is it possible?

[demonoid369]

can you put 40 series tires on a Wk axle? and if you can, do I have to get a stronger servo to steer?

Yes you will need a stronger servo. I have a buddy that narrowed a set of 40's so that they would fit. with out doing this they rubbed bad

Sure.....you can put almost any wheel on any axle with the right adapter. Yes, you'll need a bit stronger servo than the stocker to steer those meats.

You can bolt them up with the right size hexes 14,17 & 23mm. (Duh). But in order for them to actually work, you have to have a wheel with little to no backspacing (where the wheel hex is almost flat on the inside of the wheel). My wheely king came with a set of 14mm hexes. I assume they all did. Anyways, I bolted up a full width set of proline mambos with some moab xl's onto the king just for kicks. The tires were in contact with the shocks and links. So, it can be done, clearance will just be a major issue though. I was definately thinking that with some narrowing of the rims, it would be a cool look. But with the stock wheelbase I think the tires would be touching, depending on what size you go with. And of course, you will want to go with a MUCH stronger steering servo.

FYI- I am rebuilding my WK as a basher, and used some old clodzilla links I had to extend the wheelbase to 14-15" (haven't finished yet). I am either going to try to adapt some clod wheels/tires (using the 12mm hexes and the tamiya hubs) or I want to run some Maxx rims/tires with the 14mm hexes. But no matter which route I go, I will have to mod the rims to have little to no backspacing, as previously stated.

Sorry so long winded.
