selection. Tyres variety quite in terms of dry grip, moist grip, tread intensity, off-highway / green laning skill, cost, how they experience once you lean it over, how long they final etc. you have have been given to think of, what's maximum mandatory to me? once you're using in all weathers - which I doubt, as you have have been given a gixxer ;) - then moist grip is a good sized situation. in case you do an impressive variety of summer time miles or hoon around for all time, perhaps an prolonged-lasting compound concerns greater. perfect wager: get on an vendors communicate board and ask there. i might say, attempt some thing distinctive only for the sake of it. My trailie got here with Bridgestone Trailwings as familiar and that they're a nightmare in the moist (they are not prevalent as deathwings for no longer something!) and after asking around, I switched to Michelin Anakees, that are 10x greater useful, for me a minimum of. those tyres are not ideal on your bike, yet you notice what i'm utilising at. save it bright facet up!
I would not do it. Biggest difference will be the tread pattern on a front tire will be a balance of forward motion and turning ability. A rear tire will be geared towards putting power to the road and not at all for turning. If you were to get in an accident and they noticed the bike was mis equipped they might not pay your claim. If a tire could go on front/rear they would not designate it as rear only.
Fronts track better for steering, rears push better for traction/ Dual sports are weighted about 80% for the street, closer to street tires than dirt but can ride off road.
you are better to use top quality oil and there is no need for additives
