What size tire is this?

[jchristy456]

I looking for some tires excatly like this. I email the monstercraftsmen guy several times asking them what sizes these were and nobody ever got back to me. Anyone wanna take a stab at it. I'm also looking for the correct tube size as well. Thanks a million fellas!

My guess is the rear is a 5.00-16. The front looks to be a 19 inch wheel so the front is a 4.00-19. Maybe a 4.50. Look to be Firestones.
Tubes would be the same size as the tires. Tubes may have a metric size. A metric 5.00 is a 130. A 4.00 is a 100.
Just googled "Coker Firestone Replica Motorcycle Tires" With a bit of looking around they make a 4.00-19 for the front and a 5.00-16 for the rear.
They cost few bucks but if that's what you want go for it.

I was going to guess 16 on rear and 18 front.

yep they say firestone rear is 5.00 x 16"
front harder to tell 4.00 x 19" it seems to rise above the fender mounts the same as my 19" wheel

I went back to the pic and blew it up a bit. The rear is a 16. I measured the rim from bead to bead got 93 mm. Measured the front the same way and got 109 mm. 93 divided by 16 is about 5.8 mm 18 x 5.8 = 104 mm. 19 x 5.8 = 110.
I have found this procedure works for determining sizes of thing in pics.
What do you think? Does it work?

Yes since we know the value of the rear wheel is 16"
I'll have to store that in my memory bank.
LOL maybe I should write it down.

Reading the tire markings, I see 5.00-16 on rear, 4.00-19 on front...

I have a 500 x 16 Avon Speedmaster on the back of one of my bikes. Warning that the chain does slap the sidewall with that setup. I have 1/8 spacer shims on the sprockets on another bike and that helped with a 450 tire. Rim width plays into this too.
