I'm interested in a set of aftermarket tires and wheels for the 400EX. I've run into the problem of tire roll when cornering with the stock set. I'm leaning towards Douglas Red Label offset rims with Holeshots, Shredders, or Razors. Anyone running this combination? Or better yet, does anyone have a better suggestion to the tire roll problem? Thanks in advance....

Lightninn,
Try more psi in your tires that might help. If that doesn't help try the RAZR's they are an excellent tire. I love them. The fronts turn very good and the backs provide excellent traction. They are much better than the Holeshot.

 

The roll you speak of is pretty common to the stockers.They are four ply,Where as Holeshots,Shredders and Razors are six ply.Hence a tougher tire.

As for me I'm running XCT's all the way around and love that ground clearence.And almost no roll.(drop a tooth on the front sproket)

As for JD250R the RAZR's are an excellent tire,But they are a harder compound where as the holeshots are a softer compound which can bite better,But wear out faster.Aaaaa- I think it's a personal preference.

 

You are most likely getting the roll from a combination of two things, assuming you have the stock front shocks. The stock front shocks on the 400 are capable of easy trailriding but if you start to push them you will get excessive roll. The same comment holds true for the stock front tires. The only way you will eliminate all of the roll is to upgrade both. As far as the tires, I can speak for the Holeshot or Razr. No experience with the Shredder. Both the Razr and the Holeshot will help significantly with roll and both have their good points and bad. Holeshots are a softer compound than the Razrs and therefore wear quicker but by being softer will give a slightly better bite. The Razr is harder therefore wears longer and and is easier to break loose on packed surfaces. The Holeshot is slightly taller even though they are both rated as a 20" tire therefore slightly better ground clearance is provided by the Holeshot. In sticky mud, the Holeshot's tighter pattern tends to pack-up whereas the Razr will clean out. Razr's tend to be more susceptible to sidewall damage in rocky conditions. Holeshots have a wider range of sizes currently available but Razr has prototypes of similar sizes that are not currently available but should be soon.

I have a 2000 400ex. I run 8-10 psi in all of my tires. They don't roll over then at all. At that point, you can soften the suspension a little to regain the original smoothness of the 4 psi tire ride.

 

Hey thanks guys for all the input!! I'll try increasing the pressure for now until I can get a new set of tires and rims.
