Determine Tire Width

Might sound like a stupid question, but how do you determine what tire width you can use when building up a wheel? I know that standard tire sizes range from 1.90" to 2.25"

I ordered a set of 26" Rhyno Lites, as of yet I don't know the width of the tube track, but I am looking to go with the MAXimum tire size (on the rear tire). I would like to go wider than 2.25". How do you determine this width? Is it simply the width of the tube track or does the manufacture offer a spec somewhere (I could not find one).

Standard tire sizes for what, because in DH the standard tire sizes would be anywhere between 2.35" and 3".
I don't specifically know for Rhynolites but I'm guessing you should be able to fit a 2.5".

Well the wheels are XC style so standard sizes will be less that 2.35". Downhill rims are actually wider than XC are they not?

I'd guess I could use a 2.5" as well but I'd like to know exactly how to determine this without trial and error!

I've got a friend with a really narrow front wheel, and he runs a 2.5 on it. Works fine.

The rim doesn't matter as much as whether or not your frame is large enough to take the tire. My frame won't take anything larger than 2.5 in the rear, but most XC bikes won't take larger than 2.35 .

Jason's right, check your frame first and foremost. Mine won't fit anything bigger than a small 2.35" tire.

Good point. I'll get out the old tape measure as soon as I get home. Unfortunately, Norco does not spec out the geometry on this particular bike anywhere (2005 Norco Moment in case anyone's interested). Geometry by Ryan Leech.

Will also need to take into consideration my rear brake - will be mounting a hydraulic rim brake, not a disk which will affect how wide my tires can go.

The more surface area you have in contact with the ground, the more stable your ride. In my case, I'm building up a trials bike and it would be of most benefit to have a wide tire for stability while performing rear wheel moves.

Not exactly ture.

The Mavic D521(Now it's the EX721) is the same width as the Rhyno Lite and the D521 can fit a 2.7 easily.

Also wider tire on the front.

The Moment should definately take a 2.5(if not more), but I wouldn't recommend doing any trials with XC wheels. They'll bend soooo easily. I'd recommend a Mammoth, or take a look at Alex rims.

I've been told repeatedly to go with a set of Alex DX32's but since I got a great deal, I went with the Ryhno Lites. There was still a handful of recommendations for these. Being that I'm a beginner and won't be going big yet, these rims will do me fine.

I whipped out the tape measure last night, looks like a 2.5" should fit snug - I'm worried about 2.5" being too wide for the rear rim hydro though. Actually found a set of Kenda Kinetics 2.35" for a good price. I might just consider going with them!
