tire sizing

[Bootboy1488]

does anyone know of a reference guide or feel like typing out their knowledge of tire sizes? my sons manco hyper has 145/70-6 tires on it and i would like something taller. do these exist?

I don't recognize those numbers ! Are they metric???? I'm old school, ya know!
Anyway, here's a handy reference guide that might help to find something. Pretty well lists everything that is used out there.

Unfortunately trying to find a taller tire for a 6" rim is going to be tough. You really need to get the bolt pattern and try for a 7"-8" rim that will allow for taller tires. If there's not a bolt pattern then search for an 8" rim with the right size bore.Does the rear wheels have a keyway or splines? Take a pic of the wheels and post it- I probably have what you need @ a military discount!

I have a set four 15x6-6 turf tires verse your current 14x5.7-6 tires.

the axle is a 1" hexagon. i think 8" rims might make them too tall and the front tires will rub when turning. ill get some pictures and measurements today when i get off work. are axles with this one common?

[metalstudman1]

Not as common as a round axle- but they're good axles. The tire issue you're going to have is that 15" is about as tall a tire as they sell for a 6" rim. Your tires are probably 14"-15' tall already, 7" rims are not very common (kiddie ATV's) and I don't know of one with the hex wheel- maybe someone knows. The next wheel that might work is 8" and that will get you to 18"-19" tall.

if i get off work today a little earlier going to do some searching for these rear wheels, how wide can i exceed the rim width on things like this? thank you for helping me
