So whats everybodies opinons on tires? Should you go with short, like 18", TT tires, or go with a taller tire, like a 25"?

The way I was thinking is that a taller tire would give you more traction. A taller tire has more contact with the ground at any given point. Also with a taller tire you could get more sidewall flex, maybe giving you the wrinkle effect that you see on drag cars.

Any opinons?

 

On asphalt, traction is not much of a concern unless you are running an extremely long swing arm. Most drag stips have a "launch pad" that is preped to provide more traction than you could need. I get used 18" slicks for free, so I use them, and have yet to spin a tire, despite a 4" over swing arm.

Given a choice, for the same price, I would use a taller tire because I run 1/4 mile and need the taller gearing. I'm topping out at 96 MPH with the 18" tires but they would be plenty good for 1/8 mile drags.

 

Thanks, that was the answer I was looking for. I plan to do a little oval track this summer and this way I can just have to buy one set of tires instead of two.

 

I would use some 4 lug car tires at about 5 psi. Lower the front sprocket to about 11 or 12 teeth, and throw the wheels on. Ford Festiva tires fit on my Honda ATC and my Shee. They are also alot cheaper than Hoosier or something like that, and most likley last alot longer..

Ward, I would use the Lightest rear tire combo you could find!! Unless you have BIG horsePower, a Lighter tire/wheel combo will give you the best times.

Kuhmo makes a 145/10 radial tire that I use for the front. It's an automotive tire that fits stock ATV rims. It's a bit heavier than the slicks I get for free, but it offers less rolling resistance. You can get the from tirerack.com for $25 each. If you want them really light, have the tirerack "shave" them befor sending them out [it's about $10 extra per tire].

Keep in mind that low tire presures on automotive tires don't help for traction, unless they are designed to be a wrinkle wall tire. If you run low presure on a standard automotive tire, you will simply cup the middle of the tire and not get full traction out of it.

If you want to get really trick for the front, order up some 3" wide wheels and put scooter tires on them. you end up with about a 1" wide contact patch so the rolling resistance is almost nothing, and the weight is lighter than anything else you can run on pavement.

 

I thought about that, the scooter tires, but where would I get 3" wide rims? I bet they would cost an arm and a leg.

Thanks alot for the help guys!

 

I think that OMF will make them.

I've spokem to Rudy from R.I.S. Design, and I know that he knows were to get them.

This should be a good sorce for the tires. I think there are tires to suit anything you could want to put on the front,
