when i bought my bike, luckily the kid had thrown in a set of new tries. The set on bike currently running are... front 80/100 rear 100/90.... The new tires are front 90/90 rear 110/90.
. I'm pretty sure i can run the new rear tire as it just has a bigger sidewall correct? Front tire im not sure if it will fit rim. Have yet to try and was hoping to get some info from some more knowledgable people.

what bike?

Front rims for all full size bikes are 1.6 width. So the 80/100 or 90/90s will work fine

For 125/250f bikes they use a 1.85 rear rim which runs the 100 size rear.

The 250/450f bikes use the 2.15 rear rim for the 110 size tire. If you run a 110 on the smaller rim you will have more roll over thus feeling like a flat at lower air pressures.
