how to measure wheels?

[native_wolf]

hello all, i was wondering how to measure and compare wheels? for example a 26" wheel is measured from the 'center to rim' or from 'rim to rim'? the reason i ask and i guess the real question is would a 26" motorcycle tire fit a 26" bicycle rim? im just wondering why a motorcycle wheel and a bicycle wheel would both be called 26" wheels but not be the same size?

The situation is worse than that really, not all bicycle 26 tires are the same. Checkout Sheldon's webpage on this subject

so the only way for me to find out if i can fit these motorcycle tires on my 26" rims is to just buy them then huh?

of the tires? no i havent got them yet, i wanted to find out if they would fit before i got them because they cost alot but i guess i can just return them if they dont work out.

Why can't you find some old tires the same size and try them, maybe borrow a tire that size and try it. Seems like a cheap way to try, your just out some time and not money. Good luck, keep us posted on this.

yeah, im going for a different look than the regular tires but thanks!

most tires have an ISO size number ,like.. 37/559, the last number is the diameter, thats what needs to match, and then a reasonably close width..

awsome thank you! so would the diameter for 37/559 be 559 or 9? sorry if thats a super stupid question i just wanna make sure i get it rite, thank you!

A motorcycle tire may 'fit' a bicycle rim, but I don't know if a bicycle rim would be able to support the bead of a motorcycle tire. Those things are monsters! Back in the day when I rode dirt bikes it was A LOT of work getting a motorcycle tire off the rim if you had to change a tire. At least that's my two cents and something to think about.

37mm x 559mm might be better to just lace the cycle rims to the bike hubs.... :roll:

There are heavy duty moped tires that fit bicycles, but motorcycle tires go by rim size. 26" bicycle tires go by the theoretical total wheel size, including tire. :|

wow your a thinker, thats a great idea!

thank you!

All the ISO/ETRTO sizes go by the rim size doesn't matter what the nominal tires size may be called 26, 27, 28 , 29 whatever(Surly Larry tire is 3.7" 26 nominal but more like a 29" in total diameter when mounted but still a 559 ETRTO size rim). Whether the frame can handle it is the question, and if you go to motorcycle sizes as mentioned the bead will likely be an issue.
