Have had these tires for many of years. They are excellent if you have a 400CC or less quad. I have friends that are on their 10th trip to the dunes on these and are still looking great. If you got a banshee, 450, or raptor, I wouldn't get these, but for lower powered machines they are great. I am faster with these than a set of more aggressive paddles. Installed on a LTZ400.
These are sold individually and do not include wheels. The best bet for wheels would be to go with ITP T-9 Pro's. The wheels are also sold individually. Make sure you profile your unit when selecting wheels so you receive the wheel with the correct bolt pattern and offset. The correct size wheel for this tire would the 8x8.5 if you go with the ITP T-9 Pro wheel. If you use our wheel and tire builder we will mount the tires for you and it saves you some additional money also.
These tires are sold individually. we do sell wheel/tire packages, that include 2 tires, 2 rims mounted. but the product link for this question is just the tires only.
here's the link to our wheel/tire combo deals.
Going from stock 18's to 21's is a big change especially in the sand, if you like the tires try re-gearing it first, going down 1 in the front could help a little and its fairly inexpensive. if not see if a friend has some other sizes to try before you buy.
If you'd like these tires to come mounted up on rims and ready to be thrown on your bike, then you will have to purchase and specify a wheel and tire combo when ordering online. What you are looking at here are just the Kenda Sand Gecko tires themselves. So if you'd like to make sure that you are getting the correct tire/wheel packages, then I'd recommend giving us a call so that we can better help you out over the phone!
