Default Looking for help on tires

Hi,

I am building a custom pedal car, and need help finding a specific size tire. I have spent a lot of time researching but have come up empty handed. Figured I would join here and ask the pros.

I'm looking for a slick tire that is between 7"-8" tall and around 3"-5" wide. Does a tire like this exist? If so, what size would it be? I'm hoping to find a cheap used set with rims.

Something with a profile like the attached as it is a vintage build.

Thanks

Thanks, I hope so! I spent a lot of time searching the internet but came up empty handed. Looking to put this pedal car together for my first born who will be here any day now!

Although I have not specifically found what you are looking for, perhaps the direction you need to go is 1/5th scale RC vehicle parts. Keeping in mind that 7 inches is roughly 177mm, there does seem to be some selection out there. It's the 7" outer diameter detail that is challenging.

7" OD is available... but not in 3-5" width I'm afraid (less than 2" usually)
can be found on motorized skateboards [offroad type]...
yes there are maxxis slicks for that as well

Some mobility scooters have fairly small wheels in the 7-8" range, but none I know actually has wide slicks.

So you have to make a decision I guess..
Do you care about the OD or the width..
since you can have either, not both as it seems.

10" OD is easy.. just saying

Smallest slick I can find is the CST (chengshin tyre) C-190
a classic kart slick
in 9 x3.5 - 4

9" tall (just under as always) 3.5" wide for a 4" rim.

Oh also available as carefree (solid tyre):

OH look!!
indeed there allegedly IS a smaller CST C190 ...
https://www.ebay.com/itm/CST-C-190-S...gAAOSwQFhbXgGX

8" tall (spot on!) 3" wide (spot on!) still for a 4" rim...

I am baffled!
as it is listed on their website.. I'm confident the tyre DOES EXIST!

Thanks for the replies.

I would have to stick with 8” tall or less as I don’t want to modify the car body.

It looks like the tires you posted could work. I will start looking around for them.

Thanks again

Just remember, the bigger the contact patch, the more friction, particularly when cornering. Could get hard to pedal with 3-5" wide slicks, especially if it's for little legs.

That's why pedal cars usually have very skinny and/or very hard (plastic) wheels. That, and weight, which also makes it harder to pedal.
