What size tire should I go over my stock radials (rear only)? I do trail riding with a lot of hill climbing (especially when i extend my swingarm) do bigger tires take away from power at all?

 

Razr are alright for trail, but flat suck in sand. If you are hill climbing on dirt, they should be fine. My banshee didn't like them (it kept trying to blow them off [img]i/expressions/face-icon-small-happy.gif[/img]). Overall, I didn't like them as well as shredders, holeshots, or fast trekkers. I had the 20inch.

If you increase tire size, you increase the final drive ratio. You don't really loose power, just acceleration. Some tires actually eat horsepower due to design and weight. Todays performance tires are light so they aren't as bad.

 

I went with the 22 inch Razr's in 6 ply on my Raptor because I had to have that extra 1 inch of ground clearance for trail riding. I also went to a 12 tooth front sprocket, which pretty much evened the gearing back to just slightly lower than stock. I can make it through a lot of snow that my 400ex with 22 inch Holeshots gets stuck in, so they are working great...

Good luck,
Lorrin

 

the Razr2's look pretty good... dunno if they hook up or not. I also like the 'Pure Sports-Realtors', and the Spider-Trac's. I've ridden spider-tracs on a 500 scrambler modded to hell and they hook up really nice, provide great traction, and are very tuff. Realtors are very similar to the Spider's. This was a 2001 500 4x4 scrammy and it could wheelie on sand with the Spideys.

 

Quadracer, I tried Realtors on my banshee. Didn't hook that well. Tread spacing was too wide.

The only tire I have found to hook in loose gravel is the fast trekkers. They seem to be the best all-around tire.

 

ever thought about putting the stock 400ex 501's on the rear thats what i have on my raptor and they hook great the only drawback is that they arent very puncture resistant.
