Help choosing tire size

[Evan]

I'm going to order some tires this week and I could use some input. I had initially planned to use 110/90-18 front and 120/90-18 rear but in the tire I'd like (bt-45) they only make an 80 profile in the 120-18 size. Should I go to the 110/80-18 front to match the profile or stick with the 90 in front.

110/80-18 = 88mm tall
110/90-18 = 99mm tall
120/80-18 = 96mm tall

Ah... I think I can rule at least one of those out, unless you're planning on changing your rim size. If you have 18 inch rims, you will have much more success with an 18 inch tire. The 19 inch tire may have trouble holding a seal...

Oops. That was a typo. Fixed it now.

I think I found a solution though. Bridgestone makes the sizes I want in a different speed rating that wasn't listed by the website I was on. I found somebody who sells them though.

sorry to interrupt your discussion, will Avon am26(front, 110/90-18) and Avon am42(rear,130/90-16) will work good together ?

It's usually best to match tires. If in doubt check with the manufacturer.
