widest tire wheel that will fit 17mm hex
 

whats the largest (widest) Low profile tire and wheel combo that fits a 17mm hex

Probably a 40 series Wabash wheel with the 40 series tire of your choice on it.

Phaltlines... may not be the widest, but they are the lowest profile.

i had no idea that you could get 40 series or wabash in 17mm.
what about the widest wheel tire thats not 40 series that still use the 17mm?

I got a set of the WB's in 17mm, they are 1/2"offset like losi wheels, you will add 1" total width at least to your revo

axial oversize rims also fit 40series tires and have 17mm hex

Axial
 

Yea the Axial beadlocks are my (17mm hex) choice, and the tires depend on what kind of surface your planning to run on. Any of the Proline 40 series tires will fit.
