what size tires are you guys running for your joyner 650s. Mine has a turbo and runs great. i heard i should try running 22" or 23". is this so? does the rear end drag?

i have never been duning and the tips are greatly appreciated. thanks in advance.

I have 23x10.5-12 6-paddle tires on my 650 and find they dig too much with so much weight on the rear. If you plan on riding in open space at speed, they do great. If you do tight loose sand stop and go, you will find that starting out will dig before you start moving and uneven ground will not give you much clearance. Forget about going in reverse with paddles so plan your lines carefully. Since the tires were shorter, I found I was able to use one gear higher than the stock tires and the engine would labor less in soft sand.

My stock 25x10-12 tires have a bigger footprint in the sand and dig less while providing more clearance. Since the tread is bidirectional, reversing is not an issue. I did reverse the tread direction on my tires and find they work better on sand.

I would suggest 26x12-12 paddles or something close to that to keep the footprint big. Luckily I got my paddles from the previous Joyner owner, so I did not spend my money on these.

The paddle size that is recommended is 26x11x12 on the rear and if you want fronts they are 25x8x12.

I can have them shipped right to you. The rears retail for $100 each and the fronts are $117 but I can do a little better than that.

Does that include the wheels or just the tires?

Just the paddles.....

That is the way it is listed in parts. I can double check though.

I made a call today. Prices quoted are just for tires only. I think the wheels are an additional $65.

Im looking at getting the dune star sand paddle by ITP. They come in a 26/10-12 which I think would be a good fit. However my question is that I have a stock 650cc sand viper and the only place I use it is at the dunes in real loose sand. Do you think my sand viper is too underpowered to turn the paddles while going up a somewhat steep hill? I know my sand viper will never be going up any big hills like the banshee's but I want to be able to go over most of the hills out there. Are the paddles a bad idea or should I wait to put them on after I install the turbo? Thanks for your advice.

My stock engine with stock tires, I am shifting between 3rd and 2nd on sand. with 23" paddles I use 3rd and 4th. Once you have a turbo, you should be able to use top gear with 26" paddles.

Post subject:  Tire size question

Is it a bad idea to run 22/8-12 tires in the front and 26/10-12 in the rear (four inch difference) on my 650cc sand viper? Compared to the stock tires which are 25/8-12 in the front and 25/10-12 in the rear....I only ride in the dunes so the fronts would be the ITP sand star, very smooth tires with the dual rib going down the center, and the ITP dune star in the rear. Would it be bad to have a taller tire in the back and a smaller, but same width, in the front? Cuz I know the stock tires are both the same height. How would this affect my gears? Thanks.

Running different size front tires does not affect your gearing, but will effect your front to rear weight balance and change your footprint. I suggest 25-27" front tires with the largest footprint to keep your front end on top of the sand.

Rear tires will affect your ratios. I love the lower gearing with my 23" paddles, but hate the lack of clearance. I suggest you stay with 25-26" paddles in the rear.

If you run different size tires front and rear, try to run taller ones in the front to keep the weight over the drive wheels and the front end light.

oh ic....so by having the smaller tires in the front the frontend would be lower to the ground making the weight of the buggie be somewhat pushed downwards over the front?

Yes - Plus you will have less surface area with smaller tires so the front will sink even more in soft sand.

Here is an interesting story about running paddles on a heavier UTV:

Although I had good success with my Yerf 150 running big tires on all four corners, I didn't think about an 1100cc UTV having the same issue. Since my last post, I have moved the 23" Paddles to the Joyner 250 with good results and now run 26" paddles on the Joyner 650. I do lack power with my stock engine setup, but am able to go more places now than the 23" paddle or 25" trail tires I have used in the past.
