Can't go much wider than original tire.

Lawn and garden tire made for use on grass at speeds below 10 mph. If you're going to run a slick, get a go-kart slick, not a L&G tire.

Something like this...

You would probably need a smaller sprocket to use with a small OD kart tire.

Aren't the kart tires usually much wider sidewall wise?

I'm worried they wouldn't fit on the rim I have and would hit the sprocket. FWIW I ran the tire I linked on my gas bike. It worked ok near as I could tell. Had it will over 50 many many times. Not saying its right or a good tire. Just that I knew it fit.

This new setup has 3x the torque instantly as my gas bikes so a nice soft "Race" compound would be great. If I could get it to fit.

Would something like this work better? Anyone know of any "Soft compounds" in these types of tire?

Any suggestions for a skinny motor cycle type tire on the front? Trying to ditch the balloon tire and get something a little more drag race looking.


thanks!

Here is that oregan L&G tire I linked on my gas bike.

That is a pocket bike tire and it will fit a stock 6" wheel (Baja, Coleman, Monster/Mega Moto, Motovox, etc.), made for Cat Eye type pocket bikes. They came with 13x5.00-6 on the front and 13x6.50-6 on the rear, the 6.50 is too wide for a stock minibike wheel, I've seen them mounted on stock wheels but it screws up the profile by drawing the tire beads in too far (I call it puckering), makes the tire crowned in the center of the tread. A stock minibike wheel can be widened an inch for a much better fitment of the 13x6.50-6. Be advised that these pocket bike tires aren't actually 13" OD, they're only around 11" - 11.5" OD, I've had both sizes in 2 different tread patterns (I've seen 4 different tread patterns) and I measured them years ago. I've also had 8" pocket bike wheels/tires (made for X-7 pocket bike, 90/65-8 and 130/50-8) and they're only around 12" - 12.5" OD. Pocket bike tires would be a much better choice than L&G tires, IMO, due to the rounded profile and higher speed capabilities but they're very low-profile so they have a small OD. You may want to consider larger 10" pocket bike wheels/tires if your budget allows (may need to use pocket bike brake rotor and adapt a #35 or 420 sprocket to fit, my 8" wheels had a different bolt circle than Coleman wheels and pocket bikes use some metric size chain). For a drag race look, you could go with Jr Dragster wheels/tires...

Lawn and garden tires... I don't consider tires with an A1 (3 mph max), A2 (6 mph max) or A3 (9 mph max) speed rating as "race tires". Most L&G tires have one of those three speed ratings. L&G tires are not constructed for high speed use and the rubber compounds are formulated for use on grass and dirt, not pavement. A tire experiences a lot of centrifugal force at speed, watch top fuel dragster tires grow as speed increases for an extreme example, L&G tires aren't designed/constructed to withstand much centrifugal force because they aren't subjected to it when used as intended by the manufacturer(s). Don't know about you but I wouldn't want to experience a tire disintegrating at 60+ mph...

I used a metric scooter tire 130/90-10 for my dragbike.

Cool! I'm going to put 110/70-16 motorcycle/scooter street tires on my Polarna M6 Pro ebike which has OEM 20x4 knobby tires. Sounds crazy, I know... Bicycle wheel/tire sizes are screwy, 20" bicycle tires are 16" ID at the bead. I've watched several YouTube videos of people mounting this size on 20" fat tire ebikes, seems to work. I could go with 100mm width and/or 80% or 90% aspect ratio but the 110/70-16 looks great, going from knobby "balloon tires" to relatively low profile street tires will drastically change the character of the bike. The M6 Pro has one piece aluminum wheels so I'm going to try mounting the tires tubeless (haven't seen a video on that since most have wire spoke wheels and use tubes), hopefully they will seat.

Do you know of any taller than 11" though? I don't think a 60T gear will fit on it and I'd like to have a 14" plus tall tire if possible.

Glad you mentioned this ^^^
A lot of this is going to depend on what size wheels you want to run.
I chose to stay with 6" diameter wheels, which was a limiting factor for how tall of a tire i could run. The 11.00-11.50" tire height was the tallest i could find for my wheel size.
Jr Dragster rear tires are 18" tall by 8" wide. I know of 1 guy who modified his bike to take a Jr Dragster rear tire, and it looked real good! But that is something i did not want to do to my bike.
There is also a certain class of racing karts, i can't remember the name now of course, that had taller tires. Guy from MA was running those tires. His bike was super fast, name on here was majunkman i think. Name is Herb

Why does it have to be a slick? DOT approved scooter tires are taller and rated for the speeds you can achieve. If you use scooter wheels, they come with brakes, too.

For drag racing, soft compound slicks are certainly ideal. And they definitely can handle high speeds since they are made for racing karts.
The thing i ran into with the Kart slicks-
The Kart slicks have a nice soft compound, and fit my wheels and setup, but the sidewall is very stiff due to the karts taking turns at high Gs. Drag racing slicks have a softer sidewall since they are not taking any turns.
Air pressure was very finicky with the kart slicks because of the stiffer sidewall. Too much pressure and was easy to blow the tire off under launch.
The Jr dragster slicks have the soft sidewall, but are huge at 18" x 8".

Compound softness as mentioned and for the tire patch contact to the ground VS a standard rounded "motorcycle" tire.

This setup is throwing about 25ftlbs instantly at the tire. So its a little different than a gas drag bike. I need all the help I can get in the traction department to get way out in front before the gas guys over power me on the top end.

One thing the jr dragster guys do is spray the tire with wd-40 and then cover with saran wrap the day before. The kart guys have plug-in tire warmers.
My bike has slightly similar power level, finding traction can be a challenge
